Abstract

An interface/electronics module for reading information from a vehicle data bus and controlling functions available through the vehicle data bus. A graphical user interface is provided. The interface may include a stand-alone tablet computer or may be part of an integrated and permanently-mounted display. The interface/electronics module may include the functionality of the factory audio system (such as a radio tuner, power amplifier, etc.). In addition, the interface/electronics module is able to transmit commands via the vehicle's CAN bus.

First claim

Having described our invention, we claim:

1. An aftermarket vehicle information and control interface method configured for use on a vehicle originally having a factory radio, a plurality of speakers, a CAN bus operating in a particular CAN message format, and a plurality of OEM components connected to said CAN bus, said OEM components being responsive to commands transmitted via said CAN bus, comprising:
(a) removing said factory radio from said vehicle;
(b) installing an interface/electronics module, including,
(i) a processor,
(ii) an associated memory,
(iii) a power amplifier,
(iv) said interface/electronics module being configured to receive a signal from an audio source, amplify said signal and transmit said signal to said plurality of speakers;

(c) providing a tablet that is housed separately from said interface/electronics module, said tablet including a touchscreen;
(d) using said tablet to display messages and receive inputs suitable for the control of said interface/electronics module;
(e) said tablet being connected to said electronics/interface module so that user inputs made to said tablet can control operations of said electronics/interface module;
(f) said tablet and said interface/electronics module in combination being configured to replace said factory radio;
(g) loading said particular CAN message format in said associated memory;
(h) said interface/electronics module using said particular CAN message format to read messages on said CAN bus and send said read messages to said tablet for display in a user-readable format on said tablet; and
(i) said tablet receiving a user selection by said touchscreen and said interface/electronics module creating a CAN message in said particular CAN message format responsive to said user selection and placing said responsive CAN signal on said CAN bus, thereby commanding one of said OEM components to act.

2. The aftermarket vehicle information and control interface method as recited in claim 1 , wherein said connection between said tablet and said interface/electronics module is a hardwired connection.

3. The aftermarket vehicle information and control interface method as recited in claim 1 , wherein said connection between said tablet and said interface/electronics module is a wireless connection.

4. The aftermarket vehicle information and control interface method as recited in claim 1 , wherein said tablet is mounted in a tablet receiver in a location formerly occupied by said factory radio.

5. The aftermarket vehicle information and control interface method as recited in claim 1 , further comprising selecting said CAN message format from among a plurality of available CAN message formats.

6. The aftermarket vehicle information and control interface method as recited in claim 4 , further comprising providing a fascia surrounding said tablet receiver, said fascia blending smoothly into a dash of said vehicle.

7. The aftermarket vehicle information and control interface method as recited in claim 1 , wherein said interface/electronics module further comprises non-CAN inputs.

8. The aftermarket vehicle information and control interface method as recited in claim 1 , wherein said interface/electronics module reads an engine parameter from said CAN bus and displays said engine parameter on said touch screen.

9. The aftermarket vehicle information and control interface method as recited in claim 1 , wherein said associated memory stores a set of custom settings for a particular user.

10. The aftermarket vehicle information and control interface method as recited in claim 1 , wherein said associated memory stores multiple sets of custom settings for multiple users.

11. An aftermarket vehicle information and control interface method configured for use on a vehicle originally having a factory radio, a plurality of speakers, a CAN bus operating in a particular CAN message format, and a plurality of OEM components connected to said CAN bus, said OEM components being responsive to commands transmitted via said CAN bus, comprising:
(a) removing said factory radio from said vehicle;
(b) installing an interface/electronics module in said vehicle, including,
(i) a processor,
(ii) an associated memory
(iii) a radio frequency tuner configured to received broadcasts and provide an audio source;
(iv) said interface/electronics module being configured to receive a signal from said audio source, amplify said signal and transmit said signal to said plurality of speakers;

(c) providing a tablet that is located apart from said interface/electronics module, said tablet including a touchscreen;
(d) said tablet including a touchscreen display configured to display messages and receive user inputs suitable for the control of said interface/electronics module;
(e) said tablet being connected to said electronics/interface module so that user inputs made to said tablet can control operations of said electronics/interface module;
(f) loading said particular CAN message format in said associated memory;
(g) connecting said interface/electronics module to said vehicle CAN bus;
(h) said tablet displaying a user-readable messages based on a CAN bus message that is read by said interface/electronics module;
(i) said tablet receiving a user selection by said touchscreen and sending said user selection to said interface/electronics module; and
(j) said interface/electronics module then creating a CAN message in said particular CAN message format responsive to said user selection and placing said responsive CAN message on said CAN bus, thereby commanding one of said OEM components to act.

12. The aftermarket vehicle information and control interface method as recited in claim 11 , wherein said connection between said tablet and said interface/electronics module is a hardwired connection.

13. The aftermarket vehicle information and control interface method as recited in claim 11 , wherein said connection between said tablet and said interface/electronics module is a wireless connection.

14. The aftermarket vehicle information and control interface method as recited in claim 11 , wherein said tablet is mounted in a tablet receiver in a location formerly occupied by said factory radio.

15. The aftermarket vehicle information and control interface method as recited in claim 11 , further comprising selecting said CAN message format from among a plurality of available CAN message formats.

16. The aftermarket vehicle information and control interface method as recited in claim 14 , further comprising providing a fascia surrounding said tablet receiver, said fascia blending smoothly into a dash of said vehicle.

17. The aftermarket vehicle information and control interface method as recited in claim 11 , wherein said interface/electronics module further comprises non-CAN inputs.

18. The aftermarket vehicle information and control interface method as recited in claim 11 , wherein said interface/electronics module reads an engine parameter from said CAN bus and displays said engine parameter on said touch screen.

19. The aftermarket vehicle information and control interface method as recited in claim 11 , wherein said associated memory stores a set of custom settings for a particular user.

20. The aftermarket vehicle information and control interface method as recited in claim 11 , wherein said associated memory stored multiple sets of custom settings for multiple users.
