为解决电传动车辆行驶过程中的动力分配问题,在车辆整体方案设计的基础上,对驾驶员操作指令进行合理的解析,并提出了一种基于“转速控制”方式的动力分配控制策略,通过对左、右侧驱动电机进行转速控制给定,实现车辆在各种复杂工况下的正常行驶,最后进行了系统建模和仿真。结果表明:基于该动力分配控制策略,车辆可实现稳定直驶、任意半径转向、中心转向以及电气制动等工况要求,并且具有良好的动力性能。
In order to solve the problem of power distribution during the driving process of electric drive vehicles, the driver’s operation instructions are reasonably analyzed on the basis of the overall vehicle design, and a power distribution control strategy based on “speed control” is proposed. , Through the left and right drive motor speed control given to achieve the normal operation of the vehicle in a variety of complex conditions, the final system modeling and simulation. The results show that, based on this power distribution control strategy, the vehicle can achieve stable driving conditions, arbitrary radius steering, center steering and electrical braking conditions, and has good dynamic performance.
