System and method for assisting with safe driving, computer program for assisting with safe driving, storage medium upon which the computer program is stored, and Navigation Device
First Claim
1. A safe driving support system comprising:
- a first memory that stores traffic regulation data on a traffic regulation relating to lane changing in association with a road;
a host vehicle position identifying device that identifies a position of a host vehicle on a guided route;
a comparing device that compares the position of the host vehicle identified by said host vehicle position identifying device with the traffic regulation data;
an output device that produces, based on a result produced by said comparing device, an output to an effect that the traffic regulation is applied to a road on which the vehicle is travelling on the guided route or a road ahead of the road on which the vehicle is travelling on the guided route;
a speed comparing device that compares a speed of the host vehicle with a predetermined first threshold speed; and
a vehicle recognizing device that is provided in the host vehicle and recognizes a vehicle running ahead of the host vehicle, whereinsaid output device is operated when the speed of the host vehicle is lower than the first threshold speed and when said vehicle recognizing device recognizes a vehicle that runs ahead of the host vehicle.

Abstract
Disclosed is a system and method that offer improved assistance with safe driving using navigation devices, incorporating traffic regulations pertaining to route changes into guidance offered by the navigation devices. The system comprises a traffic regulations data memory (21), which associates, with roadways, data on traffic regulations pertaining to route changes, and stores the data so associated, an onboard vehicle locator (11), which locates the driver'"'"'s vehicle upon the suggested route, a comparison unit (31), which compares the location of the driver'"'"'s vehicle, as located by the onboard vehicle locator (11), with the traffic regulations data, and an output unit (40), which outputs, based on the determination made by the comparison unit (31), either information that driving regulations apply upon the road currently being traveled, as part of the suggested route, or that driving regulations apply upon roads ahead of the road currently being traveled, again, as part of the suggested route.

7. A safe driving support method using a navigation system including a first memory that stores traffic regulation data on a traffic regulation relating to lane changing in association with a road, and a host vehicle position identifying device that identifies a position of a host vehicle on a guided route, the method comprising:
-
comparing the position of the host vehicle identified by said host vehicle position identifying device with the traffic regulation data; producing, based on a result of the comparing, an output to an effect that the traffic regulation is applied to a road on which the vehicle is travelling on the guided route or a road ahead of the road on which the vehicle is travelling on the guided route; comparing a speed of the host vehicle with a predetermined first threshold speed; and
,recognizing a vehicle running ahead of the host vehicle by a vehicle recognizing device provided in the host vehicle, wherein the producing of an output is performed when the speed of the host vehicle is lower than the first threshold speed and when a vehicle that runs ahead of the host vehicle is recognized in the recognizing of a vehicle. - View Dependent Claims (8, 9, 10, 11, 12)

13. A computer readable medium that contains programming for causing a computer system to function as:
-
a first memory that stores traffic regulation data on a traffic regulation relating to lane changing in association with a road; a host vehicle position identifying device that identifies a position of a host vehicle on a guided route; a comparing device that compares the position of the host vehicle identified by said host vehicle position identifying device with the traffic regulation data; an output device that produces, based on a result produced by said comparing device, an output to an effect that the traffic regulation is applied to a road on which the vehicle is travelling on the guided route or a road ahead of the road on which the vehicle is travelling on the guided route; a speed comparing device that compares a speed of the host vehicle with a predetermined first threshold speed; and a vehicle recognizing device that is provided in the host vehicle and recognizes a vehicle running ahead of the host vehicle, wherein said output device is operated when the speed of the host vehicle is lower than the first threshold speed and when said vehicle recognizing device recognizes a vehicle that runs ahead of the host vehicle. - View Dependent Claims (14, 15, 16, 17, 18)
