Fatigue drive prompting device

Abstract

The disclosed device is in use for preventing driver from driving car in fatigue state such as unfixed hands to cause driving accident. The device includes following parts: car electrical source for supplying power source for the device; potential device for transforming voltage of car electrical source to desired voltages; induction set for inducting contacting pressure between hands and steering wheel; timing device capable of sending signal to the caution unit according to prearranged adjustable time; control circuit for processing relation of sensor signal; sound device for providing caution voice after receiving control signal and caution voice having been recorded. The sound device includes sound circuit and sound-producing device. In the invention, sensor installed on steering wheel sends signal to the voice caution unit, which sends control signal to driver.

Description

technical field

[0001] The invention relates to a safe driving device installed on a vehicle that conforms to human psychology, and in particular relates to a kind of inert state shown by the human body that causes hand relaxation when driving is fatigued, causing a sensor mounted on the steering wheel to send a signal to a voice reminder device, The voice reminder device sends a warning signal to the driver to ensure the reminder device for driving safety. Background technique

[0002] In traffic accidents, the proportion of accidents caused by fatigue driving is relatively large. According to statistics, the traffic accidents caused by the above reasons account for more than 50%. Unresponsive, if the driver is not reminded in time at this time, traffic accidents are likely to occur. Although many people at home and abroad have done relevant research, the cost is relatively high. The United States has developed an infrared eye scanner. When the lens is aimed at the driver...
