The dynamic studies of dual-motor independent drive electric vehicle with network control

Abstract

Dual-motor independent drive electric real-time simulation. This paper establishes the vehicle have high requirements in the real-time vehicle models based on Matlab/Simulink. The and stability of communication systems. Based on the vehicle dynamic theory, Matlab/Simulink vehicle dynamic models are established, including vehicle dynamic model, driver model, in-vehicle network model and motor model .Then, analyze the influences of network transmission delay and sampling period on the vehicle dynamic response. The results show that, network transmission delay and sampling period can make the vehicle dynamic response deteriorate, improve the real-time of communication system can improve the vehicle steering and driving stabilities.
