Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
Referring to fig. 1, an active parking unlocking method based on an electronic fence according to an embodiment includes the following steps:
the cloud platform plans the electronic fence of the current vehicle, and the user stores the information of the electronic fence to the 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 is stored in a local vehicle machine or not;
if the current vehicle is in a starting state and the vehicle machine locally has electronic fence information, performing GPS real-time positioning, simultaneously acquiring a vehicle gear state, triggering the electronic fence until the vehicle end judges that the current vehicle drives into the range of the electronic fence and the vehicle gear is switched to a parking gear, and automatically unlocking a vehicle door; otherwise, the electronic fence is triggered.
According to the parking active unlocking method based on the electronic fence, a cloud platform customizes the 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 is within the range of the electronic fence; at the moment, 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. The invention can realize thousands of people and thousands of faces according to the actual situation of the user, brings better experience to the user, simultaneously ensures the safety of drivers and passengers, and exerts great advantages on the road sections which can block traffic.

Therefore, the electronic fence data are put in the local vehicle, rapid feedback can be made on vehicle behaviors, and the electronic fence data do not depend on remote services and have better tolerance on network stability, speed and the like.
The cloud platform recalibrates the electronic fence every month, updates the latest electronic fence range defined based on previous month data to the local vehicle machine, and covers the previous electronic fence data.
Therefore, the driving data and the GPS coordinate data of the user are extracted and calibrated again by taking the month as a unit, so that the electronic fence is more suitable for the real use condition of the user for using the vehicle.
When the electronic fence is implemented, firstly, in the daily driving process of a vehicle owner, a GPS module at the vehicle end can generate travel data of a vehicle, such as GPS coordinate data of a passing road, a parking spot, a starting flameout position and the like, then the data are transmitted back to a cloud platform of a vehicle factory through a wireless communication module configured at the vehicle end to be stored, in the beginning of each month, the cloud platform takes out the travel data and the GPS coordinate data of the last month of a user from a database, and carries out analysis, cleaning, analysis and excavation through an algorithm, then specific GPS coordinate data of a high-frequency parking spot of the user are extracted, in the calibration process, the algorithm rule is adopted to judge, an area range enriched with high-frequency parking spots is screened out, and an area range with overlarge dispersion degree is eliminated. After screening, a plurality of high-frequency parking point location enrichment area ranges exist, the cloud platform calculates the center coordinate (namely the center coordinate of the high-frequency parking point) of each area range, each center coordinate is locally optimal, and finally, a proper radius is assigned corresponding to each center coordinate, so that the electronic fence of a certain vehicle can be planned. The radius distance of the electronic fence is 100m under the default condition, the authority can be opened to the user, the radius parameters can be modified at the mobile end or the vehicle end to meet the vehicle using habit of the user, and even different radiuses of different electronic fences can be designated according to the road condition. And finally, after the electronic fence information of all vehicles is calculated in batch, the cloud platform distributes the electronic fence information of all vehicles through a network, accesses the wireless communication module of the vehicle end, updates the latest electronic fence range defined based on the last month data to the local vehicle machine and covers the previous version.
