  • Patent number: 11364901
    Abstract: A driving support apparatus according to the invention estimates the position of a moving body by controlling a position estimation unit when the tracking-target moving body leaves a first area or a second area to enter a blind spot area and detects the position of the moving body by controlling a position detection unit when the moving body leaves the blind spot area to enter the first area or the second area. In this manner, the trajectory of the tracking-target moving body is calculated so that the trajectory of the moving body detected in the first area or the second area and the trajectory of the moving body estimated in the blind spot area are continuous to each other and driving support is executed based on the calculated trajectory of the tracking-target moving body.

  • Patent number: 9975548
    Abstract: A vehicle driving situation determination apparatus includes an object detector for detecting an object around a vehicle and an electronic control unit (ECU). The ECU calculates an index relating to a traveling state of the vehicle, wherein the index is a value that is obtained by dividing a jerk of the vehicle by a deceleration. The ECU compares the index to past index statistics, in a case where the object is detected by the object detector and then a response operation against the object by a driver of the vehicle is detected. A driving reaction of the driver of the vehicle is based on a result of this comparison and driving support is executed based on the determination.

  • Patent number: 8676441
    Abstract: An object of the present invention is to provide a steering assist device which can perform steering assist control having excellent capability to follow up a traveling path by increasing the steering amount in the steering control at a curve entrance. A steering assist device of the present invention is a steering assist device 1 for calculating a steering target value based on a shape of a traveling path on which a vehicle travels, and assisting steering according to the steering target value, wherein it is determined whether the vehicle is traveling a curve entrance of the traveling path, and when it is determined that the vehicle is traveling a curve entrance, a change in the steering target value is increased compared with the case of traveling a part of the path other than a curve entrance. As a result, a steering amount to turn the steering wheel can be increased at a curve entrance, and a delay in the turning of the steering wheel at a curve entrance can be suppressed.
