后轮独立驱动FSEC控制策略的研究与仿真

Research and Simulation of FSEC Vehicle Control Strategy with Rear Wheel Independent Drive

近期由于电动汽车的飞速发展,电动方程式赛车也得到了相关发展。但是国内关于电动方程式赛车的整车控制策略研究较少,而整车控制器(VCU)又十分重要,通过能量回收、电子稳定性、电子差速、牵引力控制控制策略相结合对整车控制策略进行研究。并通过Matlab与Carsim的联合仿真验证,其仿真结果表明:能量回收效果可观、电子稳定性控制策略通过对电子差速的修正有效防止转向过度、牵引力控制策略有效改善驱动防滑。其结果证明此整车控制策略算法简单,控制结果符合比赛要求。

Recently, owing to the rapid development of electric vehicles, the electric formula car has been developed relatively. Although vehicle control unit(VCU) plays an important role,t here are few researches on the vehicle control strategy for electric formula car in China. This paper focus on the vehicle control strategy which combines the energy recovery, electronic stability, electronic differential speed and traction control strategy. The simulation was carried out using the MATLAB and CarSim joint simulation and the results show that energy recovery effect is considerable, the electronic stability control strategy can prevent over steering obviously, and the traction control strategy can improve the drive antiskid efficiently. The results show that the algorithm of vehicle control strategy is simple and the control results can meet the requirements of the competition.
