A power control device for a power supply mounted on a vehicle is provided, which includes a generator mounted on the vehicle and configured to regenerate power from kinetic energy of the vehicle, a high-voltage battery configured to accumulate the power regenerated by the generator, a low-voltage battery of which a nominal voltage is lower than the high-voltage battery, a voltage converter configured to lower an output voltage from the high-voltage battery and charge the low-voltage battery at the lower voltage, and a controller configured to control the voltage converter. The controller operates the voltage converter to start the charging of the low-voltage battery after the vehicle is powered ON and before an engine mounted on the vehicle is started.

Power control device for vehicle

A control device for a multi-stage automatic transmission-equipped vehicle includes a hydraulic power controller, a combustion controller configured to, if a predetermined combustion stop condition is satisfied when the vehicle is traveling, perform deceleration-period combustion stop control, and limit combustion restart triggered by a reduction in rotational speed of an internal combustion engine, during execution of the deceleration-period combustion stop control, and a motoring controller configured to control the rotational drive of the internal combustion engine by a motor during execution of the deceleration-period combustion stop control so that the rotational speed of the internal combustion engine is maintained at a predetermined rotational speed during a period of time from the time that the rotational speed of the internal combustion engine decreases to the predetermined rotational speed until downshifting to a predetermined gear ratio is completed.
