Of the present utility modelly be achieved in that a kind of vehicle rollover real-time early warning device, it comprises microprocessing unit, is connected with front left wheel tyre pressure sensor, left back wheel tyre pressure sensor, right front wheel tyre pressure sensor, right rear wheel tyre pressure sensor, lateral acceleration sensor and warning device at microprocessing unit.
Warning device comprises annunciator, safety lamp, warning light, alarm lamp and telltale.
The utility model is at testing vehicle on basis of experimental, vehicle tyre tire pressure and lateral acceleration feature during according to the critical rollover of vehicle, use gas pressure sensor and lateral acceleration sensor and combined with intelligent controller that the vehicle in travelling is detected in real time, information liquor charging crystal display screen after the microprocessing unit processing is shown, so that chaufeur is had gained some understanding to the operation conditions of vehicle, when vehicle has rollover trend, warning device is reported to the police, chaufeur is taked corresponding measure immediately, avoid the generation of rollover accident, and provide the rollover early warning signal for later anti-laterally turning-over device, simultaneously, show by the real time data of LCDs for pressure of tire, when high pressure appears in tire, during low pressure, warning device can be pointed out chaufeur, and actv. reduces because the traffic accident of blowing out and leaking gas and causing improves drive safety.
Specifically, the foundation of main judgement rollover is pressure of tire and lateral acceleration.
Tire is one of vitals of automobile, and it directly contacts with the road surface and automotive suspension suffered impact when relaxing running car jointly, guarantees that automobile has good driving comfort and riding comfort; Guarantee that there is good tack on wheel and road surface, improve traction property, braking ability and the crossing ability of automobile; Bearing the weight of automobile.By the real-time monitoring of gas pressure sensor to pressure of tire, when the tire pressure in the tire was not in predetermined threshold, vehicle was in normal motoring condition; When the tire pressure in the tire was in predetermined threshold, vehicle had the trend that rollover takes place, but the possibility of tyre explosion or gas leakage is equally also arranged.Therefore, can not be simple as weighing automobile whether the standard that rollover trend takes place is arranged with pressure of tire.
The utility model uses the lateral acceleration of the real-time monitor vehicle of lateral acceleration sensor simultaneously, and the rollover condition is replenished and revised.Some extraordinary circumstances in the vehicle driving process during as the road surface of vehicle by pit, inclination, tire flat, can produce bigger influence to the pressure of tire of vehicle, if only with pressure of tire as the rollover factor, then warning is easy to generate wrong report.The utility model uses pressure of tire and lateral acceleration as the rollover factor, and when having only measured value when two factors all greater than predetermined threshold value, warning device just can be reported to the police.Compare the shortcoming of having broken away from the low and poor reliability of actual accuracy that the single rollover factor brings with other rollover forewarn system, its stable performance, particularity height, sensitivity is strong and have general applicability.
Microprocessing unit is judged the motoring condition of vehicle by obtaining the sensor data monitored, sensor is sent to microprocessing unit with real-time data monitored, microprocessing unit is brought these data into and is set in advance in the program of microprocessing unit inside, compare with the rollover threshold value that is preset in the microprocessing unit program, if when being in the rollover threshold value, warning device begins to report to the police.
Principle of work of the present utility model as shown in Figure 2, when starting vehicle, microprocessing unit starts, and begins to receive the signal that comes from sensor output.The lateral acceleration value that the pressure of tire value that microprocessing unit detection gas pressure sensor transmission in real time comes during work and lateral acceleration sensor transmissions are come, microprocessing unit compares these two values and predetermined threshold value, when they during greater than predetermined threshold value, microprocessing unit will be opened the switch of warning device, warning device is started working and is carried out sound and light alarm, be that annunciator sends the warning buzzing, the alarm lamp flicker.
The right half part of principle of work Fig. 2 is the back work part: the effect of this part is to judge the pressure of tire value, and informs chaufeur by Liquid Crystal Display (LCD).When the pressure of tire value was too high or too low, chaufeur will be reminded by system.Its condition precedent is that vehicle travels steadily, and namely lateral acceleration is close to 0 state.Shown in Figure 2 as principle, when microprocessing unit detects the pressure of tire value when too high or too low, whether detection side judges lateral acceleration close to 0 to acceleration pick-up again, if forecast that warning lamp will glimmer to remind chaufeur.
Method of the present utility model accurately and reliably, institute's employing components and parts technology maturation, volume is little; Stable work in work, particularity height, sensitivity are strong and have general applicability, need not existing vehicle is carried out big structural modification, are fit to all kinds and new old vehicle, have significant effect for the driving safety that improves vehicle.
Automotive suspension has two types, independent suspension and dependent suspension, difference according to suspension frame structure, come the patent of early warning vehicle rollover only to be applicable to the dependent suspension that steel spring has been installed based on the transverse load rate of transform and lateral acceleration value, and come the patent of early warning vehicle rollover not to be subjected to independent suspension and dependent suspension restriction (as long as there is the automobile of tire can based on pressure of tire value and lateral acceleration value, be the predetermined threshold value difference of every kind of vehicle), be applicable to all vehicles, Applicable scope is wider, and practicality is stronger.
