Method and apparatus for variable speed route simulation operation for navigation system
First Claim
1. A method of conducting a route simulation operation on a screen of a navigation system, comprising the following steps of:
- calculating a route from a starting point to a destination specified by a user;
determining a first route simulation speed for a first part of the calculated route having a preset number of first turns from the starting point, the first route simulation speed being slow enough for the user to familiarize with the preset number of first turns;
determining a second route simulation speed for a second part of the calculated route having a preset number of last turns before the destination, the second route simulation speed being slow enough for the user to familiarize with the preset number of last turns;
determining a third route simulation speed for a part that extends between said first part and said second part of the calculated route, the third route simulation speed being higher than the first or second route simulation speed; and
displaying a progression indicator on the calculated route to the destination on a map image on the screen of the navigation system and moving the progression indicator based on the simulation speeds determined in the above steps.

Abstract
A method for route simulation operation on a navigation system is able to complete the route simulation operation within a short period of time. The method includes the steps of: calculating a route from a starting point to a destination; determining a first route simulation speed for a preset number of first turns from the starting point; determining a second route simulation speed for a preset number of last turns before the destination; determining a third route simulation speed for a remaining part of the calculated route; and displaying a progression indicator on the calculated route to the destination on a map image on the screen of the navigation system and moving the progression indicator based on the simulation speeds determined in the above steps.

11. An apparatus for conducting a route simulation operation on a screen of a navigation system, comprising:
-
an input device for a user to specify a destination in the navigation system to calculate a route from a starting point to the destination; a route simulation controller for determining a first route simulation speed for a first part of the calculated route having a preset number of first turns from the starting point, the first route simulation speed being slow enough for the user to familiarize with the preset number of first turns; the route simulation controller determines a second route simulation speed for a second part of the calculated route having a preset number of last turns before the destination, the second route simulation speed being slow enough for the user to familiarize with the preset number of last turns; the route simulation controller determines a third route simulation speed for a part that extends between said first part and said second part of the calculated route, the third route simulation speed being higher than the first or second route simulation speed; and a display controller for controlling an operation of the screen based on the instruction from the route simulation controller for displaying a progression indicator on the calculated route to the destination on a map image on the screen of the navigation system and moving the progression indicator based on the simulation speeds determined by the route simulation controller. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
