METHOD FOR MODIFYING NAVIGATION INFORMATION AND NAVIGATION APPARATUS USING THE SAME
First Claim
1. A method for modifying navigation information, comprising the steps of:
- (a) providing a navigation route to a carrier;
(b) basing upon the navigation route to generate an identification information;
(c) detecting an attitude angle of the carrier while the carrier is on the move;
(d) comparing the detected attitude angle with the identification information for determining whether the attitude angle is conformed to the identification information;
(e) directing the flow to proceed back to the step (c) for monitoring the attitude angle in a continuing manner, when the attitude angle is conformed to the identification information;
(f) modifying the navigation route when the attitude angle is not conformed to the identification information, and then directing the flow to proceed back to the step (c) for monitoring the attitude angle in a continuing manner.

Abstract
A method for modifying navigation information for guiding the driver is provided in the present invention, in which attitude angle of a carrier at a specific location is detected and compared with an identifying information for judging whether the carrier is on a correct route or not. In another embodiment, the present invention further provides a navigation apparatus according the foregoing method, which comprises an inertia navigation unit, a satellite signal receiving unit, a database, and signal processing unit. The signal processing unit generates a navigation route in accordance with the start and destination and determines whether the attitude angle is conformed to the identifying information with respect to the specific location on the navigation route. If the attitude angle is not conformed to the identifying information, the signal processing unit remodifies the navigation route for the carrier.

6. A navigation apparatus, being adapted for mounting on a carrier, comprising:
-
an inertia navigation unit, capable of sensing an attitude angle of the carrier; a satellite signal receiving unit, for receiving a satellite signal; a database, for storing a communication information of a road map and identification information corresponding to every specific location on the road map; and a signal processing unit, connected to the inertia navigation unit, the satellite signal receiving unit and the database, capable of generating a navigation route and comparing the identification information of a specific location on the navigation route with the attitude angle for determines whether the attitude angle is conformed to the identification information so as to generate a new navigation route when the identification information in not conformed to the attitude angle. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)
