Abstract

A reliability correction device is provided in which a target-matter is detected by means of a camera and/or a radar, and a reliability modification unit included in the device modifies the degree of reliability with respect to target-matter information being detected, on the basis of an irradiation range(s) being an irradiation region(s) of a light(s).

First claim

1 . A reliability correction device for modifying a degree of reliability with respect to a detection result of a target-matter, by a sensor, existing in surroundings of said sensor, the reliability correction device, comprising:
a reliability modification device for modifying a degree of reliability with respect to target-matter information being detected, on a basis of an irradiation range being an irradiation region of a light.

2 . The reliability correction device as set forth in claim 1 , wherein the irradiation region includes an irradiation region of a light mounted on an apparatus with which said sensor is provided.

3 . The reliability correction device as set forth in claim 1 , further comprising: an illumination range calculation device for calculating the irradiation region from a range in accordance with intensity of an image obtained from said sensor.

4 . The reliability correction device as set forth in claim 1 , wherein the reliability correction device is mounted on a motor vehicle.

5 . The reliability correction device as set forth in claim 1 , wherein said sensor includes a camera.

6 . The reliability correction device as set forth in claim 5 , wherein the reliability modification device increases a value of the degree of reliability and/or raises an upper limit-level of the degree of reliability, when a location of the target-matter is inside of an irradiation region of the light.

7 . The reliability correction device as set forth in claim 5 , wherein the reliability modification device decreases a value of the degree of reliability and/or lowers an upper limit-level of the degree of reliability, when a location of the target-matter is outside of an irradiation region of the light.

8 . The reliability correction device as set forth in claim 1 , wherein said sensor includes a camera and a radar.

9 . The reliability correction device as set forth in claim 8 , wherein the reliability modification device decreases a value of the degree of reliability and/or lowers an upper limit-level of the degree of reliability, when the radar only detects a target-matter and the camera does not detect a target-matter, and when a location of the target-matter is inside of an irradiation region of the light.

10 . The reliability correction device as set forth in claim 8 , wherein the reliability modification device does not change a value of the degree of reliability and/or does not change an upper limit-level of the degree of reliability, when the camera only detects a target-matter and the radar does not detect a target-matter, and when a location of the target-matter is inside of an irradiation region of the light.

11 . The reliability correction device as set forth in claim 8 , wherein the reliability modification device raises an upper limit-level of the degree of reliability, when the camera and the radar detect a same target-matter, and when a location of the target-matter is inside of an irradiation region of the light.

12 . The reliability correction device as set forth in claim 8 , wherein the reliability modification device does not change a value of the degree of reliability and/or does not change an upper limit-level of the degree of reliability, when the radar only detects a target-matter and the camera does not detect a target-matter, and when a location of the target-matter is outside of an irradiation region of the light.

13 . The reliability correction device as set forth in claim 8 , wherein the reliability modification device decreases a value of the degree of reliability and/or lowers an upper limit-level of the degree of reliability, when the camera only detects a target-matter and the radar does not detect a target-matter, and when a location of the target-matter is outside of an irradiation region of the light.

14 . The reliability correction device as set forth in claim 8 , wherein the reliability modification device does not change a value of the degree of reliability and/or does not change an upper limit-level of the degree of reliability, when the camera and the radar detect a same target-matter, and when a location of the target-matter is outside of an irradiation region of the light.

15 . A method of modifying a degree of reliability, comprising:
a first process-step of acquiring a detection result of a target-matter, by a sensor, existing in surroundings of the sensor; a second process-step of acquiring an irradiation range being an irradiation region of a light; a third process-step of performing determination whether or not a target-matter being detected locates inside of an irradiation range of the light; and a fourth process-step of modifying a degree of reliability with respect to target-matter information being detected, on a basis of a result of determination at the third process-step.

16 . A motor vehicle operating system, comprising:
a reliability modification device for modifying a degree of reliability with respect to target-matter information being detected, with respect to a detection result of a target-matter, by a sensor, existing in surroundings of the sensor, on a basis of an irradiation range being an irradiation region of a light; and a motor vehicle control device for controlling a motor vehicle, on a basis of a target-matter detection result including a degree of reliability being modified by the reliability modification device.
