The invention relates to a hydraulic pressure control apparatus for a vehicle with an automatic transmission, so as to improve the restarting response of the vehicle with the automatic transmission which effectively makes use of the idling stop of an accumulator. A hydraulic pressure loop of the automatic transmission is connected with the accumulator via an electromagnetic cut valve.
