Patent number: 7529600Abstract: A target vehicle path is corrected in accordance with the environment surrounding a vehicle during parking assist or U-turn assist. To achieve the target vehicle path, target wheel speeds are set for respective wheels so as to generate a speed difference an inside wheel and an outside wheel of a turn. The target wheel speed is achieved by controlling braking force and driving force of each wheel. Thus, it is possible for the vehicle to turn with a smaller turning radius than that generated by a normal steering angle, and to cause the vehicle to move accurately along the target vehicle path that avoids any obstacles that are present.Type: GrantFiled: April 21, 2005Date of Patent: May 5, 2009Assignee: Advics Co., Ltd.Inventors: Yukio Mori, Kazutaka Kato, Kazuhiro Kamiya, Masahiro Matsuura

Patent number: 7356396Abstract: An automatic steering control performs an automatic parking control which automatically steers steerable wheels of a vehicle, without requiring a driver to perform steering wheel operation, such that the actual steering angle of the steerable wheels follows a changing target steering angle, whereby the vehicle is moved to a target parking state. When the actual steering angle fails to follow the target steering angle because of insufficiency of the steering drive force of a steering actuator, a braking force difference imparting control is performed so as to apply a predetermined braking force on the steerable wheel located inside a target vehicle locus. As a result, a steering moment is generated in the steerable wheels. This steering moment serves as a force for compensating for the insufficiency of the steering drive force of the steering actuator. As a result, the actual steering angle accurately follows the target steering angle.Type: GrantFiled: June 2, 2005Date of Patent: April 8, 2008Assignee: Advics Co., Ltd.Inventors: Yukio Mori, Kazutaka Kato, Kazuhiro Kamiya, Masahiro Matsuura

Publication number: 20080009996Abstract: 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: ApplicationFiled: November 7, 2006Publication date: January 10, 2008Applicant: ADVICS CO., LTD.Inventors: Shigeru Saito, Koichi Kokubo, Masahiro Matsuura, Yuji Sengoku

Patent number: 7234786Abstract: A vehicular brake control apparatus detects risky occasions and locations that may be risky by using, for example, an infrastructure information input device or a navigation device, and, for such locations and the like, performs the pre-charge so that braking force will be promptly generated. Therefore, the pre-charge can be precisely performed under necessary circumstances, irrespectively of the driver's accelerator operation. Hence, when the driver depresses the brake pedal at such a location or the like, braking force will be promptly generated. Thus, accidents and the like can be prevented.Type: GrantFiled: March 10, 2005Date of Patent: June 26, 2007Assignee: Advics Co., Ltd.Inventors: Yukio Mori, Kazutaka Kato, Kazuhiro Kamiya, Masahiro Matsuura

Publication number: 20070046099Abstract: 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: ApplicationFiled: August 22, 2006Publication date: March 1, 2007Inventors: Masahiro Matsuura, Koichi Kokubo, Shigeru Saito, Yuji Sengoku

Publication number: 20070018499Abstract: 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: ApplicationFiled: July 12, 2006Publication date: January 25, 2007Inventors: Koichi Kokubo, Masahiro Matsuura, Shigeru Saito, Yuji Sengoku
