Test stand for aging of ECU utilized by ABS of vehicle

Abstract

The invention relates to a test stand for aging of an ECU utilized by an ABS of a vehicle. The test stand comprises a framework, support plates, vertical plates, a power supply unit and a plurality of test units; the plurality of support plates are installed in the framework, wherein the plurality of support plates are in parallel with each other and there are intervals between the support plates; the vertical plates are respectively installed at a rear end of each the support plates; and the plurality of support plates are installed at each the vertical plate. According to the invention, a first signal binding post and a second signal binding post in each test unit are connected to a signal input terminal of an ECU through cables; a power supply binding post and a grounding terminal in each the test unit are connected with a power supply input terminal of the ECU; and commercial power is converted into a 0.5-volt alternating current signal with 50 HZ through a signal transformer in apower supply unit and then ECU motions are triggered continuously by the alternating current signal, so that stability and correctness of the ECU during intensely working are tested. Besides, a plurality of ECUs can be simultaneously measured through tests in proper order, so that the tests can be operated conveniently and the working efficiency can be improved.

Description

technical field [0001] The invention relates to the field of ABS equipment, in particular to an ECU aging test bench for vehicle ABS. Background technique [0002] In order to prevent the four wheels from being locked when the vehicle brakes and ensure the stability and safety of the vehicle when decelerating, the ABS system is generally installed in the vehicle. The most important part of the ABS system is the ECU, which is the heart of the ABS system. It is responsible for receiving the signal of the wheel speed. According to the input wheel speed, the slip rate of the wheel is controlled by repeatedly reducing or increasing the brake pressure on the wheel. The wheels spin, providing higher braking power. Before the ECU leaves the factory, it must undergo strict testing to ensure its stability and normal operation. However, the existing testing equipment is complex and cannot be tested in large quantities at the same time, and the work efficiency is low. Contents of the...
