Exploring remote operation of heavy vehicles – findings from a simulator study
- 2023
-
Ingår i: IHSI 2023 Conference Proceedings. - : AHFE International.
-
Konferensbidrag (refereegranskat)abstract
- Fully automated driving has posed more challenges than expected, and remote operation of heavy vehicles is increasingly getting attention. Therefore, human remote operators may have an essential role in compensating for the technological shortcomings in vehicle automation. This poses challenges in designing the work of human remote operators of automated heavy vehicles. This paper presents findings from a research project performed in collaboration between the RISE Research Institutes of Sweden and Scania. In the project, human-automation interaction requirements and challenges for remote operator work were explored through a simulator study. Before the study, three main operator tasks were defined: assessment, assistance, and remote driving. The simulation occurred in a transportation scenario where operators handled ten trucks driving on a public road and confined areas (transportation hub). Fifteen participants completed the study. The results provide examples and insights into classical automation-related challenges in a new context – the remote operation of heavy vehicles. Instances of challenges with situational awareness, out-of-the-loop, trust, and attention management were found and are discussed in relation to HMI design and requirements.

Utvecklingsprojekt för byggavfall : Hur ska avfallsstatistik från byggsektorn tas fram på bästa sätt?
- 2009
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Projektets mål var att hitta en väl definierad och inte alltför resurskrävande metod att samman-ställa statistik för avfallsmängden från byggsektorn i Sverige. Den framtagna statistiken ska kunna tjäna som en grund för rapporteringen till EU, men kanske främst för att olika aktörer i Sverige ska kunna följa upp sina miljömål. Arbetet har bestått av dels en genomgång av hur andra europeiska länder gör, dels intervjuer med olika aktörer i branschen. Viktiga delar har också varit diskussioner med en expertpanel vid början och slutet av projektet. Andra länder har använt enkäter, avfallsfaktorer, olika typer av administrativa system eller kombinationer av dessa för sina rapporteringar till EU. Tyvärr saknas uppgifter om osäkerhet i data med de olika metoderna. De olika aktörerna som har engagerats är byggföretag, avfallstransportörer och avfallsbehandla-re. Ingen av dessa grupper som helhet har idag färdiga system för samlad avfallsstatistik. Även om vissa företag inom de olika branscherna har kommit långt och har god kontroll på avfall från byggsektorn så är det inte heltäckande för branschen. Olika företag inom samma bransch an-vänder dessutom egna unika kodningssystem för olika typer av avfall. Idag finns därmed ingen renodlad naturlig väg att gå för att samla in avfallsstatistik från byggsektorn. Den naturliga vägen borde vara att gå via byggföretagen där avfallet primärt uppkommer, men idag finns inte tillräckliga system i branschen för detta ändamål och så länge som inga andra rättsliga krav ställs på byggföretagen så prioriteras inte heller detta område. Svårigheten med byggföretagen är dessutom att det finns över 70 000 registrerade företag i Sverige, och att de stora dominerande knappt 10 företagen troligen har en annan verksamhet än många av de små. Speciellt inom rivningsverksamhet med stora relativa avfallsmängder är de stora företagen un-derrepresenterade. Avfallsbehandlingsföretagen är färre, men risken är att man missar stora mängder fyllnadsmate-rial och redan sorterat material för återvinning som körs direkt till andra arbetsplatser eller rena återvinnare. Behandlingsföretagen bör dock vara de som har bäst möjligheter när det gäller att följa upp hur avfallet tas omhand efter sortering. För 2008 års rapportering använde SMED en grundlig kartläggning av en begränsad geografisk region, och sedan uppräkning till hela landet. Nackdelarna med den metoden är att den blir mycket beroende av en persons lokalkännedom, och att olika delar av landet antagligen har mycket olika byggprofil. För att få ett säkrare underlag skulle man behöva studera fler regioner.Då flera av de studerade länderna i EU har använt sig av avfallsfaktorer har användningen av avfallsfaktorer och byggd kvantitet också värderats. Det finns dock inte idag någon information eller färdiga faktorer som kan användas för att ge bra säkerhet över genererat avfall i byggbran-schen. En svaghet är hur faktorerna tas fram, och hur allmängiltiga de är. Särskilt är det svårt att få fram faktorer för renoveringar och rivningar. Det är också svårt att få fram bra siffror på genomförd verksamhet, särskilt inom anläggningssidan (vägar, broar, tunnlar osv.). Renodlade enkäter med en standardiserad blankett anses inte passa branschen med det stora antalet olika stora och små aktörer. Det slutliga valet har fallit på att detaljstudera ett antal avfallstransportörer i tre olika storleks-klasser, och att kartlägga deras transporter från byggföretag. Från dessa data räknar man upp till hela branschen. Viktigt för valet är att det är här som avfallet flyttas för första gången, och man undviker dubbelräkning och underskattning av större strömmar. Metoden innebär att ett urval av ett visst antal företag måste göras för att räkna upp till hela branschen. Det finns ett mindre antal väldigt stora avfallstransportörer och ett mycket stort antal små avfallstransportörer. Nackdelen med metoden är att det kan vara svårt att göra ett urval representativt för de mindre transportö-rerna, som sedan kan användas för uppräkning.

Safety culture and automated vehicles a pre-study
- 2022
-
Ingår i: Road Safety on Five Continents – RS5C. Proceedings. - Linköping. ; , s. 35-37
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Safety culture is the common attitudes, values and perceptions that managers and employees have about safety in the work environment. What characterizes a good safety culture is that management are committed to safety at all levels of the business. Management also rewards safe behavior and communicates safety priorities that engages all employees, which is evident from the behavior one can observe. The basic elements of safety culture according to the survey tool NOSAQ are:Priorities - know what to do or not to do, to set boundariesLeadership – commitment to safety and to reward itCommunication - clear and rich dialogueEngagement- including people in safety work at all levels in the companyWhen automation progresses, considerations of sustainability and gender equality should be considered with safety culture, to achieve the zero vision and the safe system approach. For professional drivers and controllers of autonomous vehicles the safety culture is of great importance in working and traffic environment. Companies that develop automated vehicles and machines need to acquire knowledge about how to integrate a good safety culture as part of the design and development processes as well as in the implementation of automated vehicles and machines. The aim of this pre-study was to explore safety culture in the development of automated vehicles and machines, to identify new risks and to prevent potential accidents. The scope of the pre-study 36 was to anchor the view of safety culture with industrial partners developing automated vehicles and machines. Through the exchange of knowledge, the need for a model of how to measure and work with safety culture as a factor in the development of automated vehicles, was defined.

Säkerhetskultur och självkörande fordon och maskiner
- 2024
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Självkörande fordon inom transportsektorn befinner sig ännu i utvecklingsstadiet. Att införa självkörande fordon och maskiner i befintliga verksamheter innebär ofta förändringar både i organisationen och den fysiska miljön och kan även innebära nya risker. I detta sammanhang kan säkerhetskulturen, både hos utvecklare och hos användare, spela viktig roll för att självkörande fordon och maskiner ska fungera säkert och effektivt i olika verksamheter. Projektets mål har varit att utveckla metoder för att förbättra säkerhetskultur där människor och automatiserad teknik samverkar som agenter i ett gemensamt system, samt att utveckla mätverktyg där hållbarhet, jämställdhet och säkerhet utvärderas för införande av självkörande fordon och maskiner. Projektet har utgått ifrån fallstudier från två olika domäner – självkörande bussar och självkörande industritruckar. Intervjuer har genomförts med utvecklare, kunder och slutanvändare. En enkät har tagits fram att mäta säkerhetskultur, jämställdhetskultur och hållbarhetskultur i organisationer som utvecklar självkörande fordon. Utöver detta har data från incidentrapporter analyserats. Lärdomarna från resultaten och projektdeltagarnas tidigare erfarenheter har resulterat i ett första utkast av en processmodell där säkerhetskultur integreras i utvecklingen av självkörande fordon och maskiner. Intervjuerna med utvecklare och kunder av självkörande fordon visade att säkerhetskultur inte var ett etablerat begrepp vare sig hos utvecklarna eller hos kunderna och att det därför inte var en faktor som man medvetet beaktade. Lärdomar från enkäten var att det finns skillnader mellan produktföretag och som markant påverkar formuleringar av frågeställningar. Det gick inte att fastställa om det föreligger kopplingar mellan hållbarhets-, jämställdhets- och säkerhetskultur. Fallstudien med bussarna visade bland annat att kund och leverantör pratar om olika typer av säkerhet samt att säkerheten ofta, men inte alltid, är prioriterad över effektiviteten. Utifrån analyserna av incidentdata från självkörande bussar samt förarlösa industritruckar har en lista med förslag på nyckeltal för att kunna analysera incidenter med självkörande fordon tagits fram inom projektet.

A scalable life cycle inventory of an automotive power electronic inverter unit—part I: design and composition
- 2019
-
Ingår i: International Journal of Life Cycle Assessment. - : Springer Science and Business Media LLC. - 1614-7502 .- 0948-3349. ; 24:1, s. 78-92
-
Tidskriftsartikel (refereegranskat)abstract
- Purpose: A scalable life cycle inventory (LCI) model, which provides mass composition and manufacturing data for a power electronic inverter unit intended for controlling electric vehicle propulsion motors, was developed. The purpose is to fill existing data gaps for life cycle assessment (LCA) of electric vehicles. The model comprises new and easy-to-use data with sufficient level of detail to enable proper component scaling and more in-depth analysis of inverter units. It represents a stand-alone three-phase inverter with insulated gate bipolar transistors (IGBTs), typical in electric vehicles. This article (part I) explains the modeling of the inverter design including the principles for scaling, exemplifies results, and evaluates the models’ mass estimations. Methods: Data for the design of power electronic inverter units was compiled from material content declarations, textbooks, technology benchmarking literature, experts in industry, and product descriptions. Detailed technical documentation for two electrically and electronically complete inverter units were used as a baseline and were supplemented with data for casings, connectors, and bus bars suitable for automotive applications. Data, theory, and design rules were combined to establish a complete model, which calculates the mass of all subparts from an input of nominal power and DC system voltage. The validity of the mass estimates was evaluated through comparison with data for real automotive inverter units. Results and discussion: The results of the LCI model exemplifies how the composition of the inverter unit varies within the model range of 20–200 kW and 250–700 V, from small passenger car applications up to distribution trucks or city buses. The models’ mass estimations deviate up to 14% from the specified mass for ten examples of real inverter units. Despite the many challenges of creating a generic model of a vehicle powertrain part, including expected variability in design, all results of the model validation fall within the targeted goal for accuracy. Conclusions: The LCI model combines different principles for the scaling of subparts into one model that capture important design implications of different power demands and voltage ratings. The model can be used for a generic estimation of the mass and material composition of a power electronic inverter unit controlling electric propulsion motors, for LCA, when specific data is lacking.

Determination of conformational flexibility of methyl α-cellobioside in solution by NMR spectroscopy and molecular simulations*
- 2004
-
Ingår i: Journal of Physical Chemistry A. - : American Chemical Society. - 1089-5639 .- 1520-5215. ; 108:18, s. 3932-3937
-
Tidskriftsartikel (refereegranskat)abstract
- The conformational flexibility of methyl α-cellobioside in water and dimethyl sulfoxide solutions was investigated by 1D 1H,1H T-ROESY experiments. In combination with molecular dynamics simulations, effective proton−proton distances could be derived using experimentally determined cross-relaxation rates. An anti-ψ-conformational state was present in both solvents confirming a previous flexibility hypothesis at this torsion angle. In water solution, an anti-φ-conformational state was also detected and quantified. These results show that already at the disaccharide level a large flexibility is present at the glycosidic linkage. In addition to the syn-conformation which is present to 93% for the title compound in water solution, the minor anti-φ- and anti-ψ-conformational states are populated to 2% and 5%, respectively.

Development of self-driving and control room functions and of external HMI for automated delivery vehicles
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Road users may need additional information to a vehicle’s speed and position in lane to understand the behavior and intentions of self-driving vehicles, such as external Human Machine Interface (eHMI), i.e. visual signals (lights) indicating the vehicle's status, behavior and intentions, especially in environments where self-driving vehicles are expected to drive at low speeds, for example, in urban environments. The study in this report developed and implemented self-driving functions and control room functions in an automated delivery vehicle (ADV), as well as developed an eHMI concept to communicate the vehicle’s states, intentions, and behaviour to the surroundings. The software stack and the development of the main features of the self-driving driving capabilities including the lateral controller are described in this report. Further, modules such as the Representational State Transfer (REST) for communication, the remote control of the ADV and the eHMI communication interface with the vehicle signals are presented. A lesson learned from the study is that further refinement in repeatability of the initial conditions of the system is essential. Most of the individual parts of the chain from a command to the ADV were created via the user interface in the Autonomous Transport Management System (ATMS). However, the whole chain was hard to achieve, and the need of frequent testing and integration was evident and faults in the chain could result in cumbersome and long procedures to restart the integration test. The study also revealed issues with the stability of the entire system. Several eHMI concepts have been developed in industry and in research. However, up to this date there are no standards or established frameworks for the design of eHMI. Nevertheless, guidelines and recommendations have been proposed in different studies, for example that eHMI should be consistent with existing eHMI, address road users in general and not tell or instruct other road users what to do. The eHMI-concept developed in this study conveyed the following messages: Automation mode, Acceleration, Deceleration and Delivery mode. A model for an eHMI-strategy is also proposed. The eHMI prototype on the ADV in this study was composed of LED lights with multiple color options, an ECU with CAN hardware and software that controlled the eHMI. The initial idea was to use vehicle data from the CAN bus, such as speed and steering angle and the control algorithm worked technically, but the eHMI for acceleration and deceleration were activated/inactivated too fast (within 1-2 seconds) for an observer to perceive and grasp the meaning of the eHMI. A lesson learned was that the activation/inactivation of the eHMI should, therefore, be executed by the computer that manages the autonomous driving functions in the ADV.

People’s understanding of external HMI and their experiences of interacting with an automated delivery vehicle in a terminal context
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This study investigated how the participants in a scenario of a terminal for goods handling perceived to interact with an automated delivery vehicle (ADV) for loading/unloading and how they understood the external Human Machine Interfaces (eHMI), i.e., visual signals on the ADV that communicate the ADV’s behaviour, mode and intentions. The objectives were (i) to test and validate the self-driving functions; (ii) to test and validate the control room functionalities and (iii) to evaluate how the participants understood the eHMI and (iv) to evaluate how they experienced to interact with the ADV in specific situations. The eHMI communicated four messages; Acceleration (from stand still), Deceleration (to stand still), Unplanned stop and Delivery mode. The participants were introduced to the scenario and instructed to act the role of being newly employed at a terminal for loading/unloading goods. There were two situations they were asked to handle: (i) the ADV had stopped (unplanned) due to an obstacle in front which had to be removed for the ADV to drive on, and (ii) to load/unload the ADV when it had stopped at a designated place for loading/unloading. The participants marked on a 5-point scale how easy/difficult it was to understand the different eHMI (eHMI communicated Acceleration from standstill, Deceleration to standstill, Unplanned stop and Load/Unload mode) and how safe/unsafe they felt to approach and interact with the ADV. The same procedures were repeated three times. The results showed that the participants thought it was easy to understand the different eHMI on the ADV, specifically the types of eHMI that are on vehicles today, such as hazard lights and turning indicators. The results also revealed that the context, i.e. terminal scenario, the situations, and the work tasks, was a contributing factor to their understanding of the eHMI. The participants’ previous and gained experiences also contributed to their understanding of the eHMI. The participants thought it was safe to approach the ADV, for example to remove the obstacle in front of the ADV, much because they assumed that such close interactions with the ADVs could happen often and, therefore, they assumed it was safe to interact closely to the ADV. The size of the ADV (smaller than a regular car) was also mentioned as a contributing factor. The self-driving functions in the ADV were integrated in the ADV’s system architecture. A challenge was to obtain stability in the system with repeated driving cycles. The Autonomous Transport Management System (ATMS) was put in a cloud service to enable remote testing, and to facilitate repeated integration tests as well as test-cycles with the ADV. The information in the messages sent to the ADV included, for example, the coordinates for the route and the control signals for the eHMI. In addition, a function was implemented to reset the ATMS easily when it entered a faulty state. The control of the LED lights for the eHMI was managed by the main Vehicle Control Unit (VCU) which provided more accurate output from the eHMI compared to using the vehicle data.

Product Representations Exploring Computer-Based Technologies and Customers' Understanding of Product Concepts
- 2001
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- A large proportion of new products does not succeed on the market. One explanation is that companies have misinterpreted, or not succeeded in identifying the needs and requirements of their customers. A focus on the customer, especially in the early stages in the product development, has been argued to improve product quality and customer satisfaction. A prerequisite of achieving knowledge about the customer is that developers and customers communicate on the basis of a shared understanding. For this purpose, product representations, e.g. sketches, mock-ups and virtual reality representations can function as communication tools. The demands for efficient product development have resulted in an interest in new computer-based technologies and arguments that virtual reality can replace costly physical prototypes. However, little is known about what customers understand of product concepts through different product representations. Thus, knowledge of product representations can be of importance to manage a product concept evaluation in an efficient way. This thesis has aimed at gaining knowledge for an efficient use of product representations in communication with customers. One question concerned the use of product representations in industry for communication with customers. The studies indicated that product representations were used between the developers for evaluations of technical matters and not used as tools in communication with customers. Moreover, virtual reality was widely considered as very effective for the understanding of product concepts, even though most companies had not used virtual reality in product development. Thus, the conception of virtual reality reflected high expectations rather than actual experiences. The main question in this research concerned computer-based technologies' and conventional product representations' effect on customers' understanding of product concepts. A series of exploratory studies revealed that an increasing degree of realism in the product representations was not always reflected in an increased understanding of the products. This implies that the information provided by a product representation was not necessarily the information required by the participants for enhanced understanding. Certain product aspects were more important than others for enhanced understanding, in this case, tactile interaction and scale. This thesis argues that customers' understanding of product concepts through product representations is determined by several interrelating factors and that the type of product representation is but one factor. Other important factors are the participants' product knowledge and the participants' product representation knowledge.

Typical and critical traffic situations with small electric delivery vehicles – indications for future Automated Delivery Vehicles
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This study investigated what typical traffic situations drivers of small manual delivery vehicles (MDV) are facing during their daily routes and how they handle these, sometimes critical, traffic situations. The purpose was to get an understanding of what challenges future automated delivery vehicles (ADV) may encounter and need to manage. Nine drivers of MDVs at one of Postnord’s terminals in Gothenburg, Sweden, were interviewed about their daily working tasks, their experiences of typical and critical situations and how they handle these situations. The interviews showed that many potentially critical situations were related the MDV’s relative slow speed (max 45 km/h). They could not always keep the same speed as other vehicles, which resulted in other vehicles driving closely behind the MDV and overtaking the MDV in narrow and busy roads. The interviews also revealed that the drivers often need to remove obstacles. Since an ADV cannot solve these kinds of problems like human drivers do the ADVs’ Operational Design Domain (ODD) may need to be adapted to the ADV’s capacity, e.g. being free of obstacles. The letters and packages are delivered to the addressees by the drivers. With ADVs, these “hand-over” operations need to be either taken care of by someone at the addressees or be replaced by a delivery system that does not involve the hand-over to the addressees. Another matter is that some general traffic rules are often vaguely formulated (“… adapt the speed to the bicycles…”, “…adjust the speed so there is no danger…”, “…to… in time…”) and leave much to the drivers to interpret their meanings and to act accordingly. How ADVs should comply with this kind of traffic rules could be a challenge. The drivers’ gained experiences seemed to be key to handle unforeseen events and to solve problems as they occur, for example through compensating behaviour, such as position in lane, acceleration/deceleration, steering manoeuvres etc. A “dynamic learning function” could be an important feature to implement in a future ADV-system. Overall, the interviews showed that the drivers are handling complex traffic situations and environments and that they need to manage many practical tasks to deliver the letters and packages to the addressees. Without human drivers a delivery system with ADVs would require a systems perspective throughout the whole logistics chain.

Use cases and high-level requirements for safe interactions between automated delivery vehicles and human operators in a terminal
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Small electric Autonomous Delivery Vehicles (ADV) can play an important role in future logistic chains under the last mile deliveries. In terminals where ADV are loaded with goods it is important that the interactions between the ADVS and the goods handling personnel is safe. Two workshops with developers of self-driving vehicles, researchers in the area of human-machine interaction and goods handling personnel form Postnord were conducted to identify challenges, needs and requirements regarding the design of ADV and the terminals för ADV. Due to COVID19, the workshops were carried out online and a video was shown to the participants demonstrating an ADV operating in a location representing a terminal. The two main objectives for this study were to gain understanding of the interactions between the ADV and human operators in the terminal and to identify high-level functional requirements for safe and efficient deployment of ADVs in terminals. The identified use cases related to (i) the ADV’s operations in the terminal, from entering to leaving the terminal and (ii) use cases where human operators interacted with the ADV, e.g. for loading/unloading goods. For each use case a high-level functional requirement was formulated. Human operators will most likely have important roles in delivery chains with ADV, such as loading and unloading of goods, as well as managing problems the ADV cannot solve. Consequently, how to design the human - ADV interactions will be critical from safety and efficiency points of view.

AI-baserad säkerhet på byggarbetsplatser
- 2023
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- AI-baserad säkerhet på byggarbetsplatser har varit ett ett-årigt projekt som genomförts för att förbättra säkerheten på anläggnings- och byggarbetsplatser genom användning av AI-teknologi. Projektet har varit ett samarbete mellan RISE Research Institutes of Sweden, NCC, Ramirent, Skanska och Viscando. Målet var att identifiera och analysera risker på arbetsplatserna med hjälp av sensorer och AI-modeller för att kunna förutsäga farliga situationer och utveckla lösningar för att förbättra säkerheten. Genom observationer, intervjuer och datainsamling med 3D-sensorer analyserades beteendemönster och riskområden på utvalda byggarbetsplatser. Resultaten användes sedan för att kommunicera och utveckla konkreta lösningar för att minska riskerna. Rapporten ger en översikt av metodologin, datainsamlings- och analysprocessen samt betonar vikten av att förstå både teknologins möjligheter och begränsningar för att skapa en säkrare arbetsmiljö på byggarbetsplatser.
