The invention relates to an automobile quality detection method, system and vehicle. The method includes: using the distance sensors installed at the four corners of the vehicle body to measure the ground clearance of the four corners of the vehicle body, and determining the total vehicle mass corresponding to the ground clearance distance of the four corners of the vehicle body according to the ground clearance distance of the four corners of the vehicle body and the pre-stored calibration information, thereby avoiding the complicated suspension structure , tire deformation, vehicle movement, tire wear and other unstable effects, and then determine the vehicle status information according to the ground clearance of the four corners and the total mass of the vehicle, and output the vehicle status information in a preset form, so that the driver can know at any time The loading status of the vehicle, so that when an abnormal situation occurs, the driver can find it in time to avoid serious consequences.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile quality inspection method, system and vehicle. Background technique [0002] In recent years, overcrowding and overloading of passenger cars have caused many accidents of mass death and mass injury. Due to overloading of trucks, bridges have been crushed and overturned, resulting in a severe shortening of the life of the road surface, and frequent occurrence of various road safety accidents. [0003] At present, the quality of the vehicle is mainly detected at the expressway toll station when weighing and tolling. If the vehicle does not enter the expressway, it is difficult to find the overloaded condition of the vehicle. For the driver, it is difficult to find out whether the loading of the vehicle is reasonable or whether there is a safety risk, even if he actively goes to the toll truck scale for weighing. [0004] Current overload detection solutions mostl...
