On-vehicle information terminal
First Claim
1. An on-vehicle information terminal, comprising:
- a current position detection unit that detects a current position of a subject vehicle;
a route setting unit that sets a route from the current position of the subject vehicle detected by the current position detection unit to a destination; and
a display control unit that displays at a display device an enlarged map around a next guidance-requiring intersection on the route having been set by the route setting unit, wherein;
the display control unit displays the enlarged map by displaying the current position and the next guidance-requiring intersection in a single screen at the display device and rendering the route extending between the current position and the next guidance-requiring intersection as a straight line, even in a case that the route extending between the current position and the next guidance-requiring intersection is curved.

Abstract
An on-vehicle information terminal includes a current position detection unit that detects the current position of the subject vehicle, a route setting unit that sets a route from the current position of the subject vehicle detected by the current position detection unit to a destination and a display control unit that displays at a display device an enlarged map around the next guidance-requiring intersection on the route having been set by the route setting unit. The display control unit displays the enlarged map by displaying the current position and the next guidance-requiring intersection in a single screen at the display device and rendering the route between the two points as a straight line.

11. An on-vehicle information terminal, comprising:
-
a current position detection unit that detects a current position of a subject vehicle; a route setting unit that sets a route from the current position of the subject vehicle detected by the current position detection unit to a destination; and a display control unit that displays at a display device an enlarged map;
around the next guidance-requiring intersection on the route having been set by the route setting unit, wherein;a plurality of display modes are available for displaying the enlarged map; and the display control unit displays the enlarged map by switching to one of the plurality of display modes; three different display modes, including a mode for displaying a simple enlarged map by displaying a map at a predetermined scaling factor over a specific range around the next guidance-requiring intersection, a mode for displaying a linear enlarged map in which the route between the current position and the next guidance-requiring intersection is rendered as a straight line, and a mode for displaying an alternative enlarged map by displaying an abridged map generated by abridging a map over a range containing the current position and the next guidance-requiring intersection, are available for displaying the enlarged map; and the display control unit displays one of the simple enlarged map, the linear enlarged map or the alternative enlarged map. - View Dependent Claims (12, 13, 14, 15)
