Background
With the continuous increase of the personal automobile conservation amount of residents, mobile intelligent terminals are becoming more popular today with advanced digitalization, the use frequency and the scene of mobile phones and intelligent wearing equipment are becoming higher, and the intelligent requirements of people on various articles in life are becoming higher. The technology of the vehicle digital key provides more functions than the traditional key, can have higher user experience, and basically removes the dependence on the entity key. The acceptance and use of digital keys are also increasing. And as mobile phone manufacturers have continuously adapting and supporting protocol specifications based on vehicle keys, a plurality of digital key protocols mainly appear in China, wherein the digital key protocols are CCC (Car Connectivity Consortium, CCC for short), ICCE (Intelligent Car Connectivity Ecosystem, ICCE for short) and ICDOA (Intelligent Car Connectivity Open Alliance, ICDOA for short).
As a role of a car factory while the digital key increasingly pursues experience-limited convenience, it is necessary to support various mainstream standard key protocols and general key protocols unrelated to the mobile phone without knowing the mobile phone used by the user in advance and without being compatible with each other by various alliances. If a mobile phone supports multiple protocols at the same time or the standard protocol has insufficient supporting functions, a user can hardly make a judgment when using a digital key for the first time and the information quantity is insufficient to decide which key to use. And the mobile phone/automobile supports a certain digital key protocol, which is supported by a protocol main body, and is likely to be caused by the condition that partial functions in the digital key protocol are not fully supported due to the differences of hardware, software and regulations, and the information can only be obtained by manual evaluation after testing by a mobile phone factory of a vehicle factory. Therefore, a selection strategy with a key agreement is needed for the vehicle itself to help the user obtain a better digital key usage experience. Especially when the vehicle and the handset support multiple key agreements.

Some single function score, such as NFC, is calculated: degree of automobile support: 1 multiplied by the mobile phone support 1 and then multiplied by the function weight 80, the weight can be calibrated from the function importance and the mobile phone factory function completion. A score of 1×1×80=80 is obtained. The door lock control score was recalculated 0.5×1×60=30.

As shown in fig. 3, in another exemplary embodiment of the present application, the present application further provides a digital key recommendation method, including the following steps:
step S1: the mobile phone factory wallet guides the user to start vehicle key initialization.
Step S2: the user selects a vehicle brand for key matching.
Step S3: checking whether the mobile phone can be connected or not, if so, updating the latest version of the SDK from the official network, and if not, proceeding to step S5, and using the locally preset dynamic library file.
Step S4: and checking whether the dynamic library is updated according to the vehicle type, and if so, providing the dynamic library for the wallet APP to download.
Step S5: and dynamically loading a local dynamic library so file.
Step S6: the SDK is used for scanning the Bluetooth device of the vehicle.
Step S7: and carrying out Bluetooth connection and creating a secure channel. If the connection is successful, the process proceeds to step S8, and if it is failed, the process proceeds to step S20.
Step S8: the dynamic library calls back to the wallet, and the wallet supports the digital key agreement. Step S9 is entered.
Step S9: the dynamic library performs key creation negotiation of the application layer, and the supporting information of the transfer protocol goes to step S10.
Step S10: and trying to connect the cloud end of the vehicle enterprise to inquire whether a new version is pushed. The connection proceeds to step S11 successfully, and if the network is not available, the process proceeds to step S13.
Step S11: and checking whether the version number of the vehicle end is matched with the version number of the same vehicle type in the cloud. If so, the process proceeds to step S13. If not, the process proceeds to step S12.
Step S12: and pushing the new version to the vehicle end, and ending the key recommendation flow. And redirecting to conduct key recommendation after version updating.
Step S13: and when no new version exists. Comparing whether the mobile phone support protocol has intersection or not, if not, the vehicle end proceeds to step S14. Otherwise, the process advances to step S15.
Step S14: and (5) recommending the user to use the private key of the vehicle manufacturer without a standard protocol supported at the same time, guiding the downloading vehicle manufacturer APP, and entering step S20 to finish the key recommending process.
Step S15: according to intersection a of the two end support protocols. And transmitting the capability set information of all the protocols in the A to the mobile phone terminal. And transmitting json data form of the support degree of the vehicle factory protocol. The vehicle factory protocol support is shown in table 1 below. In table 1, from 0 to 1, the degree of support is higher as the degree of support approaches 1 from unsupported to fully supported.
TABLE 1 vehicle factory protocol support Table
Step S16: the SDK dynamic library triggers a callback to require the wallet to provide a functional support case table for the corresponding protocol. Proceed to S17. The handset protocol support is shown in table 2 below. In table 2, the support is 1, and the support is not 0.
Table 2 handset protocol support table
Step S17: it was checked whether there was a vehicle unsupported and a score was calculated according to the scoring evaluation rules based on the data of tables 1 and 2. Calculating a score: single function item score: p=i×j×k …; total recommendation score:
(function 1) +p (function 2) + …, and after the result, proceed to S18. For example: the car and handset support both ICCE and CCC protocols, and decisions need to be made in these 2 protocols. And calculating a recommendation score of the CCC protocol, namely the sum of the scores of the functions. Some single function score, such as NFC, is calculated: degree of automobile support: 1 multiplied by the mobile phone support 1 and then multiplied by the function weight 80, the weight can be calibrated from the function importance and the mobile phone factory function completion. A score of 1×1×80=80 is obtained. The door lock control score was recalculated 0.5×1×60=30. And similarly, calculating all the function item scores to obtain the recommendation degree of a certain protocol. A score of 0 is not supporting this function.
