Abstract

An apparatus and methods are provided for data communications associated with a vehicle. The apparatus preferably includes at least one electronic subsystem associated with the vehicle and a plurality of electrical conductors connected to the at least one electronic subsystem and associated with the vehicle. A vehicle data communications protocol converter is preferably connected to the plurality of electrical conductors for converting a first data communications protocol associated with data communications along the plurality of electrical conductors to a second data communications protocol such as a local-area infrared or an RF data communications protocol. The apparatus also preferably includes a transceiver connected to the data communications protocol converter for transmitting the second data communications protocol from the vehicle and receiving the data communications protocol from a remote data communications terminal or another portion of the vehicle.

Claims

1. A system for data communication associated with a vehicle, said system comprising:

a first data communications apparatus associated with the vehicle;

a second data communications apparatus associated with the vehicle;

at least one electrical conductor operatively interconnecting said first and second data communications apparatuses, said at least one electrical conductor comprising a data bus for transmitting data between said first and second data communications apparatuses;

a first data communications protocol adapted for transmitting vehicle data along said data bus;

means for converting said first data communications protocol to a second data communications protocol, said second data communications protocol adapted for transmitting vehicle data from said data bus to a remote data communications terminal.

2. A system according to claim 1, further comprising a connector connected to said at least one electrical conductor, a transceiver housing operatively connected to said connector, and wherein one of said first and second data communications apparatuses comprises a transceiver positioned within said transceiver housing.

3. A system according to claim 2, wherein said connector includes a plurality of pins having a predetermined pin configuration and first and second connector portions, wherein said connector has one of either a generally cylindrical or a generally rectangular shape, and wherein the second connector portion defines said transceiver housing.

4. A system according to claim 2, wherein said first and second data communications apparatuses are adapted to interface with at least one electronic subsystem associated with the vehicle and related to operation of the vehicle.

5. A system according to claim 2, wherein said transceiver includes a signal processing physical layer, and wherein said data communications protocol uses only the physical layer of said transceiver for signal processing.

6. A system according to claim 4, wherein said at least one electronic subsystem comprises an anti-locking brake system connected to the vehicle, and wherein said connector is operatively connected to said anti-locking brake system.
