摘要:
With significantly different friction coefficients in the left and right wheels, the vehicle will be prone to out of control, such as wagging tail, when accelerating in straight-line. According to characteristics that the driving torque of four-wheel driving vehicle with electric wheels can be controlled independently, the driving torque control algorithm of inside and outside wheels was proposed based on PID control algorithm and DYC-TCS control strategy. It can get the optimal performance of the vehicle handling and stability. Four-wheel driving model has been built with software Adams/View, and was co-simulation with Simulink. The results show that during the straight-line acceleration tests with significantly different friction coefficient in the left and right wheels, the use of DYC-TCS control strategy is superior to traditional non-DYC-TCS control strategy, and better than only the TCS control program. With the DYC-TCS strategy, the maximum yaw-rate is 4% of the traditional non-DYC-TCS control strategy, the maximum lateral displacement is only 5%. © 2012 IEEE.
