FR2871915A1 - Emergency and danger signaling method for e.g. vehicle, involves actuating lights and emergency system by following vehicles in order to permit drivers to anticipate braking, at reception of signal - Google Patents

Abstract

The method involves transmitting a signal towards following vehicles by an emitter of a vehicle, during validation of an input signal following an incident or a voluntary action. The signal from the vehicle is received by receivers of the following vehicles. Lights and emergency system are actuated by the following vehicles in order to permit drivers to anticipate braking, at the reception of the signal. An independent claim is also included for a device for implementing emergency and danger signaling method.

Description

Active safety system for vehicles and road interventions

  The present invention relates to a device that improves road safety. This device is both active and passive therefore makes the system effective.

  The current distress system is local. The driver must be constantly on the lookout, in all weather, visual information including the intensity of the rear lights of previous vehicles or a possible incident.

  When a vehicle is in difficulty, by deliberate action on the distress button, the lights start flashing and emit a small flash.

  The following vehicles only realize when visually they identify the problem. The perception of the event depends on the visibility.

  The device according to the invention overcomes this disadvantage.

  It is an active method of distress and danger signaling, for vehicles and boxes, equipped with a transmitter, a receiver, an indicator light, a sound equipment, an input for a signal d urgency, hazard warning lights and an adjustment knob and manual control characterized in that: - during the validation of the input signal following an incident or voluntary action, the transmitter of the vehicle transmits a signal to the following vehicles.

  the receiver of the vehicles receives the signal coming from the vehicle in difficulty or from the box.

  at the reception of the signal, the following vehicles trigger its lights and the distress system so as to allow the drivers to anticipate the braking.

  The object of the invention is to provide permanent and therefore more effective safety for any moving vehicle and persons working in the roadway.

  Each vehicle must be equipped with a set consisting of hazard warning lights, an indicator light inside the vehicle and placed in front, for example, of the driver among others, a buzzer at the vehicle interior and audible by the occupants, a radio transmitter and receiver, and / or infrared whose transmission length will be modulated according to the speed, the condition of the roadway, visibility and the importance of the desired security.

  The emission angle will be obtained according to the desired distance which itself is a function of the speed.

  2871915 2 The objective is to sweep only all lanes on one lane at a time and the preceding vehicles moving in the same direction.

  The triggering of the device can be voluntary by the action on a button or automatic sensor. It is connected to the sudden deceleration, shock sensors, to the triggering sensors of airbag safety systems.

  The reporting mode can be chosen. Either the light signal only or the sound signal only or the sound and light signal together.

  This device is used for road interventions; by firefighters, paramedics, emergency services, works, maintenance and road development services. The commissioning of the device in this case remains voluntary.

  By a manual action, an unexpected event, a bad sudden visibility, accident, unexpected obstacle, an event likely to cause a sudden deceleration causes the device to start.

  It simultaneously puts into service, the usual hazard lights associated with a sound and a light indicator inside the vehicle, plus an infrared ray emission and / or a radio wave. This emission is received by the following vehicles equipped with the device and scanned by waves and / or emitted rays.

  The frequency of the sound and the appearance of the light is inversely proportional to the distance between the place of emission and the place of reception. The closer we get to the scene of the incident, the faster the flashing.

  Radio transmissions and / or infrared signals will be in the form of a unidirectional, rearward-facing beam and will only cover later vehicles or those covered by the transmitted signal.

  The emission distance will vary from 0 to 500 meters and will depend on the speed. By way of nonlimiting example, speed settings of 50, 90, and 110 kilometers per hour for an emission distance of 50, 200 and 300 meters The trigger is voluntary by an action on a distress button or automatic by an incident caused by, low visibility, a wet pavement, an obstacle in the road, work, development, an accident, a sudden deceleration, the triggering of the airbags or sudden braking as a For example, the vehicle (A3) in distress emits signals received vehicles (B2), (B3), (C2) and (C3).

  In another context, the device housed in a housing or box (E), easily transportable and used if necessary to alert vehicles of the existence of work, intervention or modification of the roadway.

  Here for development work, the device placed in the housing (E) emits signals that are received by the vehicles (Al 1), (A21), (B21), and therefore makes the security more efficient. He shall notify all vehicles more than 500 meters of the existence of the work or the presence of an intervention within the marked area, the presence of an obstacle, or the modification of the roadway.

  The studs remain an additional signage.
