Publication number: 20220237923Abstract: An object detection device is configured to be mounted to an own vehicle to detect an object present around the own vehicle. The object detection device includes a coordinate acquisition section and an object recognition section. The coordinate acquisition section acquires position coordinates of a detection point corresponding to the object on the basis of a plurality of images captured at different positions along with movement of the own vehicle by one imaging section mounted to the own vehicle. The object recognition section recognizes the object without using position coordinates of a movement point that is a detection point corresponding to a moving object but using position coordinates of a stop point that is a detection point different from the movement point.Type: ApplicationFiled: April 12, 2022Publication date: July 28, 2022Inventors: Youhei SUZUKI, Yoshiki HAYAKAWA, Hidenori TANAKA, Akihiro KIDA, Kunihiro SUGIHARA, Yutaka HAMAMOTO, Masumi FUKUMAN

Patent number: 11393220Abstract: An obstacle identification apparatus acquires an image that is captured by a camera that is mounted to a vehicle. The obstacle identification apparatus calculates a first gradient that is a gradient in a first direction of a luminance value of pixels in the image and a second gradient that is a gradient of the luminance value in a second direction orthogonal to the first direction of the first gradient. Based on the first gradient and the second gradient, the obstacle identification apparatus estimates a shadow boundary that is a boundary between an own-vehicle shadow that is a shadow of the own vehicle and an object outside the vehicle. Based on the estimated shadow boundary, the obstacle identification apparatus estimates the own-vehicle shadow.Type: GrantFiled: October 12, 2020Date of Patent: July 19, 2022Assignees: DENSO CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takuya Miwa, Takayuki Hiromitsu, Yutaka Hamamoto, Masumi Fukuman, Akihiro Kida, Kunihiro Sugihara

Patent number: 9988027Abstract: A brake system includes a brake activator which controls, when a slipping condition is detected at a central rear wheel based on a signal detected by a central rear detector, the operating condition of a central rear brake based on the signal detected by the central rear detector so as to reduce a braking force on the central rear wheel lower than a braking force which is obtained as a result of operation of an input member. In this state, when an operation quantity of the input member increases as a result of operation of the input member, changing the operating conditions of both a right front brake and a left front brake, the brake activator increases the braking forces in both a right front wheel and a left front wheel according to an operation quantity of the input member.Type: GrantFiled: October 29, 2014Date of Patent: June 5, 2018Assignees: YAMAHA HATSUDOKI KABUSHIKI KAISHA, ADVICS CO., LTD.Inventors: Hiroaki Seto, Kunihide Ohashi, Takeshi Yamamura, Yoshinori Tsuji, Hideki Takada, Kunio Kajihara, Masato Terasaka, Yutaka Hamamoto
