  • Patent number: 9623869
    Abstract: A collision prevention controller mounted on a subject vehicle receives lane line information from a first environment recognizer and three-dimensional object information on a target three-dimensional object from a second environment recognizer, estimates the visual range of the driver based on the lane line information, determines whether the target three-dimensional object is located outside of the visual range of the driver, and determines the possibility of a collision of the target three-dimensional object and the subject vehicle. When the target three-dimensional object is located outside of the visual range of the driver, the collision prevention controller executes at least either one of notification to the driver or application of automatic braking in accordance with the possibility of collision with the subject vehicle.

  • Publication number: 20170057544
    Abstract: A vehicle traveling control apparatus includes a vehicle parameter detector, a vehicle parameter estimator, a disturbance-suppressing parameter calculator, an addition rate changer, and a disturbance suppressor. The vehicle parameter detector detects a vehicle parameter. The vehicle parameter estimator estimates, by means of a vehicle model, a vehicle parameter to be outputted in response to an input value. The disturbance-suppressing parameter calculator estimates, based on the vehicle parameters detected by the vehicle parameter detector and estimated by the vehicle parameter estimator, a disturbance generated at a vehicle, and calculates a disturbance-suppressing parameter. The addition rate changer identifies, based on the vehicle parameters detected by the vehicle parameter detector and estimated by the vehicle parameter estimator, the disturbance generated at the vehicle, and variably sets, based on the identified disturbance, an addition rate of the disturbance-suppressing parameter.

  • Patent number: 9499171
    Abstract: When a vehicle equipped with a driving support apparatus moves from an original traveling lane into a lane for passing in order to pass a preceding vehicle and an oncoming vehicle appears in the lane for passing, the safe passing of the preceding vehicle is determined to be impossible and the passing is interrupted even when the oncoming vehicle decelerates, in the case where a deceleration change amount of the oncoming vehicle is smaller than a threshold. On the other hand, when the deceleration change amount of the oncoming vehicle is equal to or greater than the threshold, whereby safety with respect to surrounding vehicles can be confirmed, and it is determined the vehicle can be safely returned in front of the preceding vehicle, the passing of the preceding vehicle is performed.

  • Patent number: 9493163
    Abstract: When an oncoming vehicle in an oncoming lane is detected in the case where a vehicle equipped with a driving support apparatus moves to a position across a portion of a boundary between an original traveling lane of the vehicle and the oncoming lane in order to pass a preceding vehicle, passing control is interrupted. When the departure of the oncoming vehicle from the oncoming lane is confirmed, the interruption of the passing control is canceled and the passing is performed. When the oncoming vehicle does not depart, or when it the oncoming vehicle is determined to depart but a vehicle following the oncoming vehicle is detected, the interruption of the passing control is maintained and the vehicle is returned to behind the preceding vehicle in the original traveling lane.

  • Publication number: 20160132055
    Abstract: In a travel control apparatus for a vehicle, a travel environment information acquisition unit acquires travel environment information on a travel environment of the vehicle. A travel information detector detects travel information on the vehicle in order to execute automatic driving control based on such information pieces. A lateral force generator generates lateral force to be applied to the vehicle during the automatic driving control. A torsion bar is interposed on a torque transmission path of a steering system. A steering wheel angle detector detects a steering wheel angle. A lateral force detector detects the lateral force acting on the vehicle. An intervening steering operation determination unit determines that a driver has performed an intervening steering operation when a characteristic of the detected steering wheel angle and lateral force differs from a reference characteristic that varies univocally when the steering wheel is in a no load condition.

  • Patent number: 9227663
    Abstract: Feed-forward control amounts of an electric motor, which are necessary for a vehicle to travel along the target course under the feed-forward control, are calculated on the basis of the road shape. The prediction time is variably set to be shorter as the present displacement between the target course and the vehicle position becomes larger, the position after elapse of the prediction time is defined as a forward gaze point, and the feedback control amounts of the electric motor, which are necessary for the vehicle to travel along the target course under the feedback control, are calculated on the basis of the traveling state of the vehicle so as to zero the displacement between the target course and the vehicle trajectory in the forward gaze point. The electric motor current value is then calculated from the driver steering torque, feed-forward control amounts, and feedback control amounts.

  • Patent number: 9223311
    Abstract: A vehicle driving support control apparatus receives lane line information given from a first environment recognizer and information on a target three-dimensional object given from a second environment recognizer. The apparatus estimates the visual range of a driver based on the lane line information, and estimates the driving lane based on at least either one of the lane line information and the target three-dimensional object information, and estimates the driving track of the vehicle. Based on the estimated driving lane and driving track, the apparatus estimates a deviation position where the subject vehicle will deviate from the driving lane on the basis of the driving lane and the driving track estimated. If the deviation position is beyond the visual range, the apparatus executes at least either one of notification to the driver and automatic braking in accordance with the possibility of deviation from the driving lane.
