The invention discloses a motor controller, a power assembly and a vehicle, the motor controller is applied to a driving motor, and the motor controller comprises a control device and an inverter circuit; the control device is used for receiving a brake signal of the vehicle, a rotating speed signal of the driving motor and a torque signal of the driving motor; the control device is further used for responding to the rotating speed indicated by the rotating speed signal to be larger than zero and smaller than the preset rotating speed, judging that the vehicle is close to the parking state and accordingly has the parking requirement, responding to the braking force indicated by the braking signal to be equal to zero and the torque indicated by the torque signal to be equal to zero and outputting a first control signal to avoid conflict with an operation mode intended by a driver. Wherein the first control signal is used for controlling the rotating speed of the motor to decrease to realize parking. The vehicle information is automatically judged in the motor controller, and the rotating speed of the motor is controlled, so that the control path is shorter, the response speed is higher, and rapid and accurate parking can be realized.

    本申请公开了一种电机控制器、动力总成及车辆,电机控制器应用于驱动电机,电机控制器包括控制装置和逆变电路;控制装置用于接收车辆的制动信号、驱动电机的转速信号和驱动电机的扭矩信号;控制装置还用于响应于转速信号指示的转速大于零且小于预设转速,判断出车辆接近停车状态,因此存在驻车需求,并响应于制动信号指示制动力等于零、扭矩信号指示的扭矩等于零,输出第一控制信号,避免与驾驶员意图的操作方式冲突,其中,第一控制信号用于控制电机转速下降实现驻车。由于本申请在电机控制器中自行判断车辆信息,对电机进行转速控制,因此控制路径更短,反应速度更快,从而可以实现迅速准确的驻车。
