Multifunctional test system for performance test of electronic throttle valve

Abstract

The invention relates to a multifunctional test system for a performance test of an electronic throttle valve. The system comprises a switch matrix unit connected with a to-be-tested electronic throttle valve via a matched connector, an output unit for outputting a test result, and a main control unit provided with a data acquisition part and connected with the switch matrix unit and the output unit; the switch matrix unit is connected with a test device for performing at least one performance test project of the electronic throttle valve; the performance test project comprises an angle sensor signal test, a linearity test, and a synchronization test of the electronic throttle valve, a resistance change test of a non-chip C-type electronic throttle valve, a programming function and chip test of an NC type electronic throttle valve with a chip, and a clamping and stagnation test and a response time test of the electronic throttle valve; and the main control unit controls a driving motor in the electronic throttle valve to drive a throttle valve body, processes acquired tested signals of the electronic throttle valve, and sends the test result to the output unit. The system is advantaged by high universality, good expandability, high practicality, and easy operation.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a multifunctional testing system for electronic throttle performance testing. Background technique [0002] In modern society, automobiles are closely related to people's daily work and life. As an important control component in automobile engines, electronic throttle valves play an important role in ensuring and improving the power, stability, safety, fuel economy and It is of great significance to reduce pollutant emissions. However, there are some deficiencies in the design, manufacture and detection of electronic throttle valves at present. [0003] For example, in figure 1 shows the typical general situation of multiple performance item tests for the electronic throttle in the prior art. Specifically, an electronic throttle product may have a series of products such as G1, G2, G3, etc. in practical applications, and each of the series of products may have many models such...

Problems solved by technology

In addition, once there is a product design update, new test items need to be added

Therefore, in order to complete all the required test items, the existing method must replace many different types of test equipment and test personnel to operate one by one

In particular, even if some updates or improvements are made to the existing electronic throttle products in terms of structure, function, etc., it may be necessary to design and manufacture new test devices to complete the corresponding tests. This process is not only time-consuming and laborious , and the input cost is high and the requirements for personnel are high, which affects the research and development progress and reduces work efficiency
