Patent ID: 8251461

Claim:
A brake control device for a two-wheeled motor vehicle comprising: at least two front wheel cylinders that generate fluid pressure for applying brake force to a front wheel; at least two rear wheel cylinders that generate fluid pressure for applying brake force to a rear wheel; a front wheel brake conduit that is coupled between a front wheel master cylinder and one of the front wheel cylinders; a rear wheel brake conduit that is coupled between a rear wheel master cylinder and one of the rear wheel cylinders; a front wheel pressure amplification conduit that branches from a first position in the front wheel brake conduit and merges with the front wheel brake conduit at a second position downstream of the first position; a front wheel combined brake conduit that branches from a third position in the front wheel brake conduit positioned downstream of the first position and is coupled to the other of the rear wheel cylinders; a first front wheel switch control valve that is disposed between the first position and the third position in the front wheel brake conduit; a second front wheel switch control valve that is disposed in the front wheel pressure amplification conduit; a front wheel hydraulic pump that is disposed in the front wheel pressure amplification conduit; a rear wheel pressure amplification conduit that branches from a first position in the rear wheel brake conduit and merges with the rear wheel brake conduit at a second position downstream of the first position; a rear wheel combined brake conduit that branches from a third position in the rear wheel brake conduit positioned downstream of the first position and is coupled to the other of the front wheel cylinders; a first rear wheel switch control valve that is disposed between the first position and the third position in the rear wheel brake conduit; a second rear wheel switch control valve that is disposed in the rear wheel pressure amplification conduit; a rear wheel hydraulic pump that is disposed in the rear wheel pressure amplification conduit; and a control device that controls the opening and closing of the valves disposed in the brake control device and actuation of the front wheel and rear wheel hydraulic pumps.
