A braking control device for a vehicle executes braking force distribution (BFD) biased to the front wheels, taking into account auxiliary braking control such as braking assist control (BAS) executed when an abrupt or full braking action is performed by the driver. In BFD control a braking force on the rear wheels is held at a holding braking force and a braking force on the front wheels is incremented beyond a braking force requested by a braking action of the driver. After the starting of BFD control, further increase in the braking action is reflected in the braking force of the front wheels. When 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.
A device for controlling braking force of a vehicle, the vehicle having front and rear wheels and braking force generating apparatuses provided for each of the wheels, the device executing a braking force distribution control operation that restricts an increase of a braking force on the rear wheels, generated by the braking force generating apparatuses of the rear wheels, to provide a braking force distribution among the front and rear wheels, biased to the front wheels, under a predetermined condition, wherein as the front wheel braking force increases during execution of the braking force distribution control operation, the device controls the braking force generating apparatuses of the front wheels to increment the front wheel braking force beyond the braking force increase by an amount based on a restricted amount of the braking force on the rear wheels.
A device for controlling a braking force of a vehicle, the vehicle having front and rear wheels, a braking system that generates braking forces on the respective wheels, and at least one sensor that monitors an operational condition of the vehicle, including a detector that detects an amount of a braking action by a driver of the vehicle, the device executing a braking force distribution control operation in which a braking force on the rear wheels is lowered in comparison with a braking force on the front 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 operation is increased, and wherein a braking force increment on the front wheels beyond the braking force increase corresponding to the braking action is determined based upon an increment of the braking action by the driver detected by the detector.
