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...
