Abstract: A system and method for making use of a removable device, such as a PDA, cellphone or similar device, in conjunction with a driver information system. The removable device is brought to a vehicle and data in the removable device is transferred to the vehicle. This data can be data that is normally stored in the removable device, such as contact data, or it can be data that the operator has selected and loaded into the removable device for transport to the vehicle, for instance to update the vehicle information system. Data can also be transferred from the vehicle to external systems by transporting it in the removable device.

Abstract: A vehicle information system which includes an in-vehicle system 105 and a centralized server system 120. The in-vehicle system communicates with the server system using a wireless communication link 110, such as over a cellular telephone system. A position system, such as a set of GPS satellites 140, provides positioning signals that are used by the in-vehicle systems, and optionally by the centralized server system to increase the accuracy of position estimates. In one version of the system, an operator specifies a destination to an in-vehicle system which validates the destination. The in-vehicle system transmits specification of the destination to a server system 125 at the centralized server. The server system computes a route to the destination and transmits the computed route to the in-vehicle system. The in-vehicle system guides the operator along the route.

Abstract: A combination of manual and voice input for a telematics system reduces visual distraction, works reliably, and is low cost. The telematics system uses a menu-based interface to communicate with the driver. This menu-based interface is accessible to the driver using both manual interactions and by voice. A reliable manual input mechanism is available using turn or push buttons in addition to voice recognition, which may not be accurate in all operating conditions. Voice recognition inputs can be limited to small numbers of words or phrases that can be more easily distinguished by a voice recognizer. Furthermore, voice outputs of the system are tailored to that they are readily recognizable to the driver. Manual input is optionally rejected in operating conditions in which such input is dangerous or prohibited.

Abstract: A vehicle navigation system 10 utilizing a wireless communications medium 74 for transmitting present position 77 and destination position 75 data to a central processing means 14 for generating a route. The central processing means generates a series of turn-by-turn routing vectors 82-87 comprising the route. The wireless communications medium transmits the turn-by-turn routing vectors to the vehicle for display either audibly or visually or both to the vehicle operator 34. A vehicle identification means can be used for updating the routing vectors upon subsequent transmissions.

Abstract: A transceiver for transmitting and receiving coded light through a motor vehicle windshield from an in-vehicle computer. The coded light is binary encoded data that is first transmitted through the windshield by light emitting diodes in the red, green, or yellow light range or a similar light range that is not attenuated by the windshield. A photo diode receives the transmitted encoded light and operates a transistor switch amplifier means to activate one or more infrared light emitting diodes connected in parallel. A power supply comprising a light source on the inside of the vehicle and a solar cell on the outside of the windshield provides the necessary power to activate the circuitry on the outside of the windshield. The complete unit is mounted on the windshield in an area which is out of the driver's normal vision.
