Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0024] In the existing technology, most head-up displays (HUDs) reverse-parse the diagnostic CAN messages provided by the OBD interface to obtain vehicle information. Therefore, there are differences in the message format area of ​​the diagnostic CAN messages corresponding to OBD under different car manufacturers and different models. On the one hand, from the perspective of the implementation cost of the head-up display (HUD), in the process of the head-up display (HUD) obtaining and displaying vehicle information, separate diagnostic CAN message parsing chips need to be pre-installed for different car manufacturers and different models, which increases the implementation cost of the head-up display (HUD). On the other hand, from the perspective of the display content of the head-up display (HUD), the vehicle information obtained by the existing technology from the diagnostic CAN messages provided by the OBD interface is relatively simple, generally some basic vehicle operation information, such as the current vehicle speed and the current gear of the vehicle, etc., and cannot support the display of information such as navigation and multimedia, that is, the range of displayed data is limited.

[0025] Based on this, embodiments of the present application provide a vehicle information processing method and system. By using the vehicle central control platform as the data provider for the vehicle information display device, the information display is more comprehensive, and the hardware communication capabilities of the vehicle central control platform are utilized to reduce the information display cost. The details are as follows:

The vehicle information display device 1 can be a mobile phone terminal or a head-up display HUD. There is no specific restriction on the hardware form of the vehicle information display device 1. The vehicle information display device 1 is powered by the handrail power supply on the vehicle.

[0028] In a preferred embodiment, if Figure 1 As shown, the method includes:

[0029] The vehicle-mounted central control platform executes:

[0030] S11. Encapsulate the vehicle comprehensive information generated by the multimedia entertainment and information system according to the target protocol supported by the vehicle information display device to obtain processed vehicle comprehensive information.

[0036] In a preferred embodiment, see Figure 3 , Figure 3 The figure shows a schematic diagram of information transmission between a vehicle-mounted central control platform and a vehicle information display device provided by an embodiment of the present application. Figure 3 As shown, in addition to the multimedia entertainment and information system E1, the vehicle central control platform is also equipped with a preset information transfer service E2. Specifically, the multimedia entertainment and information system E1 uses the preset information transfer service E2 to achieve communication with the vehicle information display device.

[0037] In a preferred embodiment, the method further comprises:

[0038] The multimedia entertainment and information system E1 executes: transmitting the generated vehicle comprehensive information to the preset information transfer service through inter-process communication (IPC).

[0039] The preset information transfer service E2 executes: encapsulating the vehicle comprehensive information according to the target protocol to obtain the processed vehicle comprehensive information, and transmitting the processed vehicle comprehensive information to the vehicle information display device 1 via a given communication method.

[0040] In this application, the IPC communication adaptation for transmitting the comprehensive vehicle information generated by the multimedia entertainment and information system E1 and the preset information transfer service E2 is completed in advance, so that the comprehensive vehicle information generated by the multimedia entertainment and information system E1 can be transmitted to the preset information transfer service E2 in a cross-process communication manner.

[0041] In a specific embodiment, the preset information transfer service E2 provided in this application, on the one hand, calls the wireless communication method (such as BLE) provided by the on-board central control platform itself to realize communication with the vehicle information display device 1, and on the other hand, supports cross-process communication IPC method to transmit data with the multimedia entertainment and information system E1. It only needs to be adapted and reused on the on-board central control platform in advance. The specific adaptation method refers to the process of establishing IPC communication between different application services, and can be adapted through the central control display screen provided by the on-board central control platform. It will not be described in detail here. In this application, different car companies and different car models can realize the communication between the multimedia entertainment and information system E1 and the preset information transfer service E2 through the preset information transfer service E2, and only need to use the wireless communication method provided by the on-board central control platform itself to reduce the implementation cost of the head-up display HUD.

[0042] Preferably, the multimedia entertainment and information system E1 includes multiple in-vehicle application services, the vehicle comprehensive information includes application service information generated by each in-vehicle application service, the target protocol includes a transmission sub-protocol corresponding to each in-vehicle application service, the application service information includes multiple vehicle business information, and the transmission sub-protocol defines the vehicle business information supported and displayed by the vehicle information display device 1.

[0043] Specifically, such as Figure 3 As shown, multiple in-vehicle application services include but are not limited to at least one of the following items: vehicle control service, navigation service and multimedia entertainment service, wherein the application service information corresponding to the vehicle control service is vehicle status information, the application service information corresponding to the navigation service is vehicle navigation information, and the application service information corresponding to the multimedia entertainment service is multimedia information.

[0044] The multiple vehicle service information indicated by the vehicle status information includes but is not limited to at least one of the following items: the current gear position of the vehicle, the vehicle operation scene and the current speed of the vehicle.

[0045] The multiple vehicle business information indicated by the vehicle navigation information includes but is not limited to at least one of the following items: current road, turn icon, remaining distance on the current road, address description, ETA (Estimated Time of Arrival) information, and estimated remaining range.

[0046] The multimedia information is determined by the multimedia entertainment service. Taking the multimedia entertainment service as a music application service as an example, the multiple vehicle business information indicated includes but is not limited to at least one of the following items: song name, song album and song duration.

[0047] In a preferred embodiment, the method further comprises:

[0048] In-vehicle application services, perform:

[0049] Call the cross-process interface corresponding to the preset information transfer service E2, convert and process the application service information generated by itself according to the corresponding application data protocol and basic data transmission protocol, obtain application encapsulation data, and pass the application encapsulation data to the preset information transfer service E2 through the cross-process interface.

[0050] In a specific embodiment, the application data protocol defines the designated vehicle service information to be transmitted by the in-vehicle application service and the encapsulation method of the designated vehicle service information.

[0051] The basic data transmission protocol defines the attribute information of application service information and its corresponding encapsulation method, wherein the attribute information of application service information includes but is not limited to at least one of the following items: the in-vehicle application service to which the application service information belongs and the version number of the application data protocol corresponding to the application service information.

[0052] In a specific embodiment, taking the vehicle control service as an example, the vehicle control service calls the cross-process interface corresponding to the preset information transfer service E2, and encapsulates or converts the specified vehicle business information (such as the vehicle's current gear and speed) in the generated vehicle status information according to the application data protocol corresponding to the vehicle control service defined in the cross-process interface to obtain the first encapsulated data, and then uses the basic data transmission protocol to determine the second encapsulated data corresponding to the vehicle status information, combines the first encapsulated data with the second encapsulated data, determines the application encapsulated data corresponding to the vehicle control service, and passes the application encapsulated data corresponding to the vehicle control service to the preset information transfer service E2 through the cross-process interface.

[0053] In a preferred embodiment, the method further comprises:

[0054] Preset information transfer service E2, execute:

[0055] The application encapsulation data is parsed according to the basic data transmission protocol to obtain attribute information corresponding to the application encapsulation data, which includes the target vehicle-mounted application service to which the application encapsulation data belongs and the version number of the corresponding application data protocol. The version number of the target transmission sub-protocol corresponding to the target vehicle-mounted application service on the vehicle information display device 1 is retrieved. Based on the comparison result between the version number of the application data protocol corresponding to the application encapsulation data and the version number of the target transmission sub-protocol, the application service information indicated by the application encapsulation data is transmitted to the vehicle information display device 1 in a given communication method.

[0056] In a specific embodiment, the transmission sub-protocol defines the vehicle business information and packaging method supported by the vehicle information display device 1, and the application data protocol defines the specified vehicle business information to be transmitted by the on-board application service and the packaging method of the specified vehicle business information. This shows that the transmission sub-protocol and the application data protocol are both used to limit the content of the data to be transmitted. In this application, for the same on-board application service, if the version number of the corresponding transmission sub-protocol is the same as the version number of the application data protocol, it means that the vehicle business information and packaging method supported by the vehicle information display device 1 are exactly the same as the specified vehicle business information to be transmitted by the on-board application service and the packaging method of the specified vehicle business information.

[0057] If the version number of the corresponding transmission sub-protocol is different from the version number of the application data protocol, it means that the vehicle business information supported and displayed by the vehicle information display device 1 and the packaging method are different from the specified vehicle business information to be transmitted by the on-board application service and the packaging method of the specified vehicle business information.

[0058] Based on this, the method provided by this application also includes:

[0059] The preset information transfer service E2 encapsulates application data and performs:

[0060] If the comparison result of the target transmission sub-protocol version number corresponding to the application encapsulation data is consistent with the version number of the application data protocol, it means that the target transmission sub-protocol and the application data protocol are exactly the same, then the application encapsulation data is directly transmitted to the vehicle information display device 1 as application display encapsulation information in a given communication method.

[0061] If the comparison result of the version number of the target transmission subprotocol corresponding to the application encapsulation data is inconsistent with the version number of the application data protocol, it means that the target transmission subprotocol and the application data protocol are different. Then the application service information indicated by the application encapsulation data is re-encapsulated using the target transmission subprotocol and the basic data transmission protocol, and the application display encapsulation information is obtained and transmitted to the vehicle information display device in a given communication method.

[0062] In a specific embodiment, taking multimedia entertainment service as an example, assuming that the multimedia entertainment service is a music service, the application data protocol version corresponding to the music service is MUSIC_V1, and the transmission sub-protocol version corresponding to the music service is HUD_MUSIC_V1. At this time, the application data protocol corresponding to the music service is the same as the transmission sub-protocol corresponding to the music service. There is no need to perform protocol conversion, and the application encapsulation data corresponding to the music service can be directly used as the application display encapsulation information.

[0063] The application service information received by the preset information transfer service E2 from the music service includes the name of the song being played, the duration of the song, and the progress of the song being played. At this time, the application data protocol version corresponding to the music service is MUSIC_V1. The vehicle information display device 1 does not support the display of the progress of the song being played, but only supports the display of the name of the song being played and the duration of the song being played. That is, the transmission sub-protocol version corresponding to the music service is HUD_MUSIC_V2. At this time, the application data protocol version corresponding to the music service is different from the transmission sub-protocol version. It is necessary to use the target transmission sub-protocol and the basic data transmission protocol to re-encapsulate the application service information indicated by the application encapsulation data to obtain the application display encapsulation information.

[0064] In a preferred embodiment, the method further comprises:

[0065] The vehicle information display device 1 executes:

[0066] Use the basic data transmission protocol to parse the received application display package information, determine the target vehicle-mounted application service to which the application service display information belongs, use the target transmission sub-protocol corresponding to the target vehicle-mounted application service to parse the application display package information, obtain the application service information to be displayed corresponding to the target vehicle-mounted application service, and update and display the application service information to be displayed corresponding to different vehicle-mounted application services according to the given display priority.

[0067] In the above technical solution of the present application, the vehicle information display device 1 obtains the application service information corresponding to each vehicle-mounted application service in the vehicle-mounted central control platform through the preset information transfer service E2, thereby expanding the data display range of the vehicle information display device 1, making the displayed information more comprehensive, and also providing the vehicle information display device 1 with the possibility of responding to different vehicle data display requirements of users. Specifically, as provided in the present application, the received data is selectively displayed according to the display priority corresponding to different vehicle-mounted application services.

[0072] In a specific embodiment, the vehicle information display device provided by the present application provides a strategy for adjusting the display priority of different vehicle-mounted application services in combination with the vehicle's current driving scene and the data display priority adjustment data table. Specifically, the vehicle's current driving scene includes a high-speed driving scene, a traffic congestion scene, etc. For example, when the vehicle is driving at high speed, more emphasis is placed on speed and navigation information, and the display priority of vehicle control services and navigation services is increased, and so on.
