Electrical stimulation anti-fatigue system and control method

Abstract

The invention discloses an electrical stimulation anti-fatigue system and a control method. The method includes the following steps: adopting a fatigue state detection module to detect a driver fatigue state and feeding the detected driver fatigue state information back to a control module; adopting the control module for matching control signals according to the received driver fatigue state information, and transmitting the control signals to an electrical stimulation module; then adopting the electrical stimulation module arranged on a driver seat to generate stimulation current for electrical stimulation to a driver as per the received control signals; applying electric pulses to skin of the driver through the electrical stimulation module, so as to utilize current flowing through theelectrodes to stimulate a contact receptor in the skin for operation, besides, the driver under fatigue state is low in perception to outside signals, yet electrical stimulation can directly acts on human nerves, and is easier to be perceived by human brains, so that the driver is kept in a waking state, and the device is simple in structure and convenient to wear and has obvious stimulation 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
