Abstract

A device using existing standard yellow indicator lights to indicate deceleration while maintaining the current functions of the hazard warning lights, which are given absolute priority, and of the flashing indicator lights, which are given priority on the appropriate side while the other side remains in use for signalling deceleration. The yellow indicator lights signal deceleration by lighting up non-intermittently by means of a contactor placed on the acceleration control system and actuated when the latter returns to zero. Given that side lights and brake lights are often one and the same, and that the time lapse without external indication between releasing the accelerator and braking is often critical, this system is designed to prevent many fatal accidents.

Description

DEVICE FOR SIGNALING DETECTION OF ROAD VEHICLES BY THE USE OF EXISTING AND APPROVED ORANGE LAMPS.

The present invention relates to a road safety device allowing the fixed lighting of the orange lights already existing on vehicles driving on the road for the purpose of signaling decelerations and drawing attention before braking, in order to avoid accidents often. lethal while retaining the current functions of these priority lights in the following order:

- Distress signals: total priority

- Flashing light for priority direction change on the requested side. The unsolicited side remaining available for deceleration signaling if necessary. Whatever the chronological order of control of the lights, the priorities will remain the same.

Any system giving the results mentioned above will be considered a copy.

Position lights and brake lights have been red for a long time. There are even some vehicles where the brake light and the position light are in the same vein, only the intensity of the bulb changes, when braking, which is even more dangerous. The eyes and the brain get used to red, when braking attention is not aroused by a change of color, it is often the accident.

In addition, many drivers, when approaching a dangerous point, are led to considerably reduce their speed by using only the engine brake without touching the hydraulic brake; in this case the deceleration signaling is zero. There are many other circumstances which show that deceleration signals can prevent accidents and save lives.

Example:

Decelerations and braking were never signaled by the front lights. However, when one vehicle duplicates another, oncoming road users would often like to know if this vehicle ends its overtaking or if it releases the accelerator with the intention of folding back due to lack of power or mechanical failure. Countless other examples could be cited.

The device according to the invention overcomes these dangerous drawbacks. Indeed every time the heater -feur will release the accelerator, the orange front and rear lights will come on. Any driver, necessarily letting go of the accelerator before braking, the orange lights will always precede the stops.

Any vehicle stopped for any reason whatsoever (traffic jam, accident, etc.) must have the orange lights on.

Any vehicle slowing down or downshifting with or without braking must have the orange lights on, which will make the intentions of the drivers of the vehicles followed or crossed more noticeable.

The system according to the invention will be incorporated between the original installation and the flashing unit.

Plate N ° 1 describes the system itself.

Plate Nº 2 describes the external connections.

The system consists of:

- two relays with three contacts closed at rest (R1 - R2)

- a relay with a contact closed at rest (R3)

- a relay with an open contact at rest (R4)

- fourteen diodes - fifteen male plugs

- a protective case and a fixing.

It is obvious that the electrical part must be appropriate to the vehicle voltage (6 volts - 12 volts - 24 volts)

The control for the decelerating lights will be placed in the most convenient location for the vehicle manufacturer or the installer on vehicles already in circulation.

Example: - on the accelerator pedal, on the carburetor or on the wheelhouse, on the injection pump or wheelhouse.

The system works as follows:

1 ° - the action of the button (12) for controlling the hazard warning lights (contact closed) will give the positive (permanent battery) at (B) which will power the flashing unit (20) (output L) and will cause the relay ( R3) which will open the contact (G1) cutting the positive (coming from the ignition key) of the common of the direction indicator control (13) output (D) and of the relay (R4) so that the distress will have full priority.

2 ° - The button (12) for controlling the hazard warning lights at rest (contact open), the action of the lever (13) for controlling the flashing lights on the left side, will provide the positive (input C) which will power the flashing unit (20) output (L) and will cause the relay (R2) to stick, this will open the contacts (C6 - C7- C8)

(C6) will cut the return of the distress indicator light (21) output (M), coming from the flashing central (20) input (N)

(C8) will cut the fixed deceleration ignition on the left side (14) output (P) supplied by the relay (R4) contact (C2), (C7) will cut the flashing on the right side (18) output (K) supplied by the control unit flashing (20) input (0).

3 ° - The button (12) for controlling the hazard lights at rest (contact open), the action of the lever (13) for controlling the right-hand direction indicators will provide the positive (input E) which will power the flashing unit (20 ) output (L) and will glue the relay (R1), it will open the contacts (C3 - C4 - C5). (C3) will cut off the return of the distress light (21) (output M), coming from the flashing central (20) input (N).

(C5) will cut the fixed deceleration ignition on the right side (18) (output K) supplied by the relay (R4) contact (C2), (C4) will cut the flashing on the left side (14) (output F) supplied by the control unit flashing (20) input (0).

4 ° - The button (12) for controlling the hazard lights at rest (contact open), the contact (19) closed by deceleration will provide the negative (input J) which will cause the relay (R4) to stick, it will close the contact (C2) which will light both sides (14 and 18) or the side remaining free (14 or 18) in fixed deceleration lights. In this way, directional flashing will have priority over the deceleration lights.

The indicator returns can be coupled in the case of a single indicator (outputs G and I).

In the case of specific left or right direction change indicators, use the output (G) for the left indicator (15) and the output (I) for the right indicator (17).

The input and output terminals will be marked with (A to O) which corresponds to:

- With positive input provided by the ignition key (11)

- B input of the direct battery positive (10) provided by the closure of the contact (12) for controlling the hazard warning lights. - G Return of the positive from the direction indicator lever (13) actuated on the left side.

- D positive output going to the common direction indicator lever (13)

- E positive feedback from the direction indicator lever (13) actuated on the right side

- P positive output on the left side flashing lights (14)

- G positive output going to the indicator on the left side (15)

- H connected to ground (16)

- I positive output going to the indicator on the right side (17)

- J earth return from the deceleration contact (19)

- X positive output going to the right side flashing light (18)

- The positive output flashing central power supply (20)

- M positive output going to the hazard warning light (21)

- N alternating positive return for distress indicator (21) coming from the flashing unit (20)

- O alternating positive feedback for the flashing lights coming from the flashing unit (20)

For each input and output, the section of conductor wires connecting to the existing installation must be specified on the connection plan supplied with the system.

. In some cases of a flashing unit with a single alternating output, the inputs (Net 0) will both be connected to this so-called alternating output.

The device according to the invention is particularly intended to equip all vehicles traveling on the road having orange lights.
