  • Patent number: 11938924
    Abstract: In a driving assistance control apparatus for a vehicle, an acquirer acquires a detected traveling state of the vehicle and a detected traveling state of another vehicle. A controller determines whether to perform braking assistance using a deterministic indicator for collision including at least one of a time, a distance, and a required deceleration to collision with the other vehicle and a deterministic indicator for crossing including at least one of a time, a distance, and a required deceleration to reaching a path of travel of the other vehicle. The deterministic indicator for collision and the deterministic indicator for crossing are acquired using the acquired traveling state of the vehicle and the acquired traveling state of the other vehicle. Further, in response to determining to perform the braking assistance, the controller causes a driving assistance unit to perform the braking assistance.

  • Patent number: 11919533
    Abstract: An alert apparatus starts alerting a driver of a host vehicle, when an oncoming vehicle, that is an other vehicle traveling in an oncoming lane with respect to a traveling lane in which the host vehicle is traveling so as to approach the host vehicle and that is predicted to pass through on a specific direction side with respect to a current position of the host vehicle, is present, a turn signal indicator of the host vehicle corresponding to the specific direction side is being operated, and it is likely that the host vehicle starts turning to the specific direction side.

  • Publication number: 20210380083
    Abstract: A braking assist control device for a vehicle including a detector and a braking assist control device is provided. The braking assist control device includes an acquisition unit configured to acquire information on an ambient environment of an own vehicle from the detector, and a control unit configured to cause the braking assist device to perform intersection entry prevention assist in a case where it is determined, using the acquired information on the ambient environment, that the own vehicle is approaching an intersection and an own lane in which the own vehicle is traveling is a non-priority lane with respect to an intersecting lane.

  • Publication number: 20210370924
    Abstract: A driving assistance apparatus is configured to identify a target as a crossing target when a vehicle and the target are expected to collide with each other in an intersecting region, configured to decelerate the vehicle at a first deceleration from a first timing before an expected collision timing that the vehicle and the crossing target are expected to collide with each other, and configured to decelerate the vehicle at a second deceleration from a second timing when the crossing target is still present at a second timing immediately before a third timing defined such that the vehicle is not stoppable at a position immediately before entering the intersecting region in a case where the vehicle starts to decelerate from the third timing at a second deceleration having an absolute value larger than an absolute value of the first deceleration.

  • Patent number: 9043045
    Abstract: A travel assist apparatus performs assist of warning or auxiliary for preventing departure of a vehicle in a lateral direction of the vehicle. A value of the estimated time to lane crossing at which assist is to be performed is varied in accordance with the velocity of the vehicle in the lateral direction. This enables selection of a value of the estimated time to lane crossing at which assist is to be performed that is suitable for the velocity of the vehicle in the lateral direction, enabling optimization of the timing of performing assist. Therefore, assist of warning or auxiliary is performed in an optimal way without bothering the driver.
