Method for monitoring dynamic loading capacity of automobile tyre based on wheel-mounted intelligent sensing

Abstract

The invention discloses a method for monitoring the dynamic loading capacity of an automobile tyre based on wheel-load intelligent sensing, and the method comprises the steps: respectively sensing thethree-dimensional acceleration of a wheel, the section height of the tyre and the pressure temperature of the tyre by using a three-axis accelerometer, a laser ranging sensor and a pressure temperature sensor of a wheel-mounted intelligent sensor; calculating the sinkage of a tyre by using the tyre section height parameter; calculating the roll angle of the wheel by using the three-dimensional acceleration parameter of the wheel; calculating the dynamic loading capacity of the tyre by using the sinkage of the tyre, the roll angle of the wheel and the pressure temperature parameter of the tyre; performing the fusion analysis of the data of the sinkage of the tyre, the roll angle of the wheel, the pressure temperature parameter of the tyre and the dynamic loading capacity to obtain a changetrend of the dynamic loading capacity of the tire. Through the wheel-load intelligent sensing measurement technology, the method achieves the real-time monitoring of the dynamic loading capacity of the automobile tyre, prevents the overloading from causing the damages to the tyre and the explosion of the tyre, and guarantees the safety performance of the tyre, the driving safety of an automobileand the traffic safety of a road.

Problems solved by technology

[0005] At present, the tire load capacity is only obtained through standard search or calculation of the static load capacity, and there is no real-time monitoring of the tire dynamic load capacity during the driving process of the motor vehicle, and the load capacity of the tire in the state of inflation pressure changes and radial deformation has not been analyzed. , so that the dynamic load capacity of the tire cannot be effectively obtained, which is not conducive to the prediction and evaluation of surface safety risk factors such as non-overloading of the vehicle and non-super static load capacity of the tire, and failure to take effective measures in time to prevent tire overloading. traffic accident
