Abstract:
1. A hybrid vehicle driving apparatus, comprising: an engine providing rotational driving power to driving wheels; a motor generator arranged between the engine and the driving wheels, the motor generator operating as an electric motor providing rotational driving power from the motor generator to the driving wheels and as a generator; a front clutch arranged between the engine and the motor generator, the front clutch that selectively switches the engine and the motor generator between a rotary engagement state and a disengaged state; an automatic transmission arranged between the motor generator and the driving wheels, the automatic transmission including an input shaft where the rotational driving power from the motor generator is provided as an input and an output shaft in rotary engagement with the driving wheels, the automatic transmission that selectively switches between a plurality of gear shift stages provided with different gear ratios from one another, the gear ratio, which is a value obtained by dividing number of rotations at the input shaft by number of rotations at the output shaft; a clutch control device that selectively engages the engine and the motor generator by sending out a first control signal to the front clutch to operate the front clutch; and an automatic transmission control device that selectively switches the gear shift stages between the plurality of gear shift stages by sending out a second control signal to the automatic transmission to control gear shift, wherein the clutch control device and the automatic transmission control device are connected to mutually communicate, wherein the clutch control device sends out a request to wait gear shift to the automatic transmission control device in a state where preparation for an operation of the front clutch is in progress, and wherein 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.
