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.
