Patent number: 10777081Abstract: A collision preventing ECU 10 selects an obstacle point which has probability of colliding with an own vehicle, and calculates a collision time periods (TTC) of the obstacle point. When the minimum collision time period is equal to or shorter than a threshold time period, the collision preventing ECU 10 determines that a specific condition is established, and performs a collision preventing control to prevent the own vehicle from colliding with the an obstacle. When the obstacle which includes the obstacle point whose collision time period is minimum is a continuous structure, the collision preventing ECU 10 calculates a continuous structure angle, and memory a calculation number corresponding to an angle range within which a magnitude of the continuous structure angle falls. When there is no angle range whose calculation number is more than a threshold number, the collision preventing control is prohibited.Type: GrantFiled: March 12, 2018Date of Patent: September 15, 2020Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Motoki Nishimura, Kotaro Saiki

Patent number: 10471954Abstract: 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: GrantFiled: December 20, 2017Date of Patent: November 12, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Kotaro Saiki

Patent number: 10300912Abstract: 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: GrantFiled: June 23, 2017Date of Patent: May 28, 2019Assignee: Toyota Jidosha Kabushiki KaishaInventors: Motoki Nishimura, Kotaro Saiki, Shinya Nishida

Publication number: 20180339670Abstract: A collision preventing ECU 10 determines that a support performing condition is established when a relationship between a threshold and a collision index value representing emergency degree of a collision between an object and the own vehicle satisfies with a predetermined relationship. In this case, the ECU performs a collision preventing control for preventing the collision. The ECU determines whether or not the object is a continuous structure. The ECU determines whether or not a running status is a steering operation running status. The ECU changes at least one of the collision index value and the threshold such that the support performing condition becomes more difficult to be established when a specific condition that the object is determined to be the continuous structure and the running status is determined to be the steering operation running status is established than when the specific condition is not established.Type: ApplicationFiled: May 22, 2018Publication date: November 29, 2018Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Motoki NISHIMURA, Kotaro SAIKI
