Description

A kind of tire burst safety prompting system
Technical field
The present invention relates to running safety method field, particularly pressure of tire, temperature monitoring and safety instruction technology specifically refer to a kind of tire burst safety prompting system.
Background technology
Pressure of tire receives the automobile industry and the public's concern to the influence of running safety always, and tire pressure monitoring system (TPMS) has become automobile apolegamy or standard configuration product.The mainstream technology scheme of TPMS is: TPMS is made up of two parts: the long-range tire pressure monitoring module that is installed in the wheel tyre cavity (contains the transmission of tire pressure monitoring and signal, RTPM:Remote Tire Pressure Monitoring.) and be installed in the central monitor (LCD display) in the operator's compartment.Central monitor receives the information of processing remote tire pressure monitoring module emission, and data such as each tire pressure and temperature are presented on the liquid crystal display successively, supplies the chaufeur reference.If data such as tire pressure or temperature occur unusual, central monitor sends different alerting signals according to abnormal condition, reminds chaufeur to take measures necessary.
The function of TPMS is that tire pressure is monitored; Remind chaufeur to note keeping normal tire pressure; Main technical requirements is: abnormal tyre pressure information should be sent early warning signal in 6 seconds; Gas leakage information should be sent early warning signal in 1 minute fast, and central monitor sends early warning, alarm message with forms such as graphic display, data display or sound and light alarms to chaufeur.
Summary of the invention
The purpose of this invention is to provide a kind of tire burst safety prompting system; Existing problems and deficiency to existing TPMS technology; Propose a kind of tire burst safety prompting system that is different from TPMS, comprise long-range tire pressure monitoring module that is installed in the wheel tyre cavity and the central controller that is installed in the operator's compartment.Wherein:
Described central controller has the tire burst safety prompting function; When real-time tire pressure data P≤dangerous tire pressure setting threshold Py in the information that receives, occurring; At once make " STOP " or " brake " voice suggestion, prompting guiding chaufeur is implemented the brake deceleration action.
Described central controller has the tire burst safety prompting function and is meant: when real-time tire pressure data P≤dangerous tire pressure setting threshold Py appears in central controller in the information that receives; At once make " STOP " or " brake " voice suggestion, but not the demonstration of tire pressure data message, voice suggestion, graphic display or sound and light alarm.After making the " STOP " voice, confirm voice suggestion content subsequently according to the real-time tire pressure data P in the information packet again, if 0Kpa<P≤Py, voice suggestion is " gas leakage fast of XX wheel ", if P=0Kpa then does " the XX wheel is blown out " voice suggestion.
Described real-time tire pressure data P≤dangerous tire pressure setting threshold Py can be drawn information computing judgement by central controller, also can be to judge the characteristic tire pressure data that send the back by long-range tire pressure monitoring module samples, computing.
Tire burst safety prompting system of the present invention; Comprise long-range tire pressure monitoring module that is installed in the wheel tyre cavity and the central controller that is installed in the operator's compartment; This and prior art TPMS technical products basically identical in topology layout, the difference difference of technical scheme of the present invention and TPMS technical scheme exists:
The central controller of technical scheme of the present invention has the different of essence with the central display unit of TPMS, and the TPMS central display unit is only born the information that receives is carried out graphic display, data display or sound and light alarm, does not do logic determines and handles.Technical scheme functional requirement of the present invention is positioned at safety instruction, need pass through data operation and logic determines whether safely, and therefore, the central controller of technical scheme of the present invention has data operation and logic judging function, and representative type ECU characteristic is arranged.
The tire burst safety prompting function of technical scheme of the present invention is to be provided with like this and to realize: (tire pressure data P≤dangerous tire pressure setting threshold Py can be judged the information computing by central controller and draw in real time, also can be to judge the characteristic tire pressure data that send the back by long-range tire pressure monitoring module samples, computing when central controller receives the real-time tire pressure data of the information packet P that long-range tire pressure monitoring module sends≤dangerous tire pressure setting threshold Py (like 80Kpa).), central controller is made the " STOP " voice suggestion at once.
Why technical scheme of the present invention makes " STOP " but not " blowing out " or " gas leakage fast " voice suggestion or sound and light alarm; Be because chaufeur when driving to external world information react and need a reaction and judgement process, reaction and judgement is consuming time to have direct relation with the information content, if chaufeur is heard the voice suggestion of " the XX wheel is blown out "; He need make judgement and select as form; He possibly select the bearing circle of holding with a firm grip, also possibly select to unclamp accelerator (throttle) pedal, perhaps selects brake deceleration; Even he is because alarmed and what is not done; This has just caused the meaningless prolongation of reaction and judgement time, even false judgment and reply occur, and having wasted can the self-quality time of succouring after blowing out.
And being provided with central controller, technical scheme of the present invention makes the " STOP " voice suggestion at once at the real-time tire pressure data of the information packet that receives P≤dangerous tire pressure setting threshold Py; Chaufeur can be implemented brake deceleration by the light of nature after hearing the " STOP " voice suggestion; And other selection can not appear; In fact the " STOP " voice suggestion makes brake at the guiding chaufeur, and this and autonomous cruise speed system are implemented brake has similar effect.Certainly; Because chaufeur is cue-response time need 600ms consuming time to external world, implementing brake also needs to add up to consuming time near 1s about 300ms consuming time; Implement brake than autonomous cruise speed system obvious delay is arranged; But because tyre explosion takes place to cross-up there is 3s~5s time, chaufeur can be implemented brake about 1 second under the safety instruction guiding of technical scheme of the present invention; Safety self-saving and dissolve the disaster consequence of blowing out and possibly cause, this is the cause that technical scheme of the present invention is referred to as tire burst safety prompting system.
After central controller is made the " STOP " voice suggestion, the more real-time tire pressure data P numerical value in the information packet is carried out analysis and judgement, if 0Kpa<P≤Py, central controller is done " gas leakage fast of XX wheel " voice suggestion; When P=0Kpa, central controller is then done " the XX wheel is blown out " voice suggestion.
The present invention has following beneficial effect:
The present invention's specially designed " occur real-time tire pressure data P≤setting threshold Py in the information that central controller receives and make the parking voice suggestion at once "; Chaufeur there is the safety instruction guide function of obviously confirming; Can point out the guiding chaufeur to make correct safety measure, brake deceleration is to avoid the back disaster accident generation of blowing out.
If central controller is made the voice suggestion of " the XX wheel is blown out "; Chaufeur need carry out necessary judgement to information just can make cooresponding conduct; Under the influence of original " can not brake after blowing out " idea, chaufeur maybe be because alarmed and do not go out brake or misoperation.And after chaufeur hears the voice suggestion of " STOP "; He need not the information content is done any judgement, and his first reaction promptly is to implement brake, makes the delay that there is nearly 1s the brake time though chaufeur is actual; But because tyre explosion to accident has 3~5 second time between taking place; Chaufeur is implemented brake under the " STOP " voice suggestion is guided, can reduce greatly and blow out back disaster accident generation even stop the accident generation, and this is that prior art TPMS is not available.
