Definitions

  • the present invention relates to a signal warning system and more particularly to an automatic signal warning system which activates the brake lights of vehicles.
  • warning system lights warn a following driver that the car immediately ahead is slowing down or braking.
  • the warning signal of a car further ahead of a following car cannot warn a following driver of a sudden slowdown or stop in the line of cars further ahead.
  • a signal warning system which comprises a receiver to be mounted on the front part of a given vehicle, said receiver being connected to an OR gate and a transmitter to be mounted on the rear part of the vehicle, said transmitter being connected to said OR gate, which is connected to the vehicle's existing electric brake light system.
  • a receiver 2 is mounted while at the rear end a transmitter 4 is mounted.
  • the transmitter will have to be of a directional type, probably a light transmitter in the infra-red range or similar, with an operating range of about 100 meters and an angular divergence of about ⁇ 15 o .
  • the signal from the brake switch will go through the OR gate 5 to activate the transmitter 4 mounted on the rear end of the vehicle, and the brake light.
  • Receiver 2 upon receiving the signal from the transmitter 4 will give a signal which will operate - through the OR gate 5 - both the brake light and the transmitter mounted on the rear side of the vehicle.
  • lorry A brakes In a practical operation, lorry A brakes.
  • the braking operation causes the transmitter 4 and the brake light to be activated.
  • the signal from the activated transmitter will activate the receiver in car B which is following car A. This in turn will cause the brake light of car B to be activated, and its transmitter.
  • This process will continue for all cars in a line, as long as the distance between any two cars is less than 100 meters. This is to say, that if there are 100 cars in a row, and car A pressed on the brake pedal, immediately all cars in the row will have their brake lights activated, each by the car in front of it, and in a matter of a fraction of a second.
