To improve vehicle manufacturing efficiency by shortening the work time for managing ECU programs installed on a vehicle.SOLUTION: A vehicle control system includes a plurality of vehicle control units and a master control unit that is communicatively connected to the plurality of vehicle control units. Each vehicle control unit includes a non-volatile program storage unit that has a rewritable program storage area that stores a program for controlling a functional unit installed on a vehicle, and an information storage area that stores attribute information corresponding to an attribute of the vehicle control unit. The master control unit includes a nonvolatile master storage unit that stores write data for writing a program into the program storage unit. The write data includes vehicle control unit information for specifying a vehicle control unit for communication, and the attribute information of the vehicle control unit.SELECTED DRAWING: Figure 1
