RU2478488C2 - Device to control driver functional state - Google Patents

Abstract

FIELD: transport.

SUBSTANCE: invention relates to automotive safety means. Transmitter transmits modulated IF signal to self-contained receiver fitted on driver's wrist. Said signal triggers vibratory bell in said receiver to be switched off by push button arranged at vehicle control panel. In case driver does not respond to said vibratory call, sound signal circuit and light alarm circuit relay contacts close. In case driver fails again to respond to said actions, uncontrolled vehicle is topped by forced brake system operation.

EFFECT: safe control over transport facility and higher traffic safety.

Description

The invention relates to road transport, in particular to safety equipment.

The most severe consequences are characterized by traffic accidents with a head-on collision of oncoming cars, and the speeds in intercity traffic are much higher than on city roads, therefore the consequences are more tragic here.

The cause of traffic accidents associated with driving into the oncoming lane on country roads is most often the driver’s sleep while driving (for example: http://yandex.ru/yandsearch?text=%D1%83%D1%81%D0 % BD% D1% 83% D0% BB +% D0% B7% D0% B0 +% D1% 80% D1% 83% D0% BB% D0% B5% D0% BC & lr = 193). A lulling effect on the driver is provided by a uniform landscape, a continuous monotonous movement in a single rhythm, which does not require any activity from him.

There are also possible cases of loss of consciousness by the driver while driving in fainting conditions, cardiovascular diseases, etc.

A device known is Stop Sleep (http://www.zr.ru/a/247537/), which helps the driver not to fall asleep while driving, but it does not provide for the forced stop of an uncontrolled vehicle in case of loss of consciousness by the driver.

In order to improve road safety due to the prevention of such traffic accidents, the claimed invention provides for the use of driver alertness monitoring devices in automobiles, mainly in buses and heavy vehicles carrying intercity communication (hereinafter referred to as TS).

The specified device comes into effect if there is no activity for a certain time on the part of the driver associated with shifting gears, braking or gaining speed, steering wheel turns.

The device is a transmitter installed in the vehicle’s dashboard, which periodically sends a modulated infrared signal, according to the principle of a television remote control, to an autonomous receiver, worn on the driver’s wrist, like a wristwatch. The power source of the wrist receiver is a battery similar to that used in mobile phones, with the possibility of recharging from the car’s network.

In the specified wrist receiver, a call is launched from the received signal, working in vibration mode, so as not to disturb the shift driver and passengers. The call will bring the driver out of a drowsy state and allow him to take timely measures to prevent departure to the oncoming lane.

To stop the call, you need to press the button located on the vehicle control panel so that the driver reaching for it is forced to change its position, which excludes the automatism of its actions. Pressing the button opens the contact in the transmitter, stopping the sending of the signal.

In the absence of a driver’s reaction to a vibration alert for a certain period of time, the relay contacts in the horn and vehicle alarm circuits are closed, attracting the attention of drivers of not only passing, but also oncoming cars. If even now the driver does not respond, the contact closes in the circuit of the coil of the solenoid for the forced operation of the brake system.

A vehicle stopped in a traffic lane with an audible signal and an alarm will turn on the attention of other road users who will call emergency services and provide first aid.

The closest in technical essence to the claimed invention are the USSR copyright certificate No. 680010 dated 08/15/1979, G08B 23/00, B60Q 9/00, B60T 7/14, USSR copyright certificate No. 246330 dated 06/11/1969, B60T 7/14 and copyright USSR certificate No. 703385 dated 12/15/1979, B60Q 9/00, G08B 23/00, B60T 7/14, which show devices for monitoring the functional state of a car driver.

The advantages of the claimed device are compactness and the absence of wired communication between the driver and the dashboard of the vehicle.

The technical result of the claimed invention is to improve road safety due to:

- use in the vehicle control system of vigilance of the driver;

- periodically checking the functional well-being of the driver and removing him from a drowsy state;

- stopping an uncontrolled vehicle with the help of forced operation of the brake system;

- timely warning of other traffic participants about an emergency on the road.

The use of a driver’s vigilance control device in a vehicle consists in periodically checking its functional state with the aim of removing it from a drowsy state, stopping an uncontrolled vehicle with the help of a forced brake system, and timely warning drivers of other vehicles of an emergency on the road.

New significant features of the claimed invention are:

- improving road safety;

- the use in the vehicle control system of vigilance of the driver;

- periodic check of the functional well-being of the driver and his removal from a drowsy state;

- stopping an uncontrolled vehicle with the help of a forced brake system;

- timely warning of other traffic participants about an emergency on the road.

These new essential features, together with the known ones, are necessary and sufficient to achieve a technical result in all cases to which the requested amount of legal protection applies.

The proposed technical solution is industrially applicable, has novelty, for a specialist it is not obvious from the prior art.

Claims (1)

A device for monitoring the functional state of a car driver, consisting of a transmitter supplying a modulated infrared signal to an autonomous receiver, worn on the driver’s wrist, characterized in that a vibrating alert is triggered from the received signal by the button located on the control panel of the vehicle in the specified receiver the driver’s lack of reaction to the vibration alert closes the relay contacts in the horn and light alarm circuits of the car, if after this reaction does not follow, the uncontrolled vehicle is stopped by means of forced operation of the brake system.
