Abstract

A vehicle 1 has an inbuilt traffic control system comprising a main computer 4 which is connected for control purposes to a laser or radio device including an emitter and means for detecting a laser ray 6 or radio waves reflected from a vehicle 2 being followed. Control may be provided by a switch mounted on a steering wheel 3 and a speedometer 3, and the main computer 4 is also connected for control purposes to a carburetor 10, brake gear 9 and a speaker. The laser equipment located in the front part of the vehicle 5 measures the distance between the vehicles due to the laser ray 6. When the distance between vehicles 1,2 is reducing or increasing the computer sends a signal for braking or acceleration to the mechanisms installed in the brake gear 9 or in the carburettor 10. Automatic control is thus provided in situations such as traffic jams which can lead to driver tiredness. The system does not provide such automatic control under certain conditions such as when the speed of the host vehicle exceeds a defined threshold such as 70 km per hour or when the driver operates a pedal 12.

Description

* 1 2455584 Traffic control system This invention relates to a vehicle traffic control.
When vehicle drivers get into traffic jams, it always entails some inconveniences such as continuous use of accelerator and brake in order to move ahead in traffic jam. This makes the driver easily tired, what leads to correspondent consequences.
To overcome this problem the present invention proposes a traffic control system, the vehicles will move ahead in the traffic jam automatically due to changed distance between your and front vehicles, what is measured by laser equipment. Any changes in the distance are registered and processed by the computer, which sends the signal to the acceleration or braking. -It guarantees that the distance between your and front vehicle in traffic control mode will be secure, as it will be controlled by the reliable software.
While moving ahead in the traffic jam traffic control will let the drivers not to use the accelerator and brake excessively, as your vehicle will automatically follow the front vehicle due to the changed distance between them.
Traffic control is preferably installed in the automatic vehicles. However, installation is possible in all the vehicles.
Preferably computer of traffic control system has 6 mechanisms. It is a laser distance measuring equipment installed in the front part of a vehicle. Mechanism in the carburettor, mechanism in the brake gear, loud speaker, automatic inbuilt switch on/off in the steering wheel, and a mechanism installed in the speedometer for speed control.
Preferably the distance in traffic control mode may be changed due to the programmed computer.
Preferably traffic control system has secure peculiarities: if the computer registers a sudden change in the distance, it switches off traffic control in order to avoid some unpleasant situation. For example:! )if the laser ray has lost the front vehicle, traffic control software will prevent quick speed and will switch off traffic control. This action will be accompanied by an alarm signal 2)if any vehicle should try to get between your vehicle and the front vehicle, traffic control software will prevent abrupt braking and will switch off traffic control mode.
Traffic control system has speed limitation in order to prevent switching on of traffic control mode while high speed, because it is meant for moving ahead in traffic jams with low speed and can be dangerous if used on high speed. Maximal speed is lOkm/h.Traffic control is switched off automatically if the speed higher than this. You will hear an informative signal.
Preferably traffic control system has distance limitations what meant for the case of abrupt braking of the front vehicle or its breakage. In this case you will have one meter distance for secure U-turn.
Preferably traffic control is easily switched off by a simple pressing to the accelerator or brake pedal, or pressing a special switching on/of button inbuilt into the steering wheel.
Preferably traffic control mode can be switched on only when the front vehicle is at the distance of 2.5 to 2.6 meters. This helps to avoid abrupt acceleration or abrupt braking when switching on the traffic control mode.
This invention will now be described solely by way of example and with reference to the accompanying drawings in which: Figure 1 shows two vehicles in the traffic jam, describes location of traffic control system and the process of work.
Figure 2 shows the laser ray of measuring equipment which measuring the distance between two vehicles. The laser ray is divided into a few parts, in which traffic control system works.
Figure 3 shows a separate laser ray divided into parts, dcscribing in meters and percentage the principles of work of traffic control system.
Figure 4 shows a separate laser ray divided into 4 parts and describes functions of traffic control system in the various parts.
Figure 5 shows two vehicles in a traffic jam. In once of the vehicles there is installed traffic control system with alternative measuring device.
Figure 1 shows two vehicles 1,2. The vehicle on the left 1 has traffic control mode switched on from the mechanism inbuilt into the steering wheel 3. The laser equipment located in the front part of the vehicle 5 measures the distance between the vehicles due to the laser ray 6.The distance in this case is one meter 7 and it is the shortest distance possible in the traffic control mode. The laser equipment sends information about the distance by wise 8 to the computer 4, which processes this information and sends a signal to the mechanism installed in the brake gear 9 to provide 100% of braking. In case the distance would be 2.6 meters, computer of traffic control would send a signal to the mechanism installed in the carburettor 10 to provide acceleration. In case the speed in the traffic control mode is higher than 70 kin/h, the sensor in the speedometer 11 will send information to the computer 4 which will switch off the traffic control mode. The traffic control mode can be switched off by pressing the accelerator pedal and the brake pedal 12, or by pressing the button on the steering wheel 3.The accelerator and brake pedals 12 switch off traffic control mode due to the mechanisms installed in the brake gear 9 and in the carburettor. In case one the pedals is slightly pressed, the mechanisms will register this and will send a signal to the computer 4, which will switch off the traffic control mode.
S
Figure 2 shows the laser ray 1 divided into the parts in which traffic control mode works. This distance between the vehicles is four meters, where the dispatch point of the laser ray is A 2, and the adherent point with the front vehicle is B 3.This distance is maximal for traffic control mode. At this distance traffic control sends a signal to the mechanism installed in the carburettor for complete acceleration, which is 80% in the traffic control mode, because traffic control works at low speed and does not need 100% of acceleration. When the distance between point A and B 2,3 reduced up to 2.6 meters 4,the computer off traffic control sends a signal for braking to the mechanism installed in the brake gear. When the distance between pints A and B is reduced up to 2.5 meter 5 the computer off traffic control sends a signal for braking. And when the distance between points A and B is reduced up to one meter 6, the computer sends a signal for 100% braking.
Figure 3 shows the laser ray 1 divided into the parts, where the dispatch point of ray is A 2, and the adherent point with the front vehicle is B 3.Total length of the ray from A to B is four meters. The ray is divided into four parts.ln the upper part the ray shows meters, in the lower part it shows percentage 5.Work of the mechanisms of acceleration and braking traffic control mode was also taken in percentage from zero to one hundred. For example, if the point B will be at the distance of one meter 6 from the point A, the computer 6 of traffic control shall send a signal for 100% braking to the mechanism installed in the brake gear. The same will happen at the distance of one meter 14, from the point A to the point of one meter 6. However, if the point B will start to move off from the point of one meter 6, the next 1.5 meters 7. until the point of 2.5 meters 8 braking will decrease from 100% of pressing to 0% of pressing, i.e. if we divide 1.5meters by 100% of pressing, then every 1.5 centimetres of moving off the braking will decrease by 1%.The next ten centimetres 9 of moving off from the point of 2.5 meters 8 to the point of 2.6 meters 1 0,the mechanisms of braking and acceleration of traffic control will not be active. It is envisaged to provide a pause for the acceleration and brake mechanisms for successful switching of the mechanisms from one phase to another one (braking -acceleration, acceleration -braking). The next 1.4 meters 11 of moving off from the point of 2.6 meters 10 to the point of four meters 12 the acceleration will increase from 0% of pressing to 80% of pressing, i.e. if we divide 1.4 meters by 80% of pressing, then every 1.75 meters of moving off the acceleration will increase by 1%. However, if the point B will start to approach the point A, traffic control mode will keep on working in the same mode, but only in the opposite direction. S.

Figure 4 shows a laser ray I of traffic control system where the dispatch point is A 2, and the adherent point with the front vehicle is B 3.Total length of the ray from A to B is four meters. The first and second parts 4,5 from the point A are of the total length 2.5 meters and these are braking parts in the traffic control mode. The third part 6 of the length of 10 centimetres is inactive and serves as pause for successfiul switch oh the acceleration and brake mechanisms from one phase to another one (braking -acceleration, acceleration -braking).The fourth part 7 of the total length of 1.4 meters is the acceleration part in the traffic control system.
Figure 5 shows two vehicles 1,2. In the left vehicle 1 there is installed traffic control system with alternative radio measurer of the distance 3.This traffic control system functions according to the same principle as traffic control system with laser device described above. The difference is that the radio measuring device measures the distance between the vehicles due to the radio waves 4. * 1 2455584 Traffic control system This invention relates to a vehicle traffic control.

Figure 4 shows a separate laser ray divided into 4 parts and describes functions of traffic control system in the various parts.
Figure 5 shows two vehicles in a traffic jam. In once of the vehicles there is installed traffic control system with alternative measuring device.
Figure 1 shows two vehicles 1,2. The vehicle on the left 1 has traffic control mode switched on from the mechanism inbuilt into the steering wheel 3. The laser equipment located in the front part of the vehicle 5 measures the distance between the vehicles due to the laser ray 6.The distance in this case is one meter 7 and it is the shortest distance possible in the traffic control mode. The laser equipment sends information about the distance by wise 8 to the computer 4, which processes this information and sends a signal to the mechanism installed in the brake gear 9 to provide 100% of braking. In case the distance would be 2.6 meters, computer of traffic control would send a signal to the mechanism installed in the carburettor 10 to provide acceleration. In case the speed in the traffic control mode is higher than 70 kin/h, the sensor in the speedometer 11 will send information to the computer 4 which will switch off the traffic control mode. The traffic control mode can be switched off by pressing the accelerator pedal and the brake pedal 12, or by pressing the button on the steering wheel 3.The accelerator and brake pedals 12 switch off traffic control mode due to the mechanisms installed in the brake gear 9 and in the carburettor. In case one the pedals is slightly pressed, the mechanisms will register this and will send a signal to the computer 4, which will switch off the traffic control mode.

Figure 2 shows the laser ray 1 divided into the parts in which traffic control mode works. This distance between the vehicles is four meters, where the dispatch point of the laser ray is A 2, and the adherent point with the front vehicle is B 3.This distance is maximal for traffic control mode. At this distance traffic control sends a signal to the mechanism installed in the carburettor for complete acceleration, which is 80% in the traffic control mode, because traffic control works at low speed and does not need 100% of acceleration. When the distance between point A and B 2,3 reduced up to 2.6 meters 4,the computer off traffic control sends a signal for braking to the mechanism installed in the brake gear. When the distance between pints A and B is reduced up to 2.5 meter 5 the computer off traffic control sends a signal for braking. And when the distance between points A and B is reduced up to one meter 6, the computer sends a signal for 100% braking.
Figure 3 shows the laser ray 1 divided into the parts, where the dispatch point of ray is A 2, and the adherent point with the front vehicle is B 3.Total length of the ray from A to B is four meters. The ray is divided into four parts.ln the upper part the ray shows meters, in the lower part it shows percentage 5.Work of the mechanisms of acceleration and braking traffic control mode was also taken in percentage from zero to one hundred. For example, if the point B will be at the distance of one meter 6 from the point A, the computer 6 of traffic control shall send a signal for 100% braking to the mechanism installed in the brake gear. The same will happen at the distance of one meter 14, from the point A to the point of one meter 6. However, if the point B will start to move off from the point of one meter 6, the next 1.5 meters 7. until the point of 2.5 meters 8 braking will decrease from 100% of pressing to 0% of pressing, i.e. if we divide 1.5meters by 100% of pressing, then every 1.5 centimetres of moving off the braking will decrease by 1%.The next ten centimetres 9 of moving off from the point of 2.5 meters 8 to the point of 2.6 meters 1 0,the mechanisms of braking and acceleration of traffic control will not be active. It is envisaged to provide a pause for the acceleration and brake mechanisms for successful switching of the mechanisms from one phase to another one (braking -acceleration, acceleration -braking). The next 1.4 meters 11 of moving off from the point of 2.6 meters 10 to the point of four meters 12 the acceleration will increase from 0% of pressing to 80% of pressing, i.e. if we divide 1.4 meters by 80% of pressing, then every 1.75 meters of moving off the acceleration will increase by 1%. However, if the point B will start to approach the point A, traffic control mode will keep on working in the same mode, but only in the opposite direction. S.

Figure 4 shows a laser ray I of traffic control system where the dispatch point is A 2, and the adherent point with the front vehicle is B 3.Total length of the ray from A to B is four meters. The first and second parts 4,5 from the point A are of the total length 2.5 meters and these are braking parts in the traffic control mode. The third part 6 of the length of 10 centimetres is inactive and serves as pause for successfiul switch oh the acceleration and brake mechanisms from one phase to another one (braking -acceleration, acceleration -braking).The fourth part 7 of the total length of 1.4 meters is the acceleration part in the traffic control system.
Figure 5 shows two vehicles 1,2. In the left vehicle 1 there is installed traffic control system with alternative radio measurer of the distance 3.This traffic control system functions according to the same principle as traffic control system with laser device described above. The difference is that the radio measuring device measures the distance between the vehicles due to the radio waves 4.
