The invention discloses a vehicle motor over-temperature protection control method and device and a medium, and relates to the field of electric vehicle motor control, and the method comprises the steps: monitoring the actual temperature of a motor in real time through a motor controller, and obtaining the actual torque and the actual rotating speed of the motor; when the actual temperature reaches a first preset threshold value, comparing a first preset percentage value of the actual torque and the peak torque, the actual rotating speed and the rated rotating speed; when the actual torque is higher than a first preset percentage value and the actual rotating speed is lower than the rated rotating speed, the torque of a motor is reduced through a motor controller, the vehicle is monitored in real time, and whether the vehicle slips backwards or not is judged; and if not, linearly adjusting the power of the motor within a preset time according to a preset power adjustment standard until the power is adjusted to the continuous power. The temperature of the motor is monitored in real time, and corresponding measures are taken when the temperature exceeds the preset threshold value, so that the motor can be effectively prevented from being damaged due to overheating, and the operation safety of the motor is improved.

    本申请公开了一种车辆电机过温保护控制方法、设备及介质,涉及电车电机控制领域,方法包括:通过电机控制器实时监测电机的实际温度,并获取电机的实际扭矩和实际转速;当实际温度达到第一预设阈值时,将实际扭矩和峰值扭矩的第一预设百分值、实际转速和额定转速进行比较;当实际扭矩高于第一预设百分值且实际转速低于额定转速时,通过电机控制器降低电机的扭矩,并实时监测车辆,判断车辆是否出现后遛;若否,则根据预设功率调节标准,在预设时间内线性调整电机的功率,直至调整至持续功率。通过实时监测电机的温度,并在温度超过预设阈值时采取相应的措施,可以有效防止电机因过热而损坏,提高电机的运行安全性。
