The on-vehicle information terminal according to the present invention comprises an abridged road generating device that generates abridged roads by abridging a road map based upon map data, a road decision-making device that makes a decision as to whether or not a road is a special shape road having a predetermined special shape based upon the map data, a substituting device for substitutes a specific road shape pattern stored in memory in advance for a road determined by the road decision-making device to have a special shape and a display control device that displays at the display device an abridged map containing specific road shape patterns used to substitute for special shape roads by the substituting device and the abridged roads generated by the abridged road generating device.

On-vehicle information terminal, abridged map generating apparatus, abridged map display method and display apparatus

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.

On-vehicle information terminal

An on-vehicle information terminal comprises a route search unit that searches for a plurality of routes connecting a current position to a destination and a characteristics extraction unit that extracts characteristics of each route searched by the route search unit based upon geographic names. The on-vehicle information terminal displays the characteristics of individual routes extracted by the characteristics extraction unit at a display device.

On-vehicle information terminal route characteristics extraction apparatus and route characteristics display method

An on-vehicle information terminal generates an abridged map by abridging a map based upon map data and displays the abridged map. The on-vehicle information terminal comprises an abridgment factor setting unit that sets an abridgment factor indicating an extent to which the map is to be abridged, a map abridging unit that generates the abridged map with specific contents in correspondence to the abridgment factor set by the abridgment factor setting unit and a display unit that displays the abridged map generated by the map abridging unit.

On-vehicle information terminal abridged map generation apparatus and abridged map generation method

A navigation apparatus includes a route searching unit that searches for a plurality of routes from a departure point to a destination and a map display control unit that displays a map of the plurality of routes searched out by the route searching unit upon a display monitor, and, if any two or more among the plurality of routes overlap upon and pass along a same road, the map display control unit displays the overlapping portions as shifted.

Navigation apparatus, map data distribution apparatus, map data distribution system and map display method

A navigation apparatus includes: a route search unit that obtains a route to take from a start point to a destination; a vehicle position detection unit that detects a vehicle position; and a route guidance unit that provides route guidance based upon the obtained route. And the route guidance unit displays the route within a predetermined range from the vehicle position as a straight bar together with the vehicle position, displays an intersection indicator on the straight bar in correspondence to an intersection present within the predetermined range on the route and varies display mode when displaying the intersection indicator depending upon whether the intersection is a guidance-requiring intersection at which the route guidance is provided or a non-guidance intersection at which the route guidance is not provided.
