Appeal No. 95-1866
Application 07/878,500
The claimed invention is a location detecting system
for use in a moving body, which in the preferred embodiment is a
wheeled vehicle. Referring to Figure 1, a location detecting
unit 3 responsive to a gyro 1 and wheel sensors 2 calculates the
current position of the vehicle. A navigation controller 4
causes a memory drive 6 to retrieve the road map data for the
surrounding area from a road map memory 5, which may be a CD-ROM.
Display device 7 displays the surrounding road map information
together with a mark representing the current location of the
vehicle. The operator, using selection means such as a switch 13
located on the vehicle console 8, causes the system to operate in
either of two modes, a traveling mode and a simulation mode. In
the traveling mode, the sensor data are processed by location
detecting unit 3 for generating a real time display representing
the surrounding road map information including the current
location of the vehicle. In addition, the sensor data are stored
in a detachable memory unit 12 for later use in the simulation
mode. In the simulation mode, the location detection unit 3
receives the sensor data from the memory unit rather than from
the sensors. During simulation using stored sensor data, "a
