Abstract

An other-vehicle detector 18 of an other-vehicle detection device 10a detects an other-vehicle VO around a host vehicle VM based on the predetermined feature amount. A detection reference value adjustment unit 16 of the other-vehicle detection device 10a, regarding the feature amount for detecting the other-vehicle VO around the host vehicle VM, changes a threshold value of the feature amount for detecting the other-vehicle VO, and detects the other-vehicle VO, based on a relative positional relationship between the other-vehicle VO and the host vehicle VM. In this way, it is possible to detect the existence of the other-vehicle VO according to the situation more.

Claims

1-8. -8. (canceled)

9. An other-vehicle detection device comprising:

an other-vehicle detection unit that detects an other-vehicle around a host vehicle based on a predetermined feature amount,

wherein, based on a relative positional relationship between the other-vehicle and the host vehicle, the other-vehicle detection unit changes a threshold value of the feature amount for detecting the other-vehicle, and detects the other-vehicle, and

wherein, in a case where the relative positional relationship between the other-vehicle and the host vehicle needs to change a traveling state of the host vehicle when the other-vehicle is detected by the other vehicle detection unit but actually does not exist, the other-vehicle detection unit changes the threshold value of the feature amount for detecting the other-vehicle such that the other-vehicle is detected with more difficulty, and detects the other-vehicle.

11. The other-vehicle detection device according to claim 9,

wherein the other-vehicle detection unit detects the other-vehicle by the feature amount based on a detection value of sensors installed on the host vehicle, and changes the threshold value of the feature amount for detecting the other-vehicle based on at least any of the position where the sensors are installed and the detection direction of the sensors, and detects the other-vehicle.

10. An other-vehicle detection device comprising:

an other-vehicle detection unit that detects an other-vehicle around a host vehicle based on a predetermined feature amount,

wherein, until the traveling state of the host vehicle changes, the other-vehicle detection unit detects the other-vehicle by setting the threshold value of the feature amount for detecting the other-vehicle to the threshold value such that the other-vehicle is detected more easily, and

wherein, after the traveling state of the host vehicle changes, the other-vehicle detection unit detects the other-vehicle by setting the threshold value of the feature amount for detecting the other-vehicle to the threshold value such that the other-vehicle is detected with more difficulty.

12. The other-vehicle detection device according to claim 10,

wherein the other-vehicle detection unit detects the other-vehicle by the feature amount based on a detection value of sensors installed on the host vehicle, and changes the threshold value of the feature amount for detecting the other-vehicle based on at least any of the position where the sensors are installed and the detection direction of the sensors, and detects the other-vehicle.

13. An other-vehicle detection method for detecting an other-vehicle around a host vehicle based on a predetermined feature amount, comprising:

changing a threshold value of the feature amount for detecting the other-vehicle based on a relative positional relationship between the other-vehicle and the host vehicle, and detecting the other-vehicle,

wherein, in a case where the relative positional relationship between the other-vehicle and the host vehicle needs to change the traveling state of the host vehicle when the other-vehicle is detected but actually does not exist, the threshold value of the feature amount for detecting the other-vehicle is changed such that the other-vehicle is detected with more difficulty, and the other-vehicle is detected.

15. The other-vehicle detection method according to claim 13, wherein the other-vehicle by the feature amount is detected based on a detection value of sensors installed on the host vehicle, and

wherein the threshold value of the feature amount for detecting the other-vehicle is changed, based on at least any of the position where the sensors are installed and the detection direction of the sensors, and the other-vehicle is detected.

changing a threshold value of the feature amount for detecting the other-vehicle based on a relative positional relationship between the other-vehicle and the host vehicle, and detecting the other-vehicle,

wherein, until the traveling state of the other-vehicle being changed, the other-vehicle is detected by setting the threshold value of the feature amount for detecting the other-vehicle to the threshold value such that the other-vehicle is detected more easily, and

wherein after the traveling state of the other-vehicle being changed, the other-vehicle is detected by setting the threshold value of the feature amount for detecting the other-vehicle to the threshold value such that the other-vehicle is detected with more difficulty.

16. The other-vehicle detection method according to claim 14, wherein the other-vehicle by the feature amount is detected based on a detection value of sensors installed on the host vehicle, and
