Abstract

An add-on device and method for managing an electronic control unit (ECU) of a vehicle is disclosed. The add-on device includes a transceiver adapted for communicating with the communication network of a vehicle. The add-on device further includes a controller being communicatively connected to the transceiver, and adapted to generate a user-interface control signal addressed to the user interface of the vehicle, in order to manipulate the user interface of the vehicle and to present thereon command options prompting a user to enter a command selection in response to the command options presented. The controller is further adapted to receive the command selection from the user interface, and to generate in response thereto, an ECU control signal to be sent to the communication network for executing an operation with respect to a targeted ECU, in order to manage the targeted ECU from the user interface of the vehicle.

Claims

1. An add-on device for managing an electronic control unit (ECU) of a vehicle having one or more of said ECU, a communication network linked thereto for circulating data related to the one or more ECU, and a user interface being integrated in the vehicle and communicating with the communication network, the vehicle further having a vehicle interface communicating with the communication network, the add-on device comprising:

a transceiver adapted to cooperate with the vehicle interface for communicating with the communication network; and

a controller being communicatively connected to the transceiver, and adapted to generate a user-interface control signal addressed to said user interface, in order to manipulate the user interface of the vehicle and to present thereon command options prompting a user to enter a command selection in response thereto, the command selection being representative of an operation to be executed with respect to a targeted one of the one or more ECU, the controller being further adapted to receive the command selection from the user interface, and to generate in response thereto, an ECU control signal to be sent via the transceiver, to the communication network for executing said operation, in order to manage the targeted ECU from the user interface of the vehicle.

2. The add-on device according to claim 1, wherein the controller is adapted to receive feedback information from the communication network, the feedback information being related to said targeted one of the one or more ECU, the add-on device further comprising:

a memory being in communication with the controller for storing at least a portion of the feedback information.

3. The add-on device according to claim 1, in combination with the vehicle, wherein the user interface of the vehicle comprises at least one of:

an instrument cluster, a display screen, a control button, a touchscreen, a speaker and a microphone.

4. The add-on device according to claim 1, in combination with the vehicle, wherein the vehicle interface comprises an on-board diagnostics connection port and the add-on device comprises a corresponding OBD connector being connected to the transceiver.

5. The add-on device according to claim 1, in combination with the vehicle, wherein the vehicle interface comprises a wire connection with the communication network and the transceiver is connectable to said wire connection.

6. The add-on device according to claim 1, in combination with the vehicle, wherein the vehicle interface and the transceiver of the add-on device are adapted to communicate wirelessly.

7. The add-on device according to claim 1, in combination with the vehicle, wherein the communication network includes one or more interconnected data bus and wherein the add-on device comprises a transceiver for each of said one or more data bus.

8. A method for managing an electronic control unit (ECU) of a vehicle having one or more of said ECU, a communication network linked thereto for circulating data related to the one or more ECU, and a user interface integrated in the vehicle and communicating with the communication network, the vehicle further having a vehicle interface communicating with the communication network, the method comprising:

a) generating a user-interface control signal, by means of a controller in an add-on device, the user-interface control signal being addressed to the user interface of the vehicle in order to manipulate said user interface;

b) sending the user-interface control signal, by means of a transceiver communicatively connecting the controller with the vehicle interface, onto the communication network of the vehicle, in order to present on said user interface, command options prompting a user to enter a command selection in response thereto;

c) receiving the command selection, at the controller, via the communication network and vehicle interface, the command selection being representative of an operation to be executed with respect to a targeted one of the one or more ECU;

d) generating, by means of the controller, an ECU control signal in response to the command selection received; and

e) sending the ECU control signal, by means of the transceiver, to the communication network for executing said operation, in order to manage the targeted ECU from the user interface of the vehicle.

9. The method according to claim 8, further comprising, prior to step (a):

receiving, at the controller, an activation command from the user interface, said activation command instructing activation of the add-on device.

10. The method according to claim 8, further comprising, prior to step (a):

retrieving vehicle information from the communication network; and

validating said vehicle information, by means of the controller, based on one or more validation rule in order to activate the add-on device.

11. The method according to claim 8, wherein the operation of step (e) comprises at least one of:

reading status information on the communication network concerning the targeted one of the one or more ECU;

retrieving data from the targeted one of the one or more ECU;

pushing data to said targeted one of the one or more ECU; and

performing an operation on said targeted one of the one or more ECU.

12. The method according to claim 8 further comprising, after step (e):

at the controller, receiving feedback data from said targeted one of the one or more ECU, via the transceiver, in response to the executed operation;

generating a feedback message, by means of the controller, said feedback message being addressed to the user interface of the vehicle; and

sending the feedback message, via the transceiver and the communication network, to the user interface of the vehicle to present thereon the feedback message.

13. The method according to claim 12, further comprising:

storing the feedback data in a memory.

14. The method according claim 13, further comprising:

reading the feedback data stored in the memory, by means of the controller;

generating a report message including at least a portion of the stored feedback data;

sending the report message, via the transceiver and the communication network, to the user interface of the vehicle to present thereon said report message.

15. A non-transitory processor-readable storage medium for managing an electronic control unit (ECU) of a vehicle having one or more of said ECU, a communication network linked thereto for circulating data related to the one or more ECU, and a user interface integrated in the vehicle and communicating with the communication network, the vehicle further having a vehicle interface communicating with the communication network, the processor-readable storage medium comprising data and instructions for execution by a controller in an add-on device to:

a) generate a user-interface control signal being addressed to the user interface of the vehicle in order to manipulate said user interface;

b) send the user-interface control signal, by means of a transceiver communicatively connecting the controller with the vehicle interface, onto the communication network of the vehicle, in order to present on said user interface, command options prompting a user to enter a command selection in response thereto;
