Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a CarPlay connection method, device, equipment, and storage medium. Background Technology

[0002] CarPlay is one of the car infotainment features. Before Apple released the R16 plugin, the Bonjour service was an essential part of the CarPlay connection process. However, the Bonjour service code was complex, making debugging and modification difficult for non-professionals. Therefore, Apple released the R16 plugin in 2021. This version completely abandoned Bonjour, replacing it with IAP sessions, significantly reducing the development and maintenance complexity of CarPlay.

[0003] While the R16 plugin supports the new connection method, this new method is only supported on iOS 14 and above. For in-vehicle infotainment systems, compatibility with various iOS versions is essential. Therefore, ensuring compatibility between the old and new connection methods and meeting Apple's certification requirements for connection performance will be a major challenge for CarPlay development on in-vehicle systems. Summary of the Invention

[0004] This application provides a CarPlay connection method, apparatus, device, and storage medium, which can be used to make CarPlay on the vehicle's infotainment system compatible with both new and old connection methods, without affecting CarPlay's connection performance. The technical solution is as follows:

[0005] On one hand, embodiments of this application provide a CarPlay connection method applied to an in-vehicle terminal, the method comprising:

[0006] Establish an IAP session with the target device; the target device is a device that supports CarPlay connectivity.

[0007] Determine whether the target device is in a pre-established device list;

[0008] In response to the target device not being in the device list, determine whether CarPlayAvailability is received within a set time period;

[0009] If CarPlayAvailability is received within a set time period, a CarPlay connection with the target device is established based on the IAP session;

[0010] If CarPlayAvailability is not received within a set time period, a CarPlay connection is established with the target device based on the pre-loaded Bonjour device discovery.

[0011] On the other hand, embodiments of this application provide a CarPlay connectivity device for use in an in-vehicle terminal, the device comprising:

[0012] The IAP session establishment module is used to establish an IAP session with the target device being accessed; the target device is a device that supports CarPlay connection.

[0013] The target device determination module is used to determine whether the target device is in a pre-established device list;

[0014] The CarPlayAvailability determination module is used to determine whether CarPlayAvailability is received within a set time period in response to the target device not being in the device list.

[0015] The first CarPlay connection establishment module is used to establish a CarPlay connection with the target device based on the IAP session when CarPlayAvailability is received within a set time period.

[0016] The second CarPlay connection establishment module is used to establish a CarPlay connection with the target device based on the pre-loaded Bonjour device discovery if CarPlayAvailability is not received within a set time period.

It is determined whether the target device is in a pre-established device list. If the target device is not in the device list, it is determined whether CarPlayAvailability is received within a set time period. If CarPlayAvailability is received within the set time period, a CarPlay connection is established with the target device based on the IAP session. If CarPlayAvailability is not received within the set time period, a CarPlay connection is established with the target device based on the pre-loaded Bonjour device discovery mechanism.

[0026] The embodiments of this application will now be described in further detail with reference to the accompanying drawings.

[0027] Please refer to Figure 1 The diagram illustrates a flowchart of a CarPlay connectivity method according to an embodiment of this application. This method can be applied to an in-vehicle terminal. The method may include the following steps:

[0028] Step 101: Establish an IAP session with the target device; the target device is a device that supports CarPlay connection.

[0029] The embodiment of the present application can be applied to a vehicle terminal, i.e., the execution subject is a vehicle terminal.

[0030] The embodiment of the present application can enable the vehicle terminal to support a CarPlay new connection mode and a CarPlay old connection mode, wherein,

[0031] The CarPlay new connection mode is that the Apple R16 plug-in supports a connection mode in which Bonjour interaction is changed to iap interaction, and no Bonjour is involved in the connection process.

[0032] The CarPlay old connection mode is that the plug-in before the Apple R16 supports a connection mode in which only Bonjour interaction is supported, and Bonjour is involved in the connection process.

[0033] The target device is an iOS system installed device supporting CarPlay connection, and in the present example, the target device can be an iOS system installed mobile phone, iPad, iPod and the like, and specifically, the specific type of the target device can be determined according to business requirements, which is not limited in the embodiment.

[0034] In a specific implementation, after the target device accesses the vehicle terminal, it can be first judged whether the device supports CarPlay connection, and if so, the master-slave switching operation is performed, and after the master-slave switching operation is completed, the process of establishing an Iap session connection is performed. The implementation process can be described in detail in combination with the following specific implementation mode.

[0035] In a specific implementation of the present application, before the above step 101, steps A1 and A2 can also be included.

[0036] Step A1: After detecting that the target device accesses, it is determined whether the target device supports CarPlay connection.

[0037] In the embodiment, the vehicle terminal can detect whether there is an access device by detecting the voltage signal at the device access interface.

[0038] After detecting that the target device accesses, it can be first judged whether the target device supports CarPlay connection, and specifically, the judgment mode can be that the vehicle terminal sends a CarPlay connection command to the target device, and obtains the response message of the target device, and through the response message, it can be judged whether the target device supports CarPlay connection.

[0039] After it is determined that the target device does not support CarPlay connection, subsequent operations are not required, and normal data transmission and reception can be performed.

[0040] After determining that the target device supports CarPlay connection, step A2 is performed.

[0041] Step A2: performing role switch operation on the target device in the case that it is determined that the target device supports CarPlay connection.

[0042] After determining that the target device supports CarPlay connection, role switch operation can be performed on the target device (i.e. role switch), and after the completion of the role switch, step 101 described above can be performed.

[0043] After the completion of the role switch, Iap session with the target device can be established.

[0044] After establishing the Iap session with the target device, step 102 is performed.

[0045] Step 102: determining whether the target device is in a pre-established device list.

[0046] The device list refers to a pre-established list for storing information of devices that do not support CarPlay connection through Iap session. In the present example, the USB serial number and / or Bluetooth address of the device that does not support CarPlay connection through Iap session is stored in the device list.

[0047] After establishing the Iap session with the target device, it can be further determined whether the target device is in the pre-established device list. Specifically, the USB serial number of the target device or the Bluetooth address of the target device can be acquired to determine whether the USB serial number of the target device or the Bluetooth address of the target device is in the device list. Specifically, the implementation process can be described in detail in combination with the specific implementation mode described below.

[0048] In a specific implementation mode of the present application, step 102 described above can include:

[0049] Sub-step B1: acquiring the USB serial number corresponding to the target device, and determining whether the target device is in the device list according to the USB serial number.

[0050] In the present embodiment, when the connection mode of the target device and the vehicle-mounted terminal is a wired connection mode, the USB serial number of the target device can be acquired, and whether the target device is in the device list can be determined according to the USB serial number of the target device. Specifically, it is queried in the device list whether there is a USB serial number identical to the USB serial number of the target device, and if there is, it indicates that the target device is in the device list. Otherwise, it indicates that the target device is not in the device list.

[0051] Sub-step B2: Obtain the Bluetooth address corresponding to the target device, and determine whether the target device is in the device list according to the Bluetooth address.

[0052] When the connection mode of the target device and the vehicle terminal is a wireless connection mode, the Bluetooth address of the target device can be obtained, and it is determined whether the target device is in the device list according to the Bluetooth address of the target device. Specifically, it is determined whether there is a Bluetooth address identical to the Bluetooth address of the target device in the device list. If there is, it indicates that the target device is in the device list. Otherwise, it indicates that the target device is not in the device list.

[0053] After it is determined that the target device is in the device list, the CarPlay connection with the target device can be established based on the Bonjour discovery device. Specifically, when it is determined that the target device is in the device list, the CarPlay connection with the target device can be established based on the Bonjour discovery device loaded in the vehicle terminal in advance, that is, the vehicle terminal waits for the notification of the Bonjour discovery device, and then calls the start interface of the Apple plug-in to initiate the CarPlay connection.

[0054] After it is determined that the target device is not in the device list, step 103 is performed.

[0055] Step 103: In response to the target device not being in the device list, it is determined whether CarPlayAvailability is received within a set time length.

[0056] The set time length refers to a time length set in advance for determining whether CarPlayAvailability is received. In the present example, the set time length can be 3s, etc. Specifically, the specific value of the set time length can be determined according to business requirements, and the present embodiment does not limit this.

[0057] After it is determined that the target device is not in the device list, it can be determined whether CarPlayAvailability is received within a set time length in response to the target device not being in the device list.

[0058] In a specific implementation, after it is determined that the target device is not in the device list, a timer can be started to start timing, and it is determined whether CarPlayAvailability is received within a time period from the start time of the timing to the set time length.

[0059] If CarPlayAvailability is received within the set time length, step 104 is performed.

[0060] If CarPlayAvailability is not received within the set time length, step 105 is performed.

[0061] In the case that CarPlayAvailability is received within the set time length, step 104 is performed to establish the CarPlay connection with the target device based on the Iap session.

[0062] In the case that CarPlayAvailability is received within the set time length, the CarPlay connection with the target device can be established based on the Iap session. Specifically, the start interface of the preset plug-in (i.e., the Apple plug-in) can be called, and the CarPlayStartSession notification message can be sent to the target device through the Iap session to establish the CarPlay connection with the target device. Specifically, after the CarPlayStartSession notification message is sent by the vehicle terminal to the target device, the CarPlay connection with the target device can be established after the target device responds to the CarPlayStartSession notification message.

[0063] In the case that CarPlayAvailability is not received within the set time length, step 105 is performed to establish the CarPlay connection with the target device based on the preloaded Bonjour discovery device.

[0064] In the case that CarPlayAvailability is not received within the set time length, the CarPlay connection with the target device can be established based on the preloaded Bonjour discovery device. Specifically, the vehicle terminal waits for the notification message sent by the Bonjour discovery device, and then, in response to the notification message, the start interface of the Apple plug-in can be called to send the CarPlay connection message to the target device to establish the CarPlay connection with the target device.

[0065] In this embodiment, after it is determined whether CarPlayAvailability is received within the set time length, the target device can also be added to the device list. The implementation process can be described in detail in combination with the specific implementation manners described below.

[0066] In one specific implementation manner of the present application, after step 103, the following step can also be included.

[0067] In the case that CarPlayAvailability is not received within the set time length, step C1 is performed to obtain the USB serial number or the Bluetooth address corresponding to the target device.

[0068] In the embodiment, in the case that the CarPlayAvailability is not received within the set time length, the USB serial number of the target device or the Bluetooth address of the target device can be acquired.

[0069] In a specific implementation, when the connection mode of the target device and the vehicle-mounted terminal is a wired connection mode, the USB serial number of the target device can be acquired.

[0070] When the connection mode of the target device and the vehicle-mounted terminal is a wireless connection mode, the Bluetooth address of the target device can be acquired.

[0071] After the USB serial number of the target device or the Bluetooth address of the target device is acquired, step C2 is performed.

[0072] Step C2: adding the USB serial number or the Bluetooth address to the device list.

[0073] After the USB serial number of the target device or the Bluetooth address of the target device is acquired, the USB serial number of the target device or the Bluetooth address of the target device can be added to the device list.

[0074] The embodiment of the application can accelerate the connection speed of the target device in the next connection by saving the devices supporting the old connection mode (i.e., the Bonjour discovery device connection mode) in the device list.

[0075] In actual application, the devices not supporting the new connection mode are saved in the device list to accelerate the connection of the devices by judging whether the devices support the new connection mode according to whether the devices notify the CarPlayAvailability. However, due to the complex timing sequence of the CarPlay connection, the timing sequence of the device connection and the device notifying the CarPlayAvailability cannot be guaranteed, and the state machine mode is used. The above scheme provided by the embodiment of the application can make the CarPlay of the vehicle-mounted terminal compatible with the new and old connection modes (i.e., the Iap session connection mode and the Bonjour discovery device connection mode) by judging which CarPlay connection mode is used to establish the CarPlay connection with the target device according to the defined timing sequence (i.e., the state machine mode), and does not affect the connection performance of the CarPlay.

[0076] The flow of the state switching in the state machine mode can be as shown in Figure 2

[0077] Referring to Figure 2 , a schematic diagram of the state switching of the CarPlay new and old connection state machine provided by an embodiment of the application is shown. As shown in Figure 2 ​As shown, the initial state is Idle. Upon receiving a device connection signal, it switches to a double-checked state. When entering the double-checked state, it checks if the currently connected device has already sent a CarPlayAvailability signal. If so, it switches to the new connection state. Otherwise, it checks if the currently connected device already exists in the local device list. If it does, it switches to the old connection state; otherwise, it starts a 3-second timer. After entering the double-checked state, if a CarPlayAvailability signal is received from the device, it switches to the new connection state. If no CarPlayAvailability signal is received after the 3-second timeout, it switches back to the old connection state.

[0078] After entering the old connection state, wait for Bonjour's device discovery notification. If a notification is received, call the Apple plugin's start interface to initiate a connection.

[0079] After entering a new connection state, you can call the start interface of the Apple plugin and send a CarPlayStartSession notification to the device through the IAP session to initiate the connection.

[0080] The implementation process of solving the compatibility problem of old and new CarPlay connection methods on the vehicle terminal by combining the state machine pattern of the device list provided in this embodiment can be combined with... Figure 3 The following is a detailed description.

[0081] Reference Figure 3 This is a schematic diagram of the wired CarPlay connection timing provided in one embodiment of this application.

[0082] like Figure 3 As shown, the first stage is as follows: 1.1. The iOS device connects to the vehicle terminal; 1.2. Check if the iOS device supports CarPlay(); 1.3. If the iOS device supports CarPlay(), establish an IAP session with the iOS device; 1.4. Check if the iOS device is in the local device list.

[0083] The second stage: If the iOS device is in the local device list, the connection to the iOS device can be established by calling the start interface of the Apple CarPlay plugin based on Bonjour to discover the device.

[0084] Third stage: If the iOS device is not in the local device list, start the 3s (i.e., the set duration in this example) timer.

[0085] The fourth stage: receiving the CarPlayAvailability before the timer out, informing the CarPlayAvailability, and then establishing the CarPlay connection with the iOS device based on the Iap session, specifically, sending the CarPlayStartSession notification message to the iOS device, and then establishing the CarPlay connection with the iOS device after the iOS device responds to the CarPlayStartSession notification message. Thus, the CarPlay session establishment is completed.

[0086] The fifth stage: detecting the iOS device connection after not receiving the CarPlayAvailability before the timer out, and then establishing the CarPlay connection with the iOS device based on the Bonjour discovery device. Specifically, waiting for the notification message sent by the Bonjour discovery device, and then sending the CarPlay connection message to the iOS device to establish the CarPlay connection with the iOS device by calling the start interface of the Apple plug-in in response to the notification message. Meanwhile, the iOS device is saved to the local device list, and thus the CarPlay session establishment is completed.

[0087] Experiments show that the CarPlay connection method provided in the embodiments of the present application can determine whether the target device is in the pre-established device list by establishing an Iap session with the accessed target device, which is a device supporting the CarPlay connection, and determine whether the CarPlayAvailability is received within a set time period in response to the target device not being in the device list. In the case that the CarPlayAvailability is received within the set time period, the CarPlay connection with the target device is established based on the Iap session. In the case that the CarPlayAvailability is not received within the set time period, the CarPlay connection with the target device is established based on the pre-loaded Bonjour discovery device. The embodiments of the present application can achieve the purpose of making the CarPlay of the vehicle terminal compatible with the new and old connection methods while not affecting the connection performance of the CarPlay by combining the pre-established device list and the state machine mode (i.e., the defined device connection and device notification CarPlayAvailability timing).
