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.
