The invention relates to a motor rotating speed transmission system and method for a vehicle. According to the motor rotating speed transmission system for the vehicle, the vehicle includes a hub motor, the motor rotating speed transmission system includes a vehicle control unit, a motor control unit used for calculating the motor rotating speed of a hub motor, a bus, and a serial port cable. The vehicle control unit is configured to transmit first data including first time to the motor control unit through the serial port cable. The motor control unit is configured to calculate a current motor rotating speed after receiving the first data from the vehicle control unit, and send second data including second time and the calculated motor rotating speed to the vehicle control unit through the bus, wherein the second time is obtained by adding the first time and the motor rotating speed calculation time of the motor control unit.

    本发明涉及车辆的电机转速传输系统和方法。公开了一种车辆的电机转速传输系统,该车辆包括轮毂电机,电机转速传输系统包括:车辆控制单元;电机控制单元,用于计算轮毂电机的电机转速;总线;和串口缆线。车辆控制单元构造成通过串口缆线向电机控制单元发送包括第一时间的第一数据。电机控制单元构造成在接收到来自车辆控制单元的第一数据后计算当前的电机转速,并且通过总线向车辆控制单元发送包括第二时间和计算的电机转速的第二数据,其中第二时间是由第一时间加上电机控制单元的电机转速计算时间得到。
