A brake fluid pressure retaining apparatus RU is mounted on a vehicle equipped with an automatic transmission CVT and a driving motor control unit DCU. The driving motor control unit switches the magnitude of creep driving force between a greater condition and a smaller condition in accordance with a depression of the brakepedal, so that the driving force is made smaller at a depression of the brake pedal than at a release of the brake pedal. The brake fluid pressure retaining apparatus continuously retains brake fluid pressure within a wheel cylinder WC after releasing a brake pedal BP. The retained brake fluid pressure is released after the driving force increases to the greater condition and when a first setting time TM1 passes. When undesirable backward movement of the vehicle is detected by a backward movement state detection device BKD, the retained brake fluid pressure is released after a second setting time TM2, which decreasingly changes from a time longer than the first setting time in accordance with a throttle angle signal V_.theta.TH, passes instead of the first setting time.
