Abstract:
1. A car navigation system comprising: a map generator configured to display at least one of two-dimensional maps, three-dimensional maps and bird's-eye-view maps, from mapping information provided from a database; a position detector adapted to detect a position of a vehicle; a search unit adapted to search for a route between the detected vehicle position and a specified target position, or a specified departure position and the specified target position, under set conditions; a map summarizing unit adapted to generate a summary road map having a reduced amount of information and having deformed roads more orthogonalized and/or linearized than the at least one of two-dimensional maps, three-dimensional maps and bird's-eye-view maps, and including a simplified route between the detected vehicle position and the specified target position, or the specified departure position and the specified target position, with highlighted lines, by applying a summarizing operation including at least one of an orthogonalizing and linearizing operation over a main road including a running route; a display unit adapted to display the summary road map of the simplified route; and a communication unit for receiving traffic information, and wherein the display unit displays the traffic information received by the communication unit on the summary road map with respect to a corresponding route displayed thereon.
