Abstract
A determination unit that determines a positional change of a radar apparatus mounted on a vehicle including a vehicle body is provided with a reference member, a displacement sensor and displacement determining means. The reference member is fixed to the vehicle body and disposed such that at least a part of the reference member is adjacent to the radar apparatus. The displacement sensor detects a displacement of the radar apparatus with respect to the reference member. The determining means determines whether or not a position of the radar apparatus has changed with respect to the vehicle body, based on the displacement detected by the displacement sensor.
Claims8
A determination unit that determines a positional change of a radar apparatus mounted on a vehicle including a vehicle body, the determination unit comprising:
- a reference member fixed to the vehicle body and disposed such that at least a part of the reference member is adjacent to the radar apparatus;
- a displacement sensor that detects a displacement of the radar apparatus with respect to the reference member;
- and
- displacement determining means for determining whether or not a position of the radar apparatus has changed with respect to the vehicle body, based on the displacement detected by the displacement sensor, wherein
- the radar apparatus is fixed to the vehicle body via a predetermined exterior part, and the reference member is fixed to the vehicle body other than at the exterior part, and
- the reference member protrudes to the exterior part from the vehicle body.
A determination unit that determines a positional change of a radar apparatus mounted on a vehicle including a vehicle body, the determination unit comprising:
- a connecting member that connects the vehicle body and the radar apparatus;
- a strain sensor that detects a strain of the connecting member itself;
- and
- strain determination means for determining whether or not a position of the radar apparatus is changed with respect to the vehicle body, based on the strain detected by the strain sensor.
A determination method for determining a positional change of a radar apparatus mounted on a vehicle including a vehicle body, the determination method comprising:
- preparing a reference member and a displacement sensor that detects a displacement of the radar apparatus with respect to the reference member;
- arranging the reference member to be fixed to the vehicle body such that at least a part of the reference member is adjacent to the radar apparatus;
- detecting a displacement of the displacement sensor;
- and
- determining whether or not a position of the radar apparatus has changed with respect to the vehicle body, wherein
- the radar apparatus is fixed to the vehicle body via a predetermined exterior part, and the reference member is fixed to the vehicle body other than at the exterior part, and
- the reference member protrudes to the exterior part from the vehicle body.
