In conjunction with the circuit structure of above-mentioned automobile automatic window-closing system, the invention allows for the control method of a kind of automobile automatic window-closing system, follow the steps below:
Step 1: microcontroller obtains the remote-control key signal of vehicle, when pressing remote-control key car locking key, microcontroller sends control signal, controls relay switch conducting so that automobile auto-power on triggering vehicle electronic device works；
Step 2: microcontroller obtains window locations signal, when vehicle window is in full closing state, enters step 3；Otherwise enter step 4；
Step 3: microcontroller sends control signal, controls relay switch and disconnects so that automobile automatically powers off, and stops powering to vehicle electronic device；
Step 4: vehicle window to vehicle window controller by automobile bus transmission pass window signal, is closed, and returned step 2 cycle detection by microcontroller.
The method is by bus detection remote-control key signal and window locations signal, and by controlling to allow by the way of relay the power output end in ignition switch module directly connect with vehicle power, even if pulling up key, vehicle electronic device can also live line work, now, microcontroller can be sent by bus and close window control command, promotes to close window controller and closes all vehicle windows.
The remarkable result of the present invention is: exported control signal by the moment of remote-control key closed door by microcontroller at automobile, triggers vehicle in short-term charged, then rises window order by automobile bus output, it is achieved rise window；The program and the original vehicle electronic circuit that need not the vehicle window controller to former car are transformed, and simple in construction is easy for installation；Meanwhile, rising window order is to send when original vehicle window controller electriferous state, and versatility is good.
