Abstract
A vehicle control device includes an engine, a starter for starting the engine, a transmission for transmitting power of the engine to a driving wheel, an oil pump for supplying hydraulic pressure to the transmission according to the power of the engine, an accumulator for accumulating the hydraulic pressure ejected from the oil pump, and an electromagnetic on-off valve for controlling the hydraulic pressure accumulated in the accumulator. When the engine is restarted after the engine has stopped, an ECU of the vehicle control device opens the electromagnetic on-off valve at the time a line pressure has become equal to or higher than a predetermined hydraulic pressure after the start of the starter, and supplies the hydraulic pressure accumulated in the accumulator to respective portions of the transmission.
