Abstract
A vehicle control apparatus has a control unit for controlling an engine based on an engine control program and a control unit for controlling a transmission based on a transmission control program. The control units share a predetermined control data such as an engine rotation speed as a shared data. Forwarding a data from the control unit which provides the shared data to the control unit which receives the shared data is effected through shared memories provided separately from storage areas in which all the control data to be used by the control units in respective control operations are stored. Even if the system has different configurations, the addresses to be accessed for sharing the control data between the control units are the same so that the same control programs can be used.
