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 displaying the current position of a vehicle on a road map displayed on a screen and guiding the vehicle to travel.

[0002]

2. Description of the Related Art Conventionally, in a vehicle navigation apparatus of this type, information on traffic rules corresponding to each road on a road map is stored in advance, and information corresponding to the road on which the vehicle is currently traveling is stored. A system has been developed that obtains information on traffic rules, detects that the vehicle is in violation of the traffic rules based on the current driving condition of the vehicle, and issues an alarm to that effect (Japanese Patent Laid-Open No. Sho 62-62). No. 154098 and JP-A-5-11700).

[0003]

The problem to be solved is that simply issuing a traffic rule violation alarm often causes a driver to recognize a traffic rule specified by a traffic sign or the like. Considering the lack of protection, it is not enough to deal with traffic rule violations.

Further, if an alarm is issued after a traffic rule violation is actually detected, the warning will be lost at a later time because the traffic rules must be observed.

[0005]

SUMMARY OF THE INVENTION The present invention is intended to enable a driver to be aware of the seriousness of a traffic rule violation in the event of a traffic rule violation and to more effectively appeal for compliance with the traffic rules.
Corresponding to each road on the road map used for navigation, not only the traffic rule information but also the penalty rule information of the traffic rule violation is stored in advance, and when a traffic rule violation is detected, The infringement and penalties are reported.

In order to prevent traffic rule violations, the present invention predicts traffic rule violations based on the current operating condition of the vehicle and determines the contents of the predicted traffic rule violations and penalties. I am trying to inform you.
