`(54) Title: ELECTRICAL SYSTEM FOR ADVANCED ACTIVATION OF AUTOMOTIVE BRAKE-LIGHTS AND ITS
`CONFIGURATION
`
` (57) Abstract
`
`
`
`
`The aim of the present invention is to have the brake-lights of automotive vehicles in general activated as soon as the driver
`takes his foot off the accelerator. This set-up gives the driver of the vehicle following, a lead-time to react, not currently available.
`To implement this new configuration, the invention also introduces the use of ”intelligent” or ”live” command-pedals, that react
`instantly to the presence or absence of pressure exerted theron by the drivers foot. Furthermore, the new configuration introduces
`two additional road-safety features: parallel electric circuits to activate the vehicle’s brake-lights, and automatically activated
`brake-lights for vehicles that are temporarily stopped in traffic.

`
`lectrical system for advanced activation of
`
`automotive brake-lights and its con+iguration.
`
`The invention concerns the configuration of the electric
`
`circuit existing in all automotive vehicles, for the pur-
`
`pose of activating the brake-lights thereof.
`
`The brake—lights of automotive vehicles play an important
`
`role in overall road-safety, as their task is to alert the
`
`driver o+ the vehicle following, that the preceding ve-
`
`hicle is slowing down or coming to a halt. Ideally,
`
`the
`
`configuration of this circuit and its activating elements,
`
`should be such, that the driver of
`
`the vehicle following
`
`has sufficient time to react,
`smooth traffic flow.
`
`thereby contributing to a
`
`at the present time,
`
`the universally adopted method of ac-
`
`tivating the brake—lights of automotive vehicles in gener-
`
`al, is to use a "dumb“ brake-pedal and to incorporate some-
`
`where along the hydraulic circuit that activates the bra~
`
`kes, a pressure-sensitive switch. This contact-switch will
`
`cause the brake-lights to glow, as soon as, but not before,
`
`pressure has been created in the hydraulic circuit, due to
`
`the driver's activation of the brake—pedal. The result of
`
`employing this classical configuration is, that the vehi—
`
`cle's brake—lights will go on simultaneously with the
`
`actual functioning of the vehicle's brakes.
`
`Consequently,
`
`the driver of the vehicle immediately fol-

`
`lowing, is only made aware of the deceleration of the pre—
`
`ceding vehicle, once braking is already in progress. This
`
`éorces him to apply a greater pressure to his brakes than
`
`the driver of the preceding vehicle and,
`
`in many instances,
`
`m
`
`the second vehicle is actually unable to "catch-up" with
`
`the deceleration of the preceding vehicle- This, of course,
`
`results in the all too common rear-end collision, not only
`
`of the single variety, but also of the chain or multiple
`
`variety,
`
`in such situations where road and climatic con—
`
`lfi
`
`ditions are adverse and/or a higher speed is permitted on
`
`the road or highway.
`
`The last 35 years have witnessed drastic improvements in
`
`automotive braking technology, such as the power-assisted
`
`brake,
`
`the disk-brake and the anti-lock Braking System,
`
`15
`
`all of which have resulted in considerably reduced braking
`
`distances- Meanwhile,
`
`the electrical system activating the
`
`brake-lights, has remained essentially static, paralleled
`
`only by an unchanged human reaction-time.
`
`M
`
`0
`
`Therefore, it is the aim of this invention to overcome the
`
`human handicap,
`
`through introduction of a new electrical
`
`configuration, that will give drivers following another
`
`vehicle, up to two seconds of additional reaction-time.
`
`Firstly, the invention as claimed,
`
`introduces the concept
`
`25
`
`of activating the vehicle's brake-lights, as soon as the
`
`driver takes his foot of; the accelerator—pedal. Not only

`
`is the release o+ the accelerator-pedal
`
`the first motion
`
`towards stepping on the brake-pedal, but
`
`in actual iact,
`
`a release of
`
`the accelerator—pedal causes by itself a de-
`
`celeration of the vehicle, of which the driver of the ve-
`
`L."
`
`hicle that follows, should be made aware of instantly.
`
`Secondly,
`
`the invention as claimed,
`
`introduces the concept
`
`of activating the vehicle’s brake-lights through "live” or
`
`"intelligent" command-pedals, which either have pressure—
`
`sensitive contact—switches built into said pedals, or have
`
`such pressure—sensitive switches or electronic sensors
`
`attached to said command-pedals. These pedals do provide
`
`an instant response to the absence or presence of the
`
`pressure exerted thereon by the driver‘s foot.
`

`
`Ana.LXJ
`
`To accomplish the aims of the present invention, we must
`
`distinguish between automotive vehicles equipped with
`
`automatic transmissions and those with manual gear-boxes.
`
`Because the driver of a vehicle equipped with an automatic
`
`transmission has his right foot either on the accelerator—
`
`pedal or on the brake—pedal, such a vehicle would, ”a
`
`priori", require only its accelerator—pedal to be of the
`
`"intelligent" variety, as it is the fundamental aim of the
`
`present
`
`invention,
`
`to have the brake—lights activated, as
`
`soon as the driver's foot comes ofi the accelerator—pedal.
`
`Notwithstanding, a higher degree of reliability and hence,
`
`overall safety is achieved, by using concurrently also an

`
`PCP/EP92/00362
`
`”intelligent" brake—pedal, which activates the vehicle's
`
`LI
`
`brake-lights in parallel with the accelerator-pedal.
`
`In contrast to this,
`
`the driver of a vehicle equipped with
`
`Lil
`
`a manual gear-box, may take his right foot off the accel-
`
`erator—pedal, not only in order to initiate the braking
`
`process, but also in order to change gears. Consequently,
`
`to prevent the emission of a false or spurious braking
`
`signal, the manual gear-box vehicle will also be equipped
`
`v’
`17 with “intelligent" clutch—pedal and "intelligent" brake—
`
`pedal".
`
`In this configuration,
`
`the driver takes his foot
`
`of? the accelerator, and this would normally cause the bra—
`
`te—lights to turn on, as intended. However, if his aim is
`
`to change gears, he has already placed his left foot on
`
`15
`
`the clutch-pedal, which in this configuration incorporates
`
`a "defeat-switch", that overrides and cancels the signal
`
`from the accelerator. Hence, during gear—changes the brake—
`
`lights are not activated at all, as usual. On the other
`
`hand, if the driver has to decelerateg his right foot
`
`20
`
`leaves the accelerator—pedal, which instantly activates
`
`the brake-lights. His right Foot now depresses the "intel—
`
`ligent" brake-pedal, which then also activates the brake-
`
`lights in parallel with the accelerator-pedal.
`
`fit this
`
`point,
`
`the driver may realise that he has to come to a
`
`h]Ul
`
`halt, and therefore he also depresses the clutch-pedal.
`
`This overrides and defeats the signal emanating from the
`
`accelerator-pedal and, were it not for the parallel feed

`
`from the brake—pedal,
`
`the brake-lights would go out.
`
`However, as these lights are also activated by the brake—
`
`5.
`
`~73
`
`pedal, which is being depressed,
`
`the vehicle's brake—
`
`lights will
`
`remain on, as required by universal traffic
`
`U!
`
`legislation.
`
`.-. o
`
`NI‘D
`
`in addition,
`
`the new configuration has the advantage,
`
`that any automotive vehicle which is temporarily stopped
`
`in trafiic or on the side of the road, but not parked,
`
`will automatically have its brake—lights on, because the
`
`driver has taken his foot off the accelerator. This impro-
`
`ves other driver‘: awareness and hence road-safety.
`
`There are basically three ways of
`
`implementing the
`
`present invention, which vary in their degree of sophis-
`
`tication and consequent reliability.
`
`The most elementary set-up would consist in simply using
`
`conventional electric switches attached to the command-
`
`pedals of the vehicle. However, due to wear and tear,
`
`dust and humidity,
`
`this technical solution would be of
`
`questionable reliability and require frequent checks and
`
`maintenance.
`
`In addition, due to the mechanical nature
`
`of conventional switches, a degree of "travel" is invol—
`
`ved which reduces the instant response aimed for by this
`invention.
`
`{‘4
`
`a second and more reliable design does involve the use of
`
`"live“ or "intelligent" command—pedals, which incorporate
`
`a pressure-sensitive electric switch built into the pedal

`
`itself. These pedals will provide the instant response
`
`required, as soon as the driver steps on or off the com—
`

`
`mand—pedel
`
`in question.
`
`In addition, such pedals being
`
`g
`
`U1
`
`p... o
`
`entirely sealed, are impervious to dust and humidity,
`
`thereby requiring no maintenance, apart from the flexible
`
`wiring leading to the vehicle’s brake—lights.
`
`‘
`
`Finally, the "luxury" configuration employs electronic
`
`sensors, which relay the absence or the presence of pres-
`
`sure exerted by the driver's foot on the command-pedals,
`
`to the on—board-computer, which then transmits the re—
`
`quired signal to the brake-lights. vaiously, this solu—
`
`tion pre—supposes the existence of such on-board-computer
`
`and therefore, is reserved for vehicles so equipped.
