DESCRIPTIONS

of the industrial invention entitled: "Device for signaling imprudence in driving with automatic anti-bump indicators for respecting the safety distance"

Premise:

t vehicles in circulation, in full compliance with current legislation, are equipped with systems for signaling driving intentions, turn right. or on the left. and braking, but they lack any other equipment suitable for making their circulation safer. In fact, it should be noted that, in the specific sector, there have been no innovative interventions for over 30 years in spite of a growth in the fleet which, from the early 1960s to today, has grown from about three million to over 30 million vehicles.

Carelessness in driving is a frequent cause of road accidents that involve other motorists with the person responsible for the imprudence, who have not detected any notice of such dangerous behavior.

The automatic signaling of dangerous and imprudent behaviors, which occurs regardless of any intention of the driver, but even against his will, with an electronic tampering design system, guarantees the safety of driving of all vehicles and especially those which follow in the same direction.

Acceleration, deceleration and imprudence in driving are now elements of evaluation of the dynamic motion of the cars in front, entrusted exclusively to the competence and experience as well as to the reflexes of the driver. The possibility of visually detecting these elements would contribute to increasing traffic safety.

The patent that is illustrated below is based on a computer system that manages a microcontroller which, in addition to the purpose of highlighting imprudence in driving, also serves to signal the driving status to other drivers of the vehicles it crosses. In fact, the device can add up, in the memory block, the carelessness in driving committed by the motorist in a given sample time. Adding up the driving times, when the motorist commits the tenth recklessness, the device emits an intermittent signal on the warning light placed on the rear window and on the warning lights placed in the upper center of the windscreen, for the remainder of the sample time set at 2 hours driving. It is likely that the most imprudent motorists will be exposed for a longer time to the warning of carelessness in driving.

At the end of the aforementioned sample time, the device is proposed again for a new sum of imprudences in a subsequent sample time. Through this system, the Police are able to identify drivers who have committed various imprudences, even if they cannot be sanctioned, but which could indicate an altered psychological state or habitual illicit conduct (failure to pay for possession taxes, administrative concession, absence RCA covers, smooth tires, burnt out vehicle lights, etc.).

The system also has the function of contributing to the education of the motorist through compliance with good traffic rules that are valid to avoid the repressive intervention of the Police. The habit that can arise from this will certainly serve to increase prudence and education in driving, at first only to avoid the application of sanctions, at a later time for assuming an active cultural custom.

DEVICE DESCRIPTION

The present invention relates to a completely new device, revolutionary in the field of automobile driving, concrete for its industrial application for the purposes of the safety distance between all motor vehicles, of an inventive level because of great utility, low cost and capable of functioning correctly and intelligently, combining the main function of the title, in a single device managed by a single microcontroller, with other functions offered by single existing devices.

The microcontroller, computerized for the management of the program, takes control of three areas of activity:

1) Service;

2) Maintenance;

3) Tamper proof.

The SERVICE functions given by the device are the following:

1) warning of imprudence in driving, which is activated due to lack of safety distance and other cases subsequently mentioned;

2) "deceleration" signal;

3) "acceleration" signal;

4) automatic signaling of emergency braking (or busca braked);

5) automatic switching on of the position lights in the tunnel and the lowering of sunlight following a sudden storm or in the evening hours.

The device consists of a microcontroller control unit (1) Fig. 1 which, by means of contacts (brake button (1) Fig. 3, accelerator button (2-3) Fig. 3, reverse button (37) Fig. 6 , inertial magnetic sensor Fig. 4 and probe for the twilight function (1) Fig. 2), checks the time of the aforementioned functions and the time between one function and another and transmits them both to the driver who generated said functions ( through an optical and acoustic signal (2) Fig. 1 on the dashboard), and to other vehicles. who follow him (through the signaling devices already existing on the vehicle and on the additional rear one (3) Fig. 1 for functions 1, 2 and 3) and to the Police (on the upper and central position of the windscreen (4) Fig:, t for the same functions 1, 2 and 3)

The yellow light source, transmitted by the additional indicator placed on the rear window (3) Fig. 1 in synchrony with that of the indicator placed on the windscreen (4) Fig. 1, with different signaling modes, summarizes 3 service functions represented in the mode following:

1) the presence of the flashing light sign represents imprudence in driving;

2) the presence of the fixed light signal represents the deceleration;

3) the absence of the light signal (light off) represents acceleration.

The aforementioned signals are highlighted by the driver through the yellow LED (4) Fig. 2 of the front device (2) Fig. 1 located on the dashboard. As it happens, the choice of the yellow color is used for the recklessness indicators (3) and (4) Fig. 1, as this color has:

1) the advantage of the greater evidence of this luminescence in the most difficult conditions, such as fog banks;

2) the additional indication of the emergency, resulting from the signaling of imprudence in driving;

3} the additional indication of the direction resulting from deceleration and acceleration (which indicate the direction of travel of the vehicle).

The main function n. 1 understood in the title, as "control and signaling of imprudence in driving", is based, as an operating principle, on the activation times of the acceleration, deceleration and braking maneuvers.

The intervention times of the device, which characterize the "control and signaling of imprudence" function, occur when the driver of a vehicle, after 3 seconds and more of acceleration, immediately leaves the accelerator and in less than 600 milliseconds presses the brake pedal, giving rise to an intermittent optical signal (indicators (3) and (4) Fig. 1 and yellow led (4) Fig. 2 of the front device (2) Fig. 1 located on the dashboard) and acoustic ( buzzer (5) Fig. 2 of the front device (2) Fig. 1 located on the dashboard) lasting 6 seconds.

The imprudence will be detected even if during the acceleration phase (with the green LED on) the accelerator pedal is released for a time not exceeding 2.5 seconds and, in the subsequent acceleration phase included in a time equal to 1 second , the brake pedal is activated in less than 600 milliseconds.

This condition can occur when the safety distance has not been kept due to carelessness and carelessness in driving. The same signal is detected through the indicator placed at the top center of the windscreen (4) Fig. 1 which works in synchrony with the rear window (3) Fig. 1 and with the yellow LED, (4) Fig. 2 placed on the device in front of the dashboard.

The cases in which the aforementioned maneuver times occur (acceleration, deceleration and braking), which give rise to incorrect driving and, therefore, to a warning of imprudence, occur in the following examples:

• when in a column of moving vehicles (slow or fast), the driver of one of them gets too close to the car in front (not maintaining the necessary safety distance), to adapt to the speed of the car that precedes it, immediately releases the pedal from the accelerator and operates the brake pedal in less than 600 milliseconds (even without excessive pressure), giving rise to the imprudence signal; • when the driver, arriving at a traffic light, decides to stop with a delay, consequently he leaves the accelerator pedal and operates the brake pedal in less than 600 milliseconds (even without excessive pressure), it gives rise to the imprudence signal;

• when the driver of a motor vehicle decides to suddenly turn right or left of an intersection and release the accelerator pedal and operate the brake pedal in less than 600 milliseconds (even without excessive pressure), it gives rise to the warning imprudence;

• when the driver of a motor vehicle is driving in a state of drunkenness or is under the effect of drugs or, even more simply, is prey to falling asleep, or even for behaviors due to moods of particular excitement like, for example, that of a robber on the run. All hypothesized driving situations trigger the device.

The device counts the driving times which are added up regardless of the behavior of the driver who can suspend but not interrupt the count with switching on and off the car.

Adding the said driving times, when the motorist commits the tenth imprudence, the buzzer will emit a sound for a duration of 2 seconds and, from that moment, the front windscreen indicator (4) Fig. 1, the yellow LED of the device located on the dashboard (4) Fig. 2 and the rear warning light on the rear window (3) Fig. 1, will flash careless driving for the remainder of the sample time (set at 2 hours of driving), except for the deceleration phase which is signaled with a fixed light for 3 seconds. This function, through the aforementioned indicators, can be detected by the Police.

The intelligent device excludes the detection and signaling of imprudence for a time of 15 seconds when reversing. Therefore, when reverse gear is engaged, each time the accelerator is operated, there is a time of 15 seconds to carry out this maneuver; after this time, the imprudence function is restored in the same way as for the ordinary direction of travel.

Function no. 2 of the device, relating to deceleration, is signaled with a fixed yellow light on the same light source as the imprudence signal and is activated when the accelerator pedal is released according to the times indicated below. The switching on of the fixed deceleration light is determined by the acceleration time previously performed by the driver of a vehicle. For example, at low speed and heavy traffic, if the green acceleration led (3) Fig. 2 on the indicator positioned on the dashboard is lit from 0 to 3.9 seconds, if you have to change gear, you will have a timing of 2.5 seconds, sufficient to perform this maneuver (without prejudice to the acceleration signal). If, on the other hand, the acceleration lasts for a time between 3.9 and 20 seconds, when the accelerator pedal is released, the intervention time of the deceleration signal will be reduced logarithmically as shown in the following table:

I) from 4 to 6.9 seconds the intervention will be 2 seconds;

2) from 7 to 9.9 seconds the intervention will be 1.6 seconds;

3) from 10 to 15.9 seconds the intervention will be 0.8 seconds;

4) from 16 to 19.9 seconds the intervention will be 0.5 seconds.

After a period of more than 20 seconds of acceleration, when the pedal is released, the deceleration signal will be instantaneous (which is very useful on motorways and at high speeds).

The intelligent device excludes the detection of the logarithmic intervention of the deceleration signal if, after the first 600 milliseconds of deceleration, the brake pedal is activated, in this case the stop and deceleration signals will be seen at the same time.

Considering that the additional indicator (3) Fig. 1 is installed in the rear part of the vehicle (in the center of the rear window), it is possible to signal to the following vehicles, the deceleration, which is also visible to the driver of the vehicle. which is in third position in the same row Fig. 5, without the need to undergo a sudden braking, and the consequent speed regaining phase with an appropriate shifting which involves consumption of brakes and fuel. The same signal is detected through the indicator located at the top center of the windscreen which works in synchrony with the rear window of the rear window and with the yellow LED located on the device in front of the dashboard.

The driver of a motor vehicle, having to keep the safety distance, in order not to trigger the imprudence signal, will pay more attention in detecting the deceleration signal and, therefore, said device can also be configured as a "DRIVING EDUCATOR". The use of the device in question facilitates, among other things, the habit of having the right distance between one vehicle and another, which is all the more necessary in cases of fog, or other atmospheric alterations, where the deceleration signal is important.

Function no. 3 of the device, relating to acceleration, is indicated (with the light off) by the same light source that indicates imprudence and deceleration (with different signals) on the signaling device (3) Fig. 1 located on the rear window and on that of the windscreen ( 4) Fig. 1, while on the indicator (2) Fig. 1 in front of the dashboard, it is indicated by the green LED (3) Fig. 2. The acceleration function is signaled to the driver of the vehicle and to the car that it follows 3 seconds after the accelerator pedal is activated, in order to signal the actual movement of the vehicle. The realization of the button for the acceleration and deceleration signal was realized through the replacement of the idle screw (2) Fig. 3 on which rests the lever of the limit switch of the accelerator wire (3) Fig. 3, putting mass the body (4) Fig. 3 (throttle valve).

The aforementioned idle adjustment screw must be replaced with a plastic screw with a central pin made of conductive material, in order to cause an insulation between the limit switch lever (3) Fig. 3 and the idle adjustment screw (2 ) Fig. 3, when said lever is positioned in the acceleration state.

Function no. 4 of the device, relating to emergency braking (or sudden braking), is generated by an inertial magnetic sensor Fig. 4 which also acts in the event of a rear-end collision. The aforementioned device is constructively made from a DRY-REED bulb (1) Fig. 4, which when approached to the high base of a cylindrical magnet (2) Fig. 4, in the rest state will not be crossed by the flow of the force (5) Fig. 4, therefore the contacts of the bulb are not switched. Since the lower base of the magnet rests in attraction on a cylindrical iron support (4) Fig. 4 and held in the upper part by a helical spring (3) Fig. 4, when the motorist abruptly stops the vehicle, the mass of the magnet will move forward at the top due to inertia and will then be retracted by the retaining spring. This occurs because the attraction force of the magnet on the axis is greater than the traction force of the coil spring which holds the magnet. When the position of the magnet is brought forward, the magnetic flux lines cross the bulb causing the closure of the contact which will be analyzed by the microcontroller. Once the microcontroller has received the signal, it transmits an intermittent pulse, highlighted by the joint operation of the direction indicators placed on the dashboard and by all the external direction indicators, for a duration of 30 seconds. The aforesaid 30-second intermittent signal ceases automatically when the driver of the vehicle, after having performed an emergency braking, accelerates and resumes driving.

Function no. 5, relating to the switching on of the position lights, is signaled by the green light located on the dashboard and is activated by means of a photoresistor (1) Fig. 2 which, together with the disabling switch (2) Fig. 2 of the same function, are located on the indicator (2) Fig. 1 located on the dashboard of the vehicle.

The aforementioned function is activated by the microcontroller 10 seconds after the ignition is switched on to avoid the current absorption of the position lights during the starting phase of the car.

In normal vehicle operation, this function is activated automatically after 700 milliseconds from the darkening of the photoresistor, which can occur in the tunnel or in the event of a storm or decrease in sunlight (evening hours); while it is deactivated after 10 seconds from the moment in which the photoresistor receives a restoration of normal brightness.

The system does not create incompatibility with the normal MAINTENANCE work of the car, even without losing the data stored by the same (driving time, number of carelessness and checking the electric wire of the accelerator with the ignition off). In fact, it is necessary to exclude the device by means of a manual switch (42) Fig. 6 located in the control unit (1) Fig. 1, in order to carry out maintenance on the car. The present area of activity of the microcontroller, relating to maintenance, has been computerized by the software to allow maintenance of the car without incurring the inconvenience that the microcontroller can interpret a tampering with the system belonging to its control area (battery, switchboard positive , accelerator electric wire, imprudence signaling and stop signaling wire).

When the switch is reactivated, the device will signal the resumption of functionality with the flashing of the imprudence warning lights for 5 minutes.

Therefore, this 5-minute timed function is used, since the motorist, in order to be able to commit unreported imprudence, could turn off the system, but always, when it is reactivated both while running and stationary, the system will be signaled imprudence in a time of 5 minutes. The driver will only wait for this time to expire to resume normal driving with the car.

The imprudence signaling device, for the safety and educational purposes it aims at, is protected, by means of the ANTI-TAMPERING software program, from interventions that alter its functionality, excluding or reducing the detectability of carelessness in driving.

The perfect functionality of the accelerator signals, as mentioned in the "Service" paragraph, the acceleration and deceleration phases and, coupled with the brake, the imprudent phases. The system recognizes tampering with the accelerator which places it in a situation of constant acceleration or deceleration. In fact, after 60 minutes of constant acceleration, which in practice has no possibility of occurring, the system detects the tampering by no longer running the service program and signals the cause of the tampering with special self-diagnostic ieds. The same result comes from deceleration (ignition on without the car moving) for 115 minutes.

The summations of the times are not canceled if the driver deliberately turns off the general panel of the car. When switched on, the times already memorized are summed with the following ones.

The same self-diagnostic signal produces prolonged braking for 1 hour or no braking for 2 hours. Even when the ignition is off, the accelerator pedal is activated for more than 4 seconds and 15 times to detect tampering with the system and the consequent diagnostic signal.

The interruption of the ignition wire of the warning lights of the imprudence also generates a situation of tampering diagnosed by the system. In all cases of tampering, the microprocessor runs the anti-tampering program and blocks the functionality of each service, detected by the police due to the absence of any signaling while driving. To restore correct functionality, it will be necessary to resort to assistance centers, where it will be necessary to replace the microcontroller.

In this way a warning device is realized, of simple construction, low cost and efficient.

DESCRIPTION OF THE WIRING DIAGRAM

The wiring diagram, illustrated in Fig. 6. represents the connection modalities between the microcontroller (4) and the optical and acoustic terminals (24), (2) and (3).

The system is connected through two connectors to the peripheral devices (connector (21) and (22)).

The connector (21) connects the following devices:

- magnetic device (31) for detecting sudden braking; - rear (2) and front (3) optical signaling device of imprudence;

- wiring diagram (38) to be carried out on the car in connection with the device (1).

The connector (22) connects the optical and acoustic device (24) located on the dashboard, also managed by the device (1).

The device (1) is powered with 12 or 24 Volts voltage in an alternative way and with the simple replacement of the relays (17), (18), (19) and (20) and of the lamps for the signals of imprudence (2 ) and (3). Therefore it can be mounted on any type of vehicle, this is because the integrated circuits (4), (5) and (6) work with a continuous voltage of 5 Volts guaranteed by the stabilizer (8) which is calibrated for voltage from 6 to 36 Volts .

The device (1) thanks to the installation of the microcontroller (4) is able to simplify the hardware structure equipped as it is with a management software system which, using the integrated (5), (23) and (6), reduces the essential components with evident savings both in terms of cost and size.

The aforementioned ICs have the following characteristics: (5) represents an I / O multiplier;

- (23) represents a darlygton - RELAY DRIVER:

(6) is a tone generator for the buzzer (29).

The device (1) is decoupled from the car electrical system through the relays (17), (18) and (19) and the optocouplers (11), (12), (13), (15) and (16) .

The connection of the device (1) is powered by positive voltage through the power switch (42) connected to the fuse (34) of the wiring (38); this voltage supplies, through the appropriate relays, also the emergency lights (32), the position lights (33), and the imprudence indicators (2) and (3). At the same time the relay (20), powered by the positive of the car general panel (36), in addition to supplying power to the power relays, through the stabilizer (7) sends the ignition signal of the ignition panel to the microcontroller.

The anti-tampering function is guaranteed by the optocouplers (12), (13) and (15), while the optocoupler (16) is used to receive the signal from the magnetic device (31) which represents the sudden braking detector,

The optocoupler (11) by means of the reverse switch (37) excludes the detection of imprudence in reversing maneuvers, if these are contained within a maximum time of 15 seconds of continuous acceleration.

The optocoupler (12), through the button (35) of the brake pedal, detects the continuity or absence of the braking impulse, continued for 1 hour for the first or for 2 hours for the second, a condition that will be evaluated by the software computer system which act of tampering.

The photocoupler (13), through the accelerator pedal button, detects the acceleration or deceleration behaviors allowing the microcontroller to measure the times according to the times set by the software program.

With the ignition on (36), the acceleration continued continuously for 1 hour or the deceleration for 1 hour and 55 ', will be interpreted by the software system as acts of tampering with the electric wire of the accelerator.

With the ignition off (36), on the other hand, but with active voltage at the maintenance switch (42), if acceleration actions are exercised, the control by the microcontroller is activated for a period of 15 minutes, in which the higher accelerations are detected after 4 seconds and, at 15A acceleration, the microcontroller will signal tampering with the panel switch (36).

The optocoupler (15), through the rectifying bridge (9) connected to the lights (2) and (3) signaling the imprudence, checks their presence and the state of functionality, with the ignition on.

The control of the. the rectifier bridge (9) is exerted on the ground wire (through the lamps) and when this is interrupted for more than 15 minutes, the event is qualified as tampering. The tampering in question is signaled by the luminous combination of LEDs (39), (40) and (41).

The photoresistor (25), placed in the device (24) in front of the dashboard, when the sunlight falls, goes from a low resistive value to a very high resistive value, a condition for which the transistor (14) goes into conduction. This, detected by the microcontroller for a time exceeding 700 milliseconds, activates the switching on of the position lights (33), through the relay (18). The function can be excluded by activating the switch (26) which short-circuits the photoresistor.

Carelessness in driving, of any nature, detected by the microprocessor, is acoustically signaled to the driver of the vehicle via the buzzer (29), which receives the note signal of the integrated (6) (note generator) via the transistor ( 10).

In the device in front of the dashboard there are two LEDs, one green (28) and the other yellow (27), which indicate acceleration and deceleration. The yellow deceleration one works synchronously with the imprudence indicators (2) and (3).
