Abstract

Vehicle safety equipment has a De-Accelerometer 12, a Processor 10 and a Sequential Display Unit 14. The De-Accelerometer 12 measures the speed by which the vehicle is de-accelerating. (Braking) The Processor 10 sends the information to the Sequential Display Unit 14. The segments will light up from the centre outward with the first being a copy of the standard brake lights. From then on as the braking is increased the more segments will be lit and the display will start to flash. The more segments that light up the faster the flashing will become until all the segments are lit and the flashing is at maximum rate. This will indicate maximum braking. The system when fitted to any vehicle will display the speed by which the vehicle is de-accelerating (Braking) so that any other road users can take their appropriate action. When the anti-lock braking system (ABS) 18 is activated the maximum illumination and flash rate is immediately engaged.

VEHICLE SAFETY EQUIPMENT
This invention relates to a method of displaying the rate of Deacceleration (Braking) of a vehicle to other road users so they can take their appropriate action.
In the past the only indication to be seen that any vehicle was deaccelerating (Braking) was by the means of Brake Lights mounted either side on the rear of the vehicle. The next improvement was the introduction of centre high level stoplights in the rear window, boot or spoiler (Fig 1 l/2). These displays only showed that the vehicle was de- accelerating (Braking) and in no way demonstrated how fast this was happening. In lines of traffic, busy roads or motorways when emergency braking occurs the drivers following have no idea as to the severity of the braking vehicle. This invention will display to all other road users the severity of the braking in any vehicle fitted with this equipment.
The technical features of this invention (Fig 2 1/2) consist of a Deaccelerometer 12 that measures the rate of decrease in speed (Braking) of any vehicle from any speed. This information is then passed to the Processor 10 which, in turn sends it to the normal brake Lights 20 and the Sequential Display Units 14 or any of the suggested Sequential Display Unit shapes (Fig 3 to 6 2/2) or any other chosen display shape to suit the vehicle's design.
The basic concept and scheme of the units are shown in the following drawings.
Fig I t/2 shows the General layout of a normal control system used on many vehicles.
Fig 2 1/2 shows the General layout of the new system with the Deaccelerometer, Processor and the new style Sequential Display Unit in place.
Fig 3 2/2 shows a standard Rectangular display shape.
Fig 4 2/2 shows a Butterfly wing display shape.
Fig 2/2 shows a Bird wing display shape.
Fig 6 2/2 shows a Bull's eye display shape.
The De-accelerometer 12 will directly calculate the difference in speed and the rate of change (G Force opposite to the direction of travel) then forwarding the results to the Sequential Display Unit 14 via the Processor 10. The centre segment of the Sequential Display Unit 14 will light up with the Standard Brake Lights 20 via the Switch 16 on the brake pedal arm or inline switch. Once the brakes are actually applied and there is a change in speed, the lights in the Sequential Display Unit 14 grow in size lighting up each segment from the centre outwards to the edges. As each segment is engaged from the two lights either side of the centre they will flash. The more segments that are displayed the faster the flashing will become.
This will be triggered by the increased rate of speed change as the braking is increased.
In other words the harder the vehicle brakes the more of the display area is lit, and the faster the flashing becomes on the Sequential Display Unit 14. For vehicles fitted with Anti Locking Brakes (ABS 18) they will automatically trigger the maximum display when the ABS 18 operates. This will provide information to any other road user seeing the display of lights, the level of braking which is in progress. Light braking would only light up the centre segment and one either side would flash at a slow rate. Maximum braking would show an increase in light source output with all segments being lit and flashing at maximum rate.
Fig 3 to 6 2/2 shows a fve-band display but more or less bands could be designed although more may confuse and less may not provide enough information.
Operating by the information provided by field sensing of the brake line pressure and sent to the Processor 10 this could then be processed so as to power the Sequential Display Unit 14.
This would not show the de-acceleration in the same way as the Deaccelerometer 12. If the vehicle encountered ice or skidding the Sequential Display Unit 14 would only show the pedal pressure applied by the driver and would not give any indication as to the rate of change of the speed of the vehicle. If the vehicle was fitted with Anti-Lock Brake System (ABS 18) then only when the ABS 18 was operating would the displays coincide.
