METHOD FOR OBTAINING VEHICLE STEERING ANGLE, EQUIPMENT, DEVICE AND DATA CARRIER Russian patent published in 2023 - IPC B62D15/02 B62D5/04 

FIELD: automatic driving technology.

SUBSTANCE: invention is related specifically to a method and equipment for obtaining the steering wheel angle of a vehicle, a device and a data carrier. The method for obtaining a vehicle steering angle comprises, when the vehicle is moving according to a predetermined mode, obtaining vehicle test data and calculating the first vehicle steering angle data corresponding to each piece of vehicle test data; using the first steering wheel encoder data in the vehicle test data and the corresponding first vehicle steering angle data, and performing an approximation, and obtaining a correspondence relationship between the steering wheel encoder data and the vehicle steering angle data. When the vehicle is running normally, the second steering wheel encoder data is obtained; and then the second vehicle steering angle data is obtained corresponding to the second steering wheel encoder data according to a correspondence relation between the steering wheel encoder data and the vehicle steering angle data.

EFFECT: saving installation and maintenance costs of the steering angle sensor, improving the accuracy of the vehicle steering angle data, and improving the operational reliability of the automatic driving.
