Publication number: 20180178783Abstract: A collision avoidance support device comprises: target detection unit for detecting an target existing in front of a vehicle travelling on a road; target type determination unit for detecting which of a moving object and a stationary object the target detected by the target detection unit is; obstacle determination unit for determining whether or not the target detected by the target detection unit is an obstacle which is likely to collide with the vehicle; and traveling direction automatic control unit. The traveling direction automatic control unit is configured to calculate the selected avoidance path so that the distance margin of when the obstacle determination unit determines that the obstacle is the moving object is larger than the distance margin of when the obstacle determination unit determines that the obstacle is the stationary object.Type: ApplicationFiled: December 20, 2017Publication date: June 28, 2018Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Kotaro SAIKI

Publication number: 20170369054Abstract: A collision avoidance apparatus includes an obstacle detection section for detecting an obstacle, a collision avoidance section which performs collision avoidance assist control, and an avoidance processing start section for causing the collision avoidance section to start the collision avoidance assist control. In the case where the obstacle is a continuous obstacle, the timing of starting the collision avoidance assist control is delayed as compared with the case where the obstacle is not a continuous obstacle. Further, the greater the degree of gentleness of the inclination of the continuous obstacle, the greater the amount by which the timing of starting the collision avoidance assist control is delayed.Type: ApplicationFiled: June 23, 2017Publication date: December 28, 2017Inventors: Motoki Nishimura, Kotaro Saiki, Shinya Nishida

Patent number: 9643602Abstract: A parking support device 1 includes a calculation unit 17 that calculates a speed pattern, an acceleration recognition unit 13 that recognizes driver-requested acceleration, a parking support control unit 19 that performs parking support control in a target parking position based on the speed pattern, and a determination unit 18 that determines whether a host vehicle V can stop in the target parking position at a set deceleration. When the driver-requested acceleration is recognized during the control and exceeds acceleration of the speed pattern at the time of recognition, the parking support control unit 19 accelerates the host vehicle V at the driver-requested acceleration. When the determination unit 18 determines that the host vehicle V can stop in the target parking position at the set deceleration, the host vehicle V is decelerated at the set deceleration and is stopped in the target parking position regardless of the driver-requested acceleration.Type: GrantFiled: June 8, 2015Date of Patent: May 9, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Ryuji Okamura, Atsushi Sagisaka, Shinya Sannodo, Yu Hiei, Kotaro Saiki, Keisuke Hata
