    摘要： A braking control device for a vehicle executes braking force distribution (BFD) biased to front wheel in a manner compatible with Anti-skid control. In BFD control, braking force on rear wheels is held at a holding braking force and braking force on the front wheels is incremented beyond braking force requested by a braking action of a driver (S120). After the starting of BFD control, further increase in the braking action is reflected in the front wheel braking force. Upon detecting a terminating condition for BFD (S90) or upon starting anti-skid control for either of the wheels during the execution of BFD control (S140), an increment of the front wheel braking forces (ΔPf) to be requested by BFD control is gradually decreased (S160). Simultaneously, the holding of the rear braking force is released (S190) so as to compensate for the shortage of braking force on the front wheel. The gradual decrease of the braking force increment prevents a conflict of BFD and Anti-skid control.

    摘要： A braking control device of a vehicle starts executing braking force distribution (BFD) biased to front wheels for avoiding the locking of rear wheels prior to the front wheel at appropriate time by reducing errors of a judgment of the starting of the control. Usually, the BFD control is started in response to the increase of a master cylinder pressure, assuming that the rear wheel braking pressure is equally increased. When a fast braking action occurs, the delay of the pressure variation of the rear wheel braking pressure relative to the master cylinder is conspicuous because the responsibility of a master cylinder pressure to the braking action is too fast. Thus, Upon a fast braking action, a judgment of starting of BFD control is made based upon a value involved with rear wheel braking force, such as an estimation value of the rear wheel braking pressure, having a slower responsibility to the braking action than the master cylinder pressure, and thereby preventing a premature start of the BFD control due to the delay of the rear wheel braking pressure. When a deceleration signal is used for the judgment of starting of BFD control, the signal is passed through a low-pass filter having a rather higher cut-off frequency on a fast braking action, in order to improve the responsibility of the signal to the braking action.

    摘要： A braking control device for a vehicle executes braking force distribution (BFD) biased to front wheel, taking into account auxiliary braking control such as Braking assist control to be executed when an abrupt or full braking action is done by the driver. In BFD control, braking force on rear wheels is held at a holding braking force and braking force on the front wheels is incremented beyond braking force requested by a braking action of a driver. After the starting of BFD control, further increase in the braking action is reflected in the front wheel braking force. When the auxiliary braking control is executed, the holding braking force on the rear wheels and the increment of the braking force on the front wheels are determined based upon a demand of the auxiliary braking action as well as the braking action amount by the driver.
