Description

Technical Field

[0001] The present invention relates to the technical field of controller testing, and particularly to a testing mechanism for vehicle controllers. Background Art

[0002] Existing vehicle controllers, especially liquid heater controllers, Figure 1 in actual testing, it is necessary to conduct inlet and outlet passage tests, electrical tests on high-pressure and low-pressure interfaces in sequence. In addition, it is necessary to detect whether the entire housing is leaking when the internal electricity is turned on. Since each test requires independent connection to the corresponding interface, the whole testing is time-consuming and laborious. Moreover, the connection of existing interfaces all requires manual plugging and setting. During actual plugging operations, there are differences in the reliable plugging and unplugging of interfaces by operators, and there may be situations where inaccurate detections are caused due to unreliable plugging and unplugging. Therefore, it is necessary to develop a testing mechanism for single-station and full-range detection of vehicle controllers, so as to save testing time and improve the accuracy of testing.
