Patent number: 7878605Abstract: A brake apparatus for a vehicle generally sets an upper limit value of regenerative braking force to the maximum value of the regenerative braking force which can be generated at the present. In the case of a front-wheel-drive vehicle, the total braking force, the sum of front-wheel braking force (front-wheel hydraulic braking force+regenerative braking force) and rear-wheel braking force (rear-wheel hydraulic braking force), is rendered coincident with a target braking force corresponding to a brake pedal depressing force, and the regenerative braking force is set to a largest possible value equal to or less than the upper limit value. As a result, the regenerative braking force can be larger than front-wheel-side target distribution braking force. The upper limit value is decreased from the maximum value by an amount corresponding to the degree of easiness of occurrence of a locking tendency at the driven wheels (front wheels).Type: GrantFiled: July 12, 2006Date of Patent: February 1, 2011Assignee: Advics Co., Ltd.Inventors: Koichi Kokubo, Masahiro Matsuura, Shigeru Saito, Yuji Sengoku

Patent number: 7761214Abstract: A vehicle deceleration control device is provided that can determine an appropriate supplemental braking force when a braking force is applied according to an accelerator operation state. An engine braking-equivalent braking force is varied according to an initial accelerator angle when an accelerator returns and according to an accelerator return speed. That is, the greater the initial accelerator angle is, or the greater the accelerator return speed is, the greater the value to which the engine braking-equivalent braking force is set. It therefore becomes possible to determine the appropriate supplemental braking force that reflects the driver's braking intention.Type: GrantFiled: November 7, 2006Date of Patent: July 20, 2010Assignee: Advics Co., Ltd.Inventors: Shigeru Saito, Koichi Kokubo, Masahiro Matsuura, Yuji Sengoku

Patent number: 7575287Abstract: An improved vehicle brake system for controlling the frictional braking force and the regenerative braking force to be applied to a wheel of a vehicle. The brake system reduces the regenerative braking force to a predetermined force and keeps the regenerative braking force at the predetermined force before the start of anti-lock control. When the anti-lock control starts, the brake system decreases the regenerative braking force from the predetermined force. With this arrangement, it is possible to quickly eliminate a locking tendency of any wheel of the vehicle, thereby stabilizing the vehicle.Type: GrantFiled: August 22, 2006Date of Patent: August 18, 2009Assignee: Advics Co., Ltd.Inventors: Masahiro Matsuura, Koichi Kokubo, Shigeru Saito, Yuji Sengoku

Patent number: 7571967Abstract: A brake apparatus for a vehicle controls braking force acting on front wheels by hydraulic braking force (front-wheel-side vacuum-booster hydraulic pressure fraction+linear-valve differential pressure fraction), which is frictional braking force, and regenerative braking force, and controls braking force acting on rear wheels by hydraulic braking force (rear-wheel-side vacuum-booster hydraulic pressure fraction) only, to thereby perform regeneration-coordinative brake control. During performance of ABS control, the apparatus sets the limit regenerative braking force to a force under which locking of the front wheels does not occur in a case in which the force acts on the front wheels, which are wheels undergoing regenerative braking, and adjusts the regenerative braking force such that the regenerative braking force does not exceed the limit regenerative braking force.Type: GrantFiled: March 29, 2006Date of Patent: August 11, 2009Assignee: Advics Co., Ltd.Inventors: Shigeru Saito, Masahiro Matsuura, Koichi Kokubo, Yuji Sengoku
