Abstract:
A brake force control apparatus performing a brake assist control by adjusting a wheel cylinder pressure to a fluid pressure greater than a normal pressure when an emergency braking operation is performed by a driver, the brake force control apparatus comprising:emergency braking operation detecting means for preliminarily determining that an emergency braking operation is being performed when a detected operational speed of the brake exceeds a predetermined value;operational cause discriminating means for determining based on an increasing and decreasing frequency of a rate of change in an amount of a braking operation whether the preliminarily determined emergency braking operation is an intentionally performed actual emergency braking operation wherein, when the preliminarily determined emergency braking operation is not an actual emergency braking operation, the operational cause discriminating means determines that the preliminarily determined emergency braking operation is a result of an external disturbance; andbrake assist control prohibiting means for prohibiting execution of said brake assist control when the preliminarily determined emergency braking operation is the result of an external disturbance.
