Abstract
A vehicle clutch engagement condition determining apparatus determines the engagement condition of a clutch for disengaging an engine from a transmission. This determining apparatus estimates a motor speed corresponding value through an ECU, sets the motor speed corresponding value to the target speed of an electric motor when a gear shift lever of the transmission is operated, determines a control current value for controlling the speed of the electric motor so that the speed of the electric motor detected matches the target speed while drive wheels are driven by the electric motor and determines the engagement condition of the clutch based on an electric current deviation.
