Specific embodiment
In order to describe the technical content, the structural feature, the achieved object and the effect of this invention in detail, below in conjunction with embodiment
And attached drawing is cooperated to be explained in detail.
Referring to Fig. 1, embodiment of the present invention discloses a kind of automobile trunk method for controlling opening and closing, which is characterized in that
Include:
Judge whether to detect the Intelligent key of vehicle and Intelligent key whether be less than at a distance from vehicle it is default away from
From；
If detecting the Intelligent key of vehicle, and Intelligent key is less than pre-determined distance at a distance from vehicle, then enable to set
The laser emitter for being placed in vehicle tail projects multiple hot spots on the ground of vehicle tail；
Whether jumped according to the output signal of inductor corresponding with each hot spot, and the number jumped and
Time sequencing calculates the unlocking code that user blocks hot spot；
Judge whether the unlocking code and the unlocking code for being pre-stored in car are consistent, if so, unlock vehicle trunk,
If it is not, not understanding lock vehicle trunk then.
As shown in Fig. 2, the scheme of installation of laser emitter and inductor, in the present embodiment, laser emitter 2 with
Inductor 3 is all set in the lower section that insurance after automobile shoulders 1.As shown in figure 3, ground upslide of the laser emitter 2 in automobile tail
Mono- column hot spot 4 of A~F is penetrated, the corresponding hot spot 4 of each inductor 3, for detecting whether hot spot position is hidden by user
It keeps off, the dashed circle 31 in Fig. 3 is the corresponding induction zone of inductor 3.It (is blocked with foot) when user blocks hot spot 4, it is corresponding
The output signal of sensor 3 will jump.Therefore, user is by blocking different hot spots, and the sequence and number blocked,
Coding input can be carried out, and whether is jumped by the output signal of the inductor of detection inductor, and jump
Number and time sequencing, can calculate user input unlocking code.For example, a unlocking code prestored is AACFFE,
The corresponding sequence for blocking hot spot are as follows: continuously block hot spot A twice blocks hot spot C again, then continuously blocks hot spot F twice, most
After block hot spot E.
The boot unlocking method is additionally arranged laser emitter, inductor and data processing ECU in the existing vehicles, swashs
Optical transmitting set on the ground of vehicle tail for projecting multiple hot spots, and the number of inductor is corresponding with the number of hot spot, often
A inductor is for detecting whether one of hot spot is blocked, and when hot spot blocks, the output signal of corresponding inductor is just
It can jump.Therefore by detection inductor output signal whether occur jump can be detected out corresponding hot spot whether by
It blocks, and whether the output signal by detecting different laser pickoffs jumps, and the time sequencing jumped, i.e.,
The sequence which hot spot is blocked and hot spot is blocked can be analyzed, so as to obtain sequence of the user when blocking hot spot,
That is unlocking code.
Wherein, the inductor can be pyroelectric infrared sensor, laser pickoff (i.e. laser pick-off pipe) or distance
Inductor (such as reversing radar).
Wherein, hot spot is detected according to the infrared signal that human body (i.e. the foot of user) is issued in pyroelectric infrared sensor
Whether position is blocked, and the laser of the sent out projection of laser emitter is to play input guiding function.
If the inductor be laser pickoff, when hot spot is blocked occur reflection (when hot spot is not blocked,
It can reflect, but the distance of reflection point is farther out, therefore the intensity of signal received by laser pickoff is also weaker, therefore,
Can also further judge whether hot spot is to be blocked by artificial according to the amplitude of the signal of laser pickoff output), thus right
The laser pickoff answered is received, and the laser of the sent out projection of laser emitter at this time is other than playing input guiding function, also
Play the role of signal source.
And whether working as inductor is distance-sensor, changed by detecting distance detected by each inductor, i.e.,
Whether detectable hot spot is blocked.
This automobile trunk unlocking method is by judging Intelligent key at a distance from vehicle and user is in vehicle tail
The unlocking code inputted on ground carries out car door unlock, not only easy to use, but also realizes the double of Distance Judgment and coding
Re-authentication improves safety coefficient.Also, unlocking code be it is modifiable, can be arranged and be pre-deposited by user oneself, be not easy
It is cracked.The present invention can also save the wireless key sharing electron module in car key, not use changeless wireless solution
Code-locked is unlocked.And the present invention uses laser emitter projected spot on the ground, and detects user by inductor and exist
The unlocking code that hot spot is blocked on ground, is not only simple in structure, low in cost, and realizes the function that unlocking code is inputted outside vehicle

Single instruction, such as the unblock button on door handle, the door opening key on boot).
In the present embodiment, the laser emitter is single laser emitter, passes through the shading being arranged in its front end
Piece, to project hot spot of different shapes, the laser that laser transmitter projects go out passes through anti-dazzling screen and projects single-row light on the ground
Spot.In other embodiments, the laser emitter is composed of multiple LASER Discharge Tubes, and the hot spot is in addition to this reality
The distribution of array used in mode is applied, it in other embodiments can also be using other arrangement modes such as nine grids.
In the present embodiment, described when detecting automobile intelligent key at a distance from automobile less than 10 meters, it enables to swash
Optical transmitting set projected spot, and in other embodiments, the distance can be 8 meters, the other values such as 12.
It further, in one embodiment, is the anti-interference for improving inductor, as shown in figure 4, in each inductor
3 front ends are also provided with the cone 32 of taper, and each cone 32 is directed toward the position where corresponding hot spot, thus prevents it
Interference of the reflection light of his hot spot to laser pick-off pipe.
In the above-described embodiment, after unlocking vehicle trunk further include:
The hot spot that three different patterns are projected on the ground of vehicle tail, it is crack, half-open and complete to respectively correspond boot
Open three different open states；
Whether logical inductor detection hot spot is blocked, and when hot spot is blocked, opens by open state corresponding to the hot spot
Open boot.
Referring to Fig. 5, being a kind of block diagram of automobile trunk opening control system of embodiment of the present invention, the arrangements for automotive doors
System for unlocking includes automobile intelligent key, laser emitter, inductor and data processing unit, and laser emitter and inductor divide
It is not connected to data processing unit, laser emitter and inductor are set to vehicle tail, each caused by laser emitter
