摘要： 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 brake pedal, 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_&thgr;TH, passes instead of the first setting time.

摘要： Surplus pressure is obtained from a difference between a hydraulic pressure value detected by a hydraulic pressure sensor and a target supplied hydraulic pressure. A determination is made about whether or not a possible hydraulic pressure in a prescribed time will become lower than a minimum required hydraulic pressure based on a current surplus pressure and a changing rate of the surplus pressure. If the possible hydraulic pressure is lower than the minimum required hydraulic pressure, correction is conducted to increase supplied hydraulic pressure. Accordingly, control is conducted so that the regularly required surplus pressure can be reduced to a minimum required amount.

摘要： The present disclosure presents a wheel diameter variation-detecting device capable of properly detecting relative variation in diameter between a plurality of wheels of a vehicle. The wheel diameter variation-detecting device can detect variation in diameter between a plurality of wheels of a vehicle, can detect rotational speeds of the respective wheels, and can calculate a variation parameter indicative of variation in diameter between the wheels using one of the wheels as a reference wheel, based on a result of comparison between the rotational speed of the reference wheel and that of one of the wheels other than the reference wheel. Further, the wheel diameter variation-detecting device can learn the variation parameter based on a value obtained by averaging a plurality of values of the variation parameter obtained before the detected travelled distance reaches a predetermined distance.
