Study on Energy-Saving Driving Mode during Cornering for Motorized Wheels Driving Vehicle

Abstract:

In order to study the energy consumption feature when cornering for motorized wheels driving vehicles, the resistance force on the driving axle was analyzed. A creative method quasi-neutral steering was proposed for vehicle cornering. A motorized wheels driving vehicle model was established, and the simulation of constant speed cornering was performed when the yaw rate as the parameter to control the front-rear torque distribution and the lateral acceleration as the parameter to control the left-right torque distribution. The results indicate that no wheel slipping is happened when quasi-neutral steering. The torque on the rear outer wheel is more than other wheels, and the torque on the outer wheels is more than inner wheels. The power consumption decreases 1.15% by quasi-neutral steering.
