The invention provides a vehicle speed control method and a related device. The vehicle speed control method comprises the following steps: respectively acquiring a measured value at a first moment and a measured value at a second moment, wherein the measurement value is obtained by measuring the rotor position angle of the motor; determining the actual rotating speed of the motor based on the change rate of the measured value from the first moment to the second moment, wherein the change rate is the quotient of the change amount from the measured value at the first moment to the measured value at the second moment and the time difference between the second moment and the first moment; and inputting the actual rotating speed of the motor into a speed control module, and controlling the vehicle speed by the speed control module. According to the method, the rotating speed of the motor of the vehicle is directly determined through the obtained measurement value at the first moment and the obtained measurement value at the second moment, and the vehicle speed is accurately controlled according to the determined rotating speed of the motor.

    本申请提供了一种车辆速度的控制方法及相关装置;其中,所述车辆速度的控制方法,包括:分别获取第一时刻的测量值以及第二时刻的测量值;其中,所述测量值通过测量电机的转子位置角得到;基于所述测量值从所述第一时刻至所述第二时刻的变化率,确定电机的实际转速;其中,所述变化率为所述第一时刻的测量值至所述第二时刻的测量值的变化量,与所述第二时刻与所述第一时刻的时间差值的商;将所述电机的实际转速输入速度控制模块,由所述速度控制模块对车辆速度进行控制。从而实现了一种通过获取到的第一时刻的测量值以及第二时刻的测量值,直接确定车辆的电机的转速,并根据确定电机的转速对车辆速度进行精确控制的方法。
