ABSTRACT:
The present invention is directed to a braking force control system capable of generating a first braking force and a second braking force that is a supplement to the first braking force. The first braking force is generated in response to the operation of the brake pedal. The second braking force is generated when the operation speed of the brake pedal is more than the threshold value. The operation stroke sensor detects the operation stroke of the brake pedal as the operation stroke data. The timer detects the operation time of the brake pedal as the operation time data. The operation speed of the brake pedal is calculated on the basis of the operation stroke data and the operation time data in the electric controller. The RAM of the electric controller memorizes operation stroke data and operation speed data from a plurality of operations. The threshold value is calculated on the basis of the plural operation stroke data and the plural operation speed data. In the electric controller the threshold value is then compared with the operation speed of the brake pedal.
