Abstract
An early warning system for a vehicle 4 comprises a first sensor 8, for detecting the illumination of rear brake lights 5 of a second vehicle 6, a second sensor 10 for detecting the distance X between the vehicles, a speed sensor (Fig 2, 11) and a control means (Fig 2, 13). The control means illuminates the brake lights 12 of vehicle 4 to warn following traffic 2 when it is determined that the speed of the vehicle 4 is above a threshold speed and the distance is below a threshold distance when the brake lights 5 on the preceding vehicle are activated. The system may have an additional sensor (Fig 2, 14) for detecting precipitation causing the control means to adjust the threshold values. The system may also have an audible or visual alarm 16 in the drivers compartment which is activated when the control means activates the brake lights of vehicle 4. The control means may also record the distance between the vehicles and activate the brake lights if the rate of distance decrease is greater that a threshold value.
Description
I
EARLY WARNING SYSTEM
The present invention relates to an early warning system for a vehicle and particularly but not exclusively to an early warning system for alerting the driver of a following vehicle that traffic ahead is slowing down.
BACKGROUND
Many vehicle traffic accidents occur when a vehicle following another vehicle collides with the vehicle in front. This can be caused, at least in part, by vehicles being driven too close to one another. In fast moving traffic, when, in particular, a group of cars are of similar size, a driver is able to see and can react to the illumination of brake lights several cars ahead and not just to the brake lights of the car immediately in front. The introduction, in some cars, of a third brake light positioned above the level of standard brake lights, has facilitated this practice.
The increasing volume of large vehicles, including four wheel drive vehicles, multi person vehicles (MPVs) and commercial goods vehicles, means that it is often impossible to see further than the vehicle immediately ahead. This has the result that the brake lights of vehicles in front of a large vehicle are obscured to a driver following the large vehicle. The driver of a following vehicle is therefore forced to rely upon the driving skills and reflexes of the driver of the large vehicle in front in applying his brakes early, when traffic is slowing down. If a large vehicle brakes suddenly, the risk of a driver of a smaller vehicle following behind colliding with the rear of the large vehicle is high, because the driver is only able to see and react to the illumination of the brake lights of the large vehicle. In other words, there is no early indication that traffic ahead is slowing down.
It is an object of the present invention to provide an early warning system for a vehicle, which is adapted to warn the driver of a vehicle following behind, that traffic ahead of the vehicle is slowing down.
SUMMARY OF INVENTION
According to the present invention, there is provided an early warning system for a vehicle comprising a first sensor for detecting the illumination of rear brake lights of a second vehicle, means for recording the speed of the vehicle, a second sensor for detecting the distance between the vehicle and the second vehicle, and control means, the control means being adapted to illuminate rear brake lights of the vehicle when the speed of the vehicle is above a threshold speed, the distance between the vehicle and the second vehicle is below a threshold distance and the sensor detects illumination of the rear brake lights of the second vehicle.
It is an advantage of the invention that a driver following a large vehicle is given early warning of a potentially dangerous situation caused by traffic slowing down, by illumination of the brake lights of the large vehicle.
The threshold values of speed and distance for the system may be set by the control means.
The first sensor of the early warning system may be a photosensor. The first sensor may be adapted to detect the intensity of the illuminated rear brake lights of the second vehicle. It is an advantage of the invention that the first sensor thus detects the illumination of rear brake lights and not the sudden illumination of rear night lights.
The system may further comprise a third sensor to detect the presence of precipitation, for example rain or snow, and the control means may be adapted to adjust the threshold distance and threshold speed according to an output from the third sensor.
Preferably, the control means is adapted to increase the threshold distance when precipitation is detected and to decrease the threshold speed when precipitation is detected.
An alarm may be disposed in the cab of the vehicle, which may be a visual alarm and/or an audible alarm. Preferably, the control means is adapted to activate the alarm when it illuminates the brake lights of the vehicle.
In one embodiment, the control means is adapted to record the distance between the vehicle and the second vehicle over a predetermined period of time. The control means may be adapted to illuminate the rear brake lights of the vehicle if the distance between the vehicle and the second vehicle decreases at a rate greater than a threshold value.
According to another aspect of the present invention, there is provided a method of warning traffic following a vehicle, the method comprising: a) sensing the speed of the vehicle, b) sensing the distance between the vehicle and a second vehicle c) sensing the illumination of the rear brake lights of the second vehicle, d) illuminating rear brake lights of the vehicle when the speed of the vehicle is above a threshold speed, the distance between the vehicle and the second vehicle is below a threshold distance and the rear brake lights of the second vehicle are illuminated.
The method may further comprise sensing the presence of precipitation and adjusting the threshold distance and threshold speed according to the presence or absence of precipitation.
Step d of the method may further comprise activating an alarm to warn the driver of the vehicle when the speed of the vehicle is above a threshold speed, the distance between the vehicle and the second vehicle is below a threshold distance and the rear brake lights of the second vehicle are illuminated. The alarm may be a visual alarm and/or an audible alarm.
The method may further comprise recording the distance between the vehicle and the second vehicle over a predetermined time and illuminating the rear brake lights of the vehicle if the distance between the vehicle and the second vehicle decreases at a rate greater than a threshold value.
According to another aspect of the present invention, there is provided an early warning system for a vehicle comprising a means for recording the speed of the vehicle, a sensor for detecting the distance between the vehicle and a second vehicle, and a control means, the control means being adapted to illuminate rear brake lights of the vehicle when the speed of the vehicle is above a threshold speed and the distance between the vehicle and the second vehicle decreases at a rate greater than a threshold value.
An alarm, as described in connection with the first aspect of the invention, may also be activated by the control means when the speed of the vehicle is above a threshold speed and the distance between the vehicle and the second vehicle decreases at a rate greater than a threshold value.
It is an advantage of this aspect of the invention that if, for example a driver falls asleep at the wheel, and he rapidly approaches another vehicle, he will be warned and a vehicle behind is warned.
BRIEF DESCRIPTION OF THE DRAWINGS
For a better understanding of the present invention, and to show more clearly how it may be carried into effect, reference will now be made, by way of example, to the accompanying drawings, in which:- Figure 1 is a schematic diagram illustrating a situation in which the invention may operate to provide an early warning; Figure 2 is a schematic diagram illustrating the apparatus of the invention; and Figure 3 is a flow chart illustrating the method of the invention.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Referring to Figure 1, an early warning system for a vehicle 4, travelling in a direction indicated by the arrow A, provides a warning for a driver of a vehicle 2, that is following the vehicle 4. The vehicle 4, which is typically a large vehicle such as a heavy goods vehicle as shown in Figure 1, obscures the view of the driver of the vehicle 2 of traffic ahead, represented by vehicle 6. Thus the driver of the vehicle 2 cannot see when brake lights 5 of the vehicle 6 are illuminated.
Referring also to Figure 2, the warning system comprises a photosensor 8, mounted on the front of the vehicle 4, a distance sensor 10, mounted adjacent the photosensor 8, a speed sensor 11 for measuring the speed of the vehicle 4, a moisture sensor 14 to detect the presence of precipitation, an alarm 16, situated within the cab of the vehicle 4 and a control means 13.
The photosensor 8 includes an intensify sensor that can differentiate between the illumination of the brake lights 5 of the vehicle 6 and the illumination of rear night lights of the vehicle 6. The distance sensor 10 measures the distance x, indicated in Figure 1, between the vehicle 4 and the vehicle 6 in front of the vehicle 4. The alarm 16 is a visual alarm such as, for example, an LED or other light source, and/or an audible alarm such as a buzzer. The control means 13 receives information or data signals from the photosensor 8, distance sensor 10, speed sensor 11 and moisture sensor 14 and emits a signal to illuminate brake lights 12 of the vehicle 4 and sound the alarm 16, dependent on the data received.
The control means 13 includes a controller 20, first and second comparators 22 and 24 and a clock 26. Prior to operation, threshold values are manually input into the controller 20. The threshold values include values for speed of the vehicle 4, the distance x between the vehicle 4 and the vehicle 6 in front of the vehicle 4, and the rate of change of the distance x over time 5xIöt. The threshold values of speed and distance are set respectively at a speed over which the warning system is desired to be operational and a distance below which the warning system is desired to be operational. The threshold value of öxIOt is set to a value that indicates harsh braking by the vehicle 6, i.e. a large negative value of x/ t.
In a first mode of operation, the controller 20 receives a continuous data stream from the moisture sensor 14 and adjusts the stored threshold values of speed, distance x and ox/Of according to the presence or absence of precipitation. For example, the threshold speed is reduced in wet weather and the threshold distance x is increased in wet weather. The controller 20 outputs the adjusted threshold values of speed and distance x to the first comparator 22, and outputs the adjusted threshold values of speed and Ox/Ot to the second comparator 24.
The first comparator 22 receives continuous data streams from the controller 20, the photoserisor 8, the speed sensor 11 and the distance sensor 10. The first comparator 22 processes the data received according to the flow chart at Figure 3. The first comparator 22 compares the current speed of the vehicle 4, received from the speed sensor 11, to the threshold speed value, received from the controller 20. If the speed of the vehicle 4 is less than the threshold speed, the first comparator 22 returns to the beginning of the sequence and continues to compare the current speed of the vehicle 4 to the threshold speed. If the speed of the vehicle 4 is greater than the threshold speed, the first comparator 22 compares the distance x, received from the distance sensor 10, with the threshold value of the distance x, received from the controller 20. If the distance x is greater the threshold distance, the first comparator 22 returns to the beginning of the sequence. If the distance x is below the threshold distance, the first comparator 22 compares the signal received from the photosensor 8 to a datum value.
If the signal from the photosensor 8 indicates that the brake lights 5 of the vehicle 6 are off, the first comparator 22 returns to the beginning of the sequence. If the signal from the photosensor 8 indicates that the brake lights 5 of the vehicle 6 are on, the first comparator 22 sends a signal 18 to activate a warning. The first comparator 22 continues to send the signal 18 until the signal from the photosensor 8 indicates that the brake lights 5 of the vehicle 6 have been turned off, at which point the first comparator 22 ceases to send the signal 18 and returns to the beginning of the sequence.
The sending of signal 18 results in two separate operations, indicated by the division of the flow chart in Figure 3. A first signal is sent to illuminate the brake lights 12 of the vehicle 4 and this signal is maintained until the comparator 22 ceases to send the signal 18. A second signal is sent to activate the alarm, however, this signal is only sent if the brakes of the vehicle 4 are not already applied. If the driver is already aware of a need to slow the vehicle 4 down and has therefore already applied the brakes of the vehicle 4, activation of the alarm is not necessary and the signal to activate the alarm is not sent. If the signal to activate the alarm is sent, this signal is maintained until either the comparator 22 ceases to send the signal 18 or the driver applies the brakes of the vehicle.
In a second mode of operation, the second comparator 24 receives continuous data streams from the controller 20, the speed sensor 11, the distance sensor 10 and the clock 26. The second comparator 24 calculates continuous values of x/6t from the data received from the distance sensor 10 and the clock 26. The second comparator 24 compares the current speed of the vehicle 4, received from the speed sensor 11, to the threshold speed value, received from the controller 20, in the same manner as the first comparator 22. If the speed of the vehicle 4 is less than the threshold speed, the second comparator 24 returns to the beginning of the sequence and continues to compare the current speed of the vehicle 4 to the threshold speed. If the speed of the vehicle 4 is greater than the threshold speed, the second comparator 24 compares the current value of xTht with the threshold value of öx/ t. If the current value of öx/öt is greater than the threshold value, the second comparator 24 returns to the beginning of the sequence. If the current value of x/ t is lower than the threshold value, ie the gap x between the vehicles is rapidly closing, then the second comparator 24 sends a signal 19 to activate a warning. The second comparator 24 continues to send the signal 19 until the signal from the distance sensor 10 indicates that the value of öx/t has risen above the threshold value, at which point the second comparator 24 ceases sending the signal 19 and returns to the beginning of the sequence. The operation of the system from this point onwards (sending of signals to the brake lights and alarm) is identical to that as described above with reference to the first mode of operation.
The output signals 18 and 19 from the first and second comparators 22 and 24 are combined through an inclusive OR gate 28 to form an output signal 30 from the control means 13. Thus the control means 13 sends the output signal 30 if either of the aforementioned conditions for illumination is met, enabling the system to operate in the first and second modes simultaneously.
The output signal 30 from the control means 13 is divided into a signal 30a to the brake lights 12 and a signal 30b to the alarm 16. An output signal 34 from a brake pedal of the vehicle 4 is divided into a signal 34a to the brake lights 12 and a signal 34b to the alarm 16. The signal 30a from the control means 13 to the brake lights 12 is combined with the signal 34a from the brake pedal to the brake lights 12 through an inclusive OR gate 32. Thus the brake lights 12 are illuminated if either the brake pedal is applied or a condition for illumination by the warning system is met. The signal 30b from the control means 13 to the alarm 16 is combined with the inversion 34c of the signal 34b from the brake pedal to the alarm 16 though an AND gate 36. Thus the alarm 16 is activated only if a condition for activation by the warning system is met and the brakes have not already been applied by the driver of the vehicle 4.
In the first mode of operation, the warning system illuminates the rear brake lights 12 of the vehicle 4 if the vehicle 4 is travelling over the threshold speed, e.g. 40kph, the distance between the vehicle 4 and the vehicle 6 in front is below the threshold distance, e.g. 50m, and the rear brake lights 5 of the vehicle 6 are illuminated. The warning system sounds the alarm 16 if the condition for illumination of the brake lights is met and the brakes have not already been applied.
In the second mode of operation, the warning system illuminates the rear brake lights 12 of the vehicle 4 if the vehicle is travelling over a threshold speed, e.g. 5Okph, and the distance x between the vehicle 6 and the vehicle 4 decreases at a rate greater than a threshold rate, due to strong braking of the vehicle 6. The warning system sounds the alarm 16 if the condition for illumination of the brake lights is met and the brakes have not already been applied.
The system operates both the first and second modes simultaneously.
