Navigation Apparatus Providing Directions

The present invention relates to a navigation device. Specifically, the present invention relates to a navigation device that provides a direction indication.

More particularly, the present invention relates to a navigation device for providing a direction indication according to a wired or wirelessly received driving direction indication signal.

In general, a navigation system displays a current position of a moving object calculated using information received from a positioning device (GPS) on a map displayed on a display screen. In addition, the navigation system displays various information necessary for driving such as displaying the moving direction of the moving object, the distance to the destination to be traveled, the current moving speed of the moving object, the path set before the driver, the optimum path to the destination, and the like. To provide.

The most essential part of the principle of navigation begins with an understanding of GPS. Your car is moving through GPS to pinpoint your current location and distance to your destination. Unlike many devices that use GPS receivers (such as unattended camera search and traffic location indications), navigation uses GPS receivers to locate locations on a map. GPS navigation is sometimes difficult to receive satellite signals in deep mountains, tunnels, underground roads, etc. Because of the sensors attached to the vehicle to correct the position of the vehicle.

Such a navigation system (or GPS positioning device) is currently mounted on various kinds of moving objects such as ships, aircrafts, automobiles, etc., and is widely used to check the current position and moving speed of moving objects or determine a moving path.

In general, the navigation of the vehicle is displayed on the map on which the direction indication of the driving direction is displayed along with the voice guidance. Since the display screen is small and the map is small, it is difficult for the driver to easily recognize the direction indication. Due to the noise and driving concentration, it was difficult to be recognized easily, and due to the nature of hearing, the accuracy of information was lower than that of vision.

In order to solve this problem, a conventional navigation system (Patent No. 10-0335946) limits a system including a projection apparatus for projecting a voice guidance device and a direction-related display onto the windshield glass.

The present invention is to solve the above problems, first, by displaying the driving direction guidance guided in the navigation through the direction indicator installed on the windshield of the vehicle, the driver recognizes the direction indication information more clearly displayed by the navigation At the same time, to provide a navigation device that can be more easily recognized.

In addition, the present invention is to provide a navigation device that allows the driver to be more easily recognized by transmitting the driving direction display wirelessly and by performing a power supply using a solar cell to reduce the visual disturbance due to the wire.

In addition, the present invention is to provide a navigation device that can be recognized more easily with less front view disturbance of the driver through wireless power transmission.

The present invention is to solve the above problems, the navigation device for providing a direction indication according to the present invention, a navigation device for receiving a GPS signal and providing a route guidance, the voice guidance for the vehicle driving direction according to the set route A control unit which controls to provide and controls to transmit a driving direction indication signal; A direction display signal transmission unit for transmitting a driving direction display signal to a direction display unit according to a control signal of the controller; And a direction indicator unit attached to the front glass of the driver vehicle to receive the driving direction indication signal from the direction indication signal transmission unit and wired or wirelessly, and including a direction indicator to display the driving direction according to the received signal. It is characterized by including.

The driver recognizes the direction indication information displayed by the navigation more clearly by displaying the driving direction indication guided in the navigation through the navigation device providing the direction indication according to the present invention through the direction indicator installed on the windshield of the vehicle. At the same time, it became easier to recognize.

In addition, according to another embodiment of the present invention, by wirelessly transmitting the driving direction display and by the power supply using the solar cell to reduce the disturbance of the view due to the wired, the driver can easily recognize the direction display. It became possible.

In addition, according to another embodiment of the present invention, wireless power transmission makes it easier to recognize the driver's frontal view while having less frontal disturbance.
