摘要:

为了提高两后轮独立驱动电动汽车的操纵稳定性,提出一种驱动力分层控制策略.该分层控制策略包括车辆动力学模型设计层、补偿横摆力矩制定层和驱动力分配层,将车辆横摆角速度和质心侧偏角的实际值与理想值的偏差作为控制量,利用模糊算法计算得出两侧车轮的驱动力矩.在前期仿真验证的基础上进行实车快速控制原型试验,验证控制策略的实车控制效果.试验结果表明,设计的驱动力分层控制策略在过弯时能够对驱动轮转矩进行合理分配,在不影响车辆动力性的同时,提高车辆的操纵稳定性.

Abstract:

A driving force hierarchical control strategy was proposed in order to improve the stability of rear-wheel-independent-drive electric vehicle. This control strategy  induded three parts: vehicle dynamic model design layer, compensated yaw moment determining layer and driving force distribution layer. The error of actual value and ideal value of yaw rate and sideslip angle was inputted and the driving force was counted through a fuzzy logic. A rapid control prototype test was  conducted  to prove the effectiveness of this control strategy. Results show that this control strategy can improve the steering stability of vehicle through reasonably distributing the driving torque to driving wheel which also ensures the power performance of the electric vehicle.
