Abstract

This paper presents a control strategy of torque distribution for electric vehicles with axles separately driven. With two motors driving the front and rear axle separately, the torque distribution between axles can be easily achieved. To obtain good traction performance and stability of the electric vehicle, three control modes appropriate for different driving conditions are adopted: the routine control of equal distribution, the distribution based on Sliding Mode Control (SMC) to minimize wheel slip difference between axles, axles separately antiskid control based on SMC. With MATLAB/SimDriveline software, a forward vehicle simulation model was set up. The simulation results show that the torque distribution control strategy of three control modes can maintain the wheel slip in a reasonable range regardless of driving conditions, improving both vehicle traction ability and stability.
