Smart seat against a drunk driver

Smart seat against a drunk driver
Now not only a vigilant neighbor or a traffic police officer can detect a drunk driver at the wheel, but also a smart chair - a new development of Japanese scientists

Some models of modern cars are equipped with driver monitoring systems. With the help of cameras in the interior of the car and sensors on the steering wheel, you can easily analyze the condition of a person. Thus, information about facial expressions and the presence of eye contact can reveal signs of drowsiness or wakefulness.

Other, more advanced technologies also use external cameras. They "see" how the car behaves in a given lane, gives an alarm when the car starts to oscillate and wag on the roadway.

But the new development takes a completely different approach to the "body". Japanese researchers from the National Institute of Advanced Industrial Science and Technology insist that most smart car assistants have serious flaws. And the presence of internal or external monitoring cameras has nothing to do with it. The accuracy of the systems is affected by the time of day, precipitation, and so on. To make monitoring as accurate and independent of external factors as possible, technologists have created a "smart" car seat.

The feature of such a chair is the presence of heat-resistant sensors and pressure sensors. They determine the state of the driver: whether he sleeps at the wheel, how capable and mobile. To monitor the position of his body, sensors are installed in the back or seat of the chair. The information collected by the sensors shows the heart rate and respiration rate. Also, sensors allow you to monitor posture, deviations of the body to the sides, which can become a signal of an inadequate / sleepy state of a person.

Such a development can be used in a new, more advanced generation of cars. For example, if a self-driving car detects that its driver is asleep, intoxicated, and his vital signs indicate incapacity, then the car can automatically call an ambulance. Next, the vehicle “order” driver to stop. Special piezoelectric sensors work even at high temperatures, this provides a design to protect the system and ensure operation at temperatures up to 120 C.
