Publication number: 20240149894Abstract: A vehicle control device includes: a recognition unit configured to recognize a surrounding condition of a vehicle; a driving control unit configured to control acceleration, deceleration, and steering of the vehicle based on a recognition result; and a vehicle abnormality detection unit configured to detect an abnormality in an electric parking brake device. When an abnormality in the driver is detected during traveling of the vehicle, the driving control unit performs control to decelerate the vehicle to a predetermined speed greater than zero by braking by a brake device. In a case where an abnormality in the electric parking brake device is detected before or at a time the vehicle is decelerated to the predetermined speed, the driving control unit causes the vehicle to perform traveling along a traveling road until the recognition unit recognizes a preceding vehicle after the vehicle is decelerated to the predetermined speed.Type: ApplicationFiled: November 7, 2023Publication date: May 9, 2024Applicant: HONDA MOTOR CO., LTD.Inventors: Takuma KOBAYASHI, Yuko SUGIMURA, Yuichi MASUKAKE, Yugo KAJIWARA, Yuichi KOMORI, Shohei NOAI

Patent number: 10711689Abstract: A control device is provided capable of reliably preventing occurrence of a surging state by judging a possibility of the surging state in a relatively easy manner and promptly executing a surging state avoidance control. When a supercharging pressure decreasing state in which a target supercharging pressure decreases is detected, an operating speed of a wastegate valve is determined based on a detected engine rotational speed. That is, by lowering the operating speed as the engine rotational speed lowers, reduction in flow rate of the air passing through a compressor is prevented, and the occurrence of the surging state is reliably prevented. By lowering the operating speed instead of changing a target opening degree of the wastegate valve, a maximum opening degree of the wastegate valve can be suppressed, and responsiveness in the case where an acceleration request is made immediately after deceleration of an engine can be improved.Type: GrantFiled: June 20, 2018Date of Patent: July 14, 2020Assignee: Honda Motor Co., Ltd.Inventors: Yuichi Masukake, Tetsuya Iida, Yujiro Tsutsumi, Ayumu Horiba
