  • Patent number: 10300912
    Abstract: 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.

  • Publication number: 20190100197
    Abstract: An avoidance route calculation part calculates an avoidance route for avoiding a collision between an own vehicle and an obstacle through a collision avoidance assist control (an automatic brake control and an automatic steering control). A post-avoidance route calculation part calculates a post-avoidance route. A post-avoidance route collision determination part determinates whether a secondary obstacle is present on the post-avoidance route. When the secondary obstacle is determined to be present, the automatic steering control is prohibited from being performed.

  • Publication number: 20180339670
    Abstract: 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.

  • Publication number: 20180261094
    Abstract: 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.

  • Patent number: 9643602
    Abstract: 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.
