Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.

[0024] First, the application scenarios to which the present application is applicable are introduced. The present application can be applied in the field of vehicle-mounted device communication technology.

[0025] Research has found that with the development of automotive technology, the demand for interaction between vehicle-mounted devices and wearable devices is becoming increasingly rich. ARHUD (augmented reality hud) has changed customers' perception of traditional displays. The current ARHUD is limited to the vehicle-mounted domain controller displaying the relevant information of the smart cockpit and intelligent driving through ARHUD through wired transmission. In special driving scenarios, the use of wired ARHUD display between motorcycles and riders will bring instability to driving, greatly affect the driving experience and increase driving risks.

[0026] Based on this, the embodiments of the present application provide a wireless communication method, device, equipment and medium, which can solve the problem in the prior art that the use of wired ARHUD display between the motorcycle and the rider will bring instability to driving, greatly affect the driving experience and increase driving risks through wireless communication between the vehicle-mounted domain controller and the ARHUD, thereby achieving the effect of enhancing the driving experience and reducing driving risks.

[0027] See also Figure 1 , Figure 1 A flow chart of a wireless communication method provided in an embodiment of the present application. Figure 1 As shown in , the wireless communication method provided by the embodiment of the present application includes:

[0028] S101. Send a handshake signal between the vehicle-mounted domain controller and the ARHUD.

[0029] The vehicle-mounted domain controller and ARHUD are wirelessly connected via BT / WIFI.

[0030] Among them, the on-board domain controller BT adopts 5.0 communication protocol to support 24M communication rate, and WIFI adopts wifi6 communication protocol to support 9.6Gbps communication rate.

[0031] S102: After the handshake is successful, control the transmission of various target data between the vehicle-mounted domain controller and the ARHUD at preset intervals.

[0032] The multiple target data include heartbeat data, verification data, control instruction data and reset data.

[0033] S103. For a type of target data, if there is an abnormality in the data transmission between the vehicle-mounted domain controller and the ARHUD, the target data is retransmitted or the data transmission abnormality is determined according to a pre-set abnormality handling method for the type of target data.

[0034] Among them, if the heartbeat data transmission between the vehicle-mounted domain controller and ARHUD is abnormal, the following steps are performed according to the pre-set heartbeat data exception handling method: If the heartbeat data transmission between the vehicle-mounted domain controller and ARHUD is abnormal, the heartbeat data between the vehicle-mounted domain controller and ARHUD continues to be monitored; if the vehicle-mounted domain controller and ARHUD still cannot receive heartbeat data after a continuous preset time, it is determined that the communication between the vehicle-mounted domain controller and ARHUD is abnormal.

[0035] Optionally, the method further includes: when it is determined that the communication between the vehicle-mounted domain controller and the ARHUD is abnormal, controlling the vehicle-mounted domain controller to send reset data to the ARHUD; and the ARHUD performs a reset operation in response to the reset data.

[0036] The control instruction data includes configuration data or refresh instructions.

[0037] Optionally, the method further includes: controlling the vehicle-mounted domain controller to send configuration data or a refresh instruction to the ARHUD, so that the ARHUD performs configuration update or refresh according to the configuration data or the refresh instruction.

[0038] Wherein, the verification data includes a video data verification value.

[0039] The method further includes: controlling the vehicle-mounted domain controller to obtain a video data verification value fed back by the ARHUD each time a frame of data is sent to the ARHUD; determining whether there is an abnormality in the video data verification value fed back by the ARHUD; if there is an abnormality in the video data verification value fed back by the ARHUD, determining that the frame of data received by the ARHUD is erroneous, and sending the frame of video data again before the next frame interrupt request signal is interrupted.

[0040] Optionally, the method further includes: if there is no abnormality in the video verification data fed back by the ARHUD, determining that the video data information output by the vehicle-mounted domain controller is successfully output to the ARHUD.

[0041] For example, take the example of the vehicle-mounted domain controller initiating a WIFI connection to ARHUD: the vehicle-mounted domain controller actively initiates a pairing connection request to ARHUD as a client; the vehicle-mounted domain controller determines whether the active connection is successful. If the connection is successful, then according to the WPA authentication process of WIFI access protection, the vehicle-mounted domain controller sends an authentication request to ARHUD, requesting ARHUD to authenticate its identity; ARHUD sends a plaintext challenge frame to the vehicle-mounted domain controller; the vehicle-mounted domain controller encrypts the challenge with the WEP shared key and returns the encrypted data to ARHUD; ARHUD decrypts the frame and sends an authentication response.

[0042] Otherwise, end the current network connection process.

[0043] Determine whether the vehicle domain controller and ARHUD are authenticated successfully. If they are authenticated by the other party, determine whether there is data to be sent, and if so, send data.

[0044] Otherwise, it means that some communication devices may be illegal, and the current network connection process ends.

[0045] If there is data to be sent, the on-board domain controller encapsulates the data to be sent according to the data message format of Table 1, and then encrypts the encapsulated data according to the public key in the digital certificate stored in itself and sends it;

[0046] If there is no data to be sent, determine whether there is data to be received. If data needs to be received, the vehicle domain controller decrypts the received data according to the public key in the digital certificate stored in itself, and then analyzes the received data, parses out the message type in the data, and performs corresponding processing according to the message type. For example: if the message type is parsed to be a firewall linkage configuration file, the file is saved, etc.

[0047] Otherwise, end the current network connection process.

[0048] Among them, a unified communication protocol is used to complete various functions between devices, that is, the data transmitted between devices adopts a unified data encapsulation format (Type Seq_num Length Data), where Type indicates the type of data packet, Seq_num indicates the sequence number of the data packet, Length indicates the length of the data packet, and Date is the content of the data packet.

[0049] Among them, Type occupies two bytes, and the types include: frame exception information, system status information, upgrade package data, start / stop, video stream data, etc.

[0055] The exception handling module 203 is used for retransmitting a type of target data or determining the data transmission exception according to a preset exception handling method for the target data if there is an exception in the data transmission between the vehicle-mounted domain controller and the ARHUD.

[0056] The multiple target data include heartbeat data, verification data, control instruction data and reset data.
