Abstract: The vehicle control system includes an abnormality diagnosis unit for determining whether a synchronization abnormality between a master ECU and a slave ECU has occurred. The abnormality diagnosis unit transmits and receives a signal between the master ECU and the slave ECU and acquires time information. The slave ECU calculates a delay time of transmission based on the acquired time information. Then, the abnormality diagnosis unit first determines whether or not there is a periodic shift. When determining that there is no periodic deviation, the abnormality diagnosis unit determines whether or not there is an offset deviation based on the difference obtained by subtracting the delay time from the second time and the first time. The abnormality diagnosis unit determines that a synchronization abnormality has occurred when it is determined that there is a periodic deviation or when it is determined that there is the offset deviation.

Abstract: A rotating machine and a pinion shaft are separately arranged on opposite sides to each other in the vehicle front-rear direction across a third axis that is an axis of a differential device in plan view as seen from above the vehicle. This configuration enables the rotating machine, a parallel shaft transmission, the pinion shaft, the differential device, and others to be integrally assembled to a case, to thereby configure an electric drive unit to be compact, which is advantageous in space.
