摘要:
Disclosed is a single or multi-route map matching apparatus in a system which provides a navigation service via a mobile communication terminal. The map matching apparatus comprises: an information center for calculating an optimum route to a destination inputted by a user based upon a present location of the mobile communication terminal, and generating a format of route data based upon the calculated optimum route; and an Intelligent Transportation System (ITS) terminal for detecting the present location of the mobile terminal to generate location data, processing the route data, performing map matching based upon the location data to determine whether the user travels on a given route or departs from the route, and performing road guidance based upon a result of the map matching.

摘要:
A method for transmitting and for storing destination information in a mobile communication terminal is disclosed. The method for transmitting destination information includes determining whether a navigation mode is enabled and, if the navigation mode is enabled, determining whether a hot key is pressed for a predetermined time. If the hot key is pressed for the predetermined time, destination address information corresponding to the hot key is read, and transmitted to an information center over a wireless network. Therefore, since a phone book of the mobile communication terminal is interworked with destination address information for navigation, the present invention simplifies procedures needed to transmit the destination address information using the mobile communication terminal.
摘要:
An automatic frequency tuning apparatus including an FM radio receiver for receiving a frequency tuning identification sound signal corresponding to a reception frequency of the FM radio receiver and then outputting the received frequency tuning identification sound signal; and a terminal's FM transmitter for outputting a frequency tuning identification sound while changing a transmission frequency, and automatically tuning the transmission frequency to the reception frequency of the FM radio receiver depending on whether a frequency tuning identification sound output from the FM radio receiver is input through a microphone. The automatic frequency tuning apparatus can automatically tune frequencies between the terminal's FM transmitter and the FM radio receiver, even without manual input by the user.

Disclosed is a method for finding a path in a navigation system. The method includes selecting a sectional path option for a specific section selected by a user from an entire section between a start point and an end point, and finding a path in the specific section according to the sectional path option and creating an entire path for an entire section by employing the path in the specific section. Accordingly, a sectional path option different from an entire path operation for an entire path is applied to a specific section desired by a user on an entire path to an end point from a start point, so that it is possible to efficiently apply an option desired by the user to path finding.
摘要:
Disclosed are an apparatus and a method for computing a position of a moving entity, and an apparatus and method for setting a gyroscope zero point or a gyroscope zero point reference value. In the apparatus for setting the gyroscope zero point, a gyroscope outputs a signal of angular velocity in the form of voltage. A global positioning system (GPS) receiver receives a GPS signal. An analog-to-digital (A/D) converter digitizes the voltage output from the gyroscope. A controller detects a speed and a direction angle of a vehicle from the received GPS signal, determines if the vehicle is traveling in a straight line, and filters the voltage output from the gyroscope to obtain a gyroscope zero point reference value if the vehicle is traveling in the straight line.
