Description

Vehicle air conditioner electric window function stability testing arrangement Technical Field The invention relates to the field of intelligent network automobiles, in particular to a device for testing the functional stability of an electric window of a vehicle air conditioner. Background With the popularization of intelligent network-connected automobiles, the electric air window function of an intelligent network-connected automobile interface control air conditioner air outlet is increasingly widely applied. The electric air window can realize the preset air direction one-key setting (such as blowing to a person) on the vehicle-machine interface, and can also realize the accurate adjustment of the air direction through the stepless adjustment of the user on the vehicle-machine interface. The electric air window function plays a role in improving the use comfort of the air conditioner as one of important functions of the automobile air conditioning system. The realization of the electric window function has complex link interaction from the intelligent network car-connected machine to the air conditioner controller to the electric window motor and the fan blade. The current electric window function test has the following disadvantages: Firstly, the system-level functional test is lacked, the current test mainly comprises an independent test and a whole vehicle-level test for controlling each part on a link, the system-level functional stability test for a link subsystem cannot be realized, the part-level test possibly passes but the functional stability is abnormal due to compatibility and bus communication, and the whole vehicle-level test has the problems of node lag and high vehicle manufacturing cost. Secondly, the traditional vehicle-level functional stability test is usually carried out through a manual test, and the manual test mode has the problems of time and labor waste and difficulty in ensuring the integrity and consistency of the test coverage surface; Third, the data record and the result are judged inaccurately, and the manual test cannot accurately confirm the function realization condition, for example, a tester controls a main electric air window to blow at an upward angle of 45 degrees, and the tester can hardly judge whether the electric air window blows at an accurate upward angle of 45 degrees, so that whether the function of the difficult electric air window is normal cannot be judged. Therefore, the technical problem to be solved by the embodiment of the invention at least comprises that the functional stability test of the electric window of the vehicle air conditioner lacks a system-level functional test. Disclosure of Invention In view of the above, the embodiment of the invention provides a device for testing the functional stability of an electric window of a vehicle air conditioner, which can provide a system-level functional test for the functional stability test of the electric window of the vehicle air conditioner.
