US 2011/0215951 A1 · 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

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.

Claims23

Dependent claims

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;
and
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. and
a speed comparing device that compares a speed of the host vehicle with a predetermined first threshold speed, wherein
said output device is operated when the speed of the host vehicle is lower than the first threshold speed.

4 more elements

A computer program 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;
and
a speed comparing device that compares a speed of the host vehicle with a predetermined first threshold speed, wherein
said output device is operated when the speed of the host vehicle is lower than the first threshold speed.
