Embodiment Construction

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

[0008] Automobile ABS and EBD comprehensive test system consists of comprehensive tester controller 1, comprehensive tester bench 2, tow bar 3, tension meter 4, front wheel speed sensor 5, comprehensive tester front wheel 6, data acquisition card 7, brake 8. , The rear wheel speed sensor 9, the comprehensive tester is composed of the rear wheel 10.

[0009] In the development and test research of the automobile ABS control system, the comprehensive test system is towed by the vehicle through the tow bar 3 and runs on the test road. The developed controller 1 controls any one of the two rear wheels 10 of the comprehensive tester. To conduct ABS control strategy research on this wheel. The wheel speed signals of the front wheels 6 and the rear wheels 10 of the comprehensive tester can be used to calculate the controlled slip rate of the rear wheels during braking; by detecting the change...

Abstract

The invention discloses an ABS / EBD comprehensive test system of an automobile. The main body structure of the system is composed of a comprehensive tester rack 2, a draw bar 3, a comprehensive tester front wheel 6 and comprehensive tester rear wheels 10, wherein the front wheel 6 is installed on the comprehensive tester rack 2 by a forerake steering king pin, two rear wheels adopt the same wheel 10, a brake 8 and a wheel speed sensor 9, and two wheels can brake and control by respective brake 8 arranged thereon; the comprehensive tester can be dragged by a vehicle via the draw bar 3, and two rear wheels 10 can serve as brake control objects researched by the test; a tensometer 4 measures wheel braking force, and the front wheel 6 can serve as a fifth wheel gauge and serve as the ABS and EBD control test research and comprehensive test system; when brake control is not carried out on two rear wheels 10 of the comprehensive tester, the front wheel serves as the fifth wheel gauge and can carry out the finished-automobile ABS and EBD control test research and comprehensive test on a tow vehicle.

Description

Technical field [0001] The invention relates to a comprehensive test technology of automobile ABS / EBD control test research and performance test. Automobile ABS (Anti-lock Braking System) device refers to automobile brake anti-lock device, and automobile EBD (Electronic Brake Force Distribution) device refers to automobile electronic brake force distribution device. Background technique [0002] At present, the more well-known manufacturers of automobile dynamic control test benches at home and abroad are Link Company and Greening Company in the United States, and Schenck Company in Germany. The current automobile ABS and EBD test benches are relatively simple in function, and can only perform vehicle braking control performance tests, and it is not easy to conduct system development test research. These functions are not integrated to achieve comprehensive test functions. Summary of the invention [0003] The automobile ABS and EBD comprehensive test system is a three-wheeled be...
