VEHICLE INTEGRATED CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To sufficiently reduce the development time of an entire system and provide an optimum control performance at all times in a system integratedly controlling the operation of each controller by a host controller by installing the controllers for each component forming a vehicle. SOLUTION: In this system integratedly controlling a vehicle drive system by transmitting a control command from a manager ECU to an engine ECU and ATECU, the manager ECU receives the information on engine and AT(automatic transmission) characteristics sent from the engine ECU and ATECU (S190 to S220, S310 to S340) and, based on the characteristic information, sets a control command. Also, the engine ECU and ATECU comprise a plurality of control laws in correspondence with different tuning patterns, and the manager ECU acquires a tuning pattern realizable by these ECU, and selects the optimum tuning pattern in correspondence with the use of the vehicle (S130 to S180, S250 to S300).
