Referring to fig. 1, an active parking unlocking method based on an electronic fence in an embodiment includes the following steps:
the cloud platform plans an electronic fence of the current vehicle, and a user stores information of the electronic fence to a local vehicle machine;
the method comprises the steps that a vehicle end obtains the starting state of a current vehicle and whether electronic fence information exists locally in a vehicle machine;
if the current vehicle is in a starting state and the electronic fence information exists in the vehicle machine locally, GPS real-time positioning is carried out, meanwhile, the vehicle gear state is acquired, the electronic fence is triggered until the vehicle end judges that the current vehicle enters the range of the electronic fence and the vehicle gear is switched to a parking gear, and the vehicle door is automatically unlocked; and otherwise, ending triggering the electronic fence.
According to the parking active unlocking method based on the electronic fence, the cloud platform is used for customizing an electronic fence for a vehicle based on GPS data of a daily vehicle of a vehicle owner, and the electronic fence is triggered when the vehicle appears in the range of the electronic fence; at this time, if the vehicle is in a starting state and the gear is switched to a parking gear, the vehicle can be automatically unlocked, and a driver and a passenger can get on or off the vehicle in time only by directly pulling the vehicle door once.

Therefore, the driving data and GPS coordinate data of the user are re-extracted and calibrated by taking the month as a unit, so that the electronic fence is more suitable for the actual use condition of the vehicle of the user.
When the method is implemented, an electronic fence is planned, firstly, a GPS module at a vehicle end generates travel data of a vehicle in the daily driving process of a vehicle owner, such as GPS coordinate data of a position for starting flameout through a road and a parking spot, and then the data are transmitted back to a cloud platform of a vehicle factory for storage through a wireless communication module configured at the vehicle end, the cloud platform takes out the travel data and the GPS coordinate data of a user in the last month from a database at the beginning of each month, analyzes, cleans, analyzes and excavates the travel data through an algorithm, then extracts specific GPS coordinate data of a high-frequency parking spot of the user, and in the calibration process, the area range for gathering the high-frequency parking spot point positions is screened through algorithm rule judgment, and the area range with overlarge dispersion is eliminated. After screening, a plurality of high-frequency parking point position enriched area ranges exist, the cloud platform calculates center coordinates of each area range (namely, the center coordinates of the high-frequency parking points), each center coordinate locally reaches the optimum, and finally, an appropriate radius is designated corresponding to each center coordinate, so that an electronic fence of a certain vehicle can be planned. Under the default condition, the radius distance of the electronic fence is 100m, and certainly, the authority can be opened for a user, the radius parameters can be modified at the mobile end or the vehicle-machine end so as to meet the habit of self-use, and even different radiuses of different electronic fences can be designated according to the road condition. Finally, after the electronic fence information of all the vehicles is calculated in batches, the cloud platform distributes the electronic fence information of each vehicle through a network, accesses a wireless communication module at a vehicle end, updates the latest electronic fence range defined based on the previous month data to the local of the vehicle and covers the previous version.
