Patent ID: 7679499

Claim:
A warning system for use in a vehicle comprising: a detector that detects, as unsafe driving, a driving operation exceeding a safety standard and outputs a detection signal that indicates the detection of the unsafe driving; an interface unit that is connected to the detector; and an acquisition unit, in connection to the interface unit, that repeatedly identifies a current position of the vehicle, acquires the detection signal output from the detector through the interface unit, and records as unsafe location information, position information of the vehicle at a time of the unsafe driving based on an acquisition of the detection signal, wherein the detector acquires the current position identified by the acquisition unit through the interface unit, the detector outputs the detection signal including the current position as position information of the vehicle at the time when the unsafe driving is detected, the acquisition unit acquires and records the position information output by the detector through the interface unit as the unsafe location information, the acquisition unit provides a warning for a user based on a predetermined degree of closeness of any identified current position of the vehicle to any position information previously recorded as unsafe location information, and the acquisition unit prioritizes the identification of the current position of the vehicle higher than other processes including the recording of the unsafe location information.
