基于转速控制的电传动车辆动力分配策略

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。

Power Distribution Strategy for Electric Drive Vehicle Based on Speed Control

In order to have a good power distribution of the electric drive vehicle in running,on the basis of the general design of the vehicle,this paper firstly analyzes the driver′s command,and then puts forward a control strategy based on speed control for power distribution so that the vehicle can steer normally under various complex conditions if given speed controls the left and right traction motors.Finally,the model of system is built and the control strategy is simulated.The result of simulation shows that,based on this kind of control strategy of power distribution,the vehicle can easily realize running straight,any radius steering,zero radius steering,electric braking and so on,and possess a good dynamic performance.
