Abstract
The system includes a vehicle body sensor attached to a vehicle body of a work machine, a work implement sensor attached to a work implement of the work machine to detect a roll angle of the work implement, and a controller communicably connected to the sensors. The vehicle body sensor detects roll, pitch, and yaw angles of the vehicle body. The controller acquires the roll and pitch angles of the vehicle body detected by the vehicle body sensor, acquires the roll angle of the work implement detected by the work implement sensor, calculates a yaw angle error of the vehicle body sensor with respect to the vehicle body based on the pitch angle of the vehicle body and a difference between the roll angle of the vehicle body and the roll angle of the work implement, and calibrates the vehicle body sensor using the yaw angle error.
