In a navigation device assisting a driver of a vehicle to drive safely by presenting accurate information at the right time what is going on around his/her vehicle, an obstacle detection part detects any obstacle with the help of external information monitored by an external monitor part. By utilizing the vehicle's current position detected by an input part and a position detection part, and map data stored in a map data storage part, a route selection part searches for a route to a destination. Based on thus found route, current position, map data, and the external information from the obstacle detection part, a guiding part performs route guidance to the destination. A map data arranging part refers to the map data, information from the obstacle detection part and the input part, and object model display information from the object model display information storage part, and arranges any applicable object model onto a map data space. A display accordingly displays guidance information together with the resulting map image. |

DETAILED DESCRIPTION Therefore, an object of the present invention is to provide a navigation device for helping the driver of a vehicle drive safely, without annoying the driver, by presenting him/her accurate information at the right time what is going on around his/her vehicle.
The present invention has the following features to attain the object above.
An aspect of the present invention is directed to a navigation device of a vehicle-mounted type for detecting the circumstances around a vehicle, and if considers warning a user is appropriate, arranging an applicable object model for display on a map image, and making a guidance to a destination.
In the present navigation device, an external monitor part monitors the circumstances around the vehicle, and outputs resulting monitor information.
Based on the monitor information, an obstacle detection part detects any obstacle observed outside of the vehicle, and outputs external information including position information of the obstacle.
Based on the external information, a guiding part determines if the obstacle requires the user's attention, and if requires, generates drive assistant information including the position information of the obstacle as in the external information.
Based on thus generated drive assistant information and object model display information for the obstacle, a map data arranging part creates an object model for arrangement on a map image.
Further, the guiding part generates guidance information including the resulting map image outputted from a map data arranging part in response to the route selected by a route selection part, the current position detected by a position detection part, and map data from a map data storage part.
Thus generated guidance information is displayed on a display part for the user.
These and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings
