Abstract

An embodiment of the invention discloses a vehicle instrument table test method, device, system, equipment and a storage medium, and the method is characterized by comprising the following steps of determining a currently adopted test mode; determining a working mode of the chassis dynamometer and an environmental mode of environment simulation equipment according to the test mode; acquiring the actual test value of the target vehicle instrument table and the instrument table display value when the target vehicle is tested in the working mode and the environmental mode, wherein the target vehicle instrument table includes a speedometer and an odometer; and determining the test result of the target vehicle instrument table based on the actual test value and the instrument table display value. The embodiment of the invention can realize the test of the target vehicle instrument table through the chassis dynamometer in different test modes, and control the environmental conditions duringthe test through the environment simulation equipment, thereby avoiding the test error caused by the environmental condition change, increasing the test flexibility and improving test coverage and test accuracy.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of vehicle performance testing, and in particular to a vehicle instrument meter testing method, device, system, equipment and storage medium. Background technique [0002] With the development of science and technology and the improvement of people's living standards, various types of vehicles have increasingly entered people's lives. In order to ensure the safety performance of the vehicle, it is necessary to test the instruments in the vehicle through the vehicle test. The speedometer and odometer are important instruments that provide information on the vehicle's driving speed and mileage. The driver's ability to correctly grasp the vehicle's speed and mileage while driving is the key to improving transportation productivity and ensuring safe driving. The speedometer and odometer may cause errors due to the weakening of the internal magnetic field and the reduction of wheel diam...
