摘要： A driving assist apparatus of a vehicle of the invention predicts, as a predicted minimum left turn radius, a curvature radius of a moving route of the vehicle at a point where a curvature radius of the moving route is predicted to become smallest when the vehicle turns left, and sets a route curved along an arc having the predicted minimum left turn radius as a predicted moving route predicted for the vehicle to move. The apparatus predicts, as a predetermined minimum right turn radius, the curvature radius of the moving route of the vehicle at the point where the curvature radius is predicted to become smallest when the vehicle turns right, and sets the route curved along the arc having the predicted minimum right turn radius as the predicted moving route.

摘要： A driving assist apparatus of a vehicle of the invention sets a predicted route predicted for the vehicle to move and performs an attention operation to a driver when a time predicted for the vehicle to reach a point where a moving object crosses the predicted route is smaller than or equal to a threshold time. The apparatus predicts a radius of a route predicted for the vehicle to move as a left turn radius when the vehicle turns left and sets a route curved along an arc having the left turn radius as the predicted route. The apparatus predicts the radius of the route predicted for the vehicle to move as a right turn radius when the vehicle turns right and sets the route curved along the arc having the right turn radius as the predicted route.

摘要： A driving assistance apparatus includes a plurality of sensor devices and at least one electronic control unit. The electronic control unit estimates a linear path of a finite length extending in a traveling direction of a host vehicle as an expected path. The electronic control unit determines whether or not a target object that is an object having a possibility of crossing the expected path within a threshold time period is present, and determines whether or not a traffic situation estimated to hinder traveling of the target object occurs. The electronic control unit generates a driving assistance request signal when the electronic control unit determines that the target object is present and that the traffic situation does not occur, and forbids generation of the driving assistance request signal when the electronic control unit determines that the target object is present and that the traffic situation occurs.

摘要： A driving support apparatus estimates an expected route of an own vehicle, calculates an effective length of the expected route, and alerts a driver of the own vehicle when it is determined that there exists an object which crosses a part within the effective length within a predetermined time. A formula of a circle with a radius of an estimated turning radius is used for an expected route formula expressing the expected route. Once it is determined that the own vehicle is trying to start turning left or right, the driving support apparatus calculates a turning angle of the own vehicle, and calculates the effective length of the expected route using a value based on a product of the estimated turning radius and a remaining turning angle which is an angle obtained by subtracting the turning angle from a predetermined angle.

摘要： When a support ECU detects a crossing object approaching so as to cross a travel path toward which an own vehicle is heading, the support ECU calculates an object speed Vx, which is the speed of the crossing object. When the object speed Vx is more than a speed threshold Vref, the support ECU delivers an alert at a timing at which a margin period Tx becomes equal to or less than a time threshold Tref. On the other hand, when the object speed Vx is equal to or less than the speed threshold Vref, the support ECU alerts a driver at a timing at which a margin distance Dx becomes equal to or less than a distance threshold Dref.
