Embodiment Construction

[0017] This "early warning system" equipment is composed of infrared cameras, video image sensors, electrophysiological information collectors, signal processors, warning signal generators, control car signal output parts, etc., such as figure 1 Shown in the block diagram.

[0018] 1. The idea of ​​the invention of the "early warning system" equipment

[0019] The hardware module and signal analysis and processing module, control signal module, and warning signal will detect the facial state (pupil size, eyelid closure frequency, eyelid closure time, yawn mouth shape, etc.), heart rate, and EEG information when the car driver is drowsy while driving. The equipment system composed of modules is called the driver fatigue warning system equipment system. As long as there are equipment or devices similar to the design concept of the "early warning system", they do not exceed the protection scope of the present invention.

Abstract

A biological recognition method for prewarning the fatigue state of car driver features that the biologic information associated with fatigue, such as face information, cardiac rhythm and cerebroelectric wave, are sampled and then compared with their references to judge if the driver is in fatigue state. Its system is composed of the biologic signal sampling and recognizing unit and alarm unit. Said biolgoic signal sampling and recognizing unit comprises video image sensors, bioelectric information pick-up and signal processor.

Description

Technical field [0001] The invention relates to an automatic driving control of an automobile, in particular to an early warning system for motor vehicles by identifying driver fatigue through biological signals. Background technique [0002] It is an existing technology that involves auto-driving systems for automobiles, in which shaft angle encoders, torque motors, and action cylinders can be used to control the direction and rotation angle, driving speed, and braking. For example, Chinese patent application 98122574.8 relates to a car automatic driving system, which uses a binocular camera system to automatically collect road condition information within 1-200m in front of the car: ground markings, isolation belts, anti-collision guardrails, lane marking identification, roadblocks; number of motor vehicles, Lane distribution, distance, relative speed and road sign information. System software automatic decision-making: car speed, car direction and posi...
