Abstract
The Braking Distance Alert System consists of a warning notice or signal fitted to the rear of a vehicle and optionally an indicator on the dashboard. The rear signal warns the driver behind if he is too close for the prevailing speeds and road conditions etc, optionally accounting for types of vehicles. It can use increasingly severe signals such as flashing of hazard warning lights or giving a brake light signal etc to stop drivers ignoring it, and optionally incorporate warning signals for harsh braking, reversing, loss of control or damage to the vehicle.
Description
BRAKING and BRAKING-DISTANCE ALERT SYSTEM (BBDAS).
DESCRIPTION.
This invention relates to a device fitted to any vehicle, specially motor vehicles, that gives the following new warning signals in certain situations as outlined below:
Warning Signal 1:
To any vehicle approaching from behind when the distance gets too close for safe braking, especially taking into account the prevailing conditions, such as speeds, acceleration/deceleration, terrain road and weather conditions and the types of vehicles involved - by a visual and/or acoustic signal, such as flashing of hazard warning lights (at slower, normal or faster than normal flash rate) and/or fog lights and/or brake lights, and/or a bleep. There could be a few second lag in the cancellation of the signal after the error has been corrected. (Adjustable from 0-30 seconds). The system could also warn the driver of the front vehicle by a light on the dashboard at the same time.
Note on this signal: Normally most drivers put up warning notices to their rear windscreens such as, 'Keep your distance, Baby on Board' etc, to ensure braking distances are adhered to by following drivers. However such notices are not a deterrent any longer as they are common place and mostly ignored. Lorries can also often ignore the safe distance for their momentum and ride too close and then cannot stop in time if anything unexpected happens. A large number of accidents continue to be caused this way by driving too close for the speed and conditions. The problem is compounded by the fact that judgement of the safe distance is a personal assessment that can vary with mood and attitude at the time.
(Eg: a man hurrying to an appointment may not think it is the same as a man out driving on a sunny day.)
The above warning signal on the proposed device would eliminate these problems.
It would calculate the exact distance between it and the approaching vehicle continuously, anticipating closing distance and speed. (This type of distance measurement is commonly done already with devices such as cameras using infra red rays etc). This would take the guesswork out of the distance measurement. The device could also receive information from the car computer if fitted, or from sensors regarding speed, revs, braking, before deciding what the safe braking distance should be in the situation. As soon as this distance is anticipated to be imminently breached it would set off the warning signal. If the vehicle behind persisted and continued closing the gap, the signal could be designed to get more urgent such as fog lights coming on and the flashing becoming more rapid, a bleep coming on, or even a notice that could light up and flash saying, "Warning, you are too close."
Drivers often only come to ignore the safe distance out of overcrowded concentration and/or time, and it is expected a reminder is all that would be required for the observation of safe distance exactly.
Warning Signal 2:
On any vehicle fitted with the system, on which, if it has to brake suddenly above a set braking severity, the hazard warning lights and/or brake lights (or any other lights or sign) will flash simultaneously and automatically (slower, normal, or faster than the normal rate of flashing for hazard lights) everytime. There will be a five second lag in the automatic cancellation of the signal to show a hazardous use of brakes had occurred.
Therefore if the brake pedal is simply pumped once hard enough, the signal would come on and flash for five to eight seconds. (Lag adjustable from 0-30 seconds).
Note: This warning would be particularly useful in any situation that involves sudden braking. It would be a standard signal and work everytime mainly regardless of other factors. Currently there is nothing to indicate the severity of braking on a vehicle. All braking, from light to very sharp, is simply indicated by the brake lights. This has gradually attained the potential to be dangerous over time with developments, as modern cars fitted with ABS and high traction tyres have gradually become more and more able to stop in a shorter and shorter distances under full braking from high speeds, and even if the vehicle behind is at a safe braking distance to start with and starts braking as soon as the brake lights on the vehicle ahead come on, it may not be able to stop in time as the severity of braking is not immediately apparent, and until the following driver recognises what is happening from the closing distance, and applies his own brakes harder, the vehicles can get closer and closer and be far too close by the time full braking is applied to avoid a collision. If hazard warning lights and/or brake lights (and or any other signal etc) flashed instantly with hard braking, it would give a much better indication to the driver behind that hazardous braking was taking place ahead.
Warning Signal 3:
While the car is in reverse gear or specially in reverse motion with this system, optionally the hazard warning lights and/or any other lights such as the reversing lights, will flash (slower, normal or faster than normal flash rate) but the signal is mainly intended to warn when the car starts reverse movement, to warn motorists or pedestrians behind of the movement (as opposed to reversing lights which come on as reverse gear alone is engaged). The warning would cancel instantly the car stopped reverse motion.
Note on signal 3: Although lorries are fitted with a reversing alarm, there is nothing to indicate reversing movement accurately on a car. This signal would eliminate this problem.
Warning Signal 4:
If any vehicle approached closer than a set distance from the side when overtaking or travelling alongside, the hazard warning lights and/or fog or other lights, including side indicator lights if fitted, would flash (slower, normal or faster than normal flash) and / or a bleep would sound. There would be a lag in cancellation of the signal, adjustable from 0-30 seconds.
Warning Signal 5:
If a car or vehicle fitted with the system showed any loss of control, in any situation, for example a skid developed or swerving took place, the system will flash hazard warning lights and/or any other lights automatically and immediately. There would be a lag in the warning cancellation until the emergency had been corrected or the warning over ridden. (Lag adjustable from 0-30 seconds).
Warning Signal 6:
If the car receives any damage to the body or the engine, such a broken window, windscreen, specially while travelling, which may lead to an emergency situation, the system switches on hazard warning lights and/or any other lights immediately (slower, normal or faster than normal rate of flash). The hazard warning would stay on until the situation was corrected or signal over ridden.
Warning Signal 7:
The system would give a different standard hazard warning for a stationary vehicle which could be eg: two quick flashes followed by a pause, repeated.
Note: This signal would help to distinguish a stationary vehicle hazard from a vehicle indicating to move out from the same position. Often both the indicator lights of a vehicle on the side of the road are not visible because of other vehicles etc parked next to it, and it is not apparent to drivers passing by if the car is about to move off or displaying a hazard warning signal. This signal would eliminate this confusion.
General Note: If more than one of the above emergencies occurred the system would give priority to the most urgent. The main system could also be adapted to fit other vehicles such as bicycles, motorcycles, boats, or lorries etc.
Claims (5)
1: Any vehicle fitted with a system to warn any vehicle approaching from behind when it getb too close for the safe braking in the prevailing conditions, taking into account factors such as speeds, accelerationideceleration, terrain and road conditions, visibility and weather, the type of vehicles involved - by a visual and/or acoustic signal, such as flashing of hazard warning lights (slower, normal or faster than normal rate of flaslliny) and/or fog lights, brake lights and/or the flashing of a special sign with a message such as 'Warning, you are too close', and/or the sounding of a bleep. There could be a few second lag in the cancellation of the signal after the error had been corrected. (Adjustable form 0-30 seconds). The system could also warn the driver of the front vehicle by a light on the dashboard at the same time.
2: As in claim 1, but also if the brakes are suddenly applied over a set braking severity the hazard warning lights and/or brake lights and/or any other lights flash instantly and automatically (slower, normal or faster than normal rate of flash for hazard warning lights) everytime. There will be a five second lag in the automatic cancellation of the signal to show a hazardous use of brakes had occurred. (Lag adjustable from 0-30 seconds).
3: As in claim 1, and 2, but also incorporating a system that the hazard warning lights and/or any other lights will flash when reversing, particularly in reverse motion to warn motorists or pedestrians behind of reversing movement (slower, normal or faster than normal rate of flash). The warning would cancel instantly the car stopped reverse motion, and /or changes gear to move forward.
4: As in all or any or all claims above, but also if a vehicle approached closer than a certain set distance from the side when overtaking or moving at speed alongside, the hazard warning lights and/or any other lights, including side indicator lights if fitted, would flash ( slower, normal or faster than normal rate of flash) and/or a bleep sound. There would be a lag in cancellation of che signal, adjustable from 0-30 seconds.
5 As in any or all claims about but also if a car or vehicle fitted with the system suftis any loss of control, in any situation such as if a skid develops unexpectedly or the vehicle swerves, the system will flash hazard warning lights automatically and immediately tat a slower, normal or faster than normal rate of flash). There would be a lag in the warning cancellation until and after the emergency has been corrected or the warning over ridden.
(Adjustable 0-30 seconds).
6: If the car receives any damage to the body or the engine, such as a broken window, windscreen, specially while travelling, which might possibly lead to an emergency situation developing, the system switches on hazard warning lights and/or flashes any other lights (at a slower, normal or faster than normal rate of flash). There would be a lag in the cancellation adjustable from 0-30 seconds or until over ridden.
7: A system as in any or all claims above but a.lth a different hazard warning signal for a stationary vehicle than the standard current signal. For example two quick flashes of the hazard warning lights followed by a pause, repeated.
8: A system as in any or all claims above, but with independent powersupply so that the system and the warning lights can operate even if all the vehicle electrical supply iail 9: As in any claim above but system incorporated with the vehicle security system and 'or the car central computer system, including ABS, tracking non skid systems etc, to butter anticipate any developing problems with the car control such as emergencies and make better decisions based on the information, and able to prioritise better.
10: A system as in the above claims but one that is adapted to fit any other vehicle such as bicycles, motorcycles, boats, or lorries etc.
