Further, the generating a test report includes: and when the MP5 interface image fault is identified, automatically generating a test report containing fault influence factor information and fault occurrence time information.
Corresponding to the above embodiments, the following specific implementations are provided herein for reference:
the tested fault part MP5 integrated with the 360-degree panorama function is placed in an automatic testing dark box, and the position of the MP5 and the position of a real-time shooting camera in the dark box are adjusted, so that the whole interface of the MP5 can be shot by the camera, and the shot image can be clearly displayed on an upper computer.
A CAN signal transmitting sub Vl program is written in LabView and is used for simulating and transmitting R gear, left/right steering, vehicle speed, wheel corner signals and the like which are transmitted to the MP5 in the actual test process, and CAN cover CAN signals required by 360 abnormal working conditions at present.
A power supply regulator Vl program is written in LabView and is used for simulating a voltage value of a storage battery and an ACC (adaptive control center) on a rack or a real vehicle when a fault phenomenon occurs in the actual test process, realizing some special voltage waveforms such as a starting voltage waveform when the whole vehicle is started, and the like, and further creating some extreme voltage conditions by changing voltage parameters to randomly change the waveforms.
An interface identifier Vl program is written in LabView and is used for automatically identifying and judging whether a fault phenomenon occurs or not, and mainly identifying some special display elements of a 360-degree panoramic interface, such as a camera, a track line and the like.
The reasons for the phenomena of 360-degree panoramic black screen, screen blocking, interface overlapping and the like are often related to the voltage value of the storage battery or the voltage value of the ACC, the switching interval time between interfaces, the CAN signal load rate required by vehicle operation or the mutual combination of the factors, in order to accurately analyze accidental fault phenomena and identify the influence factors causing the fault phenomena, a targeted test case CAN be compiled aiming at different fault phenomena, and the targeted test case CAN traverse various influence factors of the fault phenomena.

And secondly, after the fault phenomenon is rectified, the rectified software can be updated on the MP5 to be tested, and the rectification verification is carried out repeatedly by using the test cases and the test sequences which lead to the fault in advance so as to ensure the rectification effectiveness.
