Patent number: 12269469Abstract: A vehicle drive assist apparatus to be applied to a vehicle executes at least emergency braking control for avoiding collision of the vehicle with a recognized object. The vehicle drive assist apparatus includes a surrounding environment recognition device and a traveling control unit. The surrounding environment recognition device includes a recognizer that recognizes a surrounding environment around the vehicle, and a feature information acquirer that acquires feature information of a target object in the recognized surrounding environment. The traveling control unit centrally controls the entire vehicle. The traveling control unit includes a determiner that determines, based on the acquired feature information, whether the target object has a possibility of hindering traveling of the vehicle.

Publication number: 20240034315Abstract: A surrounding environment around a vehicle is recognized and surrounding environment information is acquired. Traveling control is performed on the vehicle based on the acquired surrounding environment information. When an obstacle expected to hinder traveling of the vehicle is recognized ahead of the vehicle and other vehicles traveling ahead of the vehicle are recognized in an adjacent lane adjacent to a traveling lane where the vehicle is traveling, a movement amount of the obstacle moved due to an effect of a first other vehicle among the other vehicles that travels at a position near the obstacle is detected. An estimated movement amount of the obstacle moved due to an effect of a second other vehicle among the other vehicles that follows the first other vehicle is calculated based on the detected movement amount. The traveling control is performed on the vehicle based on the estimated movement amount.Type: ApplicationFiled: July 24, 2023Publication date: February 1, 2024Applicant: SUBARU CORPORATIONInventors: Reo HARADA, Hiroaki KURAMOCHI, Seiya SATO, Hiroki MANIWA, Wataru MUNEMURA, Shigeki MUKAI, Kazuyuki TAKAHASHI

Publication number: 20230227025Abstract: A surrounding environment recognition device recognizes a surrounding environment around a vehicle. A traveling control unit centrally controls a whole of the entire vehicle. An obstacle presumer presumes presence of an obstacle ahead of the vehicle based on a behavior distribution of preceding vehicles recognized by the surrounding environment recognition device, and estimates a position and an area where the obstacle is present when the presence of the obstacle is presumed. A traveling path calculator calculates candidates for traveling path areas along which the vehicle is expected to travel while avoiding collision with the presumed obstacle. A traveling path selector selects a traveling path area from among the calculated traveling path areas and sets the selected traveling path area. The traveling control unit controls the vehicle to travel along the set traveling path area.Type: ApplicationFiled: December 16, 2022Publication date: July 20, 2023Inventors: Hiroaki KURAMOCHI, Shota YASUDA, Shigeki MUKAI, Kazuyuki TAKAHASHI, Wataru MUNEMURA, Seiya SATO, Hiroki MANIWA

Patent number: 7150256Abstract: Air is aspirated by cylinders of cylinder rows (11, 12) via branch pipes (23,24) from two intake collectors (21,22) of a V type multi-cylinder internal combustion engine. An auxiliary chamber (31, 32) is formed using the space between adjacent branch pipes (23,24). A communication port (25, 26) to the intake collector (21,22) of the auxiliary chamber (31,32) is formed between the openings (23A,24A) to the intake collector (21,22) of two adjacent branch pipes (23,24). Since the effective volume of the intake collector (21,22) increases due to the auxiliary chamber (31,32), residual resonance in the intake collector (21, 22) decreases. The auxiliary chamber (31,32) increases an intake inertia effect by increasing the flow rate of the branch pipes (23,24) in the second half of the intake stroke relative to the flow rate in the first half of the intake stroke. Engine volume efficiency is thereby improved using a limited space.Type: GrantFiled: October 6, 2005Date of Patent: December 19, 2006Assignee: Nissan Motor Co., Ltd.Inventors: Yoshikazu Tsuruoka, Shigeki Mukai
