PROCESSING DEVICE

WIPO Patent Application WO/2021/161656

A1

Provided is a processing device that calculates, on the basis of a steering angle detection value of a steering angle sensor for detecting the steering angle of a steering wheel of a vehicle, the offset amount of the steering angle detection value, to thereby enable correction of the the steering angle detection value. The processing device executes the following processes. P1: a recording process for acquiring the curving direction and the curvature radius of a road on which a vehicle travels and the speed and the steering angle detection value of the vehicle, associating the speed and the steering angle detection value of the vehicle traveling along the curve with the curving direction and the curvature radius of the curve, and recording the associated result as curve data. P2: a classification process for classifying the curve data into right curve data and left curve data on the basis of the direction. P3: an extraction process for extracting relevant right curve data and left curve data. P4: a calculation process for calculating an offset amount on the basis of the steering angle detection value of the extracted right curve data and the steering angle detection value of the extracted left curve data. P5: a correction process for correcting the steering angle detection value on the basis of the offset amount.
