DRIVING SUPPORT DEVICE, VEHICLE, DRIVING SUPPORT METHOD, AND STORAGE MEDIUM

Abstract

The present invention provides a driving support device that performs driving support of a vehicle, comprising: a detector configured to detect a surrounding situation of the vehicle; a control unit configured to operate the driving support of the vehicle in a case where a positional relationship between a detected target by the detector and the vehicle satisfies an operating condition; a specifying unit configured to specify a traveling course of the vehicle; and a determination unit configured to determine whether there is an intersecting structure that three-dimensionally intersects a traveling road of the vehicle in the specified traveling course, wherein in a case where the determination unit determines that there is the intersecting structure in the traveling course, the control unit changes the operating condition such that operation of the driving support with respect to the detected target is restricted.

Description

Claims

1. A driving support device that performs driving support of a vehicle, the driving support device comprising: a detector configured to detect a surrounding situation of the vehicle;a control unit configured to operate the driving support of the vehicle in a case where a positional relationship between a target detected by the detector and the vehicle satisfies an operating condition;a specifying unit configured to specify a traveling course of the vehicle; anda determination unit configured to determine whether there is an intersecting structure that three-dimensionally intersects a traveling road of the vehicle in the traveling course specified by the specifying unit,wherein in a case where the determination unit determines that there is the intersecting structure in the traveling course, the control unit changes the operating condition such that operation of the driving support with respect to the target detected by the detector is restricted.

2. The driving support device according to claim 1, wherein the determination unit determines whether there is the intersecting structure in the traveling course based on map information of an area including the traveling course specified by the specifying unit.

3. The driving support device according to claim 1, wherein the determination unit determines whether there is a gradient equal to or greater than a predetermined value between the vehicle and the intersecting structure in the traveling course specified by the specifying unit, andin a case where the determination unit further determines that there is the gradient equal to or greater than the predetermined value, the control unit changes the operating condition such that the operation of the driving support with respect to the target is restricted.

4. The driving support device according to claim 1, wherein the determination unit identifies a type of the intersecting structure in the traveling course specified by the specifying unit, andthe control unit changes the operating condition according to the type of the intersecting structure identified by the determination unit.

5. The driving support device according to claim 4, wherein the determination unit identifies whether the intersecting structure is a road or a railroad as the type of the intersecting structure, andthe control unit changes the operating condition such that the operation of the driving support is restricted in a case where the type of the intersecting structure is a railroad rather than in a case where the type of the intersecting structure is a road.

6. The driving support device according to claim 1, wherein the control unit restores the operating condition in a case where the vehicle passes through the intersecting structure.

7. The driving support device according to claim 1, wherein the operating condition includes that an index indicating the positional relationship has reached a threshold, andin a case where the determination unit determines that the target detected by the detector is the intersecting structure, the control unit changes the threshold such that operation of the driving support with respect to the target is restricted.

8. The driving support device according to claim 1, wherein the driving support includes deceleration support of the vehicle and/or a notification that deceleration of the vehicle is necessary.

9. The driving support device according to claim 1, wherein the detector includes a sensor having no resolution in a height direction.

10. The driving support device according to claim 9, wherein the detector is provided at a front corner portion of the vehicle.

11. The driving support device according to claim 9, further comprising a second detector configured by a sensor having resolution in the height direction and configured to detect a surrounding situation of the vehicle, wherein the control unit operates the driving support in a case where the positional relationship between the target detected by the second detector and the vehicle satisfies the operating condition, andthe control unit does not change the operating condition for the second detector even when the determination unit determines that there is the intersecting structure in the traveling course.

12. The driving support device according to claim 11, wherein the second detector is provided in a front central portion of the vehicle.

13. A vehicle comprising the driving support device according to claim 1.

14. A driving support method for performing driving support of a vehicle, the method comprising: detecting a surrounding situation of the vehicle; andoperating the driving support of the vehicle in a case where a positional relationship between a detected target and the vehicle satisfies an operating condition,wherein the operating the driving support includes determining whether there is an intersecting structure that three-dimensionally intersects a traveling road of the vehicle in a traveling course of the vehicle, andchanging, in a case of determining that there is the intersecting structure in the traveling course, the operating condition such that operation of the driving support with respect to the detected target is restricted.

15. A non-transitory computer-readable storage medium storing a program for causing a computer to execute a driving support method according to claim 14.
