Abstract
ABSTRACT OF THE DISCLOSURE
This disclosure pertains to a vehicular safety device utilizing a fog sensing apparatus for detecting the presence of for immediately preceding the foremost portions of the vehicle.
When fog is detected, the braking system of the vehicle is gradually but forcibly brought into play reducing the speed of the vehicle to a preset maximum determined by a governor operated by the engine. A control wait is concurrently activated which causes the rearmost lamps of the vehicle intermittently to energize, and automatically altering the mode of operation of the headlamps of the vehicle for a time period equal to the continual sensing of fog.

Reid and United States Patent 3,716,822 issued February 13, 1973 to Y.Tsuruta all teach control of the speed of a motor vehicle responsive to the proximity and location of solid objects or leading vehicles located forward of the vehicle so protected.
A object of the instant invention is to provide a vehicular control responsive to th.e presence of fog immediately ~ -preceding the forwardmost portion of the vehicle.
In the present invention a fog sensor is installed at or near the front bumper of the vehicle responsive to fog patches 20 above the road bed immediately preceding the vicinity of the front portions of the vehicle. The fog sensor, when detecting the pre- .
sence of fog, activates a control box which in turn automatically applies the vehicle's~ braking system so that the speed of the :
vehicle is reduced and llmited to a speed determined by a preset governor attached to the engine. The control box simultaneously activates a high intensity rearmost signalling lamp system intermittently, for the period of time that fog is detected.
~' Z
Concurrent1y, and for the same duration, the headlamps of the vehicle are modified in mode of operation by either turning on ~og lamps or changing ~rom high to low beam. All vehicular controls, including the application of the emergency braking system and speed limiting devices, are turned off when fog is no longer detected.
Thus according to -the present invention,there is provided a vehicular safety device comprising fog detecting means for the detection of fog in the pathway of a vehicle, said fog detecting means carried by a frontmost portion of said vehicle, said fog detecting means utilizing rays emanating outwardly and forwardly from said vehicle directed over a roadway carrying said vehicle, said fog detecting means including means to detect said rays reflected from said fog when said fog is located in front of said vehicle and above said roadway, said fog detecting means for controlling apparatus means of said vehicle in a fog detected mode and a lack of fog detected mode, said fog detecting means being disposed in said fog detected mode when said rays are reflected from said fog towards said frontmost portion of said vehicle, said apparatus means including automatic braking means and automatic s~eed control means and visual signalling means and frontmost lamp control means, said automatic braking means utilized for the application of braking forces to said vehicle when said fog detecting means is in said fog detected mode, said applied braking forces being removed when said fog detecting means is in said non fog detected mode, said automatic braking means including means for automatically adjusting the amplitude of said braking forces in proportion;to the speed of travèl of said vehicle, said automatic speed control means limiting the speed of the motor of said vehicle when said fog detecting means is in said fog detected mode, said automatic speed control means ~eing inoperable when said fog detecting means ~s in said non fog detected mode, said visual signalling means visi~l~ signalling trailing vehicles locat~d beh.ind said vehicle b~ intermittently operating at least one lamp secured to a rear surface of said vehicle ~hen said fog detecting means is in said fog detected mode, said visual signalling means becoming inopera~le ~hen said fog detecting means is in said non fog detected mode, said frontmost lamp controlling means for al~:exing the lighting mode emanating forward of said vehicle from a lamp located on a front surface of said vehicle into a fog lighting mode when said fog detecting means is in said fog detected mode, said frontmost lamp control means for altering said lighting mode to a non fog lighting mode when said fog detecting means is ;.n said non fog detected .
mode.
The st,ructure and method of f.ahrication of the present invention is applica~le to a fog detect:or preferably utili~ing a small forwardly directed light source, projecting a light to~ards fog located slightly above the road~ed immediately .' preceding the forward portion of the vehicle so equipped~
photoelectric cell is directed in such a manner as to be responsive to light signals reflected from the fog ~ut unresponsive from incident lighting such as is available rom oncoming vehicles. Polarized light may be utiliæed as ~ell as conventional sound producing and detecting apparatus sensitive to the sound absorbing characteristics of the fog. The- sensor feeds a control box comprising, if desired, a rela~ which in turn, operates an automatic braking system and a light control unit when energized due to the presence of detected fog ~y the fog sensor.
.
52~2 The au-tomatlc braking system utilizes a conventional vehicular braking apparakus operated ~y a spring loaded solenoid released cylinder attached to the brak~ng hydraulic lines of the vehicle. A hydro-check unit or needle valve may ~e interposed between the pressurized side of the cylinder to control the rate of application of hydraulic forces to the master cylinder operating the braking system of the vehicle. An adjustable but preset governor is permitted to control the speed of rotation of the engine, by conventional means, when operated, so as to limit the speed of the vehicle to a preset maximum.
The control relay, when energized, causes high intensity rearmost lamps to energize utilizing a fla~her to produce intermittent illumination therefrom. A set of cantacts, operated by the control relay, when energized, may be utilized to either transfer the headlamp lightlng mode from high beam to low beam or, if desired, ~otally extinguish the conventional high-low headlamps whilst energizing a set of og lamps. ~hen fog is no longer detected, the automati.c braking system is released, the control of the governor vver the engine speed is 2a nullified, the intermittently operating fog signalling lamps are extinguished, and the headlamp or fog lamps are returned to the initial operating condition.
A specific el~bodiment of the invention is illustrated in the accompanying drawings, in ~hich:
FIGURE 1 is a side elevation vie~ of a vehicle equipped with the present invention;
FIGURE 2 is a block diagram representation of the operable components of the pre~ent invèntion.
Now referring to the figures, and more particularly to the embodiment illustrated in Fig. 1 showing vehicle 10 having a 5~
fog sensor 12 ins-talled immediately below the front bumper 14.
Rays 16 are utilized to detect t~e presence of fog 18 over roadbed 20 upon which vehicle 10 is traveling in the direction of arrow 22. Headlamps 24, rearlamps 26, a braking system, not shown, and engine 28, shown in dotted lines, are all ~odified in operation when fog sensor 12 detects fog 18.
Fig. 2 illustrates th~ fog sensor 12 providing a signal to the control box 30 when fog ~s sensed there~y. When the control ~ox 30 is activated, a signal is sent to the atuomatic braking system 32, the automatic governor 34, and the light contxol unit are simultaneously p~aced ;nto operation. The light ~ -control unit operates flasher 38 causing rear lights 40 to intermittently energize and, simultaneously, provides a signal to the head light or fog light devices of the vehicle, causing them to operate in a mode most $uitahle fox travellng in fog bound areas. When the fog sensor ceases to detect the presence of fog, tI~e control box 30 i5 made inoperative causing the automatic braking system 32, the automatic governor 34, and the ; light control unit 36 to ~ecome inoperable, e~tinguishing thereby, rearlights 40 and restoring the head and fo~ lights to a normal mode of operation and allo~ing the vehicl~ operator full manual control over the engine speed and the vehicular braking system.
One of the advantage~ of the instant invention is a vehicular control responsive to the presence of fog immediately preceding the for~ardmost portion of the vehicle.
Another advantage of the instant invention is a vehicular safety device wlth ~raking mèans automatically slowing down the vehicle upon the detection of fog.
Still another advantage o~ the instant invention is a 5i22 vehicular safe-ty device with siynalling means visi~ly signalling the detection of fog -to tra~ling vehicles.
Yet another advantage of the instant invention is a vehicular safety device with headlamps control upon the detection of fog immediately preceding th~ vehicle.
A further advantage of the instant invention is a vehicular safety device with governor control limiting the speed of the vehicle when fog bound.
Thus there is disclosed in the above description and in the drawings, an embodim~nt of the invention which fully and effectively accomplishes the objects thereof. However, it will become apparent to those skilled in the art, how to make variations and modifications to the instant invention. Therefore, this invention is to be limited, not by the specific disclosure herein~ but only by the appending claims.
