Abstract
The utility model discloses an automobile rear-end collision prevention safety warning device, which comprises a distance detecting device, a speed detecting device, a centralized device, a display device, an acoustooptical warning device, and a power supply, wherein, the centralized device processes data input by the distance detecting device and the speed detecting device, and transmits a processed result to the display device and the acoustic-optical warning device. During operation, the automobile rear-end collision prevention safety warning device can calculate the safety distance kept between the automobile and the forward automobiles or obstacles according to the speed of the automobile, and then compare calculated data with distance data in real-time measure. As long as the real automobile distance is less the safety distance, automobile rear-end collision prevention safety warning device can warn by an acoustic-optical way. The measured real distance and the safety distance are displayed to a driver via the display device. Therefore, the driver can know about real conditions visually.
Description
Technical field
The utility model relates to a kind of automobile anti-rear end collision safety prewarning apparatus.
Background technology
Along with economic development, the quantity that road is got on the car when the modern transportation instrument offers convenience for people's trip, has also been brought certain potential safety hazard for people in rapid increase.Chaufeur relied on technology of self and experience to guarantee shape car safety usually in the past, and different people, the experience difference, it is low that driving technique also has height to have, especially to fresh driver, driving experience is not known where to begin, when even if old driver also has error in judgement, automotive performance, road conditions are all in continuous variation in addition, therefore, only rely on the chaufeur self diathesis can not fully guarantee safety traffic, how to provide safeguard for safety traffic technically, the generation that tries to forestall traffic accidents becomes a problem that presses for solution.
The utility model content
At the prior art situation, the purpose of this utility model provides a kind of automobile anti-rear end collision safety prewarning apparatus, and this device carries out safe early warning automatically according to this car speed of a motor vehicle and with the distance of front vehicles or obstacle, exercises with the safety that guarantees vehicle.
For achieving the above object, the utility model automobile anti-rear end collision safety prewarning apparatus comprises:
One distance measuring equipment (DME) is used for the distance between this car of The real time measure and front vehicles or the obstacle;
One speed measuring device is used to measure this car speed of a motor vehicle;
One centralized control device, this device are a micro controller system, the data of distance measuring equipment (DME) and speed measuring device input are handled, and result is transferred to read out instrument and acoustic-optic alarm;
One read out instrument, this device is used to show the distance of being measured for liquid crystal indicator or LED read out instrument, also can show the safety distance that should keep simultaneously;
One acoustic-optic alarm under the control of centralized control device, when practical measurement distance less than the safety distance that should keep the time, is reported to the police in the acousto-optic mode;
One power supply is distance measuring equipment (DME), centralized control device, read out instrument and acoustic-optic alarm power supply.
Further, also comprise sensitivity selecting switch, this switch and described centralized control device join, and are used for determining the data processing mode of centralized control device.
Further, described distance measuring equipment (DME) is laser rangefinder or micro-distancer or ultrasonic range finder or infrared ambulator.
Further, the mechanical type or the electronic type speed measuring device that carry for this car of described speed measuring device.
During the work of this device, at first calculate a safety distance that should keep with front vehicles or obstacle according to this car speed of a motor vehicle, then this computational data and the range data that records are in real time compared, in case actual spacing less than safety distance, is then reported to the police in the acousto-optic mode.After the actual distance that records and safety distance be shown to chaufeur by read out instrument, can make it understand actual conditions intuitively.
Description of drawings
Fig. 1 constitutes scheme drawing for the utility model.
The specific embodiment
As shown in drawings, distance measuring equipment (DME) adopts the semiconductor laser range instrument of Changzhou Lai Sai company development, the car speed sensor that speed measuring device utilizes this car dress to be made of Hall element, the centralized control device adopts micro controller system, read out instrument adopts the Liquid Crystal Display (LCD) that carries driver module, and acoustic-optic alarm is made of buzzer phone and LED light-emitting diode, and sensitivity driving switch and micro controller system join, be used to change the computation schema of micro controller system or the safety rate of setting, whole device is powered by vehicle power.
Wherein distance measuring equipment (DME) also can adopt commercially available ultrasonic range finder or micro-distancer or infrared ambulator, and read out instrument also can adopt the commercially available telltale of being made by the LED light-emitting diode.
During installation, apomecometer is installed in car front bumper place, wind shelves inboard was convenient on the position of driver's observation before Liquid Crystal Display (LCD) was fixed on.
During use, chaufeur is adjusted to the appropriate location according to the speed of response of oneself with the sensitivity driving switch, energized, and whole device is promptly in running order.Along with vehicle launch moves ahead, car speed sensor, apomecometer are given micro controller system with vehicle speed data and distance measuring structure real-time Transmission, micro controller system calculates corresponding safety distance according to the speed of a motor vehicle in real time according to the pattern of setting, and the vehicle distance data of these safety distance data and The real time measure compared, meanwhile safety distance data and actual measurement vehicle distance data are come out by liquid crystal display displays.In case when occurring actual measurement spacing numerical value less than the safety distance value, micro controller system is exported corresponding alerting signal to acoustic-optic alarm, reminds chaufeur to note maintaining safe distance by warning device.
Chaufeur is in the steering vehicle process, when finding that unforeseen circumstances appears in the place ahead, from its discovery situation to taking brake measure to divide four-stage, that is: reaction time 0.6s～1.0s, brake-pedal clearance elapsed time 0.2s, braking force increases time 0.2s gradually, and braking force reaches the braking time that needs after the maximum, and wherein quadravalence section required time depends on the initial velocity of vehicle.Preceding two stages, the phase III becomes slowed down all less than slowing down, and the quadravalence section is even slows down, and the travel distance addition of four-stage vehicle is safety distance under the perfect condition.In fact, vehicle braked distance also is subjected to the influence of factors such as weather condition, condition of road surface, therefore must desirable safety distance also to leave certain margin of safety on the basis, multiply by 1.2 or higher safety factor etc. as ideal value.The weather conditions, road surface factor that influence car brakeing distance chaufeur often are not easy accurately to judge, add that chaufeur can not see speed meter all the time, therefore, as safety distance grasp, the experience that only relies on the people is not enough, traffic accident is greatly arranged, because the error in judgement of chaufeur causes.Use the utility model to overcome to think the influence of factor, provide objective secure data for chaufeur, thereby provide safeguard for safe driving by equipment.
