Abstract
The invention discloses an automobile antilock brake system (ABS) brake performance dynamic detection system and relates to the technical field of automobile safety driving. The automobile ABS brake performance dynamic detection system mainly comprises a motor, an electromagnetic slip clutch, an energy storage flywheel, a supporting roller, a speed measuring roller, a speed sensor, a torque sensor, a computer control system and a test result display system. By automatic control, data acquisition and analytical judgment of the detection process through a computer, the ABS dynamic performance test of the automobile braking process is completed, defects that the widely applied pavement test is high in cost, long in period, low in accuracy, influenced by pavement conditions and test environmental factors and the like in the prior art are really overcome, and the automobile ABS performance is really detected indoors.
Description
Technical field
The present invention relates to the vehicle safety travel technical field, particularly the dynamic detection system technical field of automobile ABS braking ability.
Background technology
The ABS test method that generally adopts at present both at home and abroad is to utilize slip rate to describe the test method of ABS control procedure, utilizes wheel slip directly, the dynamic changing process of each wheel is referred to as the soul of ABS in the industry in the quantitative description car brakeing process.Select this method development ABS actual road test equipment for use, a brake test finishes to obtain test result at the scene, and the scientific research institution by countries in the world is chased after high always.But since how to capture the speed of a motor vehicle/wheel speed synchronously with the key of real-time testing, how to solve technical barriers such as the speed of a motor vehicle/wheel speed is tested the contradiction of medium velocity instantaneity and precision, how to be realized length standard value high speed, dynamic, accurate transfer still unresolved.
China was from 1992; Mandatory rules of law such as GB 13594-92, GB 12676-2003, GB/T 13594-2003 and GB/T17993-2005 have been made and issued in succession with reference to foreign standard; These have been implemented and other rules that will formulate and implement; For the extensive employing of ABS on China's automobile provides Fundamentals of Law, indicating that China's automobile adorns the arriving in period with ABS in a large number.Use along with vehicle; The prolongation of automobile ABS term of life and some other factorses; All possibly cause anti-blocking brake system of automobile antilock system failure or serviceability to descend; The ABS vehicle that presses for installing additional detects, otherwise can increase this avoidable traffic hazard, ABS inferior perhaps has been installed will have caused bigger accident.The at present domestic ABS dynamic property monitor station that does not also have multi-functional, practical, reasonable price that can meeting the market requirement; Existing product is based on its principle and structure; Various road conditions in can not the simulated automotive driving process are so can not detect the automobile ABS dynamic braking system at all.
Summary of the invention
The object of the invention is to propose a kind of automobile ABS braking ability dynamic detection system.
The present invention mainly is made up of motor, electromagnetic slip clutch, accumulated energy flywheel, idler pulley, the cylinder that tests the speed, speed pickup, torque sensor, computer control system and test result display system; Computer control system is sent action command to inertia simulation controller and road-adhesion coefficient controller; Inertia simulation controller and road-adhesion coefficient controller are had an effect; Use each kinematic parameter on the sensor measurement monitor station simultaneously; And be input to computer control system to this signal through A/D conversion; Computer control system is carried out logical operation and digital computation through the signal of measuring; Draw inertia simulation controller and the road-adhesion coefficient controller action command that will carry out of following one-period, and send to inertia simulation controller and road-adhesion coefficient controller, make controller get into next working cycle through the I/O plate.
The present invention is through automatic control, the data acquisition of computer realization checkout procedure; Analysis and judgement; Accomplish the ABS dynamic performance testing of Motor Vehicle Braking Procedure; The drawback that aspects such as the pavement test expense that adopts at present extensively is high, the cycle is long, precision is low from truly overcoming, receive pavement conditions, experimental enviroment factor affecting exist really realizes the indoor detection of performance of ABS.
Project characteristic and innovation: 1. four groups of ABS detect road surface Work condition analogue system structure design technology; 2. the designing technique of frequency conversion speed-adjusting system; 3. the fast high precision high capacity of the speed of a motor vehicle/wheel, collection in real time, the tracing display technology; 4. can expanded function.
The present invention mainly is made up of motor, electromagnetic slip clutch, accumulated energy flywheel, idler pulley, the cylinder that tests the speed, speed pickup, torque sensor, computer control system and test result display system.Department of computer science's test result display system of unifying is shared in total system.Computer system is the control center of total system, sends action command to inertia simulation controller and road-adhesion coefficient controller, and inertia simulation controller and road-adhesion coefficient controller are had an effect.Use each kinematic parameter on the sensor measurement monitor station simultaneously; And being input to computing machine to this signal through A/D conversion, computing machine carries out logical operation and digital computation through the signal of measuring, and draws inertia simulation controller and the road-adhesion coefficient controller action command that will carry out of following one-period; And send to inertia simulation controller and road-adhesion coefficient controller through the I/O plate; Make controller get into next working cycle, whole testing process is carried out in the running that so goes round and begins again.The ABS+EBD evaluating finally calculates in computing machine, and estimates the performance of ABS+EBD according to the mutual relationship of evaluating and size.The testing staff at last testing result outputed on the display screen, so that can see easily.
Whole TT&C system is made up of control section, data acquisition and processing section, and control section is made up of several parts such as frequency converter asynchronous motor, powder clutch, lifting jacks; Part of data acquisition is made up of data collecting card torque rotary speed sensor, optoelectronic switch and corresponding data processing circuit etc.
