Abstract
An integrated vehicle control system for integratedly controlling a vehicle drive system transmits a control command from a manager ECU to an engine ECU and an AT ECU. The manager ECU receives characteristic information of an engine and an AT from the engine ECU and the AT ECU. The control commands are set on the basis of the characteristic information. Further, the engine ECU and the AT ECU are provided with a plurality of control rules corresponding to different tuning patterns. The manager ECU retrieves realizable tuning patterns from these ECUs, and selects the optimum tuning pattern corresponding to a use of a vehicle.
