Abstract:
The current electronic differential control strategy based on the Ackermann steering model only constrains the speed of the driving wheels and does not consider dynamic performance. This paper is based on wheel hub electric vehicles and focuses on the turning driving conditions of the vehicle. From the perspective of improving the stability of the vehicle's steering control, innovative electronic differential control methods based on sliding mode control and fuzzy control are designed. Taking the vehicle's lateral angular velocity and center of mass side slip angle as control objectives, the vehicle is driven at low speeds through double lane change. The control performance of the two designed electronic differentials is compared and verified with the electronic differential control strategy that evenly distributes the total driving torque. The results indicate that overall, sliding mode control has the best performance, maintaining excellent differential performance under various operating conditions. Based on fuzzy control, there is a certain degree of degradation in electronic differential performance during high-speed driving conditions. The electronic differential control system based on the average distribution of total expected torque can also achieve differential driving of vehicles, but its effect is not as good as the other two.
