Motor Vehicle Navigation System
First Claim
1. A navigation system for use in a motor vehicle, comprising:
- a position sensor that that senses the geographic position of said navigation system and provides a first navigation system position signal indicative thereof;
a data bus;
a navigation computing unit that receives said first navigation system position signal, and transmits onto said data bus (i) a first position signal indicative of the position of a trip starting location, (ii) a second position signal indicative of a trip destination location, and (iii) said first navigation system position signal;
a monitor unit that includes a memory device that includes map data;
a monitor computing unit that receives from said data bus (i) said first position signal, (ii) said second position signal and (iii) said received navigation system position signal, and accesses said memory device to generate initial image data including map data indicative of the trip starting location, the trip destination and the current position of the navigation system; and
a display device responsive to said image data, to display an initial image indicative of said image data;
wherein said navigation computing unit receives a second navigation position signal indicative of a new position of said navigation system and transmits said second navigation position signal over said data bus to said monitor computing unit, which generates revised image data including map data indicative of the trip starting location, the trip destination and the updated position of the navigation system, which is provided for display on said display device.

Abstract
A motor vehicle navigation system comprises a position sensor that senses the geographical position of the navigation system and provides a first navigation system position signal indicative thereof. The navigation system system also includes a navigation computing unit that recieves the first navigation system position signal and transmits onto a data bus (i) a first position signal indicative of the position of a trip starting location, (ii) a second position signal indicative of a trip destination location and (iii) the first navigation system position signal. A road map memory device includes map data. A second computing unit recieves (i) the first position signal, (ii) the second position signal and (iii) the first navigaion system position signal and the map data, and generates initial image data including map data indicative of the trip starting location, the trip destination location and the current position of the navigation system, and a display displays an initial image indicative of the initial image data.

13. A method of generating an image for display by a motor vehicle navigation system that includes a navigation computing unit, a data bus and a monitor unit, comprising:
-
sensing the geographical position of the navigation system and providing a first navigation system position signal indicative thereof;
transmitting onto said data bus from the navigation computing unit (i) a first position signal indicative of the position of a trip starting location, (ii) a second position signal indicative of a trip destination location, and (iii) said first navigation system position signal;
receiving at the monitor unit said first position signal, said second position, and said first navigation system position signal;
generating, at the monitor unit, initial image data including map data indicative of the trip starting location, the trip destination location and the current position of the navigation system; and
displaying an initial image indicative of said initial image data.
