Abstract

An apparatus and methods are provided for a pass-through dongle for accessing and interacting with vehicle performance and status data. The dongle includes a first connector for plugging into an OBD-II connector of a vehicle. A wireless connection may be established between the dongle and a mobile device that provides access to and interactivity with the vehicle performance and status data. A second connector comprising the dongle is configured to receive an auxiliary device that is configured to access vehicle status data by way of the OBD-II connection. The dongle simultaneously establishes the wireless connection with the mobile device and provides the auxiliary device with access to the vehicle performance and status data. In some embodiments, the dongle is configured to operate in conjunction with a vehicle diagnostic communication system that includes a vehicle performance system whereby the vehicle performance and status data may be interactively accessed.

First claim

What is claimed is:

1. A dongle for connecting to an OBD-II connector of a vehicle, the dongle comprising:
a female connector for plugging into the OBD-II connector, wherein the female connector includes a multiplicity of male pins that are in electrical communication with the circuitry such that the vehicle status data may be transmitted from the OBD-II connector to the circuitry;
a male connector for receiving an auxiliary device whereby the auxiliary device may be connected to the dongle by way of the male connector while simultaneously being connected to a wireless device;
circuitry for accessing vehicle status data;
a wireless scan tool configured to provide performance and status data regarding the vehicle;
a wireless transceiver for wirelessly connecting to a mobile device to provide the mobile device with access to a vehicle performance system and interactivity with vehicle performance and status data;
a rigid body for housing the circuitry; and
wherein the dongle is configured to wirelessly access at least one of an engine RPM, vehicle speed, coolant temperature, air flow, manifold pressure, barometric pressure, ambient air temperature, and boost pressure of the vehicle.

2. The dongle of claim 1 , wherein the male connector includes a multiplicity of female connectors suitable for receiving pins comprising any of various devices that are compatible with the OBD-II connector of the vehicle.

3. The dongle of claim 2 , wherein the multiplicity of female connectors are in electrical communication with the circuitry such that electrical signals may be transmitted from the OBD-II connector of the vehicle to the auxiliary device.

4. The dongle of claim 1 , wherein the dongle is configured to be plugged into the OBD-II connector to access vehicle status data and pass the vehicle status data to the auxiliary device by way of the male connector.

5. The dongle of claim 4 , wherein the dongle is configured to wirelessly transmit the vehicle status data to a device or system that is configured to read and display the vehicle status data to an end-user of the dongle.

6. The dongle of claim 1 , wherein the dongle is configured to operate in conjunction with a vehicle diagnostic communication system that includes a vehicle performance system.

7. The dongle of claim 6 , wherein the vehicle performance system comprises a mobile device application operating on a mobile device.

8. The dongle of claim 7 , wherein the dongle is configured to plug into the OBD-II connector and establish a wireless connection with the mobile device whereby the vehicle performance system provides access and interactivity to vehicle performance and status data.

9. The dongle of claim 8 , wherein the dongle is configured to provide the auxiliary device with access to the vehicle performance and status data.

10. The dongle of claim 8 , wherein the auxiliary device comprises any device configured to access vehicle status data by way of an OBD-II connection.

11. The dongle of claim 10 , wherein the dongle is configured to simultaneously establish the wireless connection with the mobile device and provide the auxiliary device with access to the vehicle performance and status data.

12. A method for accessing vehicle status data, comprising:
plugging a first connector of a pass-through dongle into an OBD-II connector of a vehicle;
establishing a wireless connection between the pass-through dongle and a mobile device for wirelessly providing the mobile device with access to a vehicle performance system and interactivity with vehicle performance and status data;
plugging a second connector of the pass-through dongle into an auxiliary device; and
wherein the dongle is configured to wirelessly access at least one of an engine RPM, vehicle speed, coolant temperature, air flow, manifold pressure, barometric pressure, ambient air temperature, and boost pressure of the vehicle.

13. The method of claim 12 , wherein establishing the wireless connection includes accessing and interacting with the vehicle status data by way of the mobile device.

14. The method of claim 13 , wherein plugging the second connector includes accessing the vehicle status data by way of the auxiliary device.

15. A method for a dongle for accessing vehicle status data, comprising:
configuring circuitry to receive the vehicle status data;
housing the circuitry within a rigid body having a first connector and a second connector;
adapting the first connector to plug into an OBD-II connector of a vehicle;
configuring the second connector to plug into an auxiliary device;
providing a wireless scan tool configured to provide performance and status data regarding the vehicle;
coupling the circuitry with the first connector and the second connector; and
establishing a connection between an auxiliary device with the dongle by way of the second connector while simultaneously being connected to a wireless device by providing a wireless connection between the dongle and a mobile device wherein the dongle is configured to wirelessly access at least one of an engine RPM, vehicle speed, coolant temperature, air flow, manifold pressure, barometric pressure, ambient air temperature, and boost pressure of the vehicle.

16. The method of claim 15 , wherein configuring the circuitry includes configuring the circuitry to operate in conjunction with a vehicle diagnostic communication system that includes a vehicle performance system.

17. The method of claim 16 , wherein configuring the circuitry includes configuring the circuitry to establish a wireless connection with a mobile device that provides access to and interactivity with the vehicle performance and status data.

18. The method of claim 17 , wherein configuring the second connector includes configuring the circuitry to provide the auxiliary device with access to the vehicle status data.

19. The method of claim 18 , wherein coupling the circuitry includes configuring the circuitry to simultaneously establish the wireless connection with the mobile device and provide the auxiliary device with access to the vehicle status data.
