An embodiment of the present invention provides a method, device, electronic device, and storage medium for processing steering parameters of a vehicle. The method includes: acquiring the steering wheel rotation angle of the vehicle to be tested; determining the trajectory of the vehicle to be tested at a preset driving speed Parameters, wherein the trajectory parameters include the measurement parameters of the fitting arc obtained after fitting the driving trajectory of the vehicle to be tested; according to the measurement parameters of the fitting arc and the wheelbase of the vehicle to be measured, determine at least A rotation angle of a front wheel; based on the rotation angle of at least one front wheel and the steering wheel rotation angle, a vehicle steering parameter of the vehicle to be tested is determined. Through the technical solution in the embodiment of the present invention, the influence of the installation error of the measuring device is avoided, the accuracy of the steering ratio of the vehicle is improved, and it is not limited to the type of the vehicle to be tested, and has a wide range of applications.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a method, device, electronic equipment and storage medium for processing vehicle steering parameters. Background technique [0002] The vehicle steering ratio is the ratio of the steering wheel rotation angle of the vehicle to the wheel rotation angle, and is an important parameter to ensure that the vehicle can steer according to the driver's will. At present, the method for determining the steering ratio of a vehicle is usually to install a vehicle steering ratio measuring device on the vehicle to be tested, and the measuring device measures the angular velocity of the wheels of the vehicle to be tested during driving, thereby determining the steering ratio of the vehicle. [0003] In the vehicle steering ratio determination method in the related art, the measurement device needs to be installed and disassembled during the process of measuring the vehicle steering ratio, wh...
