Abstract
An autonomous vehicle capable of determining its position in a space through improved communications with beacons is disclosed. The autonomous vehicle utilizes time of flight as well and angular information to determine position, and is capable of intelligent interaction with the beacons.
Claims19
An autonomous vehicle comprising:
- a mobile unit;
- a sonic transmitter situated on the mobile unit and configured to transmit a sonic signal to a beacon located at a position that is remote from the mobile unit;
- an electromagnetic receiver situated on the mobile unit configured to receive an electromagnetic signal generated by the beacon in response to the sonic signal from the transmitter and to determine an angle of reception of the received electromagnetic signal and time of flight information of the sonic signal over a path from the mobile unit to the beacon;
- and
- a processor configured to utilize the determined angle of reception and time of flight information to determine a current position of the mobile unit relative to the beacon;
- wherein said processor assigns a dynamic weight to each of the determined angle of reception and time of flight information.
