Abstract

A brake light system comprises a pressure sensitive or movement sensitive sensor 1 activated by the action of the brake pedal. Activation of the sensor 1 results in the triggering of the illumination of one or more segments of the brake-light array 2, the number of segments illuminated being directly proportional to the pressure applied to the brake pedal of the speed at which the brake pedal is depressed. Also disclosed is a brake light system in which each brake light unit consists of more than one segment, each segment being capable of independent illumination.

Description

DESCRIPTION
SAFETY BRAKING SYSTEM
This invention relates to a brake-light system for motor vehicles.
One of the crucial factors impacting on the severity of road traffic accidents, particularly on motorways, is the speed of following drivers' reactions in taking preventative action. With current prevalent braking technology, it is impossible for an approaching driver to accurately assess whether or not he or she is in a serious braking situation. The approaching driver has to rely on rapid assessment of relative speed and distance, and the speed at which the situation is changing, in order to judge an appropriate reaction. These assessments take time (albeit splitseconds), during which the situation can escalate rapidly. At motorway speeds an error of judgement or fractional delay in response can prove ultimately fatal.
An object of this invention is to give a clear indication to a following driver of the seriousness of the braking situation ahead, by displaying an external indication of how hard and how fast the leading driver is pressing the footbrake.
Accordingly, this invention provides a system whereby the action of the footbrake-pedal directly controls graded illumination of the external rear brake-light array.
A preferred embodiment of the invention will now be described with reference to the accompanying drawing in which: Figure 1 (Fig. 1) shows an example of a connection system between footbrake-pedal and a rear brake-light array; Figure 2 (Fig.2) shows an example of how the rear brake light arrays might appear when affixed to the rear of a vehicle.
The attached drawing indicates a system for linking a pressure- and/or movement-sensitive brake-pedal sensor (Figure 1, 1) to a segmented array of rear brake-lights (Figure 1, 2), illuminated by means of electric bulb or light- emitting diode (LED) or other form of illumination.
The sensor is incorporated into, or affixed to, the footbrake-pedal, and connected to the rear brake-light arrays. The brake light arrays are segmented, with each segment being capable of independent illumination.
The number of segments lit by the action of braking is dependent on the speed and/or pressure with which the brake-pedal is depressed, as recorded and processed by the sensor.
A light braking situation (for example, a driver riding' the brake pedal) would light only one segment, whereas a heavy braking scenario, for example of the degree of severity that would perhaps trigger the vehicle's automatic braking system (ABS), would light all segments.
Figure 2 gives an example of how the segmented brake-light array might appear when fitted to the rear of a vehicle. The example shows brake light arrays consisting of five independent segments, but this could be adjusted to allow for factors such as space limitation and aesthetic design.

Claims (4)

  1. A rear brake-light system for motor vehicles, including a pressure- and/or movement-sensitive sensor affixed to a motor vehicle brake-pedal, and a system of electrical wiring or similar connected to a segmented brake-light array to be affixed or incorporated into the rear of a motor vehicle.
  2. 2. A brake-light wiring system as claimed in Claim 1 where the pressure applied to the brake pedal or the speed with which the brake-pedal travels causes one or more segments of the rear brake-light array to become illuminated, the number of segments illuminated being directly related to, and controlled by, the pressure applied to the brake-pedal by the driver, and/or the speed with which the brake pedal travels.
  3. 3. A brake-light system as claimed in Claim 1 and 2 where the rear brakelight array consists of segments illuminated by electric bulb or lightemitting diode (LED) or any other form of illumination.
  4. 4. A brake-light illumination system whereby one discrete rear brakelight unit consists of more than one segment, each segment being capable of being illuminated independently of each other segment.
