Embodiment Construction

[0007] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0008] The automotive ABS and EBD comprehensive test system is composed of two assembly parts: drum test bench 2 and comprehensive tester 4, specifically including: 1. drum test bench controller, 2. drum test bench, 3. comprehensive tester controller , 4. Comprehensive tester, 5. Comprehensive tester front wheel, 6. Data acquisition card, 7. Brake, 8. Wheel speed sensor, 9. Comprehensive tester rear wheel.

[0009] When carrying out the research and development test of the automobile ABS control system, the two rear wheels of the comprehensive tester 4 are placed on the drum of the drum test bench 2 according to the position requirements, and their longitudinal positions are limited after reaching the position requirements. The rotation of the drum drives the two rear wheels 9 of the comprehensive tester 4 to rotate, and the developed controller 3 controls any one of...

Abstract

The invention discloses an ABS/EBD comprehensive test system of an automobile, which is composed of a drum dynamometer 2 and a comprehensive tester 4, wherein the drum dynamometer 2 is fixedly installed on the foundation, two rear wheels of the comprehensive tester 4 are arranged on the drum of the drum dynamometer 2 according to the position requirement by longitudinal positioning; the drum of the drum dynamometer 2 rotates to drive two rear wheels 9 of the comprehensive tester 4 to rotate so as to carry out automobile ABS and EBD control comprehensive test research and performance test; the comprehensive tester 4 adopts three-wheel rack type structure, a front wheel 5 is installed on the rack of the comprehensive tester 4 to ensure the stability of the comprehensive tester 4; the controller 3 of the comprehensive tester 4 controls a brake 7 of two rear wheels 9 on the comprehensive tester 4 to brake; one rear wheel can be independently braked to carry out the development test research and performance test of the ABS system; two rear wheels can be simultaneously braked to distribute the braking force of two wheels, i.e. the development test research and performance test of the EBD system.

Description

technical field [0001] The invention relates to the comprehensive test technology of automobile ABS / EBD control test research and performance test. The automobile ABS (Anti-lock Braking System) device refers to the automobile anti-lock brake device, and the automobile EBD (Electronic Brake Force Distribution) device refers to the automobile electronic brake force distribution device. Background technique [0002] At present, the existing domestic and foreign manufacturers of automobile dynamic control test benches are relatively well-known such as Link Company and Greening Company of the United States, and Schenck Company of Germany. The current automotive ABS and EBD test benches are relatively single in function, and can only perform vehicle brake control performance tests, and are not easy to carry out system development test research, and have not integrated these functions to achieve comprehensive test functions. Contents of the invention [0003] The automobile ABS ...
