The invention is suitable for the technical field of vehicle detection, and provides a measurement method and device, computer equipment and a storage medium. The measurement method comprises the following steps of: acquiring a real-time running speed, deflection time, a vehicle body yaw angle and a wheelbase of a vehicle when the vehicle deflects, and a swing angle of a steering wheel when the vehicle deflects; and obtaining the real-time transmission ratio of the vehicle according to the real-time running speed, the deflection time, the vehicle body yaw angle, the wheelbase and the swing angle. According to the measurement method and device, the computer equipment and the storage medium provided by the invention, dependence on auxiliary equipment such as a suspension is avoided, the measurement of the transmission ratio of a vehicle is simpler, the measurement efficiency of the transmission ratio of a vehicle is improved, and the method and the device are suitable for the transmission ratio measurement of mass-produced vehicles; and moreover, according to the measurement method, measurement is carried out when a vehicle is in a moving state, it is guaranteed that the transmission ratio obtained through measurement is the transmission ratio of the vehicle in actual movement, and the transmission ratio obtained through measurement has high accuracy.
Description
Technical field [0001] The present invention belongs to the field of vehicle detection, and more particularly to a measurement method, device, computer device, and storage medium. Background technique [0002] At present, with the continuous improvement and development of society, people have a higher demand for the convenience of life, with unmanned express delivery has a wide range of application scenarios, which is relatively related to vehicle control in the application scene. Higher requirements, especially the vehicle's control accuracy and the accuracy of the dynamic parameters of the vehicle. However, the dynamic parameters of the vehicle are not precise and completely disclosed, that is, the specific value is blurred, and it is necessary to do itself. [0003] The traditional measuring method of the vehicle dynamics parameter is specifically the conventional measurement method of the vehicle transmission ratio, and the vehicle hover is hoverted on the suspension to measu...
