Description
Technical field
The present invention is that a kind of measurable steerman is about to brake or the speed of a motor vehicle is about to ease up, and the brake forewarn system of being warned, particularly the forewarn system that reacts according to this relevant for a kind of operational motion that utilizes Das Gaspedal or oil door handle.
Background technology
Raising along with its people's quality of life, the quantity of automobile will get more and more, crowded degree is bound to more and more seriously on the road, but constantly increases the automobile number on limited road, can keep the reduction that good safety distance also can be relative in the middle of two chassis.With regard to the vehicle drive person, most driving time, advance at the vehicle of trailing the place ahead, also therefore cause and trail the 15%-20% that the overtaking collision incident accounts for all accidents.Because taking from the extraneous information that the car external environment obtained, steerman depends on " vision " more, steerman need constantly be watched the place ahead stoplight stop lamp reaction and left and right back mirror etc. attentively under steam, steerman is if will touch on the brake, normally light just and and then touch on the brake by feat of the stoplight stop lamp in the place ahead, the sensation of early warning is just arranged earlier before how allowing the driver vehicle brake lamp lighting forwardly, and this is a very important thing.
Yet in the middle of driving procedure, just in case when the front has situation to take place, the necessary brake that can be real-time of driver.Under present normal circumstances, during automobile is advanced, because we can't learn that what kind of situation is the place ahead vehicle condition of vehicle be at the moment, so stoplight stop lamp is unique clue of transmitting front truck brake message, and whether navigating mate fully all is to decide by the place ahead stoplight stop lamp oneself to touch on the brake.And it is more and more in automobile quantity, under the situation of the minimizing that car is also relative with the distance between the car, up to now, the stoplight stop lamp of automobile both sides behind car, increased the 3rd stoplight stop lamp (vehicle that has has also installed the emergency brake alarm additional), see also shown in Figure 1, known brake alarm function mainly is to follow to send caution according to the action of brake pedal, its flow process mainly is to judge whether steerman has used brake pedal (step 101), if brake pedal is used and then makes the action of lighting stoplight stop lamp (step 102) or the 3rd stoplight stop lamp; And if brake pedal when not depressed, then extinguishes stoplight stop lamp (step 103) or the 3rd stoplight stop lamp.
But above-mentioned these devices also all be the signal that the time just can occur in brake, if reduce causing of overtaking collision accident, just must improve navigating mate forwardly the vehicle brake lamp light alertness before.
On the other hand, because the external caution of present vehicle-state only has indicator, stoplight stop lamp or backing-up lamp etc., and undirected other steerman is warned the running condition of its throttle, limited because of the track of road again, when general vehicle uses road, often must trail other vehicle, therefore front truck stop to refuel back (pin does not leave Das Gaspedal as yet) and not changing step on brake pedal during, the speed of a motor vehicle will continue slow falling, between this phase buffer, the driving of front vehicle also can't obtain the prompting of any cresset, and back car steerman can only feel that front vehicles no longer quickens and respond with the mode of estimating.But normality will be in both sides dynamically advance (particularly high-speed motion), and the change of being estimated the speed of front vehicles by the rear is the difficulty that certain degree is arranged.Therefore, the steerman at rear tends to continue carry out the gas filed action, when shortening dramatically with the front truck spacing, side's vigilance front truck speed of a motor vehicle descends, and suddenly steps on brake, after front truck refuels again again by the time, after the back car speed of a motor vehicle dropped to a low speed already, the anxious again step on the gas of back car steerman was caught up with the front truck speed of a motor vehicle.Being the blasting fuse of a traffic accident during this section grey, also is the energy killer of a stealth, urges throttle because of anxious again after the speed of a motor vehicle rapid drawdown, is the mode of driving of oil consumption the most.And above-mentioned this kind sight ubiquity betides on one's body each steerman, hence one can see that, it is very huge that each day, the data of this section waste national energy took place, learn by experimental data, 10 the driving energy is arranged approximately, waste to refuel because of unknown front truck has had and do not continue step on the accelerator in this kind, to such an extent as to decelerations that must touch on the brake afterwards, and after the front truck acceleration situation of step on the accelerator suddenly again.
Therefore, as how failure-free mechanism, simple, the most direct mode are come according to vehicle-state, the speed of a motor vehicle of predicting vehicle one step ahead is about to the action that slows down or be about to brake, and send caution in advance, to warn other driving to step up vigilance, and the alertness before increasing the driver stoplight stop lamp lighting forwardly promptly becomes an important topic of saving oil consumption and improving traffic safety.
