Patent number: 7488047Abstract: During normal operation in which a motor cylinder is operative, when a depressing force cut-off valve is closed, a front wheel is braked by operating a first wheel cylinder by brake fluid pressure generated by the motor cylinder. When there is an abnormality in which the motor cylinder breaks down, the front wheel is braked by supplying, via the opened depressing force cut-off valve, brake fluid pressure generated by a master cylinder operated by a driver's braking operation to the first wheel cylinder, and a rear wheel is braked by supplying the brake fluid pressure to a second wheel cylinder. Thus, since both the front and rear wheels are braked by the brake fluid pressure generated by the master cylinder in case of abnormality, a vehicle can be reliably stopped by a sufficient braking force.Type: GrantFiled: October 17, 2005Date of Patent: February 10, 2009Assignee: Honda Motor Co., Ltd.Inventors: Kunimichi Hatano, Hiromi Inagaki, Osamu Yamamoto, Takehiro Horiuchi, Nobuyuki Ishii

Publication number: 20060091726Abstract: During normal operation in which an electric braking device is operative, when a depressing force cut-off valve is closed and communication between a master cylinder and a disk brake system of a front wheel is cut off, the front wheel is braked by a brake pad directly driven by drive force of the electric braking device. When there is an abnormality in which the electric braking device breaks down, a wheel cylinder of a drum brake system of a rear wheel is operated by brake fluid pressure generated by the master cylinder operated by a driver's braking operation. Thus, since the drum brake system having a high braking function is operated in case of abnormality, the braking force is higher than the braking force during normal operation, thereby reliably stopping the vehicle.Type: ApplicationFiled: October 17, 2005Publication date: May 4, 2006Applicant: Honda Motor Co., Ltd.Inventors: Kunimichi Hatano, Hiromi Inagaki, Osamu Yamamoto, Takehiro Horiuchi, Kiyotaka Minoura

Publication number: 20050077782Abstract: An electrically driven parking brake device includes a ratchet mechanism for restricting movement in a brake releasing direction of a piston which is operated by an electrically driven motor to generate a braking force. In the ratchet mechanism, a ratchet wheel is temporarily rotated in a braking direction to disengage a ratchet pole from the ratchet wheel, thereby releasing the braking force. Even when the electrically driven motor fails to be unable to release the braking force, a manually operated bolt presses the ratchet pole to disengage the ratchet pole from the ratchet wheel, thereby releasing the braking force. Thus, the situation where the vehicle cannot move can be avoided, even when the electrically driven parking brake device is held in operation due to motor failure or the like.Type: ApplicationFiled: September 15, 2004Publication date: April 14, 2005Applicant: Honda Motor Co., Ltd.Inventors: Takehiro Horiuchi, Osamu Yamamoto, Kiyotaka Minoura, Kunimichi Hatano

Publication number: 20040256911Abstract: A braking device for a four-wheel vehicle includes a first front wheel brake pair including a hydraulic brake and an electric brake, to brake one front wheel; a second front wheel brake pair including a hydraulic brake and an electric brake, to brake the other front wheel; a first rear wheel electric brake to brake one rear wheel; and a second rear wheel electric brake to brake the other rear wheel. Thus, the braking device can use the hydraulic brakes and the electric brakes by rationally combining them, while eliminating need for a booster and avoiding increase in the size of a hydraulic pressure source and in the voltage of a power source.Type: ApplicationFiled: May 3, 2004Publication date: December 23, 2004Applicant: Honda Motor Co., Ltd.Inventors: Kunimichi Hatano, Takehiro Horiuchi, Kiyotaka Minoura, Osamu Yamamoto
