The invention provides a motor controller for realizing ramp torque compensation, a control method and an electric vehicle. The motor controller is used for controlling a driving motor to output torque so as to drive wheels of the electric vehicle. In the process that the electric vehicle runs on the road surface with the gradient smaller than or equal to the preset gradient threshold value, the motor controller is specifically used for controlling the torque indicated by the torque signal output by one driving motor. When the electric vehicle runs on a ramp with the gradient larger than a preset gradient threshold value, the motor controller is specifically used for actively controlling one driving motor to adjust torque output. In other words, when the electric vehicle runs on the ramp, the motor controller can actively control the driving motor to adjust the torque output to achieve ramp torque compensation without being indicated by the whole vehicle controller, so that the vehicle speed of the electric vehicle when the electric vehicle passes through the ramp is maintained, and non-inductive ramp crossing is achieved.
本申请提供了一种实现坡道扭矩补偿的电机控制器、控制方法和电动车辆,该电机控制器用于控制一个驱动电机输出扭矩以驱动电动车辆的车轮。电动车辆在坡度小于或等于预设坡度阈值的路面行驶的过程中,电机控制器具体用于控制一个驱动电机输出扭矩信号所指示的扭矩。电动车辆在坡度大于预设坡度阈值的坡道行驶的过程中,电机控制器具体用于主动控制一个驱动电机调整扭矩输出。也就是说,电动车辆在坡道上行驶时,电机控制器可以无需整车控制器指示并主动控制驱动电机调整扭矩输出以实现坡道扭矩补偿,从而维持电动车辆在通过坡道时的车速,实现无感过坡。
