Abstract

A vehicle control device includes a recognizer that is configured to recognize an object around a subject vehicle, a driving controller that is configured to control a speed or steering of the subject vehicle, and a predictor that is configured to predict that a predetermined vehicle will move to a front of the subject vehicle on a subject lane. The driving controller is configured to perform a behavior control in a case where it is predicted that the predetermined vehicle will move to the front of the subject vehicle on the subject lane and limits the vehicle behavior control in a case where it is predicted that the predetermined vehicle does not move to the front of the subject vehicle on the subject lane as compared with a case where it is predicted that the vehicle will move to the front of the subject vehicle on the subject lane.

First claim

What is claimed is:

1. A vehicle control device comprising:
a processor; and
a memory communicatively coupled to the processor, the memory having stored therein computer-executable components, the computer-executable components comprising:
a recognizer that recognizes an object around a subject vehicle;
a driving controller that controls at least one of a speed and steering of the subject vehicle based on a position of the object recognized by the recognizer; and
a predictor that predicts whether a predetermined vehicle will move to a front of the subject vehicle on a subject lane in response to the recognizer recognizing whether the predetermined vehicle is present at a position at which the predetermined vehicle is able to cross the subject lane on which the subject vehicle is present,
wherein, the driving controller performs a predetermined vehicle behavior control in preparation for an entry of the predetermined vehicle to the subject lane in response to a prediction by the predictor that the predetermined vehicle will move to the front of the subject vehicle on the subject lane and a recognition of the predetermined vehicle by the recognizer,
the driving controller limits the predetermined vehicle behavior control in response to a prediction by the predictor that the predetermined vehicle does not move to the front of the subject vehicle on the subject lane by the predictor and the recognition of the predetermined vehicle by the recognizer, and
the predictor predicts whether the predetermined vehicle will move in front of the subject vehicle on the subject lane based on at least one of (i) presence or absence of another vehicle within a predetermined distance in front of the subject vehicle, (ii) presence or absence of an operation of a turn signal lamp provided in the predetermined vehicle, (iii) presence or absence of an adjacent lane that is adjacent to the subject lane, or (iv) presence or absence of a predetermined point is present for changing the progress direction of the vehicle according to a road structure,
wherein, in response to the prediction by the predictor that the predetermined vehicle will move to the front of the subject vehicle on the subject lane, the recognizer increases a degree of recognition accuracy of an object of a lane different from the subject lane.

2. The vehicle control device of claim 1 ,
wherein the subject vehicle is traveling in a direction that intersects with a direction of travel of the predetermined vehicle.

3. The vehicle control device of claim 1 ,
wherein, in response to a prediction by the predictor that the predetermined vehicle will move to the front of the subject vehicle on the subject lane before the predetermined vehicle is present in the front of the subject vehicle and the subject vehicle will move in front of the predetermined vehicle, the driving controller performs the predetermined vehicle behavior control.

4. The vehicle control device of claim 1 ,
wherein, in response to the recognizer not recognizing that another vehicle is present within a predetermined distance in front of the subject vehicle and that the predetermined vehicle will not enter the subject lane and stop, the predictor predicts that the predetermined vehicle will not move in front of the subject vehicle on the subject lane.

5. The vehicle control device of claim 1 ,
wherein the recognizer recognizes presence or absence of an operation of a turn signal lamp provided in the predetermined vehicle, and
the predictor predicts whether the predetermined vehicle will move to the front of the subject vehicle on the subject lane according to the recognized presence or absence of the operation of the turn signal lamp.

6. The vehicle control device of claim 5 ,
wherein, in response to the recognizer recognizing operation of a turn signal lamp on a side close to the subject vehicle among a plurality of turn signal lamps provided in the predetermined vehicle, the predictor predicts that the predetermined vehicle will move to the front of the subject vehicle on the subject lane.

7. The vehicle control device of claim 1 ,
wherein the recognizer recognizes a plurality of lanes including the subject lane, and
in response to the recognizer recognizing the plurality of lanes and not recognizing another vehicle within a predetermined distance in front of the subject vehicle on the subject, the predictor predicts that the predetermined vehicle will move to the front of the subject vehicle on the subject lane in response to the predetermined vehicle not entering the subject lane.

8. The vehicle control device of claim 1 ,
wherein the recognizer recognizes a plurality of lanes including the subject lane and an adjacent lane that is adjacent to the subject lane, and
in response to the recognizer recognizing the adjacent lane that one or more other vehicles are present on the adjacent lane, the predictor predicts whether the predetermined vehicle will move to the subject lane and enter the adjacent lane.

9. The vehicle control device of claim 8 ,
wherein the recognizer recognizes whether a predetermined point is present for changing the progress direction of the vehicle according to a road structure, and
in response to the recognizer recognizing that the predetermined point is present in front of the position at which the predetermined vehicle is able to cross the subject lane on which the subject vehicle is present, the predictor predicts that the predetermined vehicle will move to the subject lane and enter the adjacent lane.

10. The vehicle control device of claim 1 ,
wherein the recognizer recognizes whether a pedestrian is present, and
in response to the recognizer recognizing that the pedestrian is present in front of the position at which the pedestrian is able to cross the subject lane on which the subject vehicle is present, the predictor predicts whether the predetermined vehicle will move to the front of the subject vehicle on the subject lane.

11. A vehicle control device comprising:
a processor; and
a memory communicatively coupled to the processor, the memory having stored therein computer-executable components, the computer-executable components comprising:
a recognizer that recognizes an object around a subject vehicle;
a driving controller that controls at least one of a speed and steering of the subject vehicle based on a position of the object recognized by the recognizer; and
a predictor that predicts whether a predetermined vehicle will move to a front of the subject vehicle on a subject lane in response to the recognizer recognizing whether the predetermined vehicle is present at a position at which the predetermined vehicle is able to cross the subject lane on which the subject vehicle is present,
wherein, in response to a prediction by the predictor that the predetermined vehicle will move to the front of the subject vehicle on the subject lane in a case where the recognizer recognizes the predetermined vehicle, the recognizer is configured to increase a degree of recognition accuracy of an object of a lane different from the subject lane, and
the recognizer increases the degree of recognition accuracy based on at least one of (i) presence or absence of another vehicle within a predetermined distance in front of the subject vehicle, (ii) presence or absence of an operation of a turn signal lamp provided in the predetermined vehicle, (iii) presence or absence of an adjacent lane that is adjacent to the subject lane, or (iv) presence or absence of a predetermined point is present for changing the progress direction of the vehicle according to a road structure,
wherein, in response to the prediction by the predictor that the predetermin
