Abstract
A vehicle control system includes a plurality of in-vehicle devices. Each of the in-vehicle devices includes a compatibility information storing unit that stores compatibility information including an allowable combination of software versions of all the in-vehicle devices constituting the vehicle control system. A particular in-vehicle device as one of the in-vehicle devices includes an obtaining unit that obtains software versions of the other in-vehicle devices, and compatibility information held by the other in-vehicle devices, a compatibility information specifying unit that specifies proper compatibility information, from the compatibility information stored in the particular in-vehicle device, and the compatibility information obtained from the other in-vehicle devices, and a determining unit that determines whether the software versions of all the in-vehicle devices constituting the vehicle control system are compatible, by checking the software version of the particular in-vehicle device, and those obtained from the other in-vehicle devices, against the proper compatibility information.
