Abstract
Abstract In a driving simulation apparatus for executing route retrieval on the basis of digital map data obtained by digitizing a road network, displaying the route so retrieved on a display unit and scrolling the map while tracing the route so displayed for simulation driving, the scrolling speed is changed in accordance with a reduced scale of the map displayed. When a wide area map is displayed, for example, an updating distance becomes long and when a detailed map is displayed, the updating distance becomes short. Therefore, even when the wide area map is displayed, the scrolling speed on the screen of the display unit does not become slow, and a long time is not necessary even when long distance retrieval is made.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
69 words
A driving simulation apparatus comprising: means for retrieving a route based on digital map data obtained by digitizing a road network; means for displaying the route so retrieved on a display unit; means for scrolling the map while tracing the route displayed on said display unit for simulation driving; and means for automatically setting an updating distance in accordance with a reduced scale of a map to be displayed.
Claim 2
Dependent Claim
69 words
A driving simulation apparatus comprising: means for retrieving a route based on digital map data obtained by digitizing a road network; means for displaying the route so retrieved on a display unit; means for scrolling the map while tracing the route displayed on said display unit for simulation driving; and means for automatically setting an updating distance in accordance with a reduced scale of a map to be displayed.
Claim 3
Dependent Claim
42 words
A driving simulation apparatus according to claim 1, wherein said means for automatically setting an updating distance increases an updating distance when the reduced scale of a display map is great and decreases the updating distance when the reduced scale is small.
Claim 4
Dependent Claim
23 words
A driving simulation apparatus according to claim 1, which further comprises means for displaying a route guide for an arbitrary time during simulation.
Claim 5
Dependent Claim
26 words
A driving simulation apparatus according to claim 1, which further comprises means for stopping scrolling of the map during simulation in accordance with an input signal.
Claim 6
Dependent Claim
24 words
A driving simulation apparatus according to claim 1, which further comprises a map having a hierachical structure having different reduced scales as said map.
Claim 7
Dependent Claim
60 words
A driving simulation method comprising: executing route retrieval based on map data obtained by digitizing a road network; displaying the route so retrieved on a display unit; scrolling the map while tracing the route displayed on said display unit for simulation driving; and automatically setting an updating distance in accordance with a reduced scale of a map to be displayed.
Claim 8
Dependent Claim
60 words
A driving simulation method comprising: executing route retrieval based on map data obtained by digitizing a road network; displaying the route so retrieved on a display unit; scrolling the map while tracing the route displayed on said display unit for simulation driving; and automatically setting an updating distance in accordance with a reduced scale of a map to be displayed.
