Abstract

A recognition support system includes: an object detection device detecting an object that is located in a periphery of a host vehicle; a direction sensing device sensing a direction to which a driver intends to turn the host vehicle; a range setting device setting a notification range based on the direction sensed by the direction sensing device; a selecting device defining the object, which is detected by the object detecting device, as a specified object when the object moves independently from the host vehicle, and selecting the specified object, which is located within the notification range, to be presented to the driver based on a state of the specified object; and an information presenting device presenting an information enabling the driver to recognize the specified object selected by the selecting device.

Claims

1. A recognition support system comprising:

an object detecting device detecting an object that is located in a periphery of a host vehicle;

a direction sensing device sensing a direction to which a driver intends to turn the host vehicle;

a range setting device setting a notification range based on the direction sensed by the direction sensing device;

a selecting device defining the object, which is detected by the object detecting device, as a specified object when the object moves independently from the host vehicle, and selecting the specified object, which is located within the notification range, to be presented to the driver based on a state of the specified object; and

an information presenting device presenting an information enabling the driver to recognize the specified object selected by the selecting device, wherein

the selecting device defines the specified object as a first priority object that is preferentially presented to the driver, when the specified object is located within a predetermined range including a pedestrian crossing located ahead of the host vehicle that is about to turn,

the selecting device defines the specified object as a second priority object that is preferentially presented to the driver, when the specified object is estimated to enter the pedestrian crossing within a predetermined time period, and

the second priority object located out of driver'"'"'s field of vision is presented more preferentially.

2. The recognition support system according to claim 1, wherein:

the range setting device broadens the notification range as a speed of the host vehicle increases.

3. The recognition support system according to claim 1, wherein:

the selecting device defines the specified object as a third priority object that is preferentially presented to the driver, when the specified object is located at a position without a guard rail.

4. The recognition support system according to claim 1, wherein:

the specified object is one of a pedestrian and a bicycle.

5. A recognition support system comprising:

an object detecting device detecting an object that is located in a periphery of a host vehicle;

a direction sensing device sensing a direction to which a driver intends to turn the host vehicle;

a range setting device setting a notification range based on the direction sensed by the direction sensing device;

a selecting device defining the object, which is detected by the object detecting device, as a specified object when the object moves independently from the host vehicle, and selecting the specified object, which is located within the notification range, to be presented to the driver based on a state of the specified object; and

an information presenting device presenting an information enabling the driver to recognize the specified object selected by the selecting device, wherein

the selecting device defines the specified object as a first priority object that is preferentially presented to the driver, when the specified object is estimated to enter a pedestrian crossing located ahead of the host vehicle that is about to turn, and

when the first priority object is located out of driver'"'"'s field of vision, the first priority object located out of the driver'"'"'s field of vision is more preferentially presented to the driver than the first priority object located within the driver'"'"'s field of vision.

6. The recognition support system according to claim 5, wherein:

the range setting device broadens the notification range as a speed of the host vehicle increases.

7. The recognition support system according to claim 5, wherein:

the selecting device defines the specified object as a second priority object that is preferentially presented to the driver, when the specified object is located within a predetermined range including a pedestrian crossing located ahead of the host vehicle that is about to turn.

8. The recognition support system according to claim 7, wherein:

the second priority object is more preferentially presented to the driver than the first priority object.

9. The recognition support system according to claim 5, wherein:

the selecting device defines the specified object as a third priority object that is preferentially presented to the driver, when the specified object is located at a position without a guard rail.

10. The recognition support system according to claim 9, wherein:

the first priority object is more preferentially presented to the driver than the third priority object.

11. The recognition support system according to claim 5, wherein:

the specified object is one of a pedestrian and a bicycle.

12. A recognition support system comprising:

an object detecting device detecting an object that is located in a periphery of a host vehicle;

a direction sensing device sensing a direction to which a driver intends to turn the host vehicle;

a range setting device setting a notification range based on the direction sensed by the direction sensing device;

a selecting device defining the object, which is detected by the object detecting device, as a specified object when the object moves independently from the host vehicle, and selecting the specified object, which is located within the notification range, to be presented to the driver based on a state of the specified object; and

an information presenting device presenting an information enabling the driver to recognize the specified object selected by the selecting device, wherein

the selecting device defines the specified object as a first priority object that is preferentially presented to the driver, when the specified object is located within a predetermined range including a pedestrian crossing located ahead of the host vehicle that is about to turn,

the selecting device defines the specified object other than the first priority object as a second priority object that is preferentially presented to the driver, when a guard rail is not located between the specified object other than the first priority object and the host vehicle, and

the selecting device defines the specified object other than the first priority object as a non-presented object that is not to be presented to the driver, when the guard rail is located between the specified object other than the first priority object and the host vehicle.

13. The recognition support system according to claim 12, wherein:

the range setting device broadens the notification range as a speed of the host vehicle increases.

14. The recognition support system according to claim 12, wherein:

the selecting device defines the specified object as a third priority object that is preferentially presented to the driver, when the specified object is estimated to enter the pedestrian crossing within a predetermined time period.

15. The recognition support system according to claim 14, wherein:

when the third priority object is located out of driver'"'"'s field of vision, the third priority object located out of driver'"'"'s field of vision is more preferentially presented to the driver than the third priority object located within the driver'"'"'s field of vision.

16. The recognition support system according to claim 14, wherein:

the first priority object is more preferentially presented to the driver than the third priority object, and
