ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates an information system which informs a driver that a traveling vehicle is approaching a danger point.
Japanese Patent Provisional Publication No. (TOKUKAIHEI) 10-332409 discloses a conventional information system which informs previously-stored bad places for traffic accidents to a vehicle driver.
SUMMARY OF THE INVENTION
However, this conventional information system is arranged to previously store various information as to traffic accidents and to inform the stored information to the driver. Since the validity of such information varies according to driver's skill in driving, some drivers of high driving skill feel the information to be too much and some other drivers of low driving skill feel the information to be too little.
It is therefore an object of the present invention to provide an improved information system which provides optimum information according to driver's skill in driving to a driver.
An information system according to the present invention is for a vehicle and comprises a position detector, a traveling circumstance detector and a controller. The position detector detects a position of the vehicle with respect to the Earth. The traveling circumstance detector detects circumstantial information of the vehicle. The controller is connected to the position detector and the traveling circumstance detector. The controller is arranged to decide whether a quantity indicative of the circumstantial information of the vehicle is greater with a circumstance threshold, to store the position of the vehicle as a stored point when the controller decides that the quantity indicative of the circumstantial information is greater than the circumstance threshold, to decide whether a distance between the position of the vehicle and the stored point is shorter than a predetermined distance, and to output information indicative that the vehicle approaches the stored point when the controller decides that the distance is shorter than the predetermined distance.
