Abstract

Safety device for warning the driver of a motor vehicle of a reduction in his perception by means of vibrators (101) fitted into the driving seat, these being connected to the battery (25) of the vehicle if pressure by the driver fingers on the driving wheel (20) is lessened or if there has been too great a reduction in safety distance as signalled by a modulated wave radar with an antenna (30) situated on the front of the vehicle.

Description

Safety device producing vibrations in the seat to warn drivers of motor vehicles when their attention has lessened
The invention concerns warning devices for drivers of motor vehicles.
Devices to prevent drivers of motor vehicles from falling victims to momentary attacks of sleepiness are already widely used. For maintaining control over a motor vehicle the essential parts of a driver's body are hands and eyes: the hands are constantly on the driving wheel to adapt the vehicle to changing road and traffic conditions seen by the eyes.
For this reason the safety devices at present known give warning if hand control of the driving wheel slackens or if the eyelids tend to close because the driver is about to fall asleep or has done so.
If either of these situations occur an acoustic warning is given.
Hand grip on the driving wheel is controlled by closure of a set of electric switches in those parts of the wheel held by the hand. The eyelids are kept open by a small telecamera directed towards the driver's face.
A drawback to the acoustic signal is that, if turned on low, it may not be heard in time by the driver partly because of the noise made .by surrounding traffic while, if turned up to high volume, it might startle him if drowsy and cause an uncontrolled reaction.
The above device avoids these drawbacks as will now be explained. Subject of the invention is a safety device to warn drivers of motor vehicles if their perception is becoming lessened.
Lessening of perception is brought to the driver's notice by vibrators placed in the driving seat. These vibrators automatically connect up to the vehicle's battery if hand pressure on the driving wheel lessens or if the distance from a nearby vehicle becomes too short for safety.
Inside the frontal lateral arcs of the driving wheel, where the driver's hands usually exert most pressure, both when driving on a straight road or when rounding a bend, are strips of push buttons placed in front of two electric conductors set side by side and continuing along the whole of said arcs.
If none of these push buttons are being pressed by the driver's hands, electric feed to an electromagnetic switch ceases, as a result of which, and under pressure from a spring, an electric circuit between the battery and the vibrators closes.
There are preferably four push-button strips, placed in pairs on the two frontal lateral arcs of the wheel respectively.
Reduction in vehicle-to-vehicle safety distance closes the electric circuit between the vehicle's battery and the vibrators by means of an electronic control unit connected to a modulated-wave radar with an antenna on the front of the vehicle.
The control unit comprises a circuit with a knob for adjusting safety distances taking account of environmental factors, such as fog. In one type of execution the radar comprises a diplexer, a mixer, an oscillator, an amplifier and a transmitter.
Advantageously the vibrators are situated one set beside another between layers of padding, chosen to ensure comfort for the driver but also to make sure that a warning signal cannot fail to be noted. A switch on the driving wheel turns on the safety device after the driver has begun to press at least one of the push-button strips mounted on it. The vibrators may be mechanical, electric or electronic as preferred.
Advantageously a visualizer indicates the distance needed for stopping the vehicle according to its speed.
The vibrators can be mounted actually inside the driver's seat or else inside a cushion placed on the seat.
The invention offers evident advantages.
The degree of perception a driver needs for maximum efficiency concerns driving trajectories as well as the safety distance between the vehicle and any kind of obstacle, or environmental condition, such another vehicle ahead or the presence of fog, such perception being ensured not only by the driver's own vigilance but also in relation to road and traffic conditions.
Warning of any lessening of perception is given in what might be called a physiological manner, avoiding the unpleasant sensations produced by acoustic warnings, which may be inadequate because drowned by noise of traffic or unnoticed due to the driver's own defective hearing, or else may be counterproductive because of being far too loud and startling the driver.
Given its simplicity and the adoption of reliably tested components, the device described can be fitted to any kind of motor vehicle.
Characteristics and purposes of the disclosure will be made still clearer by the following examples of its execution illustrated by diagrammatically drawn figures.

Fig. 2 Motor vehicle as above, internal perspective of the dashboard and front seats, showing an electromagnetic switch on the driving wheel, and the cushion with vibrators. Fig. 3 Diagram of components of an electronic box for radar, with control and operating panel. Fig. 4 Diagram of electric circuits between driving wheel, radar, electronic box, battery and cushion with vibrators.
Fig. 5 Diagram of the electromagnetic switch, open.
Fig. 6 Diagram of the electromagnetic switch, closed. The motor vehicle 10 presents the bonnet 11 , with front section 12, battery 15, seats 25, 26, driving wheel 20, radar antenna 30 and electronic box 35.
Inside the cushion 100 (Fig. 4) on the front seat 25, are the electronic vibrators 101 operated from the battery 15. The driving wheel 20 presents arched oblong push-button strips 60-
63, mounted inside its anterior sections 21 and 22, at the position where the fingers hold it.
The push-button strips comprise springs that exert outward pressure, and contacts, not shown for simplicity, pressure by the fingers during normal use of the driving wheel overcoming the pressure from said springs and closing the electric circuit between the electrodes 70 and
71 placed inside, indicated by a dotted line.
The driving wheel carries a device 75 with electromagnetic switch connected, by conductors 72, 73 and by the pull box 74, to the electrodes 70, 71 and by conductors 85-87 to the battery 15 and to circuits 95,96 of the electric vibrators 101 inside the cushion 100.
In particular said electromagnetic switch 75 comprises a magnet 105, a winding 106 and two contacts 107,108, connectable one to another by a mobile bridge 110 under pressure from a spring 111 acting in the direction opposite to attraction by the magnet when the winding is closed in an electric circuit.
The first electrode 70 on the driving wheel is connected through the conductor 73 to the first 107 of the two contacts of the switch and through the conductor 85 to a first pole of the vehicle's battery 15. The second contact 108 of the switch is connected through the conductor 86 to the first end of the electric circuit of the vibrators. The first end of the winding 106 is connected through the conductor 72 to the second electrode 71 of the driving wheel while its second end is connected through the conductor 87 to the second end of the electric circuit of the vibrators and to the second pole of the battery. Said device 75 can be put into operation by the switch 76 also placed on the driving wheel.
When the circuit, with electrodes 70, 71 , on the driving wheel, is. not closed by at least one push-button strip 60-63, electric feed to the electromagnetic switch ceases; as a result, this closes the electric circuit between the battery and vibrators 101 in the cushion 100.
The conductors 85, 86 are similarly connected through the shunts 80, 81 to the electronic control unit housed in the box 35. The radar (Fig. 2) comprises an antenna 30, diplexer 40 joined to said antenna 30 by the wire 31 , mixer 41 , oscillator 42, amplifier 43 and transmitter 44.
In front of the antenna 30 are arrows VA showing the departing wave and arrows VA + VR showing the departing and returning waves. These departing and returning waves are also shown in the connections between mixer 41 , amplifier 43, and at the oscillator 42. The signals from the radar 30, 40-44 are processed by the control panel 50 with regulator an knob 52 for establishing an electronic threshold indicated by the needle of the measurer 51 and corresponding to the chosen safety distance. When the driver sets off, manual pressure on the wheel closing the electric circuit between the conductors 70, 71 , the alarm device can be turned on by means of the switch 76.
On the journey, whenever hand grip on any one of the push-button strips 60-63 is lessened due to drowsiness or inattention, or when for inattention, fog or poor visbility, the safety distance is reduced too far, the electric circuit closes between the battery 15 and vibrators 100 in the seat 25 warning the driver and preventing- drowsiness, or waking him up if already asleep.
