Abstract

A device for detecting obstacles from a vehicle, comprising a transmitter (T) a receiver (R) operating within a suitable energetic wavelength, an integrator (I) for processing the reflected signals into a proximity signal, a display (D) and a sounder (S) for warning of proximity. Allowance is made for building the device into existing vehicle lighting and wiring assemblies, thereby reducing manufacturing modifications. Allowance is also made for signaling proximity either through the existing wiring to the display (D) or sounder (S). <IMAGE>

Description

method of detecting obstacles from a moving vehicle.
This invention relates to the automatic detection and indication of obstacles in the path of a moving vehicle.
The system comprises a transmitter (T), 2 receiver (R), an integrator (I), a display (D) and a sounder (S!. When the vehicle (V) is manoeuvring, particularly where visibility is impaired, energy remitted from transmitter T will reflect off an obstacle (0) and be received by receiver R. The strength.
and delay of the received signal can be compared cnd computed by integrator I to give an indication of relative proximity on display D and a warning through sounder S.
Although any portion of the energetic spectrum may be used, from sound through microwave to visible light, the example here will use infra red energy.
In a preferred and specific embodiment, the system is used in e vehicle for assisting parking and reversing. The tranrmitter T and receiver R are mountec together in â suitable position (eg the rear burner mounting) in a suitable housing (eg a reversing light). When the system is activated by a switch or by engaging 'reverse' gear, the transmitter T will start to emit infra-red light in e charcteristic pattern. When the emitted infra-re.d light strives an obstacle o (eg another vehicle) ? nortion of the energy will be reflect back and detected by receiver R. The integrator ill core the timing and or of te received signal to give the closeness of the obstacle 0 and will cause the display D to show the posItion. When the obstacle 0 is very close the sounder S will give a graded warning signal.
It is cluite possible, using modern methods of manufacture to produce a miniaturised version of the system which could be fitted in existing reversing lamp assembly. In this case communication to display D (which could be a clock) and/or sounder S (which could be the car radio) could be by means of a modulated signal via the existing vehicle wiring.

Claims (5)

1 A device for the detection of obstacles from a vehicle, where the transmitter (T) and receiver (R) may overate with any suitable energetic waveforms to effect reflected detection from such obstacles.
2 A device as in 1 above, where the resulting detection of such objects is processed within an integrator (I) to give details of proximity.
3 A device as in 1 & 2 above, where the output can then be used to drive a visible display (D! or audible sounder (S), thus warning of proximity.
4 A device as in 1,2 & 3 above, where it can be accommodated within an existing lamp assembly or wiring.
5 A device as in 1,2,3 & 4 above, where a modulated signal can be used to signal obstacle proximity to another device within the vehicle, either via the existing wiring or vi radiated signals.
