The method flow diagram of the embodiment that Fig. 2 provides for Vehicular multifunction method of controlling security of the present invention.
The object of the invention realization, functional characteristics and advantage will in conjunction with the embodiments, are described further with reference to accompanying drawing.
Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The structured flowchart of the embodiment that Fig. 1 provides for Vehicular multifunction safety control system of the present invention, as shown in Figure 1, Vehicular multifunction safety control system comprises camera 22 in drive recorder 21, car, car rear camera 23, telltale 26, prompting module 25 and control system 24, in described car, camera 22 is for taking picture in car and showing on the display 26, in the car that control system 24 is taken according to camera in car 22, picture judges that whether chaufeur is tired, work as driver fatigue, remind chaufeur to take care by prompting module 25; The rear view of vehicle close shot picture of shooting, for taking the close shot picture of rear view of vehicle, when control system 24 receives astern signal, shows, moves backward to make driver safety by described car rear camera 23 on the display 26.
In concrete enforcement, in the camera of described drive recorder 21, car, camera 22 and the view data captured by car rear camera 23 can be passed through after DSP transforms and export the data of MJPG form to MTK platform, and show on the display 26, conveniently see in car for chaufeur, car outer each orientation picture, avoid occurring blind area in driving procedure, to improve driving safety.
Preferably, as shown in Figure 1, described system also comprises storage unit 27, for preserving picture in car that camera 22 in car takes, and the car rear close shot of car rear camera 23 shooting or distant view picture, thus can be the research of subsequent design personnel and traffic accident etc. and carry out keeping records.
Preferably, described car rear camera 23 is also for taking the distant view picture of rear view of vehicle, for in vehicle advance process, the rear view of vehicle distant view picture of display shooting in real time on the display 26, be convenient to chaufeur like this and can observe car rear picture better, and when follow-up there is traffic accident time, the record preserved also can as evidence better.
In concrete enforcement, the present invention utilizes picture captured by the functional realiey drive recorder 21 of MTK two-way ISP and Che Nei camera 22 to show on the display 26 simultaneously; Car rear camera 23 adopts the picture-in-picture mode of usb protocol to show, described drive recorder 21 is connected with the mipi interface of MTK platform, in described car, camera 22 is connected with the DVP interface of MTK platform, and described car rear camera 23 is connected with the USB2.0 interface of MTK platform.
In concrete enforcement, described drive recorder 21 can adopt OV2710 model, power supply DVDD=1.5V, AVDD=3.3V, IOVDD=1.8V, and data-interface is the Mipi interface of serial; After sensor supply regular power, after the initialization of I2C, image information just can be transferred to MTK platform by sensor, shows through ISP process.
In described car, camera 22 can adopt GC1004 model, power supply DVDD=1.5V, AVDD=3.3V, IOVDD=1.8V; Data-interface be parallel port 8 position datawire DATE [2:9] and synchronizing signal VREF HREF; After sensor supply regular power, after the initialization of I2C, image information just can be transferred to platform by sensor, shows through ISP process.
Described car rear camera 23 can adopt OV9712 model, and it is post-tensioning USB camera, uses the power supply mode of 5V, the communication interface of USB; The interruption pin of USB connects the reverse of car, and during reversing, reversing line signal BACK is driven high, R1102 and R1103 is that signal voltage on BACK is too high punctures aerotron Q1101 in order to prevent; After the base stage of Q1101 is driven high, triode ON, OTG_IDDIG is converted into low level by original high level and interrupts; When MTK detection of platform is to the interruption of OTG_IDDIG, enter OTG pattern; Directly oppositely the VBUS of boosting 5V is to USB camera, and USB camera just can normally work, and by the car rear close shot picture display of shooting.
In concrete enforcement, the camera of described drive recorder 21 and Che Nei camera 22 are arranged on the position of rear view mirror in car on Windshield, and described car rear camera 23 adopts USB extended line to be pulled on vehicle trunk.
Described telltale 26 can adopt the existing back mirror of vehicle to realize, thus has saved system cost.
Present invention also offers a kind of vehicle, comprise Vehicular multifunction safety control system described above.
The method flow diagram of the embodiment that Fig. 2 provides for Vehicular multifunction method of controlling security of the present invention, as shown in Figure 2, Vehicular multifunction method of controlling security comprises the following steps:
Step 11, is also shown over the display by picture in camera shooting car in car;
Step 12, according to picture in the car of camera shooting in car, control system judges that whether chaufeur is tired; Step 13, works as driver fatigue, reminds chaufeur to take care by prompting module;
Step 14, by the close shot picture of car rear camera shooting rear view of vehicle;
Step 15, when control system receives astern signal, shows the rear view of vehicle close shot picture of shooting over the display, moves backward to make driver safety.
It should be noted that at this, above-mentioned steps 11 and step 14 precedence relationship not in life period, as shown in Figure 2, namely step 11 and step 14 can be run simultaneously.In addition, as the drive recorder that existing vehicle comprises, its function does not do concrete introduction in Vehicular multifunction method of controlling security of the present invention.
Preferably, described method also comprises, in vehicle advance process, also shown over the display by car rear camera captured in real-time rear view of vehicle distant view picture, be convenient to chaufeur like this and can observe car rear picture better, and when follow-up there is traffic accident time, the record preserved also can as evidence better.
Preferably, described method also comprises, by picture in the car of camera shooting in car, and the car rear close shot of camera shooting after car or distant view picture are saved in storage unit in real time, thus can be the research of subsequent design personnel and traffic accident etc. and carry out keeping records.
It should be noted that at this, described car rear close shot or distant view, it can by designer according to parameters such as the focal lengths of the concrete distance adjustment car rear camera of close shot or distant view, make in vehicle advance process, clearly take rear view of vehicle distant view picture (such as, the distance of distance vehicle is greater than 4 meters) in real time by car rear camera and show over the display; And when control system receives astern signal, the rear view of vehicle close shot picture (such as, the distance of distance vehicle is less than 4 meters) of shooting is clearly shown over the display, move backward to make driver safety.
Further preferably, described method also comprises, when chaufeur occurs sleepy, it is out of service that control system controls vehicle, and start two flashing light flicker, thus avoid vehicle to stop at suddenly express highway or other section that should not stop (road central authorities), and give below vehicle bring be caught unprepared and result in an automobile accident, therefore, this preferred version serves the effect reminding vehicle (this vehicle has an accident) below in advance, and then ensure that the safe operation of vehicle below.
It should be noted that at this, whether chaufeur there is fatigue, drowsiness, can be judged, because it by existing techniques in realizing, therefore can not do concrete introduction at this by image processor by identifying the pupil size of chaufeur.
Although the foregoing describe the specific embodiment of the present invention; but those skilled in the art are to be understood that; these are only casehistorys; various changes or modifications can be made to present embodiment; and not deviating from principle of the present invention and essence, protection scope of the present invention is only defined by the appended claims.
