Problems solved by technology

Automobile braking performance can be detected indirectly through the contact sensing technology used in ABS (anti-lock brake system), but this type of detection system is not highly intelligent, and there are also problems with concealment and safety
In recent years, the monitoring technology of the built-in sensors of automobile tires has gradually become the mainstream direction of automobile safety performance monitoring technology. Using the built-in acceleration sensors of automobile tires to collect the radial acceleration during the braking period of automobiles can provide a basis for the analysis and research of subsequent automobile tire braking performance monitoring. basis, but there is no relevant technical report

Abstract

This invention disclosed a car radial acceleration testing device which consists of frame, tyre, dynamical motor, brake-operating lever, carrying axle, additional brace and circuit control panel. There are circuit control panel, dry element cell, weight equalizer on the additional brace; the circuit control panel was fixed with acceleration sensor, indicator light, start-up button, replacement button, indicator light for power working, switch. This invention could measure and record the car tyre radial acceleration by using an acceleration sensor and output the data by serial communication method.

Description

technical field [0001] The invention relates to the technical field of automobile braking performance monitoring, in particular to the application technology of radial acceleration sensed by an acceleration sensor, in particular to a radial acceleration testing device during the braking period of automobile tires. Background technique [0002] Dynamic monitoring of vehicle braking performance is an important technical measure to ensure driving safety and reduce traffic accidents. Automobile braking performance can be detected indirectly through the contact sensing technology used in ABS (anti-lock brake system), but this type of detection system is not highly intelligent, and there are also problems of concealment and safety. In recent years, the monitoring technology of the built-in sensors of automobile tires has gradually become the mainstream direction of automobile safety performance monitoring technology. Using the built-in acceleration sens...
