The invention discloses a dual-motor controller, a control method and an electric vehicle, relates to the field of new energy automobiles, and can be applied to pure electric vehicles and hybrid vehicles. The dual-motor controller is used for restraining yawing of the electric vehicle in the running process on the split road surface, and the dual-motor controller is used for controlling the two driving motors to output torque so as to respectively drive two coaxial wheels of the electric vehicle. The dual-motor controller is specifically used for controlling the two driving motors to output torque indicated by torque signals at the first moment when the slip rates of the two wheels are both smaller than the preset slip rate. And at the second moment after the first moment, the slip rate of at least one of the two wheels is larger than the preset slip rate, and the two driving motors are actively controlled to reduce torque output at the same time. According to the scheme, the motor torque can be rapidly adjusted, the torques of the left wheel and the right wheel are equal, vehicle yawing is restrained, and the safety of the whole vehicle is improved.
一种双电机控制器,控制方法和电动车辆,涉及新能源汽车领域,可应用于纯电动车辆及混动车辆。该双电机控制器用于抑制电动车辆在对开路面行驶过程中的横摆,双电机控制器用于控制两个驱动电机输出扭矩以分别驱动电动车辆的同轴的两个车轮。双电机控制器具体用于在第一时刻,两个车轮的滑转率均小于预设滑转率,控制两个驱动电机输出扭矩信号所指示的扭矩。在第一时刻之后的第二时刻,两个车轮中的至少一个车轮的滑转率大于预设滑转率,主动控制两个驱动电机同时降低扭矩输出。根据本方案,可以快速调节电机扭矩,使左右两边车轮扭矩相等,从而实现抑制车辆横摆,提升整车安全性。
