Description

Automobile driving assisting system

Technical field

The invention belongs to a technical field of road traffic system.

Background technology

The applicant has urban road driving experience for many years, has experienced variations such as the restriction of city on " growing up ", road is more and more tighter, the traffic lights crossing is more and more.Steering vehicle is when the traffic lights crossing, and the indeterminate factor that will face in fact is a lot, in the face of these indeterminate factor drivers' the normal difficulty that judges between right and wrong, or even do not know where to begin.I say so not is to be complicated with asking, for example: automobile is come the traffic lights crossing three kinds of situations, the one, and red light is bright, or amber light is bright, or green light is bright.But the excess time of current cresset, automobile be to the concrete distance of traffic lights crossing stop line, with the feasible speed of a motor vehicle at present, whether the remaining cresset time enough by the crossing etc., and these factors all are very difficult judgements.When automobile is seen the front red light in different distance, different ways is arranged.Yes in the time of closely ramp to stop, this is sure.But when automobile when larger distance finds that red light is bright, the driver of different quality has different ways.Conservative steady driver yes release the gas pedal allows car slip to the traffic lights crossing, and carries out the preparation of braking at any time, does not only safety but also fuel-efficient like this.But radical driver has then taked distinct way.They are unwilling to wait for, can pass through the crossing when they will strive for changeing green light at once.So he has taked not slow down or accelerate to advance the way of racing against time; When the automobilist see be amber light the time, different drivers also has different ways, but with respect to red light and green light, its danger is less.The third situation is green light.This is a most dangerous comparatively speaking cresset, and its reason is that it is exactly to be reluctant to wait for that nearly all driver has a kind of psychology, and though seen the green light distance have want to take advantage of fast logical.Therefore their major part has all been taked the action that acceleration is passed through.Consequently apart near the getting one's wishes realized in crossing.Far away apart from the crossing, the result is that automobile just begins flicker near green light before the stop line of crossing, and will transfer amber light at once.So radical people takes a risk to have strengthened throttle for racing against time, the people who has little time soon is with regard to emergency brake.A lot of traffic hazards often just take place in this period.Acceleration is passed through is easy to knock the car that other directions are let pass, emergency brake be easy to cause rear-end collision etc.So how, could correctly pass through the traffic lights crossing, when I learned driving in driving school, master worker and teaching material were never taught when driving over the traffic lights crossing, how to tackle the correct method of various situations.

For being provided during by the traffic lights crossing to the driver, basis for estimation, people found out in the other method that traffic lights countdown device is installed of traffic lights.As if after the traffic lights countdown had been installed, came into plain view the excess time of each cresset, and this measure can provide very big help for the driver.But the fact is willing to not as the people that also its installation does not only make the traffic hazard at this crossing descend, and its traffic hazard incidence has been risen.It is also very simple in fact to trace it to its cause, and racing against time, being reluctant to wait for is most driver's mental habit, and particularly second, this hope was stronger when inverse soon.Though the driver has known the remaining time of traffic lights, the distance of the spacing traffic lights of oneself can't accurately be judged.Can the car of oneself during this period of time no bottom in the heart by crossing driver at this moment.So it is in fact little to driver's help that the traffic lights crossing of traffic lights countdown device has been installed.A second behavior is robbed in the acceleration that has but caused some drivers during only less than 10 seconds when green light excess time on the other hand, rob second behavior main cause of accident generation often, the accident rate that the traffic lights crossing of traffic lights countdown device is equipped with in its order rises on the contrary, and traffic lights countdown device should popular requirement have been cancelled in the green light crossing that therefore traffic lights countdown device much was housed originally.

According to traffic police's accident statistics, the traffic hazard in city mostly occurs and locates at the traffic lights crossing.Trace it to its cause be most drivers be unwilling ramp to stop, misjudgment and rob second etc. due to.The maximum characteristics of urban highway traffic are that traffic lights multichannel mouth is many, and some is local at a distance of less than 100 meters two traffic lights just being arranged.The traffic lights crossing is the confluce on two roads, and people press the commander of traffic lights, and it is freely suitable that the crossing becomes, and oral sex is connected with positive effect so traffic lights satisfy the need.

The restriction on more and more, the traffic law of the quantity of automobile and the road surface at present is more and more tighter, and the stress that the driver drives is increasing.Though various traffic signs are arranged on the road, but these traffic signs some by trees block, some has been contained in background, some has then been ignored by the driver of stress, caused the driver under unclear situation, to exceed the Maximum speed limit in highway section, stopped car in the highway section that restricted stop, fallen first-class in the highway section that no turns.The generation of these situations all is because due to the road conditions in the unclear current highway section of driver.Here said traffic information comprises the excess time, automobile current location of crossing each cresset of traffic lights various forbidding and and information warning etc. in the distance of traffic lights crossing stop line, the highway section.If on each car a device is arranged, can point out the road conditions in current highway section by the form that voice or literal show, the so sure pressure that alleviates the driver greatly, minimizing driver's illegal number of times reduces the generation of traffic hazard.Regrettably, do not have such system in the prior art at present.

Summary of the invention

For helping the driver to understand the instant road conditions in current highway section, the present invention has taked following measure: support is installed emitter in the roadside, emitter built-in highway section traffic information and/or connect the traffic lights controller and/or be connected to road traffic command centre; At automobile receiving trap is installed, receiving trap connects speed pickup and/or vehicle-mounted computer and/or built-in Satellite Navigation Set in the car.

The benefit of doing like this is the every highway section of automobile, can both receive " official " traffic information of the instant authority in this highway section, as the Maximum speed limit in this highway section, automobile current location apart from the distance of traffic lights crossing stop line and the excess time of current cresset etc.Simultaneously receiving trap can also carry out computing apart from the distance of traffic lights crossing stop line and current data such as the speed of a motor vehicle according to traffic lights excess times, automobile current location, and with operation result by forms such as voice, literal prompting drivers at current cresset under excess time, whether enough cover the automobile current location to the distance of traffic lights crossing stop line etc., for reference driver.If automobile is to point out information such as the title of this next outlet of highway section and distance on highway.When receiving trap connects vehicle-mounted computer, the Maximum speed limit data in current highway section can also be delivered to vehicle-mounted computer in addition, implement to force Maximum speed limit by vehicle-mounted computer.Can alleviate driver's labour intensity and the incidence of accident greatly like this.

Embodiment

Emitter can use different media, for example can launch ultrared, can launch visible light maybe can launch hyperacoustic etc.Here said emitter refers to: can store and handle traffic information, and can pass through above-mentioned medium, will have the digital signal of traffic information or the electronic installation that simulating signal is launched.The composition of emitter mainly comprises light or ultrasound wave emission power amplifier, modulation circuit, coding circuit, single card microcomputer MCU circuit etc.That the composition of emitter has is discrete component, that integrated circuit is arranged, have also that discrete component mixes with integrated circuit etc.; Single card microcomputer MCU array configuration can be divided into different bus structure, different internal storage structure, different port organization, different CPU and software configuration etc. again.When emitter need connect traffic lights controller and/or traffic control center, single card microcomputer MCU had also disposed communication port circuit, coding and decoding circuit etc.; This programme is less demanding to single card microcomputer, uses as long as can finish this programme that all is fit to of data transmission, data and logical operation function.And along with development of technology, be fit to the single card microcomputer that this programme uses, can get more and more; The power amplifier aspect uses different media can use different power amplifiers or radiating circuit according to system, and they can also can be made of integrated circuit discrete component equally.Along with development of electronic technology, constitute the spendable emitter of the present invention and can get more and more equally on the whole.

The form of receiving trap has varied equally, the medium that adopts according to emitter for example, and correspondingly adopting can be receiving infrared-ray, that can receive visible light, it is hyperacoustic etc. to receive.Here said receiving trap refers to receive by emitter and sends, and has the visible light or the signals such as infrared ray or ultrasound wave that represent traffic information, and can reduce and handle contained traffic information, has the electronic installation of control, Presentation Function simultaneously.The composition of receiving trap mainly comprises reception head, demodulation coding circuit, single card microcomputer MCU circuit, data communication port circuit, voice power amplifier and display circuit etc.When emitter and traffic lights were contained on the support of same roadside, for tackling this situation, receiving trap also should comprise range-measuring circuit.Receiving trap is with its signal from emitter by receiving, and the distance of measured automobiles and emitter calculates automobile to the distance between the stop line of traffic lights crossing again according to the distance that records; The composition of these electronic installations or circuit has different forms, if any discrete component, that integrated circuit is arranged, also have that discrete component mixes with integrated circuit etc.Along with development of electronic technology, the combination of the spendable receiving trap of the present invention can get more and more.Single card microcomputer MCU array configuration can be divided into different bus structure, different memory construction, different port organization, different CPU and software configuration etc. again.This device is less demanding to single card microcomputer, uses as long as can finish the suitable this programme of having of data transmission, data and logic fortune function.And along with development of technology, the single card microcomputer that is fit to this programme use can get more and more.

This programme mainly is made of roadside support 1, emitter 2, receiving trap 3, automobile 4, as shown in Figure 1; Here said traffic information mainly comprises the road surface situation in current highway section, for example traffic lights excess times, automobile current location to distance, the Maximum speed limit in highway section of traffic lights crossing stop line, no turns in the front, the front is school zone, front zig zag etc.In order timely and accurately these information to be passed to driver through this highway section, this programme has been installed roadside support 1 on the highway limit, and emitter 2 is installed on the roadside support 1.Because emitter 2 is built-in partly traffic information so emitter 2 can work alone, also can connect the traffic lights controller and/or connect traffic control center.At automobile 4 receiving trap 3 is installed, in order to make receiving trap 3 can obtain the current vehicle speed data and to carry out data transmission and control.Receiving trap 3 connects speed pickup and/or vehicle-mounted computer and/or built-in Satellite Navigation Set in the car.

Be example with Fig. 1, when automobile 4 drove to roadside support 1 below, receiving apparatus 3 received the road section information that is sent by emitter 2.Here this information spinner will comprise that this highway section Maximum speed limit, automobile current location are to the actual distance of red green mouth stop line and traffic lights excess times etc.After receiving trap 3 receives these information, handle these information by blas at once.As by voice or the Maximum speed limit in the current highway section of text prompt, current cresset excess time and automobile 4 apart from the distance of traffic lights crossing stop line etc.Because receiving trap 3 has connected in the car speed pickup or built-in Satellite Navigation Set, and the current vehicle speed data have been obtained there from them, so receiving trap 3 can be according to these information calculations under the current vehicle speed or under the Maximum speed limit, whether there is the sufficient time to cover this segment distance from current location to traffic lights crossing stop line.If the time is enough, the driver can continue to advance with the current speed of a motor vehicle so, if deficiency of time receiving trap 3 can notify the driver to note with the form of voice, literal by blas.After the driver has notice, can select release the gas pedal to advance by the mode of automobile slide.Automobile is accurately judged by receiving trap by the traffic lights crossing in which way like this, has solved driver's dilemmatic embarrassment in this case in the past.

When support 1 emitter 2 in roadside was contained on the highway and connects traffic control center, emitter can be pointed out Maximum speed limit current, this highway section at that time, the next title that exports and distance etc. to the driver.Traffic control center can be adjusted the Maximum speed limit in highway section at any time according to situations such as weather, can make traffic control center more more specifically timely to the management of highway like this, has also improved traffic safety simultaneously.

The highway in a lot of mountain areas is curved anxious, tiltedly long.Running car is not driven over the speed limit owing to a lot of drivers carry out Maximum speed limit when falling tiltedly again the highway of zig zag, and hypervelocity often becomes the main cause that accident takes place.If roadside support 1 and emitter 2 are installed in the beginning in such highway section, have the traffic information of forcing the speed limit code by them to the receiving trap emission on the automobile of passing by.By the receiving trap on the car and vehicle-mounted computer automobile is carried out and to be forced speed limit, automobile to be forced to sail in that the safe speed of a motor vehicle is descending, the road accident rate in this highway section is declined to a great extent.

When if emitter and traffic lights are contained in same roadside support, just the range-measuring circuit of installing on the receiving trap uses.During automobile approaching traffic lights certain distance, receiving trap receives emission and puts the signal that has traffic information that sends.The range-measuring circuit of installing on the receiving trap records the distance of automobile and emitter by this signal, thus calculate automobile to the distance of traffic lights crossing stop line.After having obtained these data, receiving trap just can be organized work by blas.
