Problems solved by technology

However, because the contact pressure between the tire and the ground and the pressure inside the tire are not the same object, the load of the vehicle obtained by the detection method is not accurate enough
In addition, the existing methods of monitoring the load of vehicles usually use wireless sensor gateways and wireless sensor networks to transmit data to the monitoring center. Sending to the monitoring center cannot achieve the purpose of real-time monitoring

Embodiment Construction

[0096] It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0097] The invention provides a TPMS-based vehicle load detection method. Such as figure 1 As shown, in an embodiment of the present invention, the vehicle load detection method based on TPMS includes the following steps:

[0098] Step S10: TPMS collects the gas pressure value P in each tire of the vehicle under load 1 ,P 2 ,...,P n and gas temperature value T 1 , T 2 ,...,T n , and wirelessly send the gas pressure value P 1 ,P 2 ,...,P n and gas temperature value T 1 , T 2 ,...,T n transmitted to the load processing module, where n is the total number of tires of the vehicle;

[0099] Step S20: The load processing module receives the gas pressure value P 1 ,P 2 ,...,P n and gas temperature value T 1 , T 2 ,...,T n , and use the following formula (1) to calculate the load on each ti...

Abstract

The invention discloses a TPMS-based vehicle load detection method. The method includes the following steps that: a TPMS acquires gas pressure intensity values of P1, P2,..., Pn and gas temperature values of T1, T2,..., Tn in each tire under the load condition of a vehicle, wherein n is the total number of the tires of the vehicle; a load processing module calculates the load on each tire of the vehicle through adopting a formula mentioned in the descriptions of the invention; and after obtaining the load M1, load M2,..., load Mn on each tire of the vehicle, the load processing module calculates the total load Mz of the vehicle through adopting a formula that Mz=alpha1M1+alpha2M2+...alphanMn, wherein alpha1, alpha2,..., alphan are the weight coefficients of each tire, and alpha1+alpha2+... alphan=1. With the TPMS-based vehicle load detection method of the invention adopted, the total load of the vehicle can be detected more accurately. The invention also discloses a TPMS-based vehicle load detection device, a vehicle real-time load monitoring method and a vehicle real-time load monitoring system.

Description

technical field [0001] The present invention relates to the technical field of transportation and intelligent measurement and control, in particular to a vehicle load detection method and device based on a tire pressure monitoring system (TPMS for short), and a vehicle real-time load monitoring method and system. Background technique [0002] Now when testing the load of a vehicle, the usual method is to assume that the tire is a hollow cylinder, and the contact surface between the outer diameter of the tire and the ground is regarded as a rectangular contact surface, and the internal pressure of the tire is obtained according to the principle of action force and reaction force The pressure on the rectangular contact surface part is equal to the supporting force of the ground on the tire (ie Mg=PS), and the load on the tire is calculated by only detecting the gas pressure inside the tire. However, since the contact pressure between the tire and the ground and the pressure in...
