Abstract
A hybrid vehicle driving apparatus includes a clutch control device and an automatic transmission control device that are connected to mutually communicate. The clutch control device sends a request to wait gear shift to the automatic transmission control device while front clutch operation is in preparation. The automatic transmission control device that receives the request to wait gear shift determines whether priority is given to engaging or disengaging the front clutch or to shifting gears of the automatic transmission. The automatic transmission control device that is determined to give priority to the front clutch operation sends out a gear shift in stand-by state signal to the clutch control device while maintaining the automatic transmission in a gear shift prepared state. The clutch control device that receives the gear shift in progress signal restrains the front clutch from engaging or disengaging while maintaining the front clutch in an operation prepared state.
