| Abstract: | The application prospect of electric limited slip differential (ELSD) in vehicles and its effect on improving vehicle dynamic characteristics and safety are addressed. The new control method for ELSD combines both feed forward and feedback compensations to control the dynamic behavior of the vehicle, in which the factor of feedback compensation is determined by optimal control. The results of simulation prove that the ELSD can markedly improve the handling stability and active safety of the vehicle under all road conditions. |
