Several functions of the vehicle key 6:

1. when a single door is opened and the vehicle needs to enter under certain chaotic conditions, the danger can be met by opening all the doors at once, and then the arrangement can be carried out to open the cab door once and open the whole door twice.

2. The window closing function after flameout, the key 6 of many cars at present all has been equipped with the window of closing after flameout, only need press the lock car button, then the door window will automatic closing. And some vehicle types can be realized only by pressing a locking button for a long time.

3. The trunk is automatically opened, some cars continuously press the trunk twice, and some cars continuously press a control button of the trunk for a long time, so that the trunk can be opened.

4. The remote control window opening is carried out, when a user needs to get on the vehicle in summer, the interior of the vehicle is muggy, remote control can be carried out, all windows of the vehicle are opened firstly, and therefore muggy air in the vehicle can be released when the vehicle does not run.

5. Car search in parking lots, pressing the lock button twice (or even more) in succession, the car will tell you where to go with a very harsh whistling sound and a flashing double flash, in order to find his car quickly in places where there are more cars. Or when the dark underground parking lot is in trouble or danger, help can be sought in the mode.

The control signal of the automobile key 6 can be connected with the main controller 1 through a wireless network, the main controller 1 sends the control signal to each automobile door, the sub-controller 2 and the sub-controller 3 can be connected through the wireless network, the sub-controller 2 and the sub-controller 3 directly control the action of the electric load device in the automobile door, corresponding functions are achieved, and the calculated amount of the main controller 1 can be reduced.

In one embodiment, when the key 6 and the main controller 1 simultaneously transmit the control signal through the wireless network, the sub controller 2 and the sub controller 3 are subject to the control signal of the main controller 1. In the in-service use process, there is the driver to give control signal through main control unit 1 in the car inside, the outside other personnel of car hold key 6 simultaneously and send control signal, when the order that two control signal carried out is opposite, can lead to the unable action of electric load device or the action card pause appears, consequently when key 6 and main control unit 1 send control signal through wireless network simultaneously, secondary control unit 2 and branch controller 3 use main control unit 1's control signal as the standard, use driver's wish to give first place to, the security of car operation has been guaranteed.

In one embodiment, as shown in fig. 4, the sub controller 2 and the sub controller 3 further include a signal strength detection device 61, the signal strength detection device 61 is connected to a wireless receiving unit 82 of each vehicle door, a control signal of the key 6 is received by the wireless receiving unit 82, transmitted to the sub controller 2 and the sub controller 3 through the signal strength detection device 61, and transmitted to the main controller 1 through the wireless network by the sub controller 2 and the sub controller 3, and the main controller 1 determines the position of the key 6.

In some cases, the driver can leave the key 6 in the automobile, and most automobiles are provided with an automatic automobile locking device for a certain time after the automobile door is closed after flameout for safety, so that articles in the automobile can be prevented from being stolen.
