Abstract

In order to study the energy consumption feature of motorized wheels driving vehicle during steering, the resistance force was analyzed when the vehicle ran on curvy road, and a energy-saving mode of quasi-neutral steering was proposed. A simulation model of the vehicle was established by using MATLAB/Simulink, the yaw rate was taken as the control variable to control the front-rear torque distribution coefficient with PID, the lateral acceleration was taken as the control variable to control the left-right torque distribution coefficient with PID, and the steering condition at constant speed was simulated. Simulation result indicates that in the mode, no wheel slipping happens, the torque of rear-outer wheel is maximal, the torque of outer wheel is larger than the torque of inner wheel, the torque of rear wheel is larger than the torque of front wheel, and the power consumption decreases by 1.15%.
