Embodiment Construction

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

[0008] Automotive ABS and EBD comprehensive test system consists of comprehensive tester controller 1, comprehensive tester bench 2, traction bar 3, pull gauge 4, front wheel speed sensor 5, comprehensive tester front wheel 6, data acquisition card 7, brake 8 , rear wheel speed sensor 9, comprehensive tester rear wheel 10 forms.

[0009] When carrying out the research and development test of the automobile ABS control system, the comprehensive test system is towed by the vehicle through the tow bar 3, runs on the test road, and controls any one of the two rear wheels 10 of the comprehensive tester through the developed controller 1. To conduct research on the ABS control strategy for this round. The slip rate of the controlled rear wheel during braking can be calculated through the wheel speed signals of the front wheel 6 and the rear wheel 10 of the comprehensive t...

Abstract

The invention discloses an automobile ABS / EBD comprehensive test system. The main structure of the system is composed of a comprehensive tester bench 2, a traction rod 3, a comprehensive tester front wheel 6, and a comprehensive tester rear wheel 10. The front wheel 6 is installed on the bench 2 of the comprehensive tester through the forward-inclined steering kingpin; the rear two wheels use the same wheel 10, brake 8 and wheel speed sensor 9, and the two wheels can be operated by their respective brakes 8. brake control. The comprehensive tester can be towed by the vehicle through the tow bar 3, the two rear wheels 10 are used as the brake control object of the test study, the tension meter 4 measures the wheel braking force, and the front wheel 6 is used as a five-wheel meter, which can be used as ABS, EBD control test Research and comprehensive test system; when the two rear wheels 10 of the comprehensive tester are not used for braking control, the front wheel 6 is used as a five-wheel tester, which can conduct experimental research and comprehensive testing of the ABS and EBD control of the towing vehicle.

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.
