| 摘要： | Acceleration slip regulation control system is a new active safety technology.In this paper,through the research of the four-wheel independent drive electric vehicle,a sliding mode variable structure control arithmetic based on the exponent approach law is proposed,which is applied to the ASR system after the analysis of the vehicle acceleration procedure.First,This paper analyzes the quarter vehicle simulation model and the tire modle.Afterwards,establish a seven DOFs vehicle dynamics model,then tests the effect of the ASR control strategy of the car driving on the poor condition road.The simulation data shows that the vehicle acceleration performance improvement rate increases by 43.5%and 58.5%with the control strategy,during the two simulation process.This result indicates that the sliding mode variable structure control arithmetic applied to ASR system has a good adaptation to good and slippery roads.The algorithm can greatly improve the four-wheel independent drive electric vehicle's acceleration performance. |
