An electrical stimulation anti-fatigue system and control method

Abstract

The invention discloses an electrical stimulation anti-fatigue system and a control method. A fatigue state detection module is used to detect the driver's fatigue state, and the detected driver's fatigue state information is fed back to the control module. The state information matches the control signal, and transmits the control signal to the electrical stimulation module, and then uses the electrical stimulation module set on the driver's seat to generate a stimulating current to stimulate the driver according to the received control signal. Electric pulses are applied to the driver's skin, so that the current flowing through the electrodes can be used to stimulate the tactile receptors in the skin to work. At the same time, because the driver's ability to perceive external signals is reduced in a fatigued state, the electrical stimulation can directly act on the skin. The human nerves and the brain are easier to perceive, so as to achieve the purpose of keeping the driver awake. The device has a simple structure, is easy to wear, and has an obvious stimulating effect.

Description

technical field [0001] The invention belongs to the field of automobile active safety, and in particular relates to an electric stimulation anti-fatigue system and a control method. Background technique [0002] Fatigue driving is a major safety hazard in the field of road traffic. Drivers are self-fatigued due to factors such as long-time driving, driving at night and early morning, and lack of sleep. Fatigue will reduce the driver's attention, increase the driver's reaction time, and affect driving safety. Therefore, under the condition that the recognition of the fatigue state is completed, how to keep the driver awake, that is, to adopt a reasonable and effective method to wake up the driver in the fatigue state, is of great significance. Commonly used driving fatigue detection methods include detection based on driver's physiological characteristics, detection based on driver behavior characteristics, detection based on vehicle behavior characteristics, and detection ...

AI Technical Summary

Problems solved by technology

The existing incentive methods mostly use buzzer (sound stimulation), light alarm (light stimulation), vibrator (vibration stimulation), or mainly rely on the driver's own consciousness and rely on refreshing drugs or drinks to stimulate the driver, so that the driving Drivers stay awake, but the effect is not good. For long-term use of refreshing food, it will not only cause physical damage to the driver, but even cause the driver’s resistance to drugs; will decline, so the existing anti-fatigue devices have the disadvantages of insufficient reminders and limited prevention, which lead to the shortcomings of not being able to keep the driver awake.

In addition, the existing anti-fatigue devices, such as anti-fatigue glasses and anti-fatigue seats, all need to be worn by the driver or have a huge change to the device in the car, so it is extremely inconvenient to apply to existing vehicles
