Abstract
A hybrid vehicle is driven by an engine and/or motor by tightening and releasing a clutch interposed between the engine and a transmission. A selector lever position is detected, and a clutch current is interrupted when the selector lever is not in a range for forward motion. In this way, the clutch current is forcibly interrupted when the vehicle is not moving forward, so tightening of the clutch is definitively prevented even if a clutch current control CPU operates incorrectly.
