Abstract

A system for processing information relating to a vehicle includes one or more electronic control units which can be connected to one another through a vehicle network. The system includes an electronic control device adapted to interface to and exchange data with the network and a nomadic device adapted to exchange data with the electronic device, wherein the electronic control device includes an automatic configuration module adapted to automatically detect parameters of the network so as to retrieve a network database of the vehicle. The network database includes the information required for properly interpreting the data circulating in the network.

Claims

1. A system for processing information relating to a vehicle that includes one or more electronic control units which can be connected to one another through a vehicle network, said system comprising:

an electronic control device adapted to interface to and exchange data with said vehicle network;

a nomadic device adapted to exchange data with said electronic control device; and

memory means associated to said nomadic device for storing a network database of said vehicle network, said network database comprising information required for the nomadic device to properly interpret data circulating in said vehicle network and exchanged with said electronic control device and said nomadic device.

2. The system according to claim 1, wherein said network database is formed by a plurality of messages having a unique identification number compliant with a CAN standard and including a data field consisting of information related to signals able to be interpreted by said vehicle network.

3. The system according to claim 1, wherein said electronic control device comprises an automatic configuration module adapted to automatically detect parameters of said vehicle network so as to retrieve said network database of said vehicle.

4. The system according to claim 3, wherein said nomadic device comprises means for transmitting said parameters to a remote server adapted to exchange data with said nomadic device through a communication network, said remote server comprising a data processing module adapted to analyse said parameters in order to retrieve said network database of said vehicle from a network database library and means for transmitting to said nomadic device said network database.

5. The system according to claim 4, wherein said remote server further comprises an authentication management module for managing the authorisation levels required for gaining access to said electronic control units through said nomadic device.

6. The system according to claim 1, wherein said nomadic device and said electronic control device comprise respective encrypting/decrypting modules which allow them to exchange data in an encrypted manner.

7. The system according to claim 1, wherein said nomadic device comprises a user interface on which data received from said electronic control units can be represented in a user-defined manner.

8. The system according to claim 1, wherein said electronic control device comprises a physical signal interface adapted to drive physical signals of said electronic control units through said nomadic device and to receive real-time information about the input state of said physical signals.

9. The system according to claim 1, wherein said electronic control device comprises an electronic card which can be installed in said vehicle for interfacing to said vehicle network.

10. The system according to claim 1, wherein said electronic control device can be integrated with an existing element of said vehicle, in particular an instrument panel or an infotainment control unit, thus becoming an integral part of said element.

11. The system according to claim 1, wherein said control device comprises a graphic interface which is reconfigured on the basis of the vehicle network parameters of said vehicle, of information received from sensors of said nomadic device, and of information received in real time.

12. A method for processing information relating to a vehicle that includes one or more electronic control units which can be connected to one another through a vehicle network, said method comprising the steps of:

prearranging an electronic control device adapted to interface to and exchange data with said vehicle network;

prearranging a nomadic device adapted to exchange data with said electronic control device, and

associating memory means to said nomadic device for storing a network database of said vehicle network, said network database comprising information required for properly interpreting data circulating in said vehicle network and exchanged with said electronic control device and said nomadic device.

13. The method according to claim 12, wherein said electronic control device is adapted to automatically detect parameters of said vehicle network so as to retrieve said network database of said vehicle.

14. The method according to claim 13, wherein said nomadic device transmits said parameters to a remote server adapted to exchange data with said nomadic device through a communication network, said remote server analyses said parameters in order to retrieve said network database of said vehicle from a network database library and transmits said network database to said nomadic device.

15. The method according to claim 14, wherein, if said network database is not included in said network database library, a notice is sent to the administrator of said remote server.

16. The method according to claim 15, wherein if signals coming from said electronic control units comprise information about a malfunction of at least one of said electronic control units of said vehicle, an information comprising a specific warning can be displayed on said nomadic device.

17. The method according to claim 16, wherein a service call is automatically made through the nomadic device to the remote server or to a service centre, during which call the data traffic generated by the vehicle network in relation to said malfunction is sent as well.

18. The method according to claim 16, wherein, in the event of an accident, an emergency call is automatically made through the nomadic device to default emergency telephone numbers or to telephone numbers set beforehand by the user in the nomadic device, said accident being detected upon reception by the nomadic device of specific signals from the vehicle network, such as, for example, a message indicating that one or more airbags have deployed.

19. The method according to claim 14, wherein said remote server, when an update is available, establishes a “

push”

type communication with said nomadic device, and/or said nomadic device, when it is connected to a new vehicle, establishes a “

pull”

type communication with said remote server through the electronic control device.

20. The method according to claim 15, wherein said remote server, when an update is available, establishes a “

push”

type communication with said nomadic device, and/or said nomadic device, when it is connected to a new vehicle, establishes a “

pull”

type communication with said remote server through the electronic control device.

21. A computer product which can be loaded into the memory of a nomadic device for processing information relating to a vehicle comprising one or more electronic control units which can be connected to one another through a vehicle network, said computer product comprising software code portions for implementing the method according to claim 12 when the computer product is executed in said nomadic device.
