Problems solved by technology
Although it is feasible to detect the tire pressure, the result of the detection is the tire pressure, not the direct acting vertical force. The tire pressure is easily affected by the deformation of the tire (material) and the ambient temperature, and the relationship between the tire pressure and diameter The accuracy of the conversion of the axial force needs to be verified, which leads to the problem of low accuracy and poor accuracy of wheel load measurement

The invention discloses a wheel load test system, method and device. The system comprises a sensor used for detecting load data between an automobile wheel axle and a plate spring suspension corresponding to a wheel to be detected, and the sensor is fixed between the automobile wheel axle and a mounting joint surface of the plate spring suspension through a fastener; and a processor which is usedfor determining the wheel load of the wheel to be measured according to the load data acquired by the sensor. According to the system, technical problems of low accuracy and poor accuracy of a mode ofdetermining the wheel load by monitoring the tire pressure of the vehicle in related technologies are solved.
Description
technical field [0001] The invention relates to the field of automobile safety, in particular to a wheel load testing system, method and device. Background technique [0002] With the continuous development of the automobile industry, modern automobiles have made great progress in terms of intelligence and safety. safety technology. The front axle (front axle) of a car is an extremely important part of the vehicle. It is related to vehicle performance, safety, steering stability, etc., and the load distribution of the front axle is the most important, especially for cars. The change of dynamic axle load has a great influence on the steering and braking performance of the vehicle, and because the change of the axle load of each wheel in the driving state of the vehicle is relatively complicated, it is mainly affected by the center of mass of the vehicle, the way of loading, and the nature of the cargo (whether it is fluid and easy to deform) etc.), driving status, road cond...
