Abstract

Systems and methods for communicating a signal over a hydraulic line in a vehicle are provided. In one embodiment, a system can include a hydraulic line. The hydraulic line can include at least one communication medium for propagating a communication signal. The system can also include at least one signal communication device configured to receive the communication signal communicated over the hydraulic line. The system can also include at least one vehicle component in communication with the at least one signal communication device.

First claim

What is claimed is:

1. A system for communicating a signal in a vehicle, the system comprising:
an electrically conductive hydraulic line electrically coupled to a common ground;
a set of transducers,
wherein a first transducer from the set of transducers includes a sonic sensor and a sonic transmitter to configure the first transducer to, respectively, sense or transmit the signal through the electrically conductive hydraulic line;
at least one medium for propagating the signal wirelessly;
wherein a second transducer of the set of the set of transducers includes at least one communication device is configured to receive the from the first transducer through the electrical conductive hydraulic line via a sonic sensor of the second transducer,
wherein in response to the second transducer receiving the signal via the electrically conductive hydraulic line, the second transducer is configured to transmit the signal through the electrical conductive line via a respective sonic transmitter to another transducer of the set of transducers,
wherein a respective communication device of the another transducer receives the signal via its respective sonic sensor from the second transducer,
wherein each of the communication device and the respective communication device comprises a transceiver configured to perform on the signal at least one of filtering, error detection and correction, and deletion of information which can cannot be corrected; and
at least one vehicle component in communication with at least one of the communication device and the respective communication device; and
wherein the at least one vehicle component is electrically coupled to the common ground.

2. The system of claim 1 , wherein the at least one signal communication device is further configured to send a communication signal over the hydraulic line.

3. The system of claim 2 , wherein the at least one signal communication device is further configured to encode the communication signal.

4. The system of claim 2 , wherein the at least one signal communication device is further configured to decode the communication signal.

5. The system of claim 1 , wherein the at least one communication medium comprises an electrical conductor.

6. The system of claim 5 , wherein the signal comprises an electric power signal.

7. The system of claim 5 , wherein the common ground is a portion of a body of the vehicle.

8. The system of claim 1 , wherein one transducer of the set of transducers is configured to inject a current into an associated coil to impose a current through a conduction path including the electrically conductive hydraulic line and the common ground.

9. The system of claim 1 , wherein the at least one vehicle component comprises at least one of a controller, an associated sensor, an electronically powered device, and a communication network.

10. A method of communicating a communication signal in a vehicle, comprising:
receiving, by a specified transceiver from a set of transceivers of the vehicle, a first communication signal from an antenna including an electrically conductive hydraulic line electrically coupled to a common ground, the specified transceiver comprising a specified sensor;
communicating a second communication signal to a signal communication device via the hydraulic line, the second communication signal originating from the specified sensor and being received at another sensor associated with another transceiver from the set of transceivers;
wherein the communicating includes injecting by a transducer coil imposing a current loop through a conduction path including the electrically conductive hydraulic line and the common ground;
providing the second communication signal to one or more components of the vehicle by the signal communication device;
performing, by the another transceiver of the set of transceivers, on the second communication signal, at least one of filtering, error detection and correction, and deleting information which cannot be corrected, prior to providing the second communication signal; and
wherein at least one of the one or more components is electrically coupled to the common ground.

11. The method of claim 10 , further comprising decoding the second communication signal by the signal communication device.

12. The method of claim 10 , wherein prior to receiving the first communication signal, the method comprises:
sending the first communication signal by a second signal communication device.

13. The method of claim 12 , wherein prior to sending the first communication signal by the second signal communication device, the method comprises: encoding the first communication signal by the second signal communication device.

14. The method of claim 10 , wherein the signal communication device comprises a transceiver and a transducer.

15. The method of claim 10 , wherein providing the communication signal to one or more components of the vehicle by the signal communication device comprises providing the signal to a controller, a sensor, or a communication network.
