When the fuel supply to an internal combustion engine has stopped due to a vehicle starting to decelerate or the like, and the speed of the vehicle is greater than a predetermined speed, then a controller causes a power generator to operate in a first power generating mode. The controller charges a capacitor by using regenerative power that is output from the power generator to supply power from the power generator to the capacitor via a DC-DC converter. When the stopping of the fuel supply to the internal combustion engine is cancelled as a result of the engine revolution speed reaching a predetermined revolution speed (for example, an idling revolution speed) in conjunction with the speed of the vehicle dropping to the predetermined speed, the power generator can be kept in the first power generating mode.

Vehicle power supply device

A speed change control device carries out speed change control of a stepless speed change mechanism in accordance with the vehicle speed. The speed change control device includes: first vehicle speed selection means for comparing a first vehicle speed obtained from the rotation speed of an output memberof the stepless speed change mechanism and a second vehicle speed obtained from the rotation speed of the wheels and for selecting the lower of the first and second vehicle speeds as the substitute vehicle speed; and second vehicle speed selection means for comparing the third vehicle speed obtained from the output side rotation speed of a clutch mechanism and the substitute vehicle speed, and for selecting the higher of the third vehicle speed and the substitute vehicle speed as the control vehicle speed. The control vehicle speed is used as the vehicle speed V for carrying out speed change control.
