Patent number: 8315773Abstract: A brake force maintain control device for a vehicle determines whether the vehicle is in a rapidly-pressed state. The rapidly-pressed state is a state in which the brake pedal of the vehicle has been further pressed rapidly. While the vehicle is in the rapidly-pressed state, the brake force maintain control device allows the brake force maintain control to start if a condition for starting the brake force maintain control is satisfied. Therefore, it is possible to prevent the brake force maintain control from being needlessly executed even though the driver does not have an intention of executing it.Type: GrantFiled: July 17, 2009Date of Patent: November 20, 2012Assignee: Advics Co., Ltd.Inventors: Toshimi Ishikawa, Satoshi Naganawa
