In particular, the information providing service using the navigation built into the vehicle or built-in vehicle can provide the necessary information required to the driver when driving the vehicle, the demand is rapidly increasing.

Navigation basically saves map information and works with the GPS (Global Positioning System, GPS) to get real-time driving information of the vehicle, such as driving direction and driving destinations. It is an information terminal that provides the distance, the current speed of the vehicle, the optimum route to the destination and the like with the map.

Recently, in addition to these basic functions, it also provides various entertainment functions such as a digital broadcast reception function, a multimedia playback function, and an audio playback function.

Typically, the best route to a destination provided by navigation is to provide the shortest route from the current vehicle location to the destination, or to meet the conditions required by the driver (e.g., toll roads, highway routes, etc.). Provide the path.

However, such a conventional navigation only provides information on a moving path of a vehicle that is being driven, but does not provide information on a moving path of another vehicle. In particular, emergency vehicles such as ambulances, police cars, and fire trucks are required to arrive at their destinations quickly, and these vehicles are frequently blocked by other vehicles on the move and arrive late at their destinations. Therefore, if the navigation route of such emergency vehicles can be known from the navigation system installed in the vehicle, the navigation route of the emergency vehicle can be avoided in advance so that the emergency vehicles can quickly reach their destination, but such navigation is still provided. It is not becoming.

The present invention has been made to solve the above-mentioned problems of the prior art, so that the navigation path of the emergency vehicle is displayed on the navigation terminal of the driving vehicle so that the emergency vehicle can quickly reach the destination by avoiding the movement path of the emergency vehicle. An object of the present invention is to provide a method for providing emergency vehicle location information of a car navigation system.

Hereinafter, with reference to the accompanying drawings an embodiment of the emergency vehicle position information providing method of the vehicle navigation according to the present invention will be described in detail.

1 is a block diagram showing the structure of a navigation vehicle navigation terminal according to the present invention, Figure 2 is a schematic diagram of a system in which a method for providing emergency vehicle position information of a vehicle navigation according to the present invention is executed, Figure 3 is FIG. 1 is a flowchart illustrating an embodiment of a method for providing emergency vehicle location information for vehicle navigation according to the present invention.

4 is a diagram illustrating a route changing method when the emergency vehicle is close to the driving vehicle in the method for providing emergency vehicle position information of the vehicle navigation according to the present invention, and FIG. 5 is the emergency vehicle position of the vehicle navigation according to the present invention. In the information providing method, it is shown in the navigation when an accident occurs on the moving route of the driving vehicle.

Emergency vehicle location information providing method of the vehicle navigation according to the present invention is executed in the car navigation, providing information on the location information of the emergency vehicle 50 to the driver of the driving vehicle 20 or information about the accident situation occurring on the road By providing a driver to bypass the emergency vehicle 50 or to bypass the congested road caused by a sudden situation.

The emergency vehicle location information providing method of the vehicle navigation is made in several steps.

First, a process of searching for movement route information from a current position of the driving vehicle 20 to a destination set by the driver is performed. When the driver manipulates the input unit 12 of the navigation terminal 10 mounted on the vehicle 20, the navigation terminal transmits various information such as the position and time transmitted from the plurality of GPS satellites 40 through the GPS receiver 13. Receives and extracts information such as the current location, speed, roads of the driving vehicle 20 from the received information. In other words, the movement route information of the driving vehicle 20 receives various information from the GPS satellite 40 through the GPS receiver 13 provided in the navigation terminal 10 of the driving vehicle 20, and the navigation terminal ( The controller 11 extracts a variety of databases such as a map database and a facility database stored in the memory 14 of FIG.

By operating the navigation terminal 10 as described above, various driving information is collected, and the navigation route information of the emergency vehicle 50 is the navigation terminal 10 of the driving vehicle during normal operation along the movement route designated by the navigation terminal 10. ) Is displayed.

To describe this process in more detail, when an emergency occurs in an area such that a police car, a fire engine, an 119 ambulance, or a tow truck emerges, the driver of the emergency vehicle 50 is mounted inside. Manipulate the navigation terminal to extract the fastest route information to the destination.

The extracted movement route information of the emergency vehicle 50 is transmitted to the central control center 30 by the driver who drives the emergency vehicle 50. The movement route information of the emergency vehicle 50 is the emergency vehicle 50. It is transmitted to the central control center 30 through the RF antenna of the navigation terminal installed in. The movement path information of the emergency vehicle 50 transmitted to the central control center 30 is transmitted to the GPS satellite 40 again, and the GPS satellite 40 transmits the movement path information to the navigation terminal of the driving vehicle 20. To transmit. Of course, the movement route information of the emergency vehicle 50 transmitted to the central control center 30 may be transmitted to the navigation terminal of the driving vehicle 20 directly from the central control center 30 without passing through the GPS satellite 40. The movement path of the emergency vehicle 50 directly transmitted from the central control center 30 or transmitted through the central control center 30 and the GPS satellite 40 is provided in a communication unit provided in the navigation terminal of the driving vehicle 20 ( 16).

The RF antenna transmits the tag information generated by the navigation terminal of the emergency vehicle to the outside. When an emergency occurs in the tag information and the driver of the emergency vehicle 50 needs to move quickly from the current position to the destination, Emergency situation information, movement route information, and the like. The tag including this information is transmitted to the central control center 30 through the RF antenna.

On the other hand, the movement route information reception of the emergency vehicle 50 is preferably executed only when the emergency vehicle 50 transmits its location information sharing request message to the central control center (30). That is, the driver of the emergency vehicle 50 transmits a message to the central control center 30 indicating that the driver may share the movement route information with the other driving vehicle 20 with respect to the movement route to the destination to which he / she currently needs to go. Only when the vehicle 20 is able to receive the movement route information of the emergency vehicle (50). This is because not all cases in which emergency vehicles such as police cars or ambulances also operate are urgent.

For example, an ambulance is not an emergency but a general situation, such as going to a particular gas station to refuel or to repair a breakdown. In this case, when the movement route of the emergency vehicle 50 is transmitted to the other driving vehicles 20, the drivers of the other driving vehicles 20 adopt a different detour route instead of the earliest traveling route originally searched. Because it is operating, because it can cause time and economic damage to the other driving vehicle (20). Therefore, only when the emergency vehicle 50 such as an ambulance is driven due to an emergency situation such as patient transportation, the driver of the emergency vehicle 50 transmits the movement route sharing request message of the emergency vehicle to the central control center 30.

When the communication unit 16 of the driving vehicle 20 navigation terminal 10 receives the movement route information of the emergency vehicle 50 through the above-described process, the navigation terminal of the driving vehicle 20 may move to the driving vehicle 20. The movement route information and the movement route information of the emergency vehicle 50 are displayed. The movement route information of the driving vehicle 20 and the movement route information of the emergency vehicle 50 are displayed in a map form with a brief description and the like by the display unit 15 of the navigation terminal 10.

As described above, when the movement path information of the driving vehicle 20 and the movement path information of the emergency vehicle 50 are displayed on the navigation terminal 10 of the driving vehicle 20, the navigation terminal of the driving vehicle 20 is an emergency. Compare the driving route of the vehicle 50 and the driving route of the driving vehicle 20, and if the moving route is the same, search for the detour route information so that the driving vehicle 20 may avoid the emergency vehicle 50. . In this way, by providing a route that the driving vehicle 20 can avoid the emergency vehicle 50, the driving vehicle 20 gives an effect of yielding the road to the emergency vehicle 50, and as a result, the emergency vehicle 50 has the advantage of being able to perform the task quickly. Of course, the navigation route and the detour route of the vehicle 20 first searched are displayed on the terminal of the navigation of the vehicle 20 to allow the driver of the vehicle 20 to select which route to go.

Here, if the movement route of the driving vehicle 20 and the emergency route 50 are not the same, but the driving vehicle 20 and the emergency vehicle 50 meet at a certain area when driving at the current movement speed. In other words, when the movement route of the driving vehicle 20 and the emergency vehicle 50 overlaps in a certain area, the operation of the detour route except for the previously discovered fast movement route causes time and economic damage. In this case, in order to avoid the emergency vehicle 50 and the driving vehicle 20 from overlapping on the moving path, the navigation terminal of the driving vehicle 20 provides a voice or text display to reduce the speed of the driving vehicle. .

On the other hand, the detour route information search as described above is preferably performed only when the emergency vehicle and the driving vehicle is located within the predetermined reference distance (R). Because the driving vehicle 20 and the emergency vehicle 50 have the same movement route, the driving vehicle 20 may be connected to the emergency vehicle 50 as if the emergency vehicle 50 is far ahead of the driving vehicle 20. This is because it is not necessary to display the movement route information of the emergency vehicle 50 in a situation where the driving flow is not disturbed in the navigation terminal 10 of the driving vehicle 20. Therefore, the movement route information of the emergency vehicle 50 is displayed on the navigation terminal of the driving vehicle 20 only when the driving vehicle 20 enters a range such as a radius of 100 meters or 200 meters from the emergency vehicle 50. .

In addition, when an emergency situation occurs during operation of the emergency vehicle 50, for example, road construction, fire, assembly, or cultural event on the movement route, the emergency vehicle 50 controls the emergency situation information to be centrally controlled. The central control center 30 transmits directly to the navigation terminal 10 of the driving vehicle 20 or the central control center 30 transmits the accident information to the GPS satellite 40 again. By transmitting the GPS satellite 40 to the navigation terminal 10 of the driving vehicle, the accident situation information is received by the navigation terminal 10 of the driving vehicle 20 passing through the periphery of the road where the sudden situation occurred. . When the emergency situation information is received in the navigation terminal 10 of the driving vehicle 20, the driver is notified of the fact by an alarm sound and the like, and the driving vehicle is searched for a detour route while displaying the location on the map of the navigation terminal. Make sure that you can bypass the road where the accident happened.

The transmission of such a sudden occurrence is also possible for a general driving vehicle 20, but only to an emergency vehicle 50 approved by a government office or the like in order to prevent problems such as false transmission for the accuracy of a sudden transmission or for personal reasons. It is preferable to limit.

Here, a brief summary of the operation of the present invention with reference to FIG.

While the driving vehicle 20 searches for the movement route to the destination with the navigation terminal 10 and is operating normally along the route (S100), the movement route information of the emergency vehicle 50 is transmitted to the navigation terminal 10. When received (S200), the navigation terminal 10 compares whether the distance between the emergency vehicle 50 and the driving vehicle 20 is within the reference distance (R) (S300). If the moving distance of the emergency vehicle 50 is the same as that of the driving vehicle 20, it is determined whether the moving distance of the emergency vehicle 50 is the same (S400).

If the movement route of the emergency vehicle 50 and the movement route of the driving vehicle 20 are the same, the navigation terminal 10 of the driving vehicle 20 searches for a detour route (S500), and if not the same, continues normal operation (S600). Do it.

On the other hand, when the distance between the driving vehicle 20 and the emergency vehicle 50 is out of the reference distance (R), the driving vehicle 20 continues normal operation (S600).
