  • Patent number: 11964653
    Abstract: A driving assistance system includes a processor and a memory that stores surroundings information indicating the surroundings of a vehicle detected by sensors mounted on the vehicle. The processor is configured to acquire the position of a target in front of the vehicle and the position of the boundary of a roadway area in front of the vehicle based on the surroundings information. The processor is configured to determine whether the target is in the roadway area based on the position of the target and the position of the boundary. The processor is configured to calculate the distance between the target and the boundary when the target is in the roadway area. The processor is configured to determine whether the target is crossing the roadway area based on the relationship between the distance and a time.

  • Publication number: 20230102842
    Abstract: A target vehicle recognition apparatus detects a stopped vehicle ahead of the host vehicle, detects a reference boundary line position where at least one of two boundary lines forming a travel lane of the host vehicle intersects a reference axis extending from a lower end of the stopped vehicle in an image horizontal direction on a captured image, recognizes the stopped vehicle as a target vehicle of steering control when the reference boundary line position between a vehicle left end position of the stopped vehicle and a vehicle right end position of the stopped vehicle is present, and does not recognize the stopped vehicle as a target vehicle of steering control when the reference boundary line position between the vehicle left end position of the stopped vehicle and the vehicle right end position of the stopped vehicle is not present.

  • Publication number: 20230102058
    Abstract: A target vehicle recognition apparatus for recognizing a target vehicle as a target to be avoided by steering control of a host vehicle detects a stopped vehicle located in front of the host vehicle, determines whether the stopped vehicle is in a forward-facing state to the host vehicle or a rearward-facing state to the host vehicle, determines whether the stopped vehicle is in a right boundary line deviation state crossing a right boundary line of a travel lane of the host vehicle, a left boundary line deviation state crossing a left boundary line of the travel lane, and recognizes the target vehicle for steering control based on a captured image captured by a front camera of the host vehicle and each of the determination results.

  • Patent number: 11305759
    Abstract: A vehicle control apparatus is provided with: a distance acquirer configured to obtain a distance between a first avoidance target and a second avoidance target in a longitudinal direction of a host vehicle when the first avoidance target is on one of left and right sides of the host vehicle and when the second avoidance target is on a far side of the first avoidance target and on another side of the host vehicle; and a controller configured or programmed to reduce a displacement amount in a lateral direction of the host vehicle, of a displacement in a direction of the host vehicle going away from the first avoidance target, which is to avoid the first avoidance target by the avoidance control, when the obtained distance is less than a predetermined distance, in comparison with when the obtained distance is greater than the predetermined distance.

  • Patent number: 11199843
    Abstract: A vehicle control apparatus is provided with: an executor configured to perform an automatic steering control of steering a vehicle so as to go away from an avoidance target object; a determinator configured to determine, during execution of the automatic steering control targeting a first object, whether or not a second object is detected; and a comparator configured to compare a first interval, which is an interval between the vehicle and the first object, with a second interval, which is an interval between the vehicle and the second object. The executor is configured to change the offset amount to an offset amount corresponding to the second object if the second interval is narrower than the first interval, and to maintain the offset amount at an offset amount corresponding to the first object if the second interval is wider than the first interval.

  • Publication number: 20200231146
    Abstract: A driving assistance apparatus includes: an executor configured to perform at least one of a deceleration control and a steering control of a host vehicle, as an avoidance assistance control; a first determinator configured to determine whether or not the target is a vehicle; a second determinator configured to determine whether the target is a stopped vehicle, which has a possibility to move before the host vehicle passes it, or parked vehicle, which does not have a possibility to move before the host vehicle passes it, if it is determined by the first determinator that the target is a vehicle; and a controller programmed to control the executor to change a control aspect of the avoidance assistance control between if it is determined by the second determinator that the target is the stopped vehicle and if it is determined by the second determinator that the target is the parked vehicle.
