- Verifying the user's subscription information consists, for example, of ensuring that the user's means of payment (user's account balance, bank card number, etc.) are valid, or that certain conditions for borrowing a vehicle are met (for example the maximum number of borrowings authorized or a maximum authorized mileage has not yet been reached by the user).
- the reference makes it possible to identify the user's subscription from among all the subscriptions for which information is stored in the database 31 of the server 30.
- the control unit 43 of the vehicle 40 sends for example a command to deactivate an anti-theft device of the vehicle 40.
- the anti-theft device is for example configured to block the steering column of the vehicle 40 when it is activated.
- the proposed solution is thus simpler to implement because it does not require establishing communication between the terminal 50 and the server 30.
- the proposed solution is potentially less costly for the user, especially if the user is roaming in a foreign country. Indeed, when a free ad-hoc communication link 61 which does not use an infrastructure is used between the terminal 50 and the vehicle 40, the user has no communication cost to assume. The cost linked to the communication link 71 between the vehicle 40 and the server 30 can in fact be borne by the manager of the vehicle sharing service.
- FIG. 5 schematically represents the main steps of a method 100 for accessing a vehicle 40 of a vehicle sharing system 20 according to the invention.
- the various steps of this method 100 are for example implemented by the server 30, the vehicle 40 and the terminal 50 of the vehicle sharing system 20 described above with reference to FIG. 2.
- the method 100 comprises in particular the following steps:
- an identification 101 of the vehicle 40 by the terminal 50 from a local database 52 of the terminal 50, said local database 52 comprising a list of vehicles likely to be used by the user and, for each vehicle 40 of the list, information making it possible to establish a communication between said vehicle 40 and the terminal 50 on the first communication link 61,
- the method 100 can also include a transmission by the vehicle 40 of a confirmation to the terminal 50 if access to the vehicle is authorized. This step is not essential, however, since an indication that access to the vehicle is authorized can be visible directly on the vehicle. This step is not shown in Figure 5.
- the identification 101 of the vehicle 40 by the terminal 50 from the local database 52 of the terminal 50 is carried out in a manner autonomous by the terminal, without there being an interaction between the terminal 50 and a remote server.
- the method 100 further comprises a preliminary step of loading on the terminal 50 of the local database 52.
- the local database 52 can store the list of all the vehicles of the sharing service. vehicles, regardless of the geographical position of the vehicles.
- the local database 52 can be associated with a particular geographical area in which the vehicles of the list stored in the local database 52 are located, and in which the user plans to go.
- a message sequence diagram 200 representing an example of a sequence of steps in a method 100 for accessing a vehicle 40 of a vehicle sharing system 20 according to the invention is illustrated in FIG. 6.
- an identification message 201 is for example sent repeatedly by the vehicle 40 to a terminal 50 of a user of the car-sharing service.
- the identification message 201 contains in particular an identifier of the vehicle 40.
- the terminal 50 decodes the identification message 201, and if a vehicle associated with the identifier contained in the identification message 201 is found in the local database 52 of the terminal 50 (identification step 101), the terminal 50 sends an authentication message 202 to the vehicle 40.
- the authentication message 202 contains for example an authentication key associated with the vehicle 40 identified and stored in the local database 52.
- the vehicle 40 verifies the authentication key and, if the verification is successful, it sends an authentication confirmation message 203 (the set formed by the authentication message 202 and the authentication confirmation message 203 corresponds to the 'pairing step 102 between the terminal 50 and the vehicle 40).
- the terminal 50 is then able to send the vehicle 40 a message 204 access request containing a reference to the user's subscription to the vehicle sharing service (issuing step 103).
- the vehicle 40 then transmits said reference to the server 30 in a new access request message 205 addressed to the server 30 (transmission step 104).
- the server 30 verifies the user's subscription information stored in the database 31 of the server 30 (verification step 105) from the transmitted reference. If the verification is successful, the server 30 sends a message 206 for authorization of access to the vehicle 40 (sending step 106). Receipt of the access authorization message 206 triggers the unlocking of an anti-theft system of the vehicle 40.
- vehicle 40 can send a confirmation message to terminal 50 if access to the vehicle is permitted. This message is not shown in Figure 6.
- the messages 201, 202, 203 and 204 exchanged between the terminal 50 and the vehicle 40 are exchanged on the first communication link 61.
- the messages 205 and 206 exchanged between the vehicle 40 and the server 30 are exchanged over the second communication link 71.
- the procedure for accessing a vehicle of a car-sharing service proposed by the invention is both simple and advantageous in terms of communication cost for a user.
