Method for testing tire performance

Abstract

The invention discloses a method for testing tire performance. The method comprises the steps of installing TPMS equipment on a vehicle, obtaining tire pressure data and GPS data of the vehicle periodically and uploading the data to a cloud platform. Tread pattern depths are manually measured and are uploaded to the cloud platform with sensor IDs of the corresponding tires, and the cloud platformobtains the mileage wear ratio of tread pattern wear values of all tires within all time periods to a corresponding travelled mileage through calculation, and shows factors influencing the mileage wear ratio of the tires. The cloud platform calculates a remaining traveled mileage and the total mileage of the whole life period of the tires according to the mileage wear ratio and the remaining treadpattern depths of the tires, and measures the tire performance as a whole. The method for testing the tire performance has the advantages that the tire temperature, the tire pressure, and the tire state of the tires can be monitored in real time, and the influence of the tire state, the travelling road condition and the travelling speed on the mileage wear ratio of the tires is further detailed.In the meanwhile, the tires are bonded with the sensors, and it can be effectively avoided that the tire data is mixed.

Description

technical field [0001] The invention relates to the technical field of automobile detection, in particular to a method for testing tire performance. Background technique [0002] Tires are important accessories for vehicle driving and are consumables. The performance of tires directly affects the work efficiency, transportation cost and traffic safety of the fleet, so the test of tire performance has economic value, social value and application value. [0003] The current performance test of tires is mainly measured by the ratio of tire mileage and tread wear. The realization method is mainly to manually check the odometer on the vehicle regularly, and then measure the tread depth of the tire during this period, and calculate the mileage of the tire during this period by dividing the mileage during this period by the tread wear during this period wear ratio. For example, check the vehicle odometer L1 at time t1 and measure the tire tread depth D1; check the vehicle odomet...

AI Technical Summary

Problems solved by technology

[0004] The problem of this method is: 1, there is no process monitoring of the tire state; 2, there is no analysis of the running track and road conditions of the tire, because the mileage wear ratio of the same tire running on different roads is different; The running speed of the tire is monitored during the process, because the mileage wear ratio of the same tire running at different speed levels is different; 4. When the tire position is changed, it is easy to cause confusion in the tire pattern data, resulting in inaccurate calculation results; 5. It requires specialized testers to collect data for a long time, and the workload of manual statistics is heavy, which is prone to calculation errors
