Number, wherein target control signal is one of the following: the power supply signal for being powered to second camera, automobile starting letter
Number, astern signal；Target control signal is sent to host by the 9th interface on pinboard, so that host executes and target
Control the corresponding response operation of signal.
For example, being the power supply for being powered to second camera (for example, front camera) in target control signal
In the case where signal, after receiving power supply signal, host can be powered to second camera.
For another example in the case where target control signal is vehicle activation signal, after receiving vehicle activation signal,
Host can send power supply signal to front camera by pinboard, to open front camera.
In another example after receiving astern signal, host can be in the case where target control signal is astern signal
It determines starting rear camera, obtains image information from rear camera.
Front camera and rear camera, OBD device talk interface, vapour may be implemented in above-mentioned technical proposal through the embodiment of the present invention
The integrated and customization of the furnishing multifunctionals such as vehicle enabling signal, power supply, antenna transmitting, provides not according to different user group
Same accessory, meets the individual demand of user.Meanwhile it also being provided a great convenience for the software and hardware upgrading of host.
