Technical field

The present invention relates to a kind of multifunctional running, stopping guide alarm system.

Background technology

People when driving, particularly reversing, park and line process in, the situation that often needs to observe vehicle periphery.When observing the car rear side, need rearview mirror, even also will pass through the car rear window by the vehicle both sides; When observing the car both sides, need car side window by the vehicle both sides; When observing the car front side, need by windscreen, unavoidable overcautious and indecisive, attend to one thing and lose sight of another.Existing various radar for backing car can only give the alarm when reversing in contingent tailstock collision, and monitoring range is little, and intuitive is poor.

" looking around display (Around View Monitor) " is emerging in recent years motor vehicle equipment, it is by 4 wide-angle imaging heads that are separately positioned on the car front, rear, left and right, take car scenery on every side from different perspectives, the gained vision signal is synthesized the car overhead view image of scenery on every side with computing machine, and this image is presented on the panel board.Monitoring range is bigger than radar for backing car, and intuitive is also good than radar for backing car.But this display of looking around can not demonstrate the imminent movement locus of vehicle, still has significant limitation.

The digital dial technology is to be applied to Robotics the earliest, and it can be converted into quantitative digital signal with rotatablely moving,

Summary of the invention

The technical problem to be solved in the present invention is the above-mentioned defective that how to overcome prior art, provides that a kind of monitoring range is big, intuitive good and can predict and demonstrate multifunctional running, the stopping guide alarm system of the imminent movement locus of vehicle.

For a definite vehicle, its track that advances is all only relevant with bearing circle with the track that falls back, unless under the situation that the hypervelocity sideslip is taken place.This is the preceding topic condition that any ripe vehicle all must satisfy.This just means that we can dope the imminent movement locus of vehicle according to the corner of bearing circle.

According to above-mentioned situation, multifunctional running of the present invention, stopping guide alarm system comprises that four are separately positioned on headstock, the wide-angle imaging head of the car both sides and the tailstock, be arranged on the display in the car and the computing machine that high speed image is handled stamen sheet (DSP) is housed, the wide-angle imaging head, display and computing machine and vehicle power connect into by lead and look around display (Around View Monitor), the vision signal of the vehicle periphery scenery that the wide-angle imaging head photographs from different perspectives, by the overhead view image of the synthetic vehicle's surroundings scenery of computing machine, and be superimposed with a vehicle figure that dwindles according to a certain percentage at the middle part of this overhead view image, be presented on the display together, it is characterized in that: it also comprises reverse gear sensor that is installed on backup lamp display circuit or the shift lever and the digital dial that is installed on the steering axle, and backing car gear information and the next direction information of digital dial transmission that described computing machine comes according to the reverse gear sensor transmissions simulate the possible movement locus of this car on described overhead view image.

So design before the use, at first according to the physical dimension and the design feature of the vehicle that is equipped with, is more properly said, according to the man-to-man relation that is the movement locus of the corner of steering axle and vehicle, sets up corresponding database in described computing machine.During use, described computing machine transfers the direction information that comes according to digital dial and access corresponding movement locus in described database.If this moment, backing car gear information shows that shift lever is on the reverse gear, then shows backing track on the overhead view image at described vehicle figure rear; If this moment, backing car gear information shows that shift lever is not on the reverse gear, then shows the track that advances on the overhead view image in described vehicle figure the place ahead.Other vehicles on these movement locus and overhead view image or hinder the barrier thing to overlap then have the danger that bumps, otherwise then can not.Described computing machine can be revised these movement locus in real time according to driver's operation, and is presented on the display synchronously.After high speed image was handled stamen sheet (DSP) and corrected, the image that shows on the display in car was normal vision image but not flake mirror image.Like this, the driver can obtain real-time caution directly perceived on display when turning, reversing, doubling, makes to drive to become simpler.

As optimization, it also comprises the headlight rotating mechanism, this headlight rotating mechanism comprises reversing switch, stepper motor and two normally closed reset switches that are separately positioned on the headlight left and right sides, they form reversible control circuit by associated tracks and vehicle power, cooperate by reducing gear between stepper motor and the headlight pedestal, the headlight pedestal under the drive of stepper motor M, left-right rotation within the specific limits.

So design, during driving at night, but the headlight left-right rotation has been eliminated dark dead angle, is convenient to give full play to the effect of this present invention multifunctional running, stopping guide alarm system.

As optimization, it also comprises stadimeter and the phonetic alarm that is installed in car head, the two all links to each other with described computing machine with vehicle-mounted knotmeter, when described computer monitoring arrives by this car speed per hour, this car and front vehicles or when hindering the range of driving of the not enough certain hour of distance that hinders thing, phonetic alarm sends language or buzzing is reported to the police.

So design, if set 2 second the range of driving be safe distance, when vehicle travelled with 110 kilometers/hour speed, per second advanced 30.6 meters approximately, 2 second the range of driving should be 61.2 meters.If this moment, stadimeter showed this car and preceding following distance less than 71.2 meters, described computer prompted sound will be near excessively with car by the phonetic alarm prompting, requires to slow down.Reduced so effectively the probability of rear-end collision has taken place, and helped the driver to find that early the place ahead hinders the barrier thing.

As optimization, described stadimeter is a laser range finder.So design is a good directionality of considering laser, the roadside can not isolated greening and think that the place ahead hinders the barrier thing by mistake.

After adopting technique scheme, multifunctional running of the present invention, stopping guide alarm system, have parking, reversing guiding, help to keep the track, night the dead angle according to multinomial functions such as, bright anti-warning of knocking into the back, be that a kind of monitoring range is big, intuitive good, also can predict and warn out multifunctional running, the stopping guide alarm system of the imminent movement locus of vehicle.Being widely used in multiple motor vehicle such as car, passenger vehicle, lorry uses.
