- Vehicle multiple-event accidents constitute 1/4-1/3 of all severe accidents. The present paper studies the control of the vehicle’s abnormal motion after being hit by another vehicle. The potential effectiveness of such a stability control system is estimated through accident data analysis and vehicle dynamics simulation. Only side impacts were simulated, but engineering judgments were made to project the effectiveness potential prediction on the total traffic work. Assuming ESC-like control (closed loop control on yaw rate, using wheel brakes) it is found that the function has potential to mitigate accident for up to 10-9 cars per driven km, or up to 0.1% of the cars in the accident database. While assuming Post Impact Stability Control by steering (closed loop control on yaw angle and path deviation, using steering), the corresponding figures are approximately ten times higher.

Enhanced yaw stability control to mitigate a vehicle's abnormal yaw motion due to a disturbance
- 2013
-
Patent (övrigt vetenskapligt/konstnärligt)abstract
- An enhanced stability control system (200) for a vehicle includes a vehicle status sensor that generates a sensor signal. A driver input sensor that generates an input signal. A controller (214) may disable normal yaw stability control operation and enable body-force-disturbance (BFD) yaw stability control (YSC) operation, which includes at least partially reducing response functions of the normal yaw stability control associated with the input signal, in response to the sensor signal and performing BFD-YSC functions to achieve desired control performance upon the detection of BFD reception. The controller (214) may also or alternatively compare the sensor signal to a threshold and detect an improperly functioning/inoperative vehicle status sensor. The controller (214) disregards information associated with the improperly functioning/inoperative vehicle status sensor, and continues to perform enhanced yaw stability control operations.
