Abstract:
A clutch engagement condition determining apparatus for a vehicle, wherein drive wheels are driven by an engine by way of a multi-staged transmission, said transmission is actuated in association with the operation of a gear shift of said transmission, and while said transmission is in operation, said engine is disconnected from said transmission by means of a clutch whereas said drive wheels are driven by an electric motor, said clutch engagement condition determining apparatus comprising:vehicle speed parameter detecting means for detecting a vehicle speed parameter representing the speed status of said vehicle; gear shift operation detecting means for detecting whether of not the operation of said gear shift of said transmission has been executed; target vehicle speed parameter setting means for setting a target vehicle speed parameter based on a vehicle speed parameter detected by said vehicle speed parameter detecting means when the execution of said gear shift operation is detected by said gear shift operation detecting means; control signal value determining means for determining a control signal value which controls the revolution of said electric motor so that said detected vehicle speed parameter matches a target vehicle speed parameter set by said target vehicle speed parameter setting means while said drive wheels are driven by said electric motor; varying condition detecting means for detecting the varying condition of a control signal value determined by said control signal value detecting means; and engagement condition determining means for determining said engagement condition of said clutch according to the varying condition of a control signal value detected by said varying condition detecting means.
