In a preferred embodiment of the present invention, the parking controller 1 outputs a scoring request after the automatic parking of the vehicle is completed;
and the man-machine interaction terminal 2 receives and displays the grading request.
Specifically, in the present embodiment, a vehicle equipped with an automatic parking system usually starts an automatic parking function when the vehicle is continuously running at a low speed, the automatic parking function is used for searching for a parking space during the running of the vehicle, and when a user confirms that automatic parking is adopted, an automatic parking start instruction may be input through a central control large screen of the vehicle or a mobile terminal that is in communication connection with the vehicle, and the parking controller 1 starts automatic parking. Based on this, in this embodiment, after the vehicle starts the automatic parking function, the parking controller 1 may continuously monitor whether the automatic parking instruction is received to confirm whether the vehicle is automatically parked, if the automatic parking instruction is received, it indicates that the vehicle is automatically parked, and after the automatic parking is completed, a scoring request is sent to the human-computer interaction terminal 2 for display, and when the user checks the scoring request, the user may correspondingly give a score. The human-computer interaction terminal 2 can be a central control large screen of a vehicle or a mobile terminal which establishes communication connection with the vehicle.
As a preferred embodiment, a scoring template may be configured in advance, where the scoring template includes a plurality of scoring items, and a user may score each scoring item separately and finally obtain a total score by summarizing. After the user scoring is completed, the human-computer interaction terminal 2 can send the user scoring including the scoring of each scoring item and the total scoring to the parking controller 1 for storage, so that effective data support is provided for the improvement of a subsequent automatic parking system.
As another preferred embodiment, the parking controller 1 is further remotely connected to a cloud server, and the parking controller 1 may further send the user score to the cloud server for storage, so as to avoid excessively occupying the storage space of the parking controller 1.
In a preferred embodiment of the present invention, as shown in fig. 2, when a user manually parks a vehicle, a parking controller obtains a parking difficulty score, a parking completion position score, and a parking fluency score within an effective parking period, and processes the parking difficulty score, the parking completion position score, and the parking fluency score to obtain a manual parking score and outputs the manual parking score;

In this embodiment, when a user manually parks a vehicle, the user may find that the vehicle cannot be parked due to the fact that an obstacle exists in the first parking space or the vehicle is difficult to park in the first parking space in the process of trying to park the vehicle in the first parking space, and at this time, the user may replace the second parking space to manually park the vehicle. If the second parking space is successfully parked at the moment, the user has two manual parking behaviors in the scene, and the corresponding manual parking behavior does not have scoring significance because the first parking space is not successfully parked. Therefore, when a user manually parks the vehicle, an effective parking time period needs to be determined, and then a parking difficulty score, a parking completion position score and a parking fluency score of a manual parking behavior corresponding to the effective parking time period are obtained, and further the manual parking score is obtained according to the parking difficulty score, the parking completion position score and the parking fluency score. After the manual parking is finished, the manual parking score is sent to the human-computer interaction terminal 2 to be displayed, a user can visually see the score result of the manual parking behavior of the user on the human-computer interaction terminal 2, and interaction entertainment of the vehicle is improved.
In a preferred embodiment of the present invention, the effective parking period is a period between the start time of manual parking and the end time of manual parking;

the manual parking start time is a time when the overlap area is last detected to be switched from 0 to non-0 before the manual parking end time.
Specifically, since the start of the manual parking by the user cannot be detected based on the subjective intention of the user, but the manual parking end time may be detected based on the position of the vehicle and the state of the vehicle, in the present embodiment, the manual parking end time is determined, and the manual parking start time is obtained based on the manual parking end time advancing manner.
Further specifically, when the vehicle continuously runs at a low speed and starts the automatic parking function, the user may select automatic parking or manual parking, so that the user can accurately identify the start time and the end time of the manual parking when selecting the manual parking, at this time, the image acquisition may be continuously performed by a camera mounted on the vehicle, the parking controller 1 obtains and stores the change of the overlapping area between the vehicle and the corresponding parking space based on the acquired image processing, and when it is detected that the proportion of the overlapping area to the total area of the parking spaces is not less than a preset value, the gear of the vehicle is in the P gear and the electronic parking brake system triggers activation to indicate that the manual parking is ended. Still taking the example that the parking in the first parking space fails and the parking in the second parking space succeeds, the user may engage the P gear when the parking in the second parking space succeeds, and then trigger and activate the electronic parking brake system, if the time is 10 hours and 05 minutes, by searching and storing the change condition of the overlap area before the time to the time, two times of switching the overlap area from 0 to non-0 may occur, one is the time of starting parking in the first parking space, such as 10 hours and 00 minutes, and the other is the time of starting parking in the second parking space, such as 10 hours and 03 minutes, then the 10 hours and 03 minutes are taken as the start time of manual parking, and the effective parking time period is 10 hours and 03 minutes to 10 hours and 05 minutes.
