The present invention relates to a navigation system, and more particularly to a navigation system for guiding a driver to a destination.

Navigation is a device or program that helps you navigate through guidance.

Generally, it is installed in a car and is used to transmit information such as a location and a surrounding map to a user, and to indicate a route or a shortest distance to a destination.

It combines GPS technology and mobile communication technology to provide optimal route from the driver to the destination by collecting, analyzing and providing traffic information of various alternative routes in real time to reduce traffic congestion and provide safe and convenient driving environment .

The conventional navigation system receives only information about its current position from the satellite and guides the route to the destination. However, the current navigation system provides the front traffic situation information in real time using the wireless communication technology.

That is, if the conventional technique emphasizes the shortest distance to the destination, it is changed to an optimal path for real time.

The navigation system technology is a state-of-the-art technology that is applied to various industrial fields such as electric, electronic, communication, and automobile.

In addition, in the conventional navigation system, when the driver drives a new area or a start route, or a novice driver drives the vehicle, the destination is inputted to the navigation and the vehicle travels in a direction to guide the navigation.

At this time, the driver meets a crossing point such as an intersection, a range or a crossing road of another area or a start road, and the momentary driver worries about which direction to turn at the crossing point.

Here, the information necessary for the driver needs information such as a left turn, a right turn, a straight turn, a U-turn or a P-turn in order to move to an optimal route to a destination.

In the conventional navigation system, the driver rotates more than the direction information necessary for reaching the destination and provides the driver with preferential information about the feature name such as the road name and the name of the building into which the vehicle enters, and then, Direction information is provided later.

Therefore, when the driver drives the other region or the start road, It is difficult to change the lane in advance in advance, and there is a problem in that a traffic accident can be caused by attempting to change the lane forcibly.

In addition, the time difference between the information about the provided feature item and the direction information provided later may be as short as 4 seconds to 5 seconds, or as long as 10 seconds.

Here, if the vehicle travels at a speed of 60 kilometers per hour, it travels 16.6 meters per second. If traveling at 40 kilometers per hour, it travels 11.1 meters per second.

Also, when driving a vehicle in a downtown area, the traffic volume is large, so it is often necessary to change the lane from a previous distance sufficient to reach an intersection.

The conventional navigation system provides the information about the feature to be provided first and the information of the direction to be rotated at a later time so that the driver can know the information about the feature when driving the start area or the beginner's road, There is a problem that a traffic accident may be caused by unintentionally passing over a direction change point or attempting to change the lane forcibly.

Therefore, when the moving vehicle enters the direction change point, the direction information necessary for the driver is provided before the feature information, and the driving information to be traveled by the vehicle is provided before the sufficient time from the direction change point, There is a need for a navigation system that guides the switching direction of the vehicle so that the driver can change the lane with time and operate safely and comfortably.

It is an object of the present invention to provide a navigation system for guiding direction information necessary for a driver ahead of feature information when a driver enters a direction switching point.

It is another object of the present invention to provide a navigation system for guiding vehicles ahead of a predetermined distance before entering a direction switching point through guidance means such as voice, alarm, character, or screen flicker do.

It is another object of the present invention to provide a navigation system that guides the number of intersections that must travel from a present position of a vehicle to a point where a direction change should be executed.

The navigation system that guides the direction of change of the vehicle according to the present invention provides direction information necessary for the driver when the driver enters the direction change point of the other area or the start road ahead of the feature information so that the driver is more secure It is possible to prevent the occurrence of a traffic accident by executing the direction switching effortlessly.
