Abstract

A sensing system for providing vehicle automation. The system includes a master controller that is electrically connected to a receiver that has a transceiver that provides over-the-air communication to a plurality of wireless sonic sensors. The transceivers receive information from the plurality of wireless sonic sensors in order to automate the control of the vehicle to ensure the vehicle drives in a straight line.

Claims

1. A sensing system for an automated vehicle comprising:

a master controller;

at least one receiver having a first transceiver in electric communication with the master controller; and

a plurality of wireless sonic sensors in over-the-air communication with the first transceiver of the receiver to communicate information to the first transceiver.

2. The sensing system of claim 1 wherein the first transceiver is a wireless radio link.

3. The sensing system of claim 1 wherein the at least one receiver has a second transceiver that scans radio channels.

4. The sensing system of claim 3 wherein each of the plurality of sensors has a transceiver that communicates the information over a radio channel to the first transceiver of the receiver.

5. The sensing system of claim 4 wherein based on the radio channels scanned the receiver communicates with the plurality of sensors to change the radio channel of the plurality of sensors.

6. The sensing system of claim 1 wherein at least one of the plurality of wireless sensors has an RFID reader.

7. The sensing system of claim 1 wherein the receiver transmits a time triggered beacon to the plurality of sensors.

8. The sensing system of claim 7 wherein the plurality of wireless sonic sensors communicate the information in response to receiving the time triggered beacon.

9. The sensing system of claim 8 wherein the receiver communicates the information communicated to the first transceiver to the master controller.

10. The sensing system of claim 9 wherein the master controller steers the vehicle in response to the information communicated to the master controller.

11. The sensing system of claim 10 wherein the vehicle is a road paving machine.
