The controller realizes the boost function. At the same time, the controller has an adjustable output voltage to meet the power requirements of different loads. Through the communication bus, the controller receives the vehicle controller signal to start and close the glass dimming function and intelligently adjust it. The control of multiple channels is realized through the hardware circuit design of the controller, so as to control the PDLC color-changing glass of the window to display patterns of different transparency.

[0060] On the one hand, the present invention provides a window welcoming and seeing-off control system based on automobile glass, referring to Figure 1, shows a schematic diagram of a car window welcoming and seeing-off control system based on car glass in accordance with the present invention. The car window welcoming and seeing-off control system based on car glass includes: an intelligent entry control system 4, a vehicle host 3, a car window multi-channel color change control module 2 and a car window color change glass 1.

[0061] The smart entry control system 4 is used to monitor the distance between the smart key 6 and the vehicle and generate a display function control signal and send the display function control signal to the vehicle host 3 .

[0062] The vehicle-mounted host 3 includes a storage module and is communicatively connected to the vehicle window multi-channel color change control module 2. The vehicle-mounted host 3 is used to receive the current key ID sent by the smart key 6, and when receiving the display function control signal, determines the window pattern control information based on the received current key ID and the correspondence between the key ID and the window pattern control information pre-stored in the storage module, and sends the window pattern control information to the vehicle window multi-channel color change control module 2.

[0063] The multi-channel window color-changing control module 2 is connected to the V-bat voltage terminal and the ground terminal; the multi-channel window color-changing control module 2 is also connected to the window color-changing glass 1. The multi-channel window color-changing control module 2 is used to control the window color-changing glass 1 to display welcoming and seeing-off patterns according to the window pattern control information sent by the vehicle-mounted host 3. In this embodiment, the window color-changing glass 1 is PDLC window glass. PDLC (Polymer Dispersed Liquid Crystal) window glass: A layer of liquid crystal dimming film (including PDLC) is installed between the glass. When power is turned on, the polymer liquid crystal material in the liquid crystal film is arranged in order, and the glass becomes transparent. On the contrary, it presents a translucent but opaque appearance. Different transparencies can be displayed in different color-changing areas of the PDLC window glass by dimming, showing, for example Figure 4 or Figure 5 The welcoming pattern or farewell pattern displayed in the

[0064] This solution is equipped with a vehicle window photochromic glass 1 with several color-changing areas. The transparency of different color-changing areas in the vehicle window photochromic glass 1 is controlled by the vehicle window multi-channel color-changing control module 2 to change the display pattern, thereby realizing the visual welcoming and seeing-off functions on the vehicle window when the user approaches or moves away. This not only improves the convenience and comfort of driving, but also greatly enhances the fun and experience of driving.

[0065] During the initial setting and use, when the smart key 6 is connected to the control system, the smart key 6 sends the key ID currently in use to the vehicle host 3; the smart key 6 operates the vehicle host 3 to set and save the window pattern control information. The vehicle host 3 binds the set window pattern control information with the key ID, and the vehicle host 3 sends the binding relationship and the window pattern control information to the window multi-channel color change control module 2 through CANBUS and records them in the EEPROM (storage module) of the vehicle host 3 at the same time; the window multi-channel color change control module 2 sets the light transmittance of the color change glass according to the window pattern control information sent by the vehicle host 3, and displays the welcoming or seeing-off pattern.

[0066] When used again, when the smart entry control system 4 monitors the distance between the smart key 6 and the vehicle and generates a display function control signal and sends the display function control signal to the vehicle-mounted host 3, the smart key 6 is connected to the control system, and the smart key 6 system sends the current key ID being used at this time to the vehicle-mounted host 3; the vehicle-mounted host 3 judges the received key ID and sends the corresponding window pattern control information to the window multi-channel color change control module 2 through CANBUS according to the window pattern control information and binding relationship stored in the EEPROM (storage module); the window multi-channel color change control module 2 sets the transmittance of the color-changing glass according to the window pattern control information sent by the vehicle-mounted host 3, and displays or changes the welcoming and seeing-off patterns.

[0067] In some optional solutions, the car window welcoming and seeing-off control system based on automobile glass further includes: a plurality of hard lines Hard line 1, Hard line 2…Hard line 7…, COM and a gateway 5 of the CAN bus. The intelligent entry control system 4 is connected to the vehicle host 3 via the CAN bus (CAN BUS); the vehicle window multi-channel color change control module 2 is connected to the corresponding color change area of ​​the color change glass via hard lines Hard line respectively; the gateway 5 is connected to the vehicle host 3 and the vehicle window multi-channel color change control module 2 via the CAN bus and LIN BUS respectively, so as to realize the signal conversion and transmission between the vehicle host 3 and the vehicle window multi-channel color change control module 2.

[0068] In a further embodiment, the vehicle window color changing glass 1 includes a plurality of color changing areas; the vehicle window multi-channel color changing control module 2 connects the color changing areas corresponding to the color changing glass through a plurality of channels (i.e., hard lines Hard line 1, Hard line 2... Hard line 7...), and controls the transparency of a color changing area through each channel; the vehicle window control parameter information includes a plurality of channel control parameter signals having a different phase difference from the COM channel; the vehicle window multi-channel color changing control module 2 controls the corresponding color changing areas through a plurality of channel control parameter signals, so as to display welcoming and seeing-off patterns on the vehicle window color changing glass 1. In this embodiment, the specific settings of the color changing areas and the welcoming and seeing-off patterns are as follows: Figure 4 and with Figure 5 As shown, each character on the welcome pattern corresponds to a channel 111, 7 characters correspond to 7 channels 111, plus 1 channel corresponding to the background part other than the characters on the glass, there are 8 channels 111 on this PDLC window glass, and each channel 111 transmits a channel control parameter signal and realizes display pattern control through a hard line. For details, refer to Figure 4 When the welcome pattern needs to be displayed, the seven character channels 111 are powered off, and the character area is in a non-transparent state; one background channel is powered on, and the background glass is transparent; by different channels 111 being non-transparent and transparent, the welcome pattern can be displayed on the car window glass. When the welcome pattern does not need to be displayed, all channels 111 can be powered on or off at the same time to make the entire car window display transparent or opaque. Similarly, the farewell pattern can be displayed on the car window, see Figure 5 .

[0069] The solution of the present invention breaks through the solution in the prior art that is limited to the controller and cannot adjust the boost circuit of the controller. The present application realizes multi-channel control by adjusting the phase difference between a single channel and the COM common channel; it breaks through the difficulty of controlling different changes in the output voltage levels of multiple channels, thereby realizing multi-channel control of the car window glass and displaying a farewell pattern on the car window.

[0070] See also Figure 3 In a further specific solution, the display function control signal generated by the smart entry control system includes: a welcome display control signal and a send-off display control signal. When it is detected that a user carries the smart key 6 into the welcome area of ​​the vehicle, a welcome display control signal is generated; when it is detected that a user carries the smart key 6 out of the vehicle lock area, a send-off display control signal is generated to turn on the send-off display function; the window control parameters generated by the vehicle host include a first window control parameter for controlling the display of a welcome pattern on the window color glass 1 and a second window control parameter for displaying a send-off pattern.

[0071] Optionally, when receiving the welcome display control signal, the vehicle-mounted host 3 determines the first window pattern control information and sends it to the window multi-way color change control module 2 based on the correspondence between the received current key ID and the key ID and window pattern control information pre-stored in the storage module (including the first window control parameter for displaying the welcome pattern and the second window control parameter for displaying the send-off pattern); the window multi-way color change control module 2 controls the display of the welcome pattern on the window color change glass 1 based on the first window pattern control information sent by the vehicle-mounted host 3. Correspondingly, when the vehicle-mounted host 3 receives the welcome guest display control signal, it determines the second window pattern control information and sends it to the window multi-way color change control module 2 based on the correspondence between the received current key ID and the key ID and window pattern control information pre-stored in the storage module (including the first window control parameter for displaying the welcome pattern and the second window control parameter for displaying the welcome guest pattern); the window multi-way color change control module 2 is used to control the display of the welcome guest pattern of the window color change glass 1 according to the second window pattern control information sent by the vehicle-mounted host 3.

[0072] See also Figure 2 The present invention also provides a method for controlling a window for welcoming or seeing off guests based on the color change of automobile glass, comprising the following steps:

[0073] S1: Monitor the distance between the smart key 6 and the vehicle and generate a display function control signal, and obtain the current key ID sent by the smart key.

The display function control signal includes: a welcome display control signal and a send-off display control signal. The window control parameters include a first window control parameter for controlling the window color glass 1 to display a welcome pattern and a second window control parameter for displaying a send-off pattern.

[0075] The step of determining the window pattern control information includes: when receiving the welcome display control signal, according to the correspondence between the received current key ID and the key ID and the window pattern control information pre-stored in the storage module, determining the first window pattern control information and sending it to the window multi-channel color change control module 2; according to the first window pattern control information sent by the vehicle host 3, controlling the display of the welcome pattern of the window color change glass 1. Similarly, when receiving the send-off display control signal, according to the correspondence between the received current key ID and the key ID and the window pattern control information pre-stored in the storage module, determining the second window pattern control information and sending it to the window multi-channel color change control module 2; according to the second window pattern control information sent by the vehicle host 3, controlling the display of the send-off pattern of the window color change glass 1.

[0076] S3: According to the window pattern control information, the window color changing glass 1 is controlled to display the welcoming and seeing-off patterns.

[0077] Specifically, according to the first window pattern control information sent by the vehicle host 3, the vehicle window tinted glass 1 is controlled to display a welcome pattern; or according to the second window pattern control information sent by the vehicle host 3, the vehicle window tinted glass 1 is controlled to display a send-off pattern. In this embodiment, the first window pattern control information and the second window pattern control information both include a plurality of channel control parameter signals. The step of controlling the vehicle window tinted glass 1 to display a welcome or send-off pattern specifically includes: according to a plurality of channel control parameter signals, controlling the color change area corresponding to the vehicle window tinted glass 1 to change color (for example, change transparency) so as to display the welcome or send-off pattern on the vehicle window tinted glass 1.

[0078] In one example, the control method for welcoming and seeing off guests based on the color change of automobile glass specifically includes:

[0079] See also Figure 1 and Figure 3When a user approaches the vehicle with a valid smart key (UID) 6, at a distance of 4 meters (configurable) from the vehicle, the in-vehicle sensor (such as a low-frequency antenna or a Bluetooth sensor) in the smart entry control system 4 (SCA) will sense the presence of the owner and send a welcome display control signal to the vehicle host 3 (IVI) through the CAN BUS; the vehicle host 3 determines the received current key ID, and determines the welcome display control signal according to the first window pattern control information stored in the EEPROM (storage module) and the binding relationship with the key ID. The welcome display control signal is converted by the GW gateway 5 and sent to the window multi-channel color change control module 2 (SIG ECU) through LIN; the window multi-channel color change control module 2 (SIG ECU) sets the transmittance of the corresponding color change area in the color change glass according to the welcome display control signal sent by the vehicle host 3 through the control of multiple channels (Hard line 1, Hard line 2...Hard line 7...Hard line 8.) of the hardware circuit, thereby displaying "Welcome" on the color change glass, such as Figure 4 As shown; when entering the vehicle unlocking area, an unlocking command is sent to the control unit in the vehicle to unlock the door. Figure 1 and Figure 3 When the user leaves the vehicle with the smart key 6 (UID), at a distance of 3 meters (configurable) from the vehicle, the in-vehicle sensor in the smart entry control system 4 (SCA) will sense the departure of the owner and generate a send-off display control signal, and send it to the vehicle host 3 through the CAN BUS; the vehicle host 3 sends a lock command to the in-vehicle control unit according to the received send-off display control signal, and the vehicle host 3 (IVI) will determine the binding relationship between the received key ID and the second window pattern control information. If it is determined that the binding relationship is met, the window pattern control information corresponding to the current key ID stored in the EEPROM (storage module) is converted into a LIN signal through the CAN bus and the GW gateway 5, and then sent to the window multi-channel color change control module 2; the window multi-channel color change control module 2 (SIG ECU) sets the transmittance of the color change glass according to the second window pattern control information sent by the vehicle host 3 through the control of multiple channels (Hard line 1, Hard line 2...Hard line 7...Hard line 8.) of the hardware circuit, so as to display the send-off pattern "See You" on the window, such as Figure 5 shown.

[0080] In the scheme of the present invention, the vehicle window photochromic glass is designed into multiple channels according to the patterns to be displayed. The power on and off of the multiple channels are controlled by the vehicle window multi-channel photochromic control module SIG, so that different patterns can be displayed in each color-changing area of ​​the vehicle window photochromic glass. That is, the vehicle window photochromic glass itself can display different patterns, with a simple structure and low cost. It not only improves the convenience and comfort of driving, but also greatly enhances the driving pleasure and experience.
