Patent number: 11858510Abstract: A vehicle drive assist apparatus includes an external environment recognizer, a traveling environment recognizer, and a processor. The traveling environment recognizer recognizes travel lane sides of dividing lines defining a travel lane as two approximate lines each in a linear form based on the image data on a traveling environment acquired by the external environment recognizer. When a static three-dimensional object has been continuously detected on or near one of dividing lines based on the image data, the processor sets a virtual approximate line by correcting the lateral position of the approximate line of the one of the dividing lines in a direction apart from the static three-dimensional object toward the middle of the travel lane by a predetermined correction amount, and sets a target travel course in the middle between the virtual approximate line and the approximate line of the other of the dividing lines.Type: GrantFiled: October 4, 2021Date of Patent: January 2, 2024Assignee: SUBARU CORPORATIONInventors: Keisuke Motegi, Masatoshi Minakawa

Publication number: 20230017726Abstract: A vehicle control system includes a detector and a processor. The detector is configured to detect a first stop line on the basis of map data stored in a road map database, and detect a second stop line on the basis of traveling environment data acquired by a camera unit. In a case where the detector detects the first stop line, the processor is configured to control a vehicle to decelerate at a first deceleration rate calculated on the basis of a distance from the vehicle to the first stop line. In a case where the detector detects the second stop line after detecting the first stop line, the processor is configured to control the vehicle to decelerate at a second deceleration rate calculated on the basis of a distance from the vehicle to the second stop line and stop at the second stop line.Type: ApplicationFiled: June 29, 2022Publication date: January 19, 2023Inventors: Yuya INNAMI, Masatoshi MINAKAWA, Daiki KOIKE, Toshihiro HAYASHI, Ryo FUKUHARA

Publication number: 20230001895Abstract: A driving assistance device for a vehicle includes a traveling environment recognizer, a braking force learner, and a braking force complementer. The traveling environment recognizer is configured to recognize traveling environment information related to an outside of the vehicle. The braking force learner is configured to, in a case where a driver who drives the vehicle has started a brake operation against a braking target recognized ahead based on the traveling environment information before a timing set based on a correlation between the vehicle and the braking target, acquire a braking force characteristic learning value based on a braking force generated from start to end of braking performed by the brake operation. The braking force complementer is configured to, in a case where the driver has started the brake operation after the set timing, complement the braking force based on the braking force characteristic learning value.Type: ApplicationFiled: June 24, 2022Publication date: January 5, 2023Inventors: Toshihiro HAYASHI, Daiki KOIKE, Yuya INNAMI, Masatoshi MINAKAWA, Ryo FUKUHARA

Publication number: 20230001918Abstract: A vehicle control system includes a vehicle estimator and a stop position setter. The vehicle estimator is configured to make determination on whether an entering vehicle entering an oncoming lane from an intersecting road is present, and estimate an overall length of the entering vehicle upon determining that the entering vehicle is present. The intersecting road intersects a traveling road where a vehicle to which the vehicle control system is applied is traveling. The stop position setter is configured to set a stop position of the vehicle based on the determination made by the vehicle estimator as to whether the entering vehicle is present and the estimated overall length of the entering vehicle.Type: ApplicationFiled: June 24, 2022Publication date: January 5, 2023Inventors: Daiki KOIKE, Masatoshi MINAKAWA, Toshihiro HAYASHI, Yuya INNAMI, Ryo FUKUHARA

Patent number: 10984258Abstract: A vehicle traveling environment detecting apparatus includes first to third stereo cameras, first to third image processors, and an image controller. The first stereo camera includes first and second cameras. The second stereo camera includes the first camera and a third camera. The third stereo camera includes the second camera and a fourth camera. The first to third image processors are configured to perform stereo image processing on first to third outside images and thereby determine first to third image processing information including first to third distance information, respectively. The first to third outside images are configured to be obtained through imaging of an environment outside the vehicle by the first to third stereo cameras, respectively. The image controller is configured to perform integration of the first image processing information, the second image processing information, and the third image processing information and thereby recognize a traveling environment of the vehicle.Type: GrantFiled: June 24, 2019Date of Patent: April 20, 2021Assignee: SUBARU CORPORATIONInventors: Hikaru Yoshikawa, Masatoshi Minakawa, Shota Yoshimura, Kazuki Takahashi, Keisuke Motegi

Patent number: 10933805Abstract: An automatic driving system includes a vehicle control calculator, a f recognizer, a passerby recognition calculator, and a notifier. The vehicle control calculator causes an vehicle to perform automatic traveling along a traveling route. The recognizer acquires information on a traveling environment ahead of the vehicle. The passerby recognition calculator recognizes a passerby ahead of the vehicle based on the information on the traveling environment. The notifier notifies the passerby of a recognition state that the passerby is recognized, when the passerby is recognized by the passerby recognition calculator. The passerby recognition calculator examines whether the recognized passerby is facing a direction of the vehicle based on information on the passerby, acquired by the recognizer, and specifies the passerby as a notification target passerby when recognizing the passerby facing the direction of the vehicle. The notifier notifies the recognition state to the notification target passerby.Type: GrantFiled: December 11, 2019Date of Patent: March 2, 2021Assignee: SUBARU CORPORATIONInventors: Keisuke Motegi, Hikaru Yoshikawa, Shota Yoshimura, Masatoshi Minakawa, Kazuki Takahashi, Shingo Ugajin
