Publication number: 20240101093Abstract: A vehicle brake system includes a switching valve switchable between a first state allowing communication between a first fluid pressure generating device and a frictional brake and a second state allowing communication between a second fluid pressure generating device and the frictional brake. The second fluid pressure generating device generates a fluid pressure by moving a piston with an electric actuator, and has a fluid pressure supply port connected to the switching valve and an atmosphere opening port connected to a reservoir tank. When, due to a failure, the switching valve becomes a third state in which the switching valve makes each of the first fluid pressure generating device and the second fluid pressure generating device communicate with the frictional brake, a control device controls the second fluid pressure generating device to close the atmosphere opening port with the piston.Type: ApplicationFiled: September 20, 2023Publication date: March 28, 2024Inventors: Atsuki OHIRA, Eisuke HORII, Hiroyuki IWASAKI, Masayuki UENO, Shotaro YAMAZAKI, Takashi SHIMADA, Tomoaki KOTAKI, Yohei SATO

Publication number: 20240075915Abstract: A vehicle brake system includes a first fluid pressure generating device for generating a fluid pressure according to a brake operating amount, a second fluid pressure generating device for generating a fluid pressure by moving a piston with an electric actuator, and a switching valve switchable between a first state allowing communication between the first fluid pressure generating device and a vehicle behavior stabilizing device and a second state allowing communication between the second fluid pressure generating device and the vehicle behavior stabilizing device. A control device places the switching valve in the second state during execution of automatic brake control, and places the switching valve in the first state when a predetermined abnormality occurs in the vehicle, except that the control device places the switching valve in the second state when an abnormality including inability of the second fluid pressure generating device to generate the fluid pressure occurs.Type: ApplicationFiled: September 5, 2023Publication date: March 7, 2024Inventors: Eisuke HORII, Hiroyuki IWASAKI, Yohei SATO, Tomoaki KOTAKI, Masayuki UENO, Shotaro YAMAZAKI, Atsuki OHIRA

Patent number: 8960049Abstract: The purpose of the present invention is to provide a vehicle brake system having a high degree of mounting freedom. The present vehicle brake system is configured in such a manner that an input device into which braking operation of the operator is inputted and a motor cylinder device which generates hydraulic brake pressure on the basis of an electric signal according to at least the braking operation are disposed so as to be separated from each other in the engine room partitioned in front of the dashboard. The vehicle brake system is characterized in that the input device is disposed behind a power device in such a manner that at least a part of the input device overlaps the power device in the front-rear direction.Type: GrantFiled: November 10, 2011Date of Patent: February 24, 2015Assignee: Honda Motor Co., Ltd.Inventors: Kazuaki Murayama, Takaaki Ohnishi, Toru Mabuchi, Kaoru Akahane, Kazuyoshi Akutsu, Tomoaki Kotaki, Takehiro Horiuchi

Patent number: 8783404Abstract: A bracket (3) is installed in an engine room (12) of a vehicle (1) for supporting accessories (2). The bracket (3) includes: an upper anchoring portion (3a) and a lower anchoring portion (3b) each for anchoring the bracket (3) to the vehicle body (11); and a first supporting portion (3c) and a second supporting portion (3d) for securing the accessories (2) thereto, respectively. The lower anchoring portion (3b) is located below the upper anchoring portion (3a). The first supporting portion (3c) extends vertically between the upper anchoring portion (3a) and the lower anchoring portion (3b). The second supporting portion (3d) extends from the upper anchoring portion (3a) and is horizontally opposed to the first supporting portion (3c). The upper anchoring portion (3a), the lower anchoring portion (3b), the first supporting portion (3c), and the second supporting portion (3d) form an integrated body.Type: GrantFiled: January 26, 2011Date of Patent: July 22, 2014Assignee: Honda Motor Co., Ltd.Inventors: Tomoaki Kotaki, Atsushi Shioda
