Description
Technical field
The present invention relates to the compbined test technology of automobile ABS/EBD control experimental study and performance test.Automobile ABS (Anti-lock Braking System) device is meant the automotive anti-lock braking device, and automobile EBD (Electronic Brake ForceDistribution) device is meant automotive electronics braking force distribution device.
Background technology
At present, domestic and international existing Automobile Dynamic control experiment table manufacturer is more famous U.S. Link company and a Greening company, German Schenck company etc.More single on existing automobile ABS, the EBD testing table function, can only carry out the vehicle braking control performance test, be difficult for carrying out the system development experimental study, these functions are not merged realization compbined test function.
Summary of the invention
Described automobile ABS, EBD integrated test system are three-wheel bench type structure, and agent structure is by comprehensive tester stand 2, towbar 3, and comprehensive tester front-wheel 6, comprehensive tester trailing wheel 10 is formed, as shown in Figure 1.Comprehensive tester can travel on test roads by towbar 3 by vehicle towed, by the braking of controller 1 control comprehensive tester trailing wheel 10, carries out ABS, EBD control experimental study and integration test.
Described comprehensive tester is a three-wheel bench type structure, and front-wheel 6 adopts light type wheel, is installed in by the pivot stud that leans forward on the stand 2 of comprehensive tester, has guaranteed the divertical motion of comprehensive tester, and wheel speed sensors 5 is housed on it; Back two-wheeled adopts identical wheel 10, detent 8 and wheel speed sensors 9, and two-wheeled can be respectively braked control by separately detent 8 on it, can measure the wheel speed of two wheels by its wheel speed sensors 9 separately; Slip rate in the time of can calculating the trailing wheel braking by comprehensive tester 6 front-wheels and trailing wheel 10 wheel speed signals; Can regulate the load of test wheel according to the needs of test by the counterweight on the adjusting comprehensive tester.
Described comprehensive tester can be used as ABS, EBD control experimental study and integrated test system, and comprehensive tester can travel on test roads by towbar 3 by vehicle towed; Comprehensive tester two trailing wheels 10 are as the brake control objects of experimental study, and tautness meter 4 is measured wheel braking force, and the front-wheel 6 of comprehensive tester uses as fifth wheel instrument, can be used as ABS, EBD control experimental study and integrated test system; When comprehensive tester two trailing wheels 10 not being braked control, the front-wheel 6 of comprehensive tester uses as fifth wheel instrument, can carry out car load ABS, EBD control experimental study and integration test to towing vehicle.
Description of drawings
1. comprehensive tester controller, 2. comprehensive tester stand, 3 towbars, 4. tautness meter, 5. before wheel speed sensors, 6. comprehensive tester front-wheel, 7. data collecting card, 8. detent, 9 back wheel speed sensors, 10. comprehensive tester trailing wheels
Embodiment
Describe the present invention in detail below in conjunction with accompanying drawing.
Automobile ABS, EBD integrated test system are made up of comprehensive tester controller 1, comprehensive tester stand 2, towbar 3, tautness meter 4, preceding wheel speed sensors 5, comprehensive tester front-wheel 6, data collecting card 7, detent 8, back wheel speed sensors 9, comprehensive tester trailing wheel 10.
When carrying out the research of automobile ABS control system development experiments, integrated test system is passed through towbar 3 by vehicle towed, travel on test roads, any one in two trailing wheels 10 of controller 1 control comprehensive tester that pass through to be developed braked, and this taken turns carry out the research of ABS control strategy.Slip rate in the time of can calculating the trailing wheel braking of being controlled by comprehensive tester front-wheel 6 and trailing wheel 10 wheel speed signals; By detecting the variation of slip rate, judge the ABS control performance, if do not meet the demands, further this advances control algolithm, tests again.Simultaneously, the damping force of the integrated test system trailing wheel of measuring by tautness meter 4, but the braking effect of Direct Test ABS.
When carrying out the research of automobile EBD control system development experiments, two trailing wheels 10 can be in friction factor respectively and differ bigger on the open circuit surface, pass through the controller developed 1 control comprehensive tester and control two trailing wheels 10 simultaneously and brake, the slip rate when wheel speed signal by comprehensive tester front-wheel 6 and two trailing wheels 10 can calculate the two trailing wheels braking of being controlled respectively; Test is at first only independently braked control to two trailing wheels respectively with the ABS control strategy without the EBD control strategy, with the EBD control strategy two trailing wheels are coordinated control again, relatively the slip rate variation characteristic of twice test findings two trailing wheel is judged the performance that EBD controls.By above-mentioned EBD control test method, can be respectively carry out under at bend, to operating condition of test such as open circuit surface bends, with the performance of complete examination EBD control.
When carrying out towing vehicle ABS, the experimental study of EBD car load control performance, comprehensive tester front-wheel 6 uses as fifth wheel instrument, the slip rate in the time of can calculating each wheel braking of towing vehicle respectively by comprehensive tester front-wheel 6 and each wheel speed signal of taking turns of towing vehicle; Can detect towing vehicle ABS, EBD car load control performance by slip rate.
