  • Patent number: 11760374
    Abstract: A vehicle alert apparatus acquires an object distance between an object and a vehicle, presumes a predicted moving route of the vehicle when the object distance is shorter than or equal to a threshold object distance. The vehicle alert apparatus calculates a collision distance which the vehicle has moves along the predicted moving route until the vehicle collides with the object or the vehicle has moved to a position closest to the object when determining that the vehicle potentially collides with the object, based on the predicted moving route. The vehicle alert apparatus performs a first alert when the collision distance is larger than a threshold collision distance. The vehicle alert apparatus performs a second alert having a higher alert level of alerting the driver than the alert level of the first alert when the collision distance is shorter than or equal to the threshold collision distance.

  • Patent number: 11124182
    Abstract: A surroundings monitoring apparatus obtains the position of an object from a captured image of a region in a heading direction of a vehicle, and obtains a position obtainment accuracy. When the distance between the object and the vehicle becomes relatively short, the position obtainment accuracy increases. However, the distance between the object and the vehicle becomes shorter, the position obtainment accuracy may decrease. Therefore, if collision avoidance control is performed for an object selected on the basis of the position obtainment accuracy, there is a possibility that the collision avoidance control is not performed for an object which is most likely to collide with the vehicle. In view of this, the apparatus obtains, for each object, a required deceleration which is the magnitude of acceleration necessary for stoppage at a position before the object, and performs the collision avoidance control for an object which is the largest in the required deceleration.

  • Patent number: 11104355
    Abstract: A parking support apparatus determines whether or not a leaving condition becomes satisfied while the controller is executing the automatic parking control and the current shift range is at range other than a parking range, the leaving condition being a condition that is satisfied when the driver performs a leaving action. The parking support apparatus determines whether or not the vehicle has already reached the target parking area. The parking support apparatus generates a first alert having a first alerting capability, if the vehicle has already reached the target parking area when the leaving condition has been satisfied, and generates a second alert having a second alerting capability lower than the first alerting capability or no alerts, if the vehicle has not reached the target parking area yet when the leaving condition has been satisfied.
