N2 - Relevant studies show that vehicle instability such as drifting and spinning after the first impact may have further severe implications in road vehicle collision accidents. This paper presents a post-impact stability control scheme for four-wheel-independently-actuated electric vehicles (FWIA EVs). First, a sliding mode controller is designed to produce the reference yaw moment to attenuate undesired yaw motion after the first impact. Then, an optimization-based algorithm is developed for optimal wheel torque allocation and steering angle coordination to follow the derived reference yaw moment. Finally, the holistic algorithm is verified through co-simulation of Matlab/Simulink and CarSim. The verification results show that the developed scheme performs well and can maintain the stability of the test vehicle after a maximum lateral-rear impact impulse of 3500 Ns.
