Differential Strategy Research for Vehicle with Motorized Wheels Based on Torque Control

摘要

According to the electronic differential problems for vehicle with motorized wheels, the electronic differential control strategy based on torque control is designed through BP neural network theory, and a suitable BP network is trained with the help of Matlab toolbox. The consistency of both sides on wheel slip ratio is achieved through the differential controller. The controller contains two models. One is BP neural network model which calculates demand regulating by longitudinal speed and steering wheel angle. The other is electronic throttle distribution model which calculates the target opening degree of electronic throttle on two sides by torque regulating variable. The validity of control strategy is confirmed by simulation results, which show that the differential problem is well solved by the control strategy.
