Definitions

  • the present invention relates to warning systems, and is particularly concerned with providing a warning system to alert motorists approaching traffic hazards.
  • the present invention seeks to provide a system whereby a vehicle involved in a collision automatically sends a warning signal receivable by following traffic, warning drivers to slow down and stop.
  • a vehicle crash warning system comprises a transmitter unit linked to a crash sensor and a receiver unit capable of receiving signals from the transmitter, an alarm being activated by the receiver when a signal is received.
  • the transmitter unit is a relatively short range radio transmitter
  • the crash sensor may be a conventional inertia switching device operable on an abrupt acceleration or impact.
  • the crash sensor may be a switching device linked to the vehicle's bumper to detect deformation of the bumper, or movement of the bumper relative to the vehicle body.
  • a flexible fluid-filled tube may be attached to the vehicle's bumper bars, with a fluid-pressure operated switch to register impacts on the bumper bars.
  • the receiver unit is preferably a radio receiver tuned to the transmitter frequency, and advantageously includes circuitry to discriminate between a transmitter which is approaching the receiver and one which is receding therefrom, and to operate the alarm only when a transmitting transmitter is being approached.
  • a directional antenna is provided for the receiver so that only signals emanating from sources in front of the vehicle are registered.
  • an arc of about 90 o either side of the vehicle's centreline is covered by the receiver antenna.
  • the antenna for the transmitter part of the device is preferably omnidirectional, so that effective warning signals are transmitted from crashed vehicles irrespective of the direction in which the crashed vehicles face once stopped.
  • the installation comprises a crash warning unit 1 mounted for example to the vehicle's fascia.
  • the unit 1 houses a transmitter T, an inertia switch I sensitive to abrupt acceleration or deceleration of the vehicle in any direction, and a receiver unit R linked to an audible alarm 2 and a visual alarm 3 situated in the driver's compartment of the vehicle.
  • the power source for the transmitter, the receiver, and the alarm devices may be the vehicle's electrical system, or an independent source such as a battery may be provided.
  • the independent source may be a battery rechargeable from the vehicle's own system.
  • the receiver unit is preferably housed in the same enclosure as the transmitter, and has external connections to a transmitting aerial 4 and a receiving aerial 5.
  • the receiver R may include circuitry to discriminate between approaching and receding sources of transmission. This may be done either by sampling the signal strength at discrete intervals and comparing the strengths of successive signal samples, the alarm 2 being sounded if signal strength is found to be increasing, or by using a Doppler shift in the frequency of the transmission to discriminate between approaching and receding sources. It is implicit that the transmitters T of all the units in a system will be tuned to a predetermined frequency, thus making Doppler shift usable as a discriminating characteristic. Alternately, the radio signal from the transmitter T may be emitted as a train of discrete pulses at a set interval, and the shift of interval in the pulses will indicate an approaching source.
  • the system may be permanently installed in a vehicle and wired to the vehicle's electricity supply P.
  • the radio transmitter T When the vehicle is involved in a rapid deceleration such as in a crash, the radio transmitter T will be actuated by the inertia switch I and will commence transmission on the warning frequency, via the omnidirectional aerial 4.
  • the inertia switch I may be of conventional construction, and maybe identical to switches currently installed in fuel injected vehicles to cut off power to the fuel pump in the event of a crash. In such vehicles, use may be made of the existing inertia switch to control the transmitter T of a crash warning unit.
  • Vehicles approaching the crash site fitted with like warning units will pick up the warning radio signal via the aerial 5, and the receiver will activate the alarm devices 2 and 3, alerting the driver to the approaching hazard.
  • the range of the radio warning signal may be adjusted by controlling the power output of the transmitter T and/or by providing the receiver R with a threshold control so that only signals above a predetermined strength are considered.
  • the receiver circuitry can be simplified by omitting the discriminator circuits, if the aerial 5 of the receiver R is arranged to be a directional antenna 5 oriented to receive only signals emanating from a source in front of the receiving vehicle. In such an arrangement, vehicles 'downstream' of a crash site will not have their alarms activated since the signal sources will not be within the arc of detection of their receiving antennae 5.
  • different frequencies could be provided, for example Northbound drivers using a first frequency and Southbound drivers being assigned a second frequency.
  • selector controls 10 on the transmitter T and receiver R for the driver the appropriate transmission and reception frequency could be selected for each part of a journey as the driver negotiates the motorway network.
  • the transmitter T may be made directional so that signals are emitted only rearwardly from the vehicle.
  • signals are emitted only rearwardly from the vehicle.
  • the transmitter T may be activated by a switch S mounted on the vehicle body to detect impact.
  • a switch S mounted on the vehicle body to detect impact.
  • Such a switch may be closed by a deformation of the vehicle bumper 9, or may comprise a deformable tube filled with fluid and provided with a pressure operated switch to activate the tansmitter on impact.
  • a connection 6 to the vehicle's lighting circuit 7 may be made, so that the fitted vehicle's lights could be flashed to provide a visual indication that a crash site is being approached.
  • the brake lights would be operated, since operation of the hazard lights when in motion is dangerous in that it prevents direction signals from being given.
  • a self-contained portable warning unit may be provided.
  • Such a unit comprises a preferably fireproof and impact resistant enclosure containing the transmitter, receiver, crash sensor, power source and alarm devices and provided externally with controls for activating the unit (on/off switch), battery test indicator, and frequency selector if appropriate.
  • Such a unit could be carried by the driver and attached, for example by suction cups or adhesive pads, to a convenient point in the vehicle, to be activated when the vehicle is involved in a crash.
  • the power for the unit could alternatively be supplied from the vehicle's supply P, e.g. via the cigar lighter socket.
  • Both the portable and the permanently installed system may include a manual override switch 8, enabling the motorist to activate the transmitter even when no impact has occurred with his vehicle.
  • a timer may be included so that the duration of transmission of the warning signal is limited to a set time, for example five minutes. This will avoid overloading an area with radio transmissions which might interfere with communications by emergency services.
  • the alarm device such as a lamp or a horn may be operated proportionately to the strength of the received signal, so that for example the alarm sound increases in loundness as the crash site is approached.
  • the emergency services could monitor the frequency of transmission of the units, in order that the earliest possible arrival of police and ambulance services at the crash scene.
