METHOD FOR ACQUIRING VEHICLE STEERING ANGLE, APPARATUS, DEVICE, AND STORAGE MEDIUM

A method for acquiring a vehicle steering angle, an apparatus, a device, and a storage medium, the method comprising: when a vehicle is traveling according to a preset mode, obtaining vehicle test data and calculating first vehicle steering angle data corresponding to each piece of vehicle test data; utilizing first steering wheel encoder data in the vehicle test data as well as corresponding first vehicle steering angle data and performing fitting, and obtaining a correspondence relationship between steering wheel encoder data and vehicle steering angle data; when the vehicle is traveling normally, obtaining second steering wheel encoder data; and subsequently obtaining second vehicle steering angle data corresponding to the second steering wheel encoder data according to the correspondence relationship between the steering wheel encoder data and the vehicle steering angle data. Consequently, the present method can save on costs of installation and maintenance of a steering angle sensor, improve the accuracy of vehicle steering angle data, and improve automated driving operating reliability.
