CONTROL DEVICE OF VEHICLE WITH INTERNAL COMBUSTION ENGINE MOUNTED THEREON

摘要

PROBLEM TO BE SOLVED: To effectively execute the fuel cut and improve the fuel consumption by setting the release timing of a lockup clutch according to the load of the auxiliary machinery. SOLUTION: A drive system including a transmission is connected to an internal combustion engine via a mechanical clutch, and the internal combustion engine has a function device operated with the torque received from the internal combustion engine. The control device of the vehicle on which the internal combustion engine is mounted has load reducing means (Steps S3 and S6) for reducing the load of the function device on the internal combustion engine when the rotational frequency is the prescribed rotational frequency or higher, at the deceleration period when the mechanical clutch is engaged and when the rotational frequency of the internal combustion engine is lower than a prescribed rotational frequency.
