Description

Technical Field

[0001] This utility model relates to the field of fault detection technology, and in particular to a fault detection device for the central control function of automotive electronic ECU. Background Technology

[0002] In the complex systems of automobiles, the Electronic Control Unit (ECU) is the core "brain," bearing the heavy responsibility of comprehensive control over the engine or motor. Based on its built-in program, it performs precise calculations, efficient processing, and accurate judgments on a large amount of information fed back from various sensors, and then outputs commands to drive the relevant actuators, thereby achieving rapid, accurate, and automated adjustment of the engine or motor's operating status. In the ECU production process, testing is crucial. If a faulty ECU enters the market and is used in vehicles, it is highly likely to pose serious safety hazards to vehicle operation and even cause accidents. Therefore, rigorous ECU production testing is a key step in ensuring vehicle safety performance and avoiding potential dangers, and is of great significance for maintaining road traffic safety.

[0003] A Chinese patent with publication number CN217333169U discloses a fault detection device for the central control function of an electric vehicle ECU. When needed, the device is first installed with the electric vehicle through a housing, and the data cable is inserted into the corresponding terminal block. The middle part of the data cable passes through the inside of the mounting cavity and is fixed by upper and lower blocks. Then, the detector is fixed by a fixing post to prevent the detector from shaking. When it is necessary to check the wiring position on the back of the detector, the fixing post is first removed, allowing the detector to rotate around the rotating post as a rotation axis with the cooperation of the rotating post and bearing, thereby checking the wiring.

[0004] Regarding the aforementioned technologies, when testing the central control function, it is necessary to start the vehicle for troubleshooting. When the vehicle is started, the body will continuously vibrate slightly, causing the test terminals to shake, which will affect the accuracy of the test. At the same time, when using the tester, it is necessary to constantly adjust the direction of the tester for observation, which may cause the tester to tip over, affecting the testing efficiency.

Multiple sets of elastic elements 2512 are fixedly mounted inside the annular groove 2511. A damping ring 252 is slidably mounted inside the annular groove 2511, and its outer side is fixedly connected to the elastic element 2512. A connector 253 is fixedly installed on the inner side of the device. The connector 253 is connected to the wiring. When it is necessary to perform fault detection on the ECU central control unit 1, the fault detection device 2 is first fixed on one side of the ECU central control unit 1 by the clamping component 24. One end of the wiring is inserted into the inside of the connector 253, and the other end of the wiring is connected to the ECU central control unit 1. At this time, the ECU central control unit 1 is initially checked for faults. After the test is completed, the vehicle is started to test the ECU central control unit 1 of the running vehicle. The damping ring 252 and the elastic element 2512 at one end of the wiring elastically limit the vibration amplitude of the connector 253 during vehicle operation, thereby reducing the error of the test.
