Abstract:
1. A device for controlling a braking force of a vehicle, the device comprising: a braking force boosting control portion that increases the braking force in response to a detection of a possibility of a collision with an obstacle in a driving course of the vehicle; and a boost-reducing control portion that controls the boosting control portion so as to reduce the braking force when a steering operation is executed by a driver of the vehicle as compared to a braking force to be generated when no steering operation is executed, thereby reducing the braking force and allowing the driver to avoid a collision through the steering operation executed by the driver, wherein the boost-reducing control portion controls a reduction in the braking force based upon a lateral force on a steered wheel estimated from the steering operation by the driver and a motional condition of the vehicle, wherein the boost-reducing control portion controls the boosting control portion so that the braking force on a steered wheel is smaller than that on a non-steered wheel.
