[0027] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0028] The following describes the access device and vehicle of the smart cockpit expandable device proposed in the embodiments of the present application with reference to the accompanying drawings.

[0029] Figure 1 This is a connection diagram of an access device for a smart cockpit expansion device according to an embodiment of the present application.

[0030] Combination Figure 1-Figure 5 As shown, the access device 100 of the smart cockpit expandable device in the embodiment of the present application includes an external device adaptation module 10, a device expansion component module 20, a device expansion service module 30 and an HMI application interface module 40 connected in sequence.

[0031] Among them, the external device adapter module 10 is provided with at least one type of adapter unit, which is used to connect to the external device through at least one type of adapter unit, wherein the type of the adapter unit corresponds to the interface type of the external device. The HMI application interface module 40 is used to connect to the HMI application interface of the smart cockpit. The device extension component module 20 is used to perform unified communication processing on the data information provided by the external device and / or the data information provided by the HMI application of the smart cockpit, so as to establish communication between the external device and the HIM application of the smart cockpit. The device extension service module 30 is used to concretize and divide the functions provided by the external device to establish a mapping relationship between the functions provided by the external device and the service functions provided by the smart cockpit, so as to call the external device based on the mapping relationship, and the HMI application interface module 40 performs interface settings based on the service functions provided by the smart cockpit.

[0032] Specifically, the external device may include a network device, a USB device, a serial port device, etc., for the functional expansion of the smart cockpit. The external device adapter module 10 may determine an adapter unit according to the interface type of the connected external device, and is used to establish a wired connection or a wireless connection with the external device. For example, the external device adapter module 10 is integrated with an external device interface driver adapter unit such as UART, USB, Bluetooth, WIFI, etc., to support a variety of access methods for external devices.

[0033] The device extension component module 20 can solve the problem of various data interaction forms and inconsistent communication protocols encountered by external devices after connecting to the cockpit by integrating various functional modules required for the operation of the expansion device, i.e., the external device in the cockpit system, such as device communication, data security, network management and other modules. For example, the device extension component module 20 can convert the control command sent by the smart cockpit into a communication protocol to convert the control command that conforms to the communication protocol corresponding to the external device, and then issue the control command after the communication protocol conversion; or, the device extension component module 20 can convert the device information sent by the external device into a communication protocol to convert the device information that conforms to the communication protocol corresponding to the smart cockpit, and then upload the device information after the communication protocol conversion; or, a unified intermediate communication protocol is provided in the device extension component module 20, and the control command sent by the smart cockpit and the device information sent by the external device are converted into the intermediate communication protocol for communication, and there is no specific limitation. In addition to the unification of the communication protocol, the device extension component module 20 can also be used for data format conversion, data encryption and decryption, etc., to achieve normal communication between the external device and the HIM application of the smart cockpit.

[0034] The device extension service module 30 concretizes the functions provided by the external device into service functions that can be provided to the user, and provides the basis for the implementation of the HMI application interface. For example, the functions provided by the external device are divided into IOT services, in-vehicle devices, environmental health and remote devices.

[0035] The HIM application interface module 40 is used to connect to the HMI application of the smart cockpit and is provided with an interface corresponding to the service functions that the smart cockpit can provide. During the application process, when the HIM application calls the interface of the HIM application interface module 40 and determines that the service function called by the HIM application is environmental health, the device extension service module 30 determines the external device corresponding to environmental health, and then calls the target external device through the device extension component module 20 and the external device adapter module 10.

[0036] After the HMI application of the smart cockpit is connected to the HMI application interface module 40 and the external device is connected to the device extension service module 10, the HMI application of the smart cockpit can directly obtain the device information of the external device through the access device 100 of the smart cockpit expandable device, and send control commands to the external device through the HMI application interface module 40, or incorporate the external device into the scene management of the cockpit, and the HMI application provides scene management to the user, which facilitates the application development of the smart cockpit.

[0037] This embodiment proposes a unified integrated access device for smart cockpit accessible devices, which supports various access methods for external devices and unifies differentiated communication protocols within the device to achieve normal communication between the smart cockpit and external devices, facilitates the functional expansion of cockpit equipment, and reduces the development complexity of cockpit systems and applications.

[0038] In one embodiment of the present application, the device extension service module 30 is also used to, when receiving a control command issued by an HMI application through the HMI application interface module 40, determine a target service function based on an interface in the HMI application interface module 40 called by the HMI application, and determine a target external device according to the target service function and a mapping relationship, so as to send the control command to the target external device through the device extension component module 20 and the external device adaptation module 10.

[0039] In one embodiment of the present application, the service functions provided by the smart cockpit include IOT services, in-vehicle equipment, environmental health, and remote equipment.

[0040] Specifically, when the HMI application of the smart cockpit needs to perform operations such as device information query or device control on the external device, the HMI application directly calls the corresponding interface in the HMI application interface module 40 based on the target demand, and sends the corresponding control command to the device extension service module 30 through the interface. The device extension service module 30 determines the target service function based on the interface called by the control command, and thus determines the target external device in combination with the pre-established mapping relationship between the function provided by the external device and the service function provided by the smart cockpit, and then sends the control command to the target external device through the device extension component module 20 and the external device adapter module 10.

[0041] For example, a communication path corresponding to each external device is established through the device extension component module 20 and the external device adapter module 10. After the device extension service module 30 determines the target external device, it can issue a control command through the communication path through which the target external device passes. It is also possible to pre-store the ID addresses corresponding to each external device. After the device extension service module 30 determines the target external device, the control command and the ID address of the target external device are packaged and sent to the device extension component module 20. The device extension component module 20 performs communication protocol conversion on the control command based on the ID address of the target external device, and sends the converted control command and the ID address of the target external device to the external device adapter module 10. The external device adapter module 10 sends the control command to the target external device based on the ID address of the target external device.

[0042] In one embodiment of the present application, the device extension component module 20 includes: a communication protocol adapter unit for serializing control commands; a network management module for giving the serialized control commands to an external device adapter module, so as to send the control commands to the target external device through the external device adapter module.

[0043] That is, the device extension service module 30 connects the functions based on the interface call with the services provided by the external device, and after the control command is serialized into the system standard protocol in the device extension component module 20, it is sent to the external device adapter module 10 through the network transmission module.

[0044] In one embodiment of the present application, the external device adaptation module 10 is further configured to perform a deserialization operation on the received control command to obtain a device operation instruction, so as to control the target external device based on the device operation instruction.

[0045] That is, the external device adapter module 10 is also used to parse the system standard protocol, deserialize the received control command into a device operation instruction, and complete the control operation of the target external device through the corresponding external device driver, ie, the adapter unit.

[0046] In one embodiment of the present application, the device extension component module 20 further includes: a data security unit for performing encryption and decryption operations on data information.

[0047] That is to say, the network management, data encryption, protocol adaptation and other modules provided by the device extension component module 20 unify the communication format and interaction protocol of the connected external devices, and the device extension service module 30 provides the access device service function to the upper layer. In addition, the device extension component module 20 can also include a device control unit, a configuration management unit, a device management unit, etc., and the module application can be carried out according to the actual situation.

[0048] In one embodiment of the present application, the external device adaptation module 10 includes: a wired adaptation unit for establishing a wired connection with the external device; and a wireless adaptation unit for establishing a wireless connection with the external device.

[0049] For example, the wired adapter unit includes one or more of a UART unit, a USB unit, and an I2C unit, and is connected to a local device through the wired adapter unit. The wireless adapter unit includes one or more of a Bluetooth unit, a WIFI unit, and a 4G / 5G unit, and is connected to a remote device through a wireless adapter unit. Therefore, the external device adapter module 10 in this embodiment can adapt the access interface of the external device through the wireless adapter unit and the wireless adapter unit, so that it can be normally connected to the smart cockpit system.

[0050] In one embodiment of the present application, the HMI application interface module 40 includes: an information receiving unit, used to receive data information sent by the external device and forward the data information to the smart cockpit; a device management unit, used to receive a control command for hair washing of the smart cockpit, and forward the control command to the device extension service module, so as to send the control command to the target external device through the device extension service module, the device extension component module and the external device adapter module; a scene management unit, used to incorporate the external device into the scene management of the smart cockpit, so that the HMI application of the smart cockpit provides scene management to the user based on the external device.

[0051] Specifically, after the HMI application of the smart cockpit is connected to the HMI application interface module 40, the device information of the external device can be directly obtained through the information receiving unit, and the control command can be sent to the external device through the device management interface. The external device can be included in the cockpit scene management through the scene management interface, and the HMI application provides scene management to the user. As a result, the HMI application interface module 40 unifies the interfaces such as external device operation, device information acquisition, and cockpit scene in the cockpit application, which facilitates the development of cockpit applications. Among them, the device interface includes a device control port, a data display port, an account management port, and a device management port, and the scene interface includes a scene acquisition port, a scene execution port, a scene creation port, and a scene management port.

[0052] As a specific embodiment of the present application, the architecture of the access device of the smart cockpit expandable device is as follows: Figure 1-5 As shown, the steps of obtaining the information of the external device through the HMI application interface module 40 in the cockpit HMI application are as follows Figure 6 When the user needs to query the device information, control the device, etc. in the cockpit HMI application, the HMI application can directly call the interface provided by the HMI application interface module provided by the device, as shown in the figure. Figure 7 shown.

[0053] This embodiment proposes a unified integrated access device for smart cockpit accessible devices. The device supports various access methods for external devices, unifies differentiated communication protocols within the device, integrates network connection, data security and other modules required for the operation of external devices, and opens unified device function operation, data display and other interfaces to the HMI application layer of the smart cockpit system, reducing the development work of cockpit applications.

[0054] In summary, according to the access device of the smart cockpit expandable device of the embodiment of the present application, it includes an external device adaptation module, a device extension component module, a device extension service module and an HMI application interface module connected in sequence. The external device adaptation module is provided with at least one type of adaptation unit to facilitate connection with the external device through at least one type of adaptation unit, wherein the type of the adaptation unit corresponds to the interface type of the external device, and is connected to the HMI application interface of the smart cockpit through the HMI application interface module.
