Abstract

Route guidance systems provide a driver with real-time, turn by turn advice to reach a selected destination. The driver uses the Driver Interface shown in Figure 1 to enter the destination in the form of an address or intersection by selecting street names from a list or typing them in on a keyboard. The Navigation Computer then calculates the route and presents a series of maneuvers as the route is traversed. The data entry can be tedious, and is prone to error if the person entering the information is unsure of or unfamiliar with the name or the spell- ing ofa street name or city.

The Navigation Computer then calculates the route and presents a series of maneuvers as the route is traversed. The data entry can be tedious, and is prone to error if the person entering the information is unsure of or unfamiliar with the name or the spell- ing ofa street name or city.

  If a route guidance system is installed in a chauffeur-driven vehicle such as a taxi or limou- sine, the passenger will have to provide the driver with a destination, spelling out complicated or unknown street names or suburbs to ensure proper and accurate data entry. A Passenger Interface installed in the passenger compartment provides a means for the passenger to enter the destination directly, without the need for the driver to enter any data.

  In addition to eliminating errors, the destina- tion can be entered while the vehicle is already in motion without distracting the driver or compro-

mising safety.

  The Passenger Interface, mounted in the rear seat area, is activated when the driver requires that a destination be entered. The device may or may not ha...
