Vehicle braking control device for braking force distribution
First Claim
1. A device for controlling a braking of a vehicle having front and rear wheels, comprising:
- a braking system generating braking forces on the respective wheels,at least one sensor monitoring an operational condition of the vehicle including a detector detecting an amount of a braking action by a driver of the vehicle, anda controller that is configured to execute an anti-skid control and that is configured to execute a braking force distribution control in which braking force on the front wheels is increased in comparison with braking force on the rear wheels when an operational condition monitored by a sensor among the at least one sensor satisfies a predetermined condition, wherein;
the braking force on the front wheels during execution of the braking force distribution control is increased, where a braking force increment on the front wheels is determined based upon an increment of the braking action by the driver detected by the detector;
however, when execution of the anti-skid control for either of the front wheels is started during the braking force distribution control, the braking force increment on the front wheels is decreased during the braking force distribution control, andthe decreasing of the braking force increment on the front wheels is interrupted if the anti-skid control is terminated but the increment does not reach zero.

Abstract
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. After the starting of BFD control, further increase in the braking action is reflected in the front wheel braking force. Upon starting anti-skid control for either of the wheels during the execution of BFD control, an increment of the front wheel braking forces to be requested by BFD control is gradually decreased. Simultaneously, the holding of the rear braking force is released 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.
