ABS (antilock brake system)/ASR (acceleration slip regulation) comprehensive testing system for low friction vehicle

Abstract

The invention discloses an ABS (antilock brake system) / ASR (acceleration slip regulation) comprehensive testing system for a low friction vehicle, consisting of four wheel test beds which have the same function and can be controlled independently. In the system, a brake drive device (12) controls the rotating speeds of a flywheel (1) and the drive end of a slip frequency torque control device (3) to be in accordance with the theoretical wheel rotating speed which is obtained in a vehicle brake (or drive) process according to the wheel center speed; the driven end of the slip frequency torque control device (3) rotates with rotor drums (11, 9) and wheels; limiting friction between the wheels and the rotor drums is increased to be more than the actual braking force (or driving force) which is possibly generated in the wheel brake (drive) process to ensure that the slip rate (or skid ratio) between the wheels and the drums is far smaller than the slip rates (or skid ratio) at two ends of the slip frequency torque control device (3); and the slip frequency torque control device (3) controls the braking force (or driving force) generated between the wheels and the drums according to different pavement attachment conditions so as to complete the vehicle ABS and ASR performance tests under different pavement attachment conditions.

Description

technical field [0001] The invention relates to the comprehensive test technology of automobile ABS / ASR control test research and performance test. The automobile ABS (Anti-lock Braking System) device refers to the automobile anti-lock brake device, the automobile ASR (Automatic Slip Regulation) device refers to the automobile drive anti-skid device, and the automobile ABS / ASR device refers to the automobile with the brake anti-lock brake at the same time. Function and device for actuating the anti-skid function. Background technique [0002] At present, the domestic and foreign existing manufacturers of automobile dynamic control test benches are relatively well-known such as Link Company and Greening Company of the United States, Schenck Company of Germany, etc., and Beijing Institute of Technology in China also has related research and patent applications. The current automobile ABS test bench mainly tests the control performance of ABS by measuring the braking force and...
