Accompanying drawing explanation
Fig. 1 is the system block diagram of the preferred embodiment according to this novel dynamic trajectory reverse image automatic control system.
Embodiment
In order to more deep understanding the utility model, enumerate one here and come further to explain according to a ride preferred embodiment of fare payment system of the utility model, the present embodiment only plays explanation illustration to the utility model, does not play any restriction.
Embodiment 1:
Present solution provides a kind of dynamic trajectory reverse image automatic control system, comprise microprocessor, display unit, camera, described system comprises memory, CAN, video chip and automatic control unit further, described CAN, memory, video chip, automatic control unit are connected with microprocessor respectively, described video chip is connected with camera respectively with automatic control unit, described display unit connects described video chip, and described microprocessor is connected with automobile body.Described automatic control unit comprises micromachine and transmission device, and described micromachine and transmission device control camera position, angle.Described CAN transmission direction dish angular signal is to microprocessor.Described memory stores reversing automobile trajectory picture.Described reversing automobile trajectory picture is that procedure simulation is formed.Described memory is FLASH memory.Described camera obtains rear view of vehicle image.Described camera is upper-lower position adjustable camera.Described camera is camera angle adjustable camera.Described video chip comprises Video Decoder, video encoder, image display.Described video chip transmits video standard signal to display unit.Described display unit comprises TFT screen.The image that described display unit display camera obtains and the video standard signal image comprising backing track picture.
As shown in Figure 1, wherein, display unit is display, and memory is FLASH memory.Wherein said memory, stores the reversing automobile trajectory picture formed through software program emulation.Described microprocessor, is connected with automobile body, obtains the angular signal of automobile body steering wheel, drives video chip, completes video display and overplay.Described video chip, enumerates Video Decoder, image display and the function of video encoder, completes the coding work of video standard signal of final display that camera obtains the conversion of picture signal, the generation of backing track picture and flows to display.Described display, the video standard signal image of camera image and backing track picture is finally included in display.Automatic control unit, comprises micromachine and transmission device, to be used for after microprocessor obtains the steering wheel angle signal message of CAN, controlling the position of camera and angle.CAN network: the automobile CAN-bus network including steering wheel angle signal, the angular signal of main outbound course dish.
In the present embodiment, automatic control system is according to the angular signal receiving automobile body steering wheel, and transfer reversing automobile track picture that is corresponding to angular signal and that be pre-stored within memory, corresponding reversing automobile track picture is combined with the image that camera obtains car rear, and pass through video encoder and show over the display, meanwhile, microprocessor according to the angle of the angular signal information of steering wheel by the automatic control equipment adjustment camera on camera, can increase effective image information of driver equally effectively.Therefore it can correspondingly transfer out concrete reversing automobile track picture and the angle of camera according to the angular signal of current steering wheel, thus there is the characteristic of dynamic trajectory and the effective image information of expansion, and then there is the effect that can improve driver's adjustment correct amount accuracy.
Wherein, automatic control unit includes the device for carrying out protecting control and its angle of adjustment to camera; the input of microprocessor is connected with the CAN for transmitting the various signal of automobile; camera connects video chip; the output port of microprocessor is connected with and carries out rotating the automatic control unit of hiding and carrying out when camera starts testing reversion work for controlling camera when camera does not carry out testing, and this automatic control unit can control by control unit 1 shooting angle adjusting camera equally.Microprocessor drives video chip according to the steering wheel angle signal message obtained, and allows the image of camera normally show over the display normally with this.Then microprocessor is again according to the steering wheel angle signal message that obtains from CAN network, and take out accordingly and be stored in the backing track picture of FLASH memory, after video chip process, Overlapping display is on final display image.
When engine keeps running, microprocessor always gathers the gear signal of automobile, vehicle speed signal and park mode signal by CAN.Backing car gear is selected when collecting automobile, and obtain speed information lower than under the condition of 15km/h, microprocessor starts to power to camera, now camera is opened and is worked, camera is adjusted to shooting angle just to automobile rear from stowed position by microprocessor driven automatic control unit simultaneously, now camera can collect the image at automobile rear and send image information to video chip, and vision signal is decoded and sent to display to show by this chip.Select reverse gear shift when microprocessor does not collect automobile or do not collect the speed of a motor vehicle lower than under the condition of 15km/h; microprocessor is not powered to camera; microprocessor transmits control signal to automatic control unit simultaneously; packed up by camera and be placed into stowed position, protection camera is avoided when not working being stained with by rainwater or dust.
Technical scheme described in the present embodiment provides a kind of dynamic trajectory rear camera displaying accessory system; driver cannot be reliably reminded to adjust the problem of correct amount to solve prior art reverse image accessory system; control camera by automatic control unit simultaneously; make it can protect the cam lens of reverse image device; while avoiding being stained with by rainwater or dust; the angle of camera can be adjusted equally, to provide larger effective image information for driver according to the angular signal of steering wheel.
Embodiment 2:
As different from Example 1, the present embodiment has carried out additional detail design on the basis of embodiment 1, for preventing backing track picture in the process being added to camera image, cover effective image, this backing track picture should do translucent process, and the effect be added in camera image is translucent effect.
In order to understand the utility model better, in conjunction with specific embodiments the utility model to be explained in detail above.But, obviously novelly can carry out different modification and remodeling and the novel wider spirit and scope of basis that do not exceed that claim limits to this.Therefore, above embodiment has exemplary and hard-core implication.
