Description

Title Deceleration Lighting System for Vehicles
Field of the invention
This invention relates to a deceleration lighting system for vehicles.
The invention
According to the invention, there is provided a vehicle deceleration lighting system comprising a deceleration lighting display arrangement on the back of the vehicle, a sensing means on board the vehicle for sensing a deceleration force applied to the vehicle, and an on-board control means such as a computer_for receiving a signal from the sensor indicative of the deceleration force being applied to the vehicle and for controlling illumination of the display arrangement in such a manner that the amount of illumination is graded proportionately to the magnitude of the deceleration force.
The arrangement may be such that the brightness of the display arrangement is graded according to the ambient lighting (i.e. day/night) but more importantly the vehicle is most desirably provided with a variably-sized display arrangement and the amount of the display arrangement which is illuminated is so graded that a larger amount of the display arrangement is illuminated in proportion to a greater deceleration force.
For example, the display arrangement may comprise a "bar" of light sources extending across substantially the full width of the vehicle. Preferably, with this arrangement, a light deceleration force produces illumination of the two outer ends of the bar, intermediate deceleration forces cause the illumination correspondingly to extend inwardly from both ends of the bar, and a heavy deceleration force causes the illumination to meet in the centre of the display, the effect being to produce illumination across the entire width of the bar. This bar preferably will be constructed of a "pixel" display of light emitting cells in a matrix form, the two halves of the bar being parts of separate circuits.
In one practical arrangement, the sensing means is constituted by a pressure transducer incorporated in the hydraulic brake fluid line to the brakes, the computer receiving a signal from the transducer indicative of the pressure being applied to the brake pedal, so that the amount of illuminat-ion is graded proportionately to the pressure developed in the brake fluid line.
In this case, the normal brake lights may constitute the light sources at the two outer ends of the bar, but this is not essential, and the lightest possible braking may cause the normal brake lights to illuminate without producing any illumination of the extended display arrangement, e.g. the bar.
A convenient transducer to employ in the hydraulic brake fluid line is a Hall effect pressure transducer. The majority of modern vehicles already incorporate an on¬ board computer providing a lesser or greater degree of engine management and/or dashboard display control, and this computer can readily be adapted to control the brake light system in the afore-described manner, so that the provision of a special computer for the purpose may be unnecessary. The computer can also be used, via a light- sensing device, to control the brightness of the entire display according to ambient lighting so that a dimming effect can take place at night to avoid dazzle. The system may also incorporate a deceleration sensing device (preferably mechanical) so that if the vehicle suffers from a strong decelerating force without the brakes being applied (i.e. an engine sieze, a sudden multiple crash situation, a heart attack at the wheel resulting in an impact) then the sensing device will send a signal to the control computer and this in turn would illuminate the whole display to warn following vehicles.
In accordance with another aspect of the invention, therefore, the pressure transducer in the hydraulic brake fluid line is dispensed with, and a deceleration sensing means is provided on-board the vehicle quantitatively to sense a deceleration force being applied to the vehicle and to send an appropriate signal to the on-board computer so that a corresponding amount of the extended display arrangement, e.g. the bar, is illuminated.
With this arrangement, the deceleration forces detected will, of course, include deceleration forces applied due to use of the brake pedal, but other deceleration forces will also be sensed. For example, a light deceleration force due to release of the accelerator pedal will be sensed, and the computer can be arranged to cause illumination of the two outer ends of the bar responsively to this light deceleration force.
A convenient deceleration sensing means may be an accelerometer of the weighted beam type with attached strain gauges, or an accelerometer of the silicon mass type with associated piezo-electric sensors.
In its second aspect, the invention is more readily applicable as a vehicle attachment for vehicles already in production or in use, as well as being built into new vehicles during manufacture. In attachment form, the system will include a dedicated computer and a bar-type lighting display adapted to be mounted across the inside of the rear window of the vehicle.
The invention provides the advantage that a following driver is made aware of the likely speed of deceleration of a vehicle in front embodying the brake lighting system in accordance with the invention, and immediately adapts his or her own braking actions accordingly. The system can also give fair warning should the vehicle in front stop or slow' ithout -braking, and a further advantage in that if the driver in front is resting their foot on the brake pedal whilst in motion (usually on automatic vehicles), so that the two outermost lights may be permanently illuminated, fair warning will still be given of braking actions as more of the display will then illuminate.
Brief description of drawings
Two arrangements of vehicle deceleration lighting system in accordance with the invention will now be described by way of example with reference to the accompanying drawings, in which:-
Figures 1 to 3 respectively show one arrangement in three differing states of operation; Figure 4 shows an alternative arrangement; and
Figures 5 and 6 show differing kinds of accelerometer for use in the alternative arrangement.
Description of embodiments
Referring to Figures 1 to 3 of the drawings, in each figure there is shown the rear of a vehicle 10 having a brake light display arrangement 12. The brakes are operated by a foot pedal 14, which via hydraulic brake fluid reservoir 16 causes application of the vehicle brakes when said pedal is depressed. The brake light display arrangement 12 is controlled by an on-board computer 18 which powers the display arrangement responsively to depression of the brake pedal.
In accordance with the invention, an extended brake light display arrangement is employed, in the form of a bar 20 of light sources which is divided into two halves electrically, but constructed as one and extending across substantially the full width of the vehicle. Bar 20 may be alternatively positioned, as indicated by reference 20A in Figures 2 and 3, and for new vehicles would obviously become part of the vehicle styling.
A Hall effect or analogous fluid pressure sensor 22 is incorporated in the brake fluid line leading to the brakes from the brake fluid reservoir 16. This sensor sends a signal to the computer 18 the magnitude of which is proportional to the fluid pressure in the line, which is in turn proportional to the amount by which the brake pedal 14 is depressed. The computer 18 responds by causing illumination of an amount of the bar 20 of brake source lights proportional to the applied brake pressure.
Figure 1 shows at 24 that only the ends of the bar (the normal brake lights) are illuminated with a light braking pressure. Figure 2 shows at 26 that the bar is illuminated for increasing amounts inwardly from its ends with increasing brake pressure, whilst Figure 3 shows at 28 that the whole bar is illuminated with heavy braking pressure.
In the alternative arrangement shown in Figure 4, the pressure transducer in the hydraulic brake fluid line is dispensed with, and a bar-type lighting arrangement 30 across the inside of the rear window of the vehicle (or in alternative positions as previously noted) is controlled by an accelerometer 32 via a computer contained in a control box 34, both -positioned at any convenient site on board the vehicle. The accelerometer 32 supplies the computer 34 with signals indicative of the magnitude of any deceleration force, including braking force, which may be applied to the vehicle, and the computer is calibrated to illuminate an amount of the lighting bar 30 proportionate to the deceleration force being applied. The computer control will be calibrated to take account of the particular application and the consequent range of *g' forces likely to be detected. Therefore a different calibration will be necessary for a Formula 1 racing car, than for a family car, and for a bus or heavy goods vehicle.
Two convenient kinds of accelerometer which may be employed for quantitatively sensing a deceleration force applied to the vehicle are shown in Figures 5 and 6, respectively. The accelerometer shown in Figure 5, wherein the reference 36 indicates the normal direction of vehicle travel, has a weighted beam 38 and associated strain gauges 40. A stop 42 may prevent generation of "negative" signals, although it is possible to use negative signals for other purposes, such as a governor for optimum fuel usage efficiency, by limiting the acceleration via an engine management computer. If required, this function could be switched in and out to give 'sport* and 'economy' modes in the manner of some automatic gearboxes.
Optionally, a stop 44 may also be provided to prevent damage due to excessive movement of the beam in the positive signal direction.
Figure 6 shows a silicon mass accelerometer. The shaped silicon mass 46 in the enclosed space 48 is associated with piezo-electric sensors 50 inset into the base of the silicon and these detect stresses caused by the movement of the mass under braking etc.
Various modifications of the above-described and illustrated systems are possible within the scope of the invention hereinbefore defined.
