DETAILED DESCRIPTION

[0034] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0035] At present, multiple functions, such as door locks, window lifting, lights, wipers, etc., are usually managed through a regional controller located on the vehicle body. The regional controller is connected to different actuators through different connecting lines. However, the regional controller is far away from the multiple actuators at the door, and the regional controller needs to lead out multiple long connecting lines to the door to connect the multiple actuators at the door, which will result in a total length of all connecting lines in the wiring harness being longer and heavier. In order to solve the above problems, the embodiments of the present application provide a vehicle door and window control device, a control system and a vehicle. The above-mentioned vehicle door and window control device, control system and vehicle are described in detail below.

[0036] First, refer to Figures 1 to 3 The present application provides a vehicle door and window control device 1, which is arranged on a vehicle door 4 or a tailgate 5 in a vehicle. The vehicle door and window control device 1 includes a control module 101, which has a power interface, a communication interface and a plurality of functional interfaces. The power interface and the communication interface are both used to electrically connect to a regional controller 2 located on a vehicle body in the vehicle. The plurality of functional interfaces include a plurality of door functional interfaces and / or a plurality of tailgate functional interfaces; wherein the plurality of door functional interfaces are respectively used to electrically connect to a plurality of actuators 3 arranged on the vehicle door 4, and the plurality of tailgate functional interfaces are respectively used to electrically connect to a plurality of actuators 3 arranged on the tailgate 5. The plurality of door functional interfaces at least include a door lock and door handle functional interface, a window control functional interface and a light functional interface, and the plurality of tailgate functional interfaces at least include a rear wiper functional interface.

[0037] Among them, the vehicle door 4 usually refers to the door located on the side of the vehicle. The tailgate 5, which can also be called the back door, usually refers to the door located at the rear of the vehicle, which is used to open the trunk or rear storage space. The power interface in the control module 101 can be directly electrically connected to the regional controller 2 through a connecting line, and the regional controller 2 supplies power to the control module 101 through the connecting line and the power interface. The communication interface can be communicatively connected to the regional controller 2 through a two-way communication module 102 and a connecting line, and the communication interface can also be directly communicatively connected to the regional controller 2 through a connecting line. For the relevant instructions for controlling the vehicle door function and the tailgate function, the nearest regional controller 2 is issued to the control module 101 through the communication interface. After receiving the relevant instructions, the control module 101 sends a signal to the execution component 3 through the corresponding functional interface.

[0038] The vehicle door and window control device 1 also includes a housing and a circuit board, and the control module 101 is arranged on the circuit board. In one embodiment, the multiple functional interfaces only include multiple door functional interfaces. In another embodiment, the multiple functional interfaces only include multiple tailgate functional interfaces. For the vehicle door and window control device 1 arranged on the vehicle door 4, multiple door functional interfaces can be configured, and for the vehicle door and window control device 1 arranged on the tailgate 5, multiple tailgate functional interfaces can be configured. In this embodiment, the vehicle door and window control device 1 is a platform component, and different interfaces can be configured according to different installation positions of the vehicle door and window control device 1. The structure of the housing and the circuit board in the vehicle door and window control device 1 remains unchanged, that is, whether the vehicle door and window control device 1 is arranged on the vehicle door 4 or the tailgate 5, it can share a set of housing and circuit board, thereby reducing the cost of mold opening and circuit board design, and further reducing the development cost. In addition, for different functional requirements or different installation positions, it is only necessary to add or delete the corresponding functional interfaces in the control module 101, which can streamline the development strategy, shorten the development cycle, and can be flexibly applied to different scenarios.

[0039] In another embodiment, the multiple functional interfaces include both multiple door functional interfaces and multiple tailgate functional interfaces. In this case, the multiple functional interfaces correspond to the multiple actuators 3 provided on the door 4 and the tailgate 5, respectively. The vehicle door and window control device 1 can be provided on the door 4 or the tailgate 5. When the vehicle door and window control device 1 is provided on the door 4, the multiple tailgate functional interfaces corresponding to the multiple tailgate functions are not used. When the vehicle door and window control device 1 is provided on the tailgate 5, the multiple door functional interfaces corresponding to the multiple door functions are not used. In this embodiment, the vehicle door and window control device 1 can be used for both the door 4 and the tailgate 5 without adjustment.

[0040] The functional interface is specifically electrically connected to the actuator 3 via a connecting line. The door function interface is electrically connected to the actuator 3 provided on the door 4 via a connecting line, and the tailgate function interface is electrically connected to the actuator 3 provided on the tailgate 5 via a connecting line. The multiple door function interfaces may also include a rearview mirror function interface. The multiple tailgate function interfaces may also include a tailgate adjustment function interface and a tailgate buzzer function interface. The tailgate adjustment function may refer to functions such as unlocking the tailgate, opening and closing the tailgate, and adjusting the opening height.

[0041] The window control function interface may include a window lifting function interface and a window anti-pinch function interface, the light function interface may include at least a welcome light interface, and the light function interface may also include a turn signal interface, a blind spot indicator light interface, and an ambient light interface, the rearview mirror function interface may include a rearview mirror adjustment interface, a rearview mirror heating interface, and a rearview mirror folding interface. The door lock and door handle functions may include a door unlocking function and a door handle pop-up and retracting function, and the rearview mirror adjustment specifically refers to the adjustment of the position of the rearview mirror.

[0042] The actuator 3 is a component arranged on the vehicle door 4 or the tailgate 5 for executing the corresponding function. The actuator 3 may include a door lock and door handle function actuator 309 for executing the door lock and door handle function, a window control function actuator for executing the window control function, a light component for executing the light function, a rearview mirror actuator for executing the rearview mirror function, and a rear wiper assembly for executing the rear wiper function. The window control function actuator may include a window lifting actuator 307 and a window anti-pinch detection component 315, the rearview mirror actuator may include a rearview mirror adjustment actuator 301, a rearview mirror heating actuator 302, and a rearview mirror folding actuator 303, and the light component may include a welcome light 304, a turn signal 305, a blind spot indicator light 306, an ambient light 308, etc. The door lock and door handle function interface is used to electrically connect with the door lock and door handle function execution component 309, the window control function interface is used to electrically connect with the window control function execution component, the light function interface is used to electrically connect with the light component arranged on the corresponding vehicle door 4, the rearview mirror function interface is used to electrically connect with the rearview mirror execution component, and the rear wiper function interface is used to electrically connect with the rear wiper assembly 310.

[0043] In an existing door and window control method, the door and window controller itself has a low integration level and a single function, and is only used to control door unlocking, window lifting, etc. In the embodiment of the present application, at least the door lock and door handle function, window control function, and light function are integrated into the vehicle door and window control device 1 disposed on the vehicle door 4, and at least the rear wiper function is integrated into the vehicle door and window control device 1 disposed on the tailgate 5, which can improve the integration level of the vehicle door and window control device 1.

[0044] In another existing door and window control method, the door and window controller is cancelled, and the function of the door and window controller is incorporated into the regional controller. In the embodiment of the present application, the control module 101 in the vehicle door and window control device 1 is electrically connected to the regional controller 2 located on the vehicle body through the two interfaces of the power interface and the communication interface, that is, the connection between the vehicle door and window control device 1 and the regional controller 2 can be realized through two connecting lines, and the control module 101 set on the vehicle door 4 or the tailgate 5 is electrically connected to the multiple actuators 3 located on the vehicle door 4 or the tailgate 5 through multiple functional interfaces. The control module 101 drives the actuator 3 nearby and supplies power to the actuator 3, that is, the connection between the control module 101 and the multiple actuators 3 can be realized through multiple short connecting lines. Compared with the regional controller being connected to multiple actuators through multiple long connecting lines, the number of long connecting lines drawn from the regional controller 2 can be significantly reduced, thereby shortening the total length of all connecting lines in the wiring harness, reducing the weight of the wiring harness, and further reducing the wiring harness cost. For example, when there are 10 actuators at the vehicle door, the existing zone controller needs to lead out 10 long connecting lines to the 10 actuators at the vehicle door respectively. In this embodiment, the zone controller 2 only needs to lead out 2 long connecting lines to the vehicle door and window control device 1, and the vehicle door and window control device 1 leads out 10 short connecting lines to the 10 actuators 3, saving 8 long connecting lines from the vehicle door and window control device 1 to the zone controller 2.

[0045] In addition, the control module 101 drives the actuator 3 nearby and supplies power to the actuator 3, which can improve the reliability of the door function or tailgate function control compared to the regional controller connected to the actuator through a long connecting line. The regional controller is usually arranged below the main structural member in the vehicle body, and the regional controller is inconvenient to disassemble and repair. If the door and window controller is cancelled and the functions of the door and window controller are incorporated into the regional controller, then when the door and window function fails, the regional controller needs to be removed for maintenance, which is inconvenient. In this embodiment, when the door and window function fails, it is only necessary to remove the vehicle door and window control device 1 from the door 4 or the tailgate 5, which can improve the ease of maintenance.

[0046] In an optional embodiment of the present application, referring to Figure 2 The control module 101 includes a microcontroller unit 1011 and at least one driver chip electrically connected to the microcontroller unit 1011; the window control function interface includes a window lifting function interface and a window anti-pinch function interface, the power interface, the communication interface, and the window anti-pinch interface are all located on the microcontroller unit 1011, and the window lifting function interface, the door lock and door handle function interface, the light function interface, and the rear wiper function interface are all located on at least one driver chip.

[0047] Among them, the window lifting function interface is used to be electrically connected to the window lifting execution component 307, and the window anti-pinch function interface is used to be electrically connected to the window anti-pinch detection component 315. The micro-control unit 1011 can use a chip with lower computing power, and one of the functions of the micro-control unit 1011 is to process the anti-pinch algorithm of the window. The communication control and logic control of the relevant instructions of the door function and the tailgate function are implemented by the regional controller 2. In this embodiment, the computing power of the micro-control unit 1011 is relatively low, and the low computing power design of the micro-control unit 1011 can meet the basic requirements of the anti-pinch function. The cost of the driving chip is relatively low, which can reduce the manufacturing cost of the vehicle door and window control device 1; in addition, the functional interface on the driving chip and the functional interface on the micro-control unit 1011 are connected to different execution components 3, so that different execution components 3 connected to different chips can work independently, thereby improving reliability.

[0048] In an optional embodiment of the present application, referring to Figure 2 , a wireless charging module 312 is provided on at least one door 4, and the microcontroller unit 1011 has a wireless charging function interface, and the wireless charging function interface is used to electrically connect to the wireless charging module 312. Among them, the wireless charging module 312 is located on the inner side of the vehicle window, and the wireless charging module 312 can be arranged at a position close to the window lifting switch on the armrest of the door 4. The wireless charging module 312 can be arranged horizontally or inclined relative to the horizontal direction. In this embodiment, by setting the wireless charging module 312 on the door 4, it is convenient for users to wirelessly charge their mobile phones, thereby improving the user experience. In addition, by setting the wireless charging function interface on the microcontroller unit 1011, the wireless charging module 312 can be powered nearby.

[0049] The vehicle door 4 is divided into a front door and a rear door, and the wireless charging module 312 is preferably arranged on the rear door. At present, the wireless charging function of the front row of the vehicle is provided by the wireless charging module arranged on the center console, but when the rear row is full of three people, it is not convenient for the passengers sitting on the left and right sides of the rear row to charge their mobile phones. In this embodiment, the wireless charging module 312 is arranged on the rear door, so that the passengers sitting on the left and right sides of the rear row can charge their mobile phones wirelessly.

[0050] In other embodiments, a wired charging module may be provided on at least one vehicle door 4, and the micro control unit 1011 has a wired charging function interface, and the wired charging function interface is used to be electrically connected to the wired charging module.

[0051] In an optional embodiment of the present application, referring to Figure 3At least one driver chip has a power input interface, the micro control unit 1011 has a power output interface, and the power output interface of the micro control unit 1011 is electrically connected to the power input interface of the driver chip; the vehicle door and window control device 1 also includes a backup power supply, which is electrically connected to the power input interface of the driver chip. The backup power supply is used to power the driver chip when the connection between the micro control unit 1011 and the zone controller 2 is disconnected.

[0052] Among them, at least one driver chip includes a first driver chip 1012 and a second driver chip 1013, both of which have a power input interface, and the micro control unit 1011 is connected to the power input interface on the first driver chip 1012 and the second driver chip 1013 through two different power output interfaces.

[0053] The number of backup power supplies can be set according to actual needs, for example, it can be set to one, two, etc. When the number of backup power supplies is one, the backup power supply is preferably electrically connected to the power input interface of the first driver chip 1012. When the number of backup power supplies is two, the two backup power supplies can be connected to the power input interfaces on the first driver chip 1012 and the second driver chip 1013, respectively. The backup power supply can be a capacitor 103, and the capacitor 103 can be charged by the micro control unit 1011, or by a separately provided battery.

[0054] Under normal circumstances, the microcontroller unit 1011 supplies power to the driver chip through the power output interface. When the connection between the microcontroller unit 1011 and the regional controller 2 is disconnected, the backup power supply supplies power to the driver chip. The backup power supply is connected to the driver chip through a power supply connection line, and a switch element may be provided on the power supply connection line, and the switch element is connected to the microcontroller unit 1011, and the microcontroller unit 1011 controls the conduction and disconnection of the switch element. Under normal circumstances, the switch element is disconnected. When the connection between the microcontroller unit 1011 and the regional controller 2 is disconnected, the switch element is turned on, and the backup power supply supplies power to the driver chip through the power supply connection line. The switching device may include a MOS (Metal-Oxide-Semiconductor Field-Effect Transistor) tube, and the source and drain of the MOS tube may be connected to the backup power supply and the driver chip respectively, and the gate of the MOS tube may be connected to the microcontroller unit 1011.

[0055] The power supply of the vehicle door and window control device 1 is provided by the nearest regional controller 2. If a collision accident occurs during driving, and the regional controller 2 cuts off the power supply to the vehicle door and window control device 1, the door handle cannot be ejected, the door 4 cannot be opened, and the people in the car cannot escape. In this embodiment, for safety reasons, when designing the circuit of the vehicle door and window control device 1, a backup power supply is designed for the driver chip with the door lock and door handle function interface. After the main power supply of the vehicle door and window control device 1 is cut off, the backup power supply will be started to power the driver chip, thereby ensuring the normal ejection of the door handle and the normal unlocking of the door, thereby facilitating the escape of people.

[0057] Among them, the current detection circuit is used to detect the magnitude of the current in real time, and the current detection circuit is specifically used to detect whether the current is overcurrent. By setting the current detection circuit, the risk of failure caused by excessive current can be avoided. The tailgate buzzer function interface is used to be electrically connected to the tailgate buzzer 313. The near-field communication function interface is used to be electrically connected to the near-field two-way communication module 314. The near-field two-way communication module 314 can be used for non-inductive unlocking of the vehicle. When a user approaches the vehicle with a device with NFC function, the microcontroller unit 1011 establishes a communication connection with the device carried by the user through the near-field two-way communication module 314 and the near-field communication interface to automatically trigger the vehicle unlocking mechanism after confirming the user's identity.
