Radiation anti-interference test method and device, storage medium and TCU test system

Abstract

The invention provides a radiation anti-interference test method and device, a storage medium and a TCU test system.The method comprises the steps that after an upper computer module receives a test request, the upper computer module awakens a CAN network where a TCU module to be tested is located according to the test request, the test request is sent to a CAN network where the TCU module to be tested is located; after the to-be-tested TCU module obtains the test request through a CAN network, various electronic units in the load box module are controlled to execute corresponding preset actions under different duty ratios according to the test request; after the electronic units execute corresponding preset actions, the monitoring module detects and records all state data of the TCU module to be detected in sequence. The radiation anti-interference test method provided by the invention can maximally check the capability of the TCU module for bearing radiation interference, and has the advantages of simplicity in operation, high accuracy and low test cost.

Description

technical field [0001] The invention relates to the technical field of TCU electromagnetic compatibility, in particular to a radiation anti-interference test method, equipment, storage medium and a TCU test system. Background technique [0002] With the rapid development of automobile electronic control and the application of computer and information technology, more and more electronic control technologies are applied to automobiles, and the automobile electronic control system has achieved rapid development. Automatic transmission electronic control unit (Transmission Control Unit) is one of the core control systems of vehicles equipped with automatic transmission. [0003] The automatic transmission electronic control unit can process various sensor signals indicating the current vehicle driving state during the running of the car, so as to judge the driver's willingness to control the current vehicle gear. As the electronic components on the car tend to be complicated ,...

Problems solved by technology

[0004] However, when the traditional TCU module is tested for anti-interference, it usually uses a simulated load for testing. During the test, the function that the TCU module needs to open is relatively simple, and it is difficult to check the ability of the TCU module to withstand radiation interference to the maximum extent, resulting in the TCU module anti-interference The test results are less accurate
