First Claim
Patent Images
1. An on-board vehicular system for use with a remote navigation server including a navigation data base, a route calculator and a voice message recognition and generation system, the on-board vehicular system comprising:
- a global positioning system (GPS) receiver adapted to generate vehicular location coordinates in response to signals received from a GPS;
a transceiver module for recognizing operator commands, for generating commands to the operator and for sending, receiving and storing data messages, the transceiver module coupled to the GPS receiver for receipt of vehicle coordinate data;
a mobile phone coupled via a wireless communication medium to the transceiver module and adapted to send vehicle coordinate data and route requests from the transceiver module to the remote navigation server and further adapted to receive navigational route information generated by the route calculator and to forward received information to the transceiver module via the wireless communication medium; and
an instruction unit associated with the transceiver module for communicating to the operator turn-by-turn directional navigation instructions generated by the transceiver module in response to received navigational route information.

Abstract
A vehicle navigation system communicates with a remote navigation server to download turn-by-turn command information via a mobile phone communication channel. After the mobile phone is disconnected from the remote server, an on-board transceiver module generates turn-by-turn command information to the vehicle operator in voice and/or visual form.

11. A method for assisting an operator in navigating a vehicle, the method comprising the steps of:
-
activating a global positioning system receiver on board the vehicle to generate vehicle location coordinates;
activating a transceiver module on board the vehicle and presenting an operator request for service thereto;
wirelessly activating a mobile phone via the transceiver module and a wireless communications medium to establish a mobile phone communication channel between the transceiver module and a remote navigation server in response to the voice request;
sending a vehicle destination identification via an operator routing message to the remote navigation server via the transceiver module, the wireless communication medium and the mobile phone communication channel;
sending the vehicle location coordinates to the remote navigation server via the transceiver module, the wireless communication medium and the mobile phone communication channel;
calculating, at the remote navigation server, turn-by-turn navigational command information and downloading the calculated information to the transceiver module via the mobile phone communication channel and the wireless communication medium; and
generating turn-by-turn navigational instructions to the operator at the transceiver unit using the downloaded navigational command information. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
deactivating, after the step of calculating and downloading, the mobile phone communication channel in response to a signal from the transceiver unit.
-
-
13. The method of claim 12 comprising the further step of:
initiating at the remote navigation server a subsequent communication channel to the mobile phone after the step of deactivating.
-
14. The method of claim 13 wherein the step of initiating occurs at any time during the step of generating.
-
15. The method of claim 14 comprising the further steps of:
-
downloading updated turn-by-turn navigational command information from the remote navigation server to the transceiver unit; and
generating updated turn-by-turn navigational instructions to the operator at the transceiver unit using the downloaded updated navigational command information.
-
-
16. The method of claim 11 comprising the further step of:
visually displaying the turn-by-turn navigational instructions to the operator.
-
17. The method of claim 16 wherein the displaying occurs at a rear view mirror of the vehicle.
-
18. The method of claim 11 comprising the further step of:
audibly informing the operator of the turn-by-turn navigational instructions via a speaker associated with the transceiver unit.
-
19. The method of claim 11 wherein the step of activating the transceiver module includes presenting an operator voice request for service thereto.
-
20. The method of claim 16 wherein the displaying occurs at a radio of the vehicle.
-
21. The method of claim 17 wherein the speaker is associated with a radio of the vehicle.
-
22. The method of claim 11 wherein the step of sending a vehicle destination identification is effected via an operator voice command.
