Abstract

Method of providing services for a vehicle, the method comprising: storing for at least one model of vehicle of said group of vehicles, the configuration files for at least one service to be provided; storing a set of data pairs comprising an identifier of the control unit and an identification number of the corresponding vehicle; receiving the identification number of the vehicle from said vehicle by the services provision server; extracting the identifier of the control unit as a function of the identification number of the vehicle; an extraction of one or more configuration files as a function of a vehicle identification datum; and a downloading by the control unit of said vehicle from the services provision server of the configuration file or files extracted for the setting up of the service or services to be provided for the model of the vehicle.

Claims

1. A method of providing services for a vehicle of a group of vehicles of various models, comprising a step of placing a control unit (TCU_unit), onboard said vehicle, in communication with an offboard services provision server (GDC), characterized in that the method comprises:

a first storage (33) for at least one model of vehicle of said group of vehicles, of the configuration files for at least one service to be provided;

a second storage (43) of a set of data pairs comprising an identifier of the control unit (TCU_unit) and an identification number of the vehicle (VIN) corresponding thereto;

a reception of the identification number (2) of the vehicle (VIN) from said vehicle by the services provision server (GDC);

an extraction (3) of the identifier of the control unit (TCU_unit) as a function of the identification number of the vehicle (VIN);

an extraction (4) of one or more configuration files as a function of an identification datum of the vehicle (VIN); and

a downloading (9) by the control unit (TCU_unit) of said vehicle from the services provision server (GDC) of the configuration file or files extracted for the deploying of the service or services to be provided for the model of the vehicle.

2. The method as claimed in claim 1, comprising:

a transmission (5) of an order for activation from the services provision server (GDC) to the control unit (TCU_unit); and

a making available (8) by the services provision server for downloading by the control unit of the configuration files extracted.

3. The method as claimed in claim 1, comprising a step of dispatching an activation message (2) from an activation server (CMCIAL) to the services provision server (GDC) so as to activate or deactivate the services of the services provision server (GDC) provided to said vehicle.

4. The method as claimed in claim 1, comprising:

a processing step (62) in the course of which the control unit (TCU_unit) processes service data flowing on communication buses of the vehicle (CAN-V, CAN-M) as a function of the configuration files downloaded by the control unit (TCU_unit);

a step (63) of storing the service data processed in storage means (STOCK2);

a step (64) of verifying the realization of conditions of transmission of the stored service data; and

a step (65) of transmitting the stored service data from the control unit (TCU_unit) to the services provision server (GDC) when the transmission conditions are realized.

5. The method as claimed in claim 4, comprising a step of transmission (69) in the course of which the service data received by the services provision server (GDC) are transmitted per service and per client of the services provision server (GDC) to a server for storing the client data (CLT).

6. A system for providing services for a vehicle of a group of vehicles of various models, said system comprising:

an offboard server for providing services for the vehicle (GDC);

a control unit (TCU_unit) onboard the vehicle for collecting data for the provision of services; and

first communication means for allowing a communication between the control unit (TCU_unit) and the services provision server (GDC);

characterized in that the services provision server (GDC) is linked to first storage means (MSI) configured to store the configuration files for at least one service to be provided for at least one model of vehicle of said group and to second storage means (MS2) configured to store a set of data pairs comprising an identifier of the control unit (TCU_unit) and an identification number of the vehicle (VIN) corresponding thereto, and comprises extraction means (ME) configured to extract within the second storage means (MS2), the identifier of the control unit (TCU_unit) on the basis of the identification number of the vehicle (VIN) and configured to extract from the first storage means (MSI) as a function of an identification datum of the vehicle (VIN), one or more configuration files,

and in that the control unit is configured to download from the services provision server (GDC) the configuration file or files extracted for the deploying of the service or services to be provided for the model of the vehicle.

7. The system as claimed in claim 6, comprising an activation server (CMCIAL) remote from said vehicle, second communication means for allowing a communication between the activation server (CMCIAL) and the services provision server (GDC), said activation server (CMCIAL) is configured to dispatch an activation message to the services provision server (GDC) so as to activate or deactivate the services of the services provision server (GDC) of services provided to said vehicle.

8. The system as claimed in claim 6, in which the onboard control unit (TCU_unit) comprises means of storage (STOCK1) of a security certificate (CS), said security certificate comprising the unique identifier of the control unit (TCU_unit) and the system comprises a security server (SCRT) remote from said vehicle, configured to authenticate the control unit on the basis of its security certificate (CS) and to establish an encrypted communication between the control unit (TCU_unit) and the services provision server (GDC) using the security certificate (CS) of the control unit (TCU_unit).

9. The system as claimed in claim 6, in which the onboard control unit (TCU_unit) comprises processing means (CAN_int) for processing service data flowing on the communication buses of the vehicle (CAN-V, CAN-M) as a function of the configuration files downloaded by the control unit (TCU_unit), storage means (STOCK2) for storing the processed service data and management means (GEST) configured to verify the realization of transmission conditions, said control unit (TCU_unit) being configured to transmit the stored service data to the services provision server (GDC) when the transmission conditions are realized.
