Abstract

A prevention safety device in course change of small-sized vehicle includes a rear vehicle detector, a detection state determining unit, and a vehicle'"'"'s own information transmitting unit. The rear vehicle detector is configured to detect a rear vehicle travelling at a rear of one'"'"'s own vehicle. The detection state determining unit is configured to determine whether the rear vehicle detects one'"'"'s own vehicle or not when the rear vehicle detected by the rear vehicle detector is an autonomous vehicle. The vehicle'"'"'s own information transmitting unit is configured to transmit vehicle'"'"'s own information to the rear vehicle immediately before one'"'"'s own vehicle changes a course when the detection state determining unit determines that the rear vehicle does not detect one'"'"'s own vehicle.

Claims

1. A prevention safety device in course change of small-sized vehicle, comprising:

a rear vehicle detection unit configured to detect a rear vehicle travelling at a rear of one'"'"'s own vehicle;

a determining unit configured to determine whether the rear vehicle detects one'"'"'s own vehicle or not when the rear vehicle detected by the rear vehicle detection unit is an autonomous vehicle; and

a transmitting unit configured to transmit vehicle'"'"'s own information to the rear vehicle immediately before one'"'"'s own vehicle changes a course when the determining unit determines that the rear vehicle does not detect one'"'"'s own vehicle, wherein;

the rear vehicle detection unit is configured to detect whether a target rear vehicle to which the vehicle'"'"'s own information is transmitted by the transmitting unit has changed a course to a lane identical to one'"'"'s own vehicle or not, and

when the determining unit determines that the target rear vehicle has changed the course to the lane identical to one'"'"'s own vehicle and determines that the target rear vehicle does not detect one'"'"'s own vehicle, the transmitting unit is configured to transmit second vehicle'"'"'s own information to the target rear vehicle.

3. The prevention safety device in course change of small-sized vehicle according to claim 1, wherein the rear vehicle detection unit is configured to detect the rear vehicle on the basis of information detected by a milliwave radar.

4. The prevention safety device in course change of small-sized vehicle according to claim 1, wherein the small-sized vehicle is a saddle-ride type vehicle.

7. The prevention safety device in course change of small-sized vehicle according to claim 1, wherein the determining unit is configured to determine whether the rear vehicle detects one'"'"'s own vehicle or not on the basis of a vehicle-to-vehicle distance with the rear vehicle.

8. The prevention safety device in course change of small-sized vehicle according to claim 7, wherein the determining unit is configured to determine that the rear vehicle does not detect one'"'"'s own vehicle when the vehicle-to-vehicle distance with the rear vehicle is shorter than a predetermined distance.

9. The prevention safety device in course change of small-sized vehicle according to claim 1, further comprising an autonomous vehicle determining unit configured to determine whether a vehicle is the autonomous vehicle or not on the basis of vehicle information received from the rear vehicle or a position lamp for automatic driving mode of the rear vehicle.

10. The prevention safety device in course change of small-sized vehicle according to claim 1, wherein the vehicle'"'"'s own information includes identification information of a vehicle and location information of one'"'"'s own vehicle.

2. A prevention safety device in course change of small-sized vehicle, comprising:

a rear vehicle detection unit configured to detect a rear vehicle travelling at a rear of one'"'"'s own vehicle;

a transmitting unit configured to transmit vehicle'"'"'s own information to a second rear vehicle immediately before one'"'"'s own vehicle changes a course when the second rear vehicle detected by the rear vehicle detection unit is an autonomous vehicle; and

a determining unit configured to determine whether the second rear vehicle detected by the rear vehicle detection unit detects one'"'"'s own vehicle, wherein;

the rear vehicle detection unit is configured to detect whether the second rear vehicle to which the vehicle'"'"'s own information is transmitted by the transmitting unit has changed a course to a lane identical to one'"'"'s own vehicle or not, and

when the determining unit determines that the second rear vehicle has changed the course to the lane identical to one'"'"'s own vehicle and determines that the second rear vehicle does not detect one'"'"'s own vehicle, the transmitting unit is configured to transmit second vehicle'"'"'s own information to the second rear vehicle.

5. The prevention safety device in course change of small-sized vehicle according to claim 2, wherein the rear vehicle detection unit is configured to detect the rear vehicle on the basis of information detected by a milliwave radar.

6. The prevention safety device in course change of small-sized vehicle according to claim 2, wherein the small-sized vehicle is a saddle-ride type vehicle.

11. The prevention safety device in course change of small-sized vehicle according to claim 2, wherein the determining unit is configured to determine whether the second rear vehicle detects one'"'"'s own vehicle or not on the basis of a vehicle-to-vehicle distance with the second rear vehicle.

12. The prevention safety device in course change of small-sized vehicle according to claim 11, wherein the determining unit is configured to determine that the second rear vehicle does not detect one'"'"'s own vehicle when the vehicle-to-vehicle distance with the second rear vehicle is shorter than a predetermined distance.

13. The prevention safety device in course change of small-sized vehicle according to claim 2, further comprising an autonomous vehicle determining unit configured to determine whether a vehicle is the autonomous vehicle or not on the basis of vehicle information received from the second rear vehicle or a position lamp for automatic driving mode of the second rear vehicle.

14. The prevention safety device in course change of small-sized vehicle according to claim 2, wherein the vehicle'"'"'s own information includes identification information of a vehicle and location information of one'"'"'s own vehicle.
