DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle navigation system for providing guidance to a destination, and particularly to confirming that the vehicle is proceeding along a guidance route, or determining the direction of the guidance route at an intersection or the like. The present invention relates to a target display device which is capable of instantaneously recognizing the presence of a target in the middle of a guide route, which is important for judging the target, and which can immediately determine what the target is.

2. Description of the Related Art Conventionally, there has been known a navigation system for displaying a place name or the like near a current position of a vehicle on a display such as a CRT installed near a driver's seat of the vehicle and assisting the vehicle to travel to a destination. ing. In a navigation system, a driver sets a departure point and a destination, searches for a desired route from map data stored in advance, displays the route to the driver, and guides the driver to the destination.

[0003] In such a conventional apparatus, when facilities such as a post office and a gas station are provided in a guide route, these are displayed as a symbol as a target and provided for the convenience of the driver.

[0004]

However, when a target is displayed as a symbol, there is a case where the driver or the like cannot know what the target is unless the driver knows the meaning of the symbol. For example, if the user needs to make a right turn at an intersection with a gas station on the right side, the user must immediately determine on the display device that the target at the intersection is a gas station. However, if the gas station, which is the target, is indicated by a symbol, if the meaning of the symbol is not understood, the user passes the intersection before recognizing the presence of the target on the actual route. Also, even if the meaning of the symbol is known, if it cannot be instantaneously determined, it may pass through an intersection in the same way.

[0005] Accordingly, an object of the present invention is to provide a target display device in which the presence of a target displayed on a display device displaying a guide route is determined on an actual route even when the driver is driving. It is to be able to recognize instantly. Another purpose is to display the target so that it can be immediately determined.

[0006]

In order to solve the above-mentioned problems, a target object display device of the present invention stores map information and actual appearance information of a target object in a predetermined storage medium, and reads out the information from the storage medium. A display device for displaying the obtained map data and the actual appearance data of the target, and means for superimposing and displaying the actual appearance of the target existing on the map displayed on the display device on the map. It is characterized by having.

[0007] Further, at least one of display of a symbol and a name of the target and guidance by voice is added to the display of the actual appearance of the target.
