Virtual instrument-based vehicle ABS (Antilock Brake System) test and control system and test method

Abstract

The invention relates to a virtual instrument-based vehicle ABS (Antilock Brake System) test and control system and a test method. An ABS is a test object to be tested, and a speed of vehicle is simulated by using a rotating speed of a motor; speed governing control on the motor is realized through regulating the frequency of a genera inverter; a fly wheel is used for simulating partial motion inertias of the vehicle; and a magnetic powder clutch is used for controlling the magnitude of input current and regulating the output torque by using a computer so as to simulate different road surfaceattachment coefficients and simulate the partial motion inertias of the vehicle. The whole test process can be controlled by a program of the computer, thus the test function of all items to be tested can be changed through changing the program of the computer; hardware equipment is combined with software programming, a hardware device is simply installed, and a virtual test panel is visual and easy to use; and the advantages of high data acquisition speed and test precision, good repeatability, capability of saving a large amount of time and labor, great improvement of test efficiency and high reliability are achieved.

Description

technical field [0001] The invention relates to a test technology, in particular to an automobile ABS measurement and control system based on a virtual instrument. Background technique [0002] With the rapid development of my country's automobile industry, people pay more and more attention to traffic safety issues, and the increase of vehicle speed puts forward higher requirements for the vehicle braking system. Cars equipped with ABS (Anti-lock Braking System) can greatly improve the steering stability of the car during braking, thus ensuring driving safety to a certain extent. Therefore, it is particularly important to detect the performance of ABS to ensure its quality. Whether the test system selection is reasonable or not is directly related to whether the performance of ABS can be well detected. How to use a suitable test control system to accurately test the relevant performance of ABS, and then judge the performance of the product by analyzing the data in the test...
