1. A sensor calibration device comprising a control circuit configured to:
- acquire a measured value of an attitude of a vehicle based on an output of an attitude sensor;
acquire vehicle speed information indicating a traveling speed of the vehicle;
acquire map information on a road on which the vehicle travels; and
set a calibration value applied to the measured value to cause a calculated position of the vehicle calculated based on the vehicle speed information and the measured value to come close to a reference position indicated in the map information.

Abstract
A sensor calibration device acquires a measured value of an attitude of a vehicle based on an output of an attitude sensor, acquires vehicle speed information indicating a traveling speed of the vehicle, acquires map information on a road on which the vehicle travels, and sets a calibration value applied to the measured value to cause a calculated position of the vehicle calculated based on the vehicle speed information and the measured value to come close to a reference position indicated in the map information.
