Abstract
A sensor calibration ECU includes: a calibratability determination portion that determines whether or not a distance image sensor is in a calibratable state on the basis of at least one of the state of a vehicle and the state of a road surface on which the vehicle is positioned; and a calibration execution portion that calibrates the distance image sensor on the basis of a pre-found distance (=reference distance) between the distance image sensor and the road surface on which the vehicle is positioned, when it is determined by the calibratability determination portion that the distance image sensor is in the calibratable state.
Claims13
A sensor calibration device that calibrates a distance-measuring sensor that is mounted in a vehicle, characterized by comprising:
- a calibratability determination portion that determines whether or not the distance-measuring sensor is in a calibratable state based on at least one of state of the vehicle and state of a road surface on which the vehicle is positioned;
- and
- a calibration execution portion that calibrates the distance-measuring sensor based on a pre-found distance between the distance-measuring sensor and the road surface on which the vehicle is positioned, when it is determined by the calibratability determination portion that the distance-measuring sensor is in the calibratable state.
