Abstract
The invention discloses an automobile rear-end collision preventing system. The automobile rear-end collision preventing system comprises an electronic control unit, a laser ranging module, a warning module and a display device. The laser ranging module comprises an invisible laser emitting device, a laser receiving device and a laser encoder, wherein the invisible laser emitting device and the laser receiving device are arranged at the forefront of an automobile head. The laser ranging module, the warning module and the display device are respectively connected with the electronic control unit. The display device displays information about the current distance between an automobile provided with the automobile rear-end collision preventing system and a front automobile in real time. When the distance between the automobile provided with the automobile rear-end collision preventing system and the front automobile measured by the laser ranging module exceeds multiple preset safe-distance parameters stored in the electronic control unit, the warning module and the display device cooperatively give an audible and visual alarm.
Description
Technical field
The present invention relates to a kind of automobile safety system, be specifically related to a kind of automobile anti-rear end collision system, belong to automotive field.
Background technology
Motor traffic accidents is multiple at present, wherein rear-end collision accounts for the ratio of quite a few, in fact when safety traffic, as long as with front truck maintenance safety distance at least, the multiple safety distance under different road conditions more specifically, for example when dense fog or rainy day, the safety distance of safety distance during than general weather is more little, can significantly reduce the occurrence probability of this type of traffic accident, still, even chaufeur has been remembered multiple safety distance, can only judge that roughly the distance of this car and front truck is whether beyond safety distance by range estimation in motion, so error is very big, and two owing to idea of leaving things to chance, and chaufeur not necessarily can be made correct reaction.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of automobile anti-rear end collision system, it is in conjunction with existing safe space between motorcars empirical data, provides more accurately leading vehicle distance to measure and driver hedging in time initiatively.
To achieve these goals, the present invention is by the following technical solutions:
A kind of automobile anti-rear end collision system, comprise car running computer, the laser ranging module, alarm module, read out instrument, wherein this laser ranging module comprises invisible laser beam emitting device, laser receiver and laser encoder, the invisible laser beam emitting device of this laser ranging module and laser receiver are arranged on headstock position foremost, this laser ranging module, alarm module is connected with car running computer respectively with read out instrument, read out instrument shows range information current and front truck in real time, when the distance of reality that the laser ranging module detects and front truck surpassed the default a plurality of safety distance parameter of storing in the car running computer, alarm module cooperation read out instrument was made sound and light alarm.
Preferably, headstock foremost the position and car running computer in be respectively arranged with wireless transmitter, it connects by radio communication mutually, one of them wireless transmitter is connected with laser receiver with invisible laser beam emitting device, with transmit that the laser ranging module detects with the relative distance information of front truck and the operating order of car running computer.
Preferably, store default a plurality of safety distance parameters in the described car running computer, its each the riving condition with different is relevant respectively.
Preferably, also be provided with rain sensor, fog sensor with the car running computer communication on the automobile, car running computer transmits the environmental physics amount of returning according to rain sensor, fog sensor respectively, judges current riving condition and selected corresponding safety distance parameter.
The invention has the beneficial effects as follows: on the one hand, range observation is more accurate; On the other hand, remind chaufeur to keep and leading vehicle distance constantly, avoid chaufeur not make correct response because of idea of leaving things to chance.
The specific embodiment
Embodiment according to automobile anti-rear end collision of the present invention system, comprise car running computer, the laser ranging module, alarm module, read out instrument, wherein this laser ranging module comprises invisible laser beam emitting device, laser receiver and laser encoder, the invisible laser beam emitting device of this laser ranging module and laser receiver are arranged on headstock position foremost, this laser ranging module, alarm module is connected with car running computer respectively with read out instrument, read out instrument shows range information current and front truck in real time, when the distance of reality that the laser ranging module detects and front truck surpassed the default a plurality of safety distance parameter of storing in the car running computer, alarm module cooperation read out instrument was made sound and light alarm.
Preferably, headstock foremost the position and car running computer in be respectively arranged with wireless transmitter, it connects by radio communication mutually, one of them wireless transmitter is connected with laser receiver with invisible laser beam emitting device, with transmit that the laser ranging module detects with the relative distance information of front truck and the operating order of car running computer.
Preferably, store default a plurality of safety distance parameters in the described car running computer, its each the riving condition with different is relevant respectively.
Preferably, also be provided with rain sensor, fog sensor with the car running computer communication on the automobile, car running computer transmits the environmental physics amount of returning according to rain sensor, fog sensor respectively, judges current riving condition and selected corresponding safety distance parameter.
The above is preferred embodiment of the present invention, and the present invention is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present invention with identical means, all should belong to protection scope of the present invention.
