SENSOR ABNORMALITY DETECTION DEVICE
First Claim
1. A sensor abnormality detection device comprising:
- a first sensor configured to detect a situation of a first region at a periphery of an own vehicle;
a second sensor configured to detect a situation of a second region at the periphery of the own vehicle, the second region being a region different from the first region and including an overlapping region that overlaps a part of the first region;
a sensor abnormality determination means configured to determine presence or absence of abnormality of the first sensor and the second sensor; and
a collision detection means configured to detect collision of the own vehicle to an object exterior to the vehicle;
whereinthe sensor abnormality determination means determines that at least one of the first sensor and the second sensor has abnormality, at the time the first region and the second region do not overlap in the overlapping region, after the collision detection means detects the collision.

Abstract
A sensor abnormality detection device includes a first sensor that detects a situation of a first region at a periphery of an own vehicle; a second sensor that detects a situation of a second region, which is a region different from the first region and includes an overlapping region that overlaps a part of the first region; a sensor abnormality determination means that determines abnormality of the first sensor and the second sensor; and a collision detection means that detects collision of the own vehicle to an object; wherein the sensor abnormality determination means determines that at least one of the first sensor and the second sensor has abnormality when the first region and the second region do not overlap in the overlapping region after the collision is detected.

4. A sensor abnormality detection device comprising:
-
a first sensor configured to detect a situation of a first region at a periphery of an own vehicle; a second sensor configured to detect a situation of a second region at the periphery of the own vehicle, the second region being a region different from the first region and including a first overlapping region that overlaps a part of the first region; a third sensor configured to detect a situation of a third region at the periphery of the own vehicle, the third region being a region different from the first region and the second region and including a second overlapping region that overlaps a part of the first region; a sensor abnormality determination means configured to determine presence or absence of abnormality of the first sensor, the second sensor, and the third sensor; and a collision detection means configured to detect collision of the own vehicle to an object exterior to the vehicle;
whereinat the time determining that at least one of the first sensor and the second sensor has abnormality at the time the first sensor and the second sensor do not detect the same situation in the first overlapping region after the collision detection means detects the collision, the sensor abnormality determination means further determines whether or not the first sensor and the third sensor detect the same situation in the second overlapping region, and at the time the first sensor and the third sensor detect the same situation in the second overlapping region, the sensor abnormality determination means determines that the first sensor does not have abnormality and the second sensor has abnormality.
