Abstract

A common control unit in an intra box performs common control that is independent from behavior control for controlled objects extracted from function domain controllers. A control condition management unit manages control conditions that are commonly used by the function domain controllers for performing the behavior control. An inspection unit inspects abnormality of the behavior control by the function domain controllers. A resource management unit manages distribution as well as residue amount, storage, and use restriction of commonly owned resource. A plug and play management unit manages system configuration of a vehicle control system. By using the above units, the vehicle control system reduces processing load of function domain controllers for performing the behavior control in respective function domains as well as adaptation operation of the function domain controllers to the system configuration.
