Due to the fact that the traditional instrument software has the safety function attribute, the instrument cannot be connected with the internet, and therefore the traditional instrument cannot realize quick iteration of a human-computer interaction interface of the instrument. If on the basis of the existing meter, the networking function is added to the meter system, the production cost of the vehicle enterprise is greatly increased. In addition, with the continuous iterative update of the display effect and the animation effect of the instrument, the current instrument software iteration mode mostly downloads the upgrade package through a vehicle-mounted entertainment system or other internet controllers, then transmits the upgrade package to the instrument through physical connection, and finally carries out the whole package upgrade by the instrument. However, the memory amount of a part of software packages is large, and may reach hundreds of megabytes, so that the current whole package upgrading technology has the following problems:

(1) the time consumption is long, the software package needs to be downloaded from the Internet, then the software package is transmitted to the instrument, and finally the instrument is upgraded in a whole package. The whole process is not only complicated, but also the memory quantity of the software package is large, so that the time consumption is long, and generally the whole upgrading process can exceed 10 minutes;

(2) the consumed flow is large, and due to the fact that the number of memories of a part of software packages is large, hundreds of megaflows are consumed for upgrading the instrument once;

(3) iteration is slow, once the meter software is produced in volume, in order to ensure stability and cost consideration, a car factory or a supplier generally pushes an upgrade package only when the meter problem is found.

(4) The man-machine interaction of the existing instrument interaction interface can only be controlled through a steering wheel key, and the operation is complex.

Therefore, in the embodiment, the human-computer interaction interface of the vehicle instrument is generated at the vehicle end, so that the instrument human-computer interaction interface is quickly upgraded and iterated through the vehicle APP; the function of fast iterative animation effect of the vehicle instrument is realized, the memory occupation of the vehicle instrument is greatly reduced, the reliability and the safety of the vehicle instrument are improved, and the vehicle instrument can be compatible with vehicle instruments with various sizes. The implementation scheme is equivalent to the implementation scheme of the man-machine interaction software compatible with various instrument sizes, and the application programs of the instruments are operated at the end of a vehicle, so that the problems that the man-machine interface of the instrument software is slow to update, the interaction is complex, the user personalization is difficult to realize and the display compatibility problem caused by different instrument sizes can be solved.

According to the above, in an exemplary embodiment, before integrating the vehicle meter related information, the method may further include: the communication connection between the vehicle instrument and the vehicle machine is established through a private controller domain network bus, a universal serial bus or a private Ethernet between the vehicle instrument and the vehicle machine, the vehicle instrument information and the vehicle instrument related information are synchronized to the vehicle machine, and the vehicle machine integrates the vehicle instrument related information. Or, establishing communication connection between the vehicle instrument and the vehicle machine through a vehicle controller domain network bus or a vehicle Ethernet, transmitting the vehicle instrument information and the vehicle instrument related information to the vehicle machine, and integrating the vehicle instrument related information by the vehicle machine. Specifically, as an example, as shown in fig. 3, in the present embodiment, information related to the meters, such as a vehicle speed, a rotation speed, a remaining oil amount, and a driving range, may be synchronously sent to the vehicle machine through a physical connection manner, such as a private CAN (Controller Area Network, CAN for short) Bus or a USB (Universal Serial Bus, USB for short), or a private ethernet between the meters and the vehicle machine. As another example, as shown in fig. 3, the present embodiment may also transmit the information related to the meters such as the vehicle speed, the rotation speed, the remaining oil amount, the driving range, etc. to the vehicle machine through the vehicle CAN bus or the vehicle ethernet network. In this embodiment, the car machine refers to a vehicle-mounted entertainment system in a vehicle.

According to the above description, in an exemplary embodiment, the vehicle machine integrates the vehicle instrument related information, and the process of generating the instrument interaction interface corresponding to the vehicle instrument related information includes: receiving vehicle instrument information and vehicle instrument association information which are sent to the vehicle machine by the vehicle instrument, and sending the vehicle instrument information and the vehicle instrument association information to a preset buffer area; and generating video stream data in the preset buffer area, and generating an instrument interactive interface corresponding to the vehicle instrument related information on the virtual screen inside the vehicle machine based on the video stream in the buffer area. Specifically, in this embodiment, after the vehicle-mounted device receives the vehicle instrument related information, an instrument interaction interface is generated through software development, and meanwhile, in order to not affect the whole vehicle entertainment function at the vehicle-mounted device end, the generated instrument interaction interface is operated on a virtual screen of an internal system of the vehicle-mounted device by default and is not displayed on a user-operable vehicle-mounted device interface. The concrete mode is as follows: the instrument interactive interface output generated by the software does not appear on the display screen of the vehicle, but the Hardware Composer writes the output content into a gralloc (graphics alloc, gralloc for short) buffer area to form video stream data and provide a completion barrier signal.

According to the above description, in an exemplary embodiment, the process of receiving and responding to a vehicle instrument interaction request initiated by a target object, and sending a generated instrument interaction interface to the vehicle instrument for playing includes: receiving and responding to a vehicle instrument interaction request generated by the target object on the vehicle instrument; converting the generated instrument interactive interface into video stream data, and transmitting the converted video stream data to the vehicle instrument through a preset physical channel; playing the video stream in the vehicle meter based on a decoder in the vehicle meter decoding the video stream.

Therefore, in the embodiment, the instrument control key is connected to the vehicle controller, and when the user operates the instrument steering wheel key, the instrument control key is actually in an instrument human-computer interaction software interface of the vehicle controller. The embodiment is equivalent to the method for realizing man-machine interaction by using the steering wheel.

Therefore, in the embodiment, instrument interaction software is developed at the car machine end, and the software is the same as other car machine software, and after a click event of a car machine screen is responded, the software is defaulted to run on a virtual screen; when the user needs to operate, the instrument man-machine interaction interface can be accessed by voice awakening or clicking the APP icon of the main interface. The instrument human-computer interaction interface refers to a human-computer interaction interface of a vehicle instrument or an instrument interaction interface in the vehicle instrument. Because instrument human-computer interface influences driver's driving safety, consequently, in the car machine internal system, this embodiment can be transferred the highest with this APP's system grade to guarantee under various system operation environment, can not retrieve this APP process.

Specifically, in this embodiment, after the vehicle-mounted device receives the vehicle instrument related information, an instrument interaction interface is generated through software development, and meanwhile, in order to not affect the whole vehicle entertainment function at the vehicle-mounted device end, the generated instrument interaction interface is operated on a virtual screen of an internal system of the vehicle-mounted device by default and is not displayed on a user-operable vehicle-mounted device interface. The concrete mode is as follows: the instrument interactive interface output generated by the software does not appear on the display screen of the vehicle, but the Hardware Composer writes the output content into a gralloc (graphics alloc, gralloc for short) buffer area to form video stream data and provide a completion barrier signal.

In an exemplary embodiment, prior to receiving and responding to a target object initiated vehicle meter interaction request, the system further comprises: connecting a control key of the vehicle instrument into a vehicle-mounted controller, and establishing connection between a vehicle steering wheel and the vehicle-mounted controller; and when the target object triggers a key on the vehicle steering wheel, generating a corresponding vehicle instrument interaction request. Therefore, in the embodiment, the instrument control key is connected to the vehicle controller, and when the user operates the instrument steering wheel key, the instrument control key is actually in an instrument human-computer interaction software interface of the vehicle controller. The embodiment is equivalent to the method for realizing man-machine interaction by using the steering wheel.

In an exemplary embodiment, prior to receiving and responding to the target object initiated vehicle meter interaction request, the system may further comprise: acquiring pre-developed interactive software applied to the vehicle instrument; loading the interactive software to the vehicle meter; acquiring a click action of the target object on the vehicle instrument to the interactive software, and generating a corresponding vehicle instrument interaction request on the vehicle instrument based on the click action; or acquiring a voice awakening instruction of the target object to interactive software on the vehicle instrument, and generating a corresponding vehicle instrument interaction request based on the voice awakening instruction. The schematic diagram of the architecture of the interactive software developed and applied to the vehicle instrument at the vehicle end in this embodiment is shown in fig. 4, and in fig. 4, based on the information related to the instruments such as the vehicle speed, the rotation speed, the oil amount, the remaining oil amount, and the driving range, an interactive software APP applied to the vehicle instrument is developed and generated by combining an instrument service layer, an instrument data processing layer, an OS (Operating System, abbreviated as OS) and a BSP (Board Support Package, abbreviated as BSP) layer at the vehicle end. Therefore, in the embodiment, instrument interaction software is developed at the car machine end, and the software is the same as other car machine software, and after a click event of a car machine screen is responded, the software is defaulted to run on a virtual screen; when the user needs to operate, the instrument man-machine interaction interface can be accessed by voice awakening or clicking the APP icon of the main interface. The instrument human-computer interaction interface refers to a human-computer interaction interface of a vehicle instrument or an instrument interaction interface in the vehicle instrument. Because instrument human-computer interface influences driver's driving safety, consequently, in the car machine internal system, this embodiment can be transferred the highest with this APP's system grade to guarantee under various system operation environment, can not retrieve this APP process.

In summary, the present application provides a vehicle instrument interaction system, which first obtains vehicle instrument information and vehicle information associated with a vehicle instrument, and records the vehicle information as vehicle instrument associated information; integrating the vehicle instrument correlation information to generate an instrument interaction interface corresponding to the vehicle instrument correlation information; adjusting the generated instrument interaction interface based on the screen size of the vehicle instrument so as to enable the instrument interaction interface to be matched with the screen size; and finally, receiving and responding a vehicle instrument interaction request initiated by the target object, and sending the generated instrument interaction interface to the vehicle instrument for playing to complete the interaction between the vehicle instrument and the target object. Wherein the vehicle meter information includes: screen size of vehicle instrument; the vehicle meter related information includes: the vehicle speed of the current vehicle, the rotating speed of the current vehicle, the remaining oil quantity of the current vehicle and the driving range of the current vehicle. Therefore, the system gradually realizes the user individuation and rapid iteration capability by means of the vehicle-mounted software, and after various data of the instrument are obtained from the vehicle-mounted end, the instrument human-computer interaction application software is developed at the vehicle-mounted end. The vehicle machine acquires instrument data in various ways, namely acquiring the instrument data through a whole vehicle CAN network or an Ethernet network, and acquiring the instrument data through a USB (universal serial bus), a CAN (controller area network) line and the like which are physically connected with the vehicle machine. And after the vehicle machine completes the development of the human-computer interaction interface of the instrument according to the received instrument size, the vehicle machine performs interface self-adaptive adaptation according to the instrument size, converts the human-computer interaction interface of the instrument into an H.264 or H.265 video file and transmits the video file to the instrument for playing and displaying. And controlling video data, namely firstly, immediately establishing data communication with the instrument after the whole vehicle is electrified to generate a man-machine interaction video stream, and then transmitting the man-machine interaction video stream to the instrument for playing. The user can switch the favorite instrument human-computer interaction interface on the car machine application software. Secondly, in order to not influence the operation of the vehicle-mounted computer-human interaction, the instrument human-computer interaction interface is displayed on a virtual screen of the vehicle-mounted computer by default, and when a user needs the instrument human-computer interaction interface, the user can also turn to a main interface screen for displaying.
