This correction method for a gyro sensor (223) that measures the angular speed of a vehicle around a vertical direction axis comprises: a generation process in which correction information is obtained by performing processing on a difference between a measurement azimuth, which is obtained by performing processing on sensor output from the gyro sensor (223), and a vehicle azimuth, which is estimated using a marker disposed on a travel path of the vehicle; and a correction process in which the measurement azimuth, which is obtained by performing processing on sensor output from the gyro sensor (223), is corrected using the correction information.
对车辆绕铅垂方向的轴的角速度进行计测的陀螺仪传感器(223)的修正方法包括:对计测方位与车辆方位之间的差量实施处理而得到修正信息的生成处理,该计测方位通过对陀螺仪传感器(223)的输出即传感器输出实施处理而得到,该车辆方位通过利用配置于车辆的行驶路的标识器而推定出;以及利用修正信息来修正对陀螺仪传感器(223)的输出即传感器输出实施处理而得到的计测方位的修正处理。
