Abstract

The invention discloses a system and method for monitoring loads on tires in real time in the automobile driving process. The method is characterized by including the steps of firstly, calibrating mapping relations of the loads on the tires of an automobile, pressure on the tires, temperatures of the tires and perpendicular deformation amounts of rubber tire bodies of the tires through bench tests; secondly, evaluating the loads on the tires in real time in the automobile driving process through an automobile velocity test device, a tire pressure monitoring device, a tire velocity sensor and the like. The method is mature in concept, the designed monitoring device has high test accuracy, and the vehicle model application range is wide.

Description

technical field [0001] The invention belongs to the field of automobile testing and control, and in particular relates to a real-time tire load monitoring system during automobile running. Background technique [0002] With the rapid development of the automobile industry, drivers have gradually increased their requirements for automobile performance, especially in terms of tire performance. Tire manufacturers need to analyze the use data of their tire products after they are put on the market to improve tire performance to meet the requirements of drivers and increase market share. Therefore, tire manufacturers urgently need a test method with wide application range, high test accuracy, and low cost for the collection and analysis of tire use data. Among them, the vertical load of the tire is an important parameter in the tire use data. [0003] The force of the tire closely affects the driving safety of the car. The forces required by the car during normal driving, such a...
