Patent ID: 8308610

Claim:
A device for controlling a power transmission device of a vehicle, comprising a clutch between an engine and a transmission mounted on the vehicle, said clutch being equipped with a clutch control device which disengages said clutch at a time of a gearshift, wherein said vehicle comprises a wheel rotational speed detector for detecting directly an actual speed of the vehicle, wherein said transmission comprises a shift control device which outputs a shift instruction signal, wherein said shift control device comprises a target value-setting means which sets a target engine rotational speed at the time of the gearshift, the target engine rotational speed being set depending on the actual speed of the vehicle detected by the wheel rotational speed detector in a case of a shift-up, wherein said engine comprises an engine control device that executes an accelerator follow-up control in which the engine is controlled relying upon an accelerator pedal depression as a basic parameter, and wherein, at the time of the gearshift, said engine control device switches to a gearshift engine control in which the engine is controlled to rotate at the target rotational speed set by the target value-setting means.
