Abstract

A vehicle warning and control system and equipment is disclosed utilizing radio frequencies and the Doppler principle wherein one of the vehicle lights acts as the R.F. radiator, reflector, receiving antenna as well as an illuminator, and through standard circuitry supplies a warning signal or a brake activating signal.

Claims

1. In a radio frequency Doppler effect vehicle control system for controlling the distance of such vehicle relative to another object, a transmitting and receiving antenna system for said radio frequency comprising the filament and reflector of one of said vehicle lights.

2. The invention according to claim 1 wherein said filament and reflector are those of the left front headlight of an automobile.

3. The invention according to claim 1 wherein said control system comprises an alarm signal device.

4. The invention according to claim 3 wherein said alarm signal device comprises an audible alarm.

5. The invention according to claim 2 wherein the vehicle control system comprises a vehicle brake operating device.

6. A vehicle control system for a vehicle having a headlight including a filament and a reflector mounted thereon comprising a high frequency oscillator on such vehicle, a transmitting radiator of said high frequency comprising the filament of said headlight, a reflector for said radiator comprising the reflector of said headlight, said reflector and filament constituting the receiving antenna means, signal detecting and amplifying means connected to said receiving antenna means, and vehicle control means connected to said amplifying means.

7. The invention according to claim 6 wherein the oscillator comprises a continuous wave oscillator.

8. The invention according to claim 2 wherein the radio frequency is essentially the natural resonant frequency of the headlight filament.

9. The invention according to claim 2 wherein the radio frequency is of the order of 850 megahertz.

10. The invention according to claim 2 wherein the control system is operative for difference velocities of two vehicles going in the same direction between 5 and 90 feet per second.
