And the GUI tool acquires parking process data and parking result data and then imports the parking process data and the parking result data into a target file 6 for storage, wherein the GUI tool is a Matlab-based GUI tool. Preferably, the GUI test interface provided by the GUI tool provides a display area for parking process data and parking result data in addition to the display area for the test sequence test.No and parking environment parameters (such as Speed, Left/Right, Pilot _ W/L, La _ Dis in FIG. 5).

The parking time can also be manually timed by a tester, based on which, a display window of the timing result of the parking time is provided on the GUI test interface, and a corresponding timing button is correspondingly provided, such as the start timing button on the left side in fig. 5, the tester clicks the timing button when the test vehicle starts parking, and clicks the timing button again when the parking is completed, and the GUI tool counts the time spent between two times of clicking the timing button as the display window of the parking time record to the timing result, thereby completing the manual timing process of the parking time. Similarly, the pull-out time may also be manually timed by a tester, and the corresponding display layout of the GUI test interface is the same as the manual timing of the pull-out time, which is not described herein again.
