[0036] It should be particularly noted that any symbols and / or numbers in the specification that are not marked in the accompanying drawings are not drawing marks.

[0037] The optional embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0038] The embodiment provided in this application is an embodiment of a display system.

[0039] Combine the following Figure 1 The embodiments of the present application are described in detail.

[0040] The embodiment of the present application provides a display system 100 , including an uplink module 101 and a downlink module 102 .

[0041] The uplink module 101 is configured to receive and store indication signals of all communication types.

[0042] The indication signal refers to a signal that controls the display icon on the instrument display screen 103. For example, for an icon on the display screen 103 that warns the user to fasten the seat belt, the uplink module 101 receives the indication signal through the Ethernet bus; if the indication signal is 0x00, it indicates that the icon is not displayed; if the indication signal is 0x01, it indicates that the icon is displayed; if the indication signal is 0x02, the indication icon flashes slowly; if the indication signal is 0x03, the indication icon flashes quickly.

[0043] In the embodiment of the present application, the indication signals of all communication types are uniformly received by the uplink module 101. The uniformity and multiplexing of the received indication signals are improved, so that the indication signals of all communication types are uniformly managed.

[0044] The host (such as the central control unit of a car) and the screen usually need to use various communication protocols to achieve data exchange and information transmission. These communication protocols ensure the normal communication between the host and the screen so that the correct information can be displayed on the screen and respond to user operations.

[0045] In some specific embodiments, the indication signals of all communication types include indication signals transmitted by the regional controller and / or the vehicle dynamics controller via a controller area network bus, an Ethernet bus, a low voltage differential signal, a bidirectional two-wire synchronous serial bus, a serial peripheral device interface bus and / or a SOME / IP bus. The communication types of the embodiments of the present application are not limited thereto.

[0046] The regional controller (Power Data Centers, PDC for short) mainly integrates the following functions, including body comfort, chassis, power, thermal management, intelligent driving, big data, power mode, energy consumption data service, function degradation and exception handling, vehicle calibration, SOA service, etc. PDC connects various small controllers in the car to control windows, wipers, lights, etc.

[0047] The vehicle dynamics controller (VDC) is one of the functions of the electronic stability program (ESP) system. As one of the computing units, VDC is mainly responsible for AVM and vehicle power management. VDC sends power status to other controllers, such as wake-up, to ICC, PDC, CSC, and other domain controllers such as ETC, power amplifier, etc.

[0048] VDC organically integrates the control systems of the vehicle's major assemblies, such as braking, driving, suspension, steering, and engine, in terms of function and structure. This enables the vehicle to have good directional stability and exhibit optimal driving performance under various adverse conditions, such as icy and snowy roads, open roads, curved roads, and when taking evasive actions, changing lanes, braking, accelerating, and driving downhill. It responds to different loads, different tire pressures, and different degrees of tire wear.

[0049] Controller Area Network (CAN) is a serial communication protocol bus for real-time applications. It can use twisted pair cables to transmit signals and is one of the most widely used fieldbuses in the world. The CAN protocol is used for communication between various components in the car to replace expensive and bulky distribution harnesses. The robustness of the protocol extends its use to other automation and industrial applications. The characteristics of the CAN protocol include complete serial data communication, real-time support, a transmission rate of up to 1Mb / s, and 11-bit addressing and error detection capabilities.

[0050] Ethernet bus refers to a system that is technically compatible with commercial Ethernet (i.e. IEEE802.3 standard), but can be used in production sites and realize two-way serial multi-node digital communication between microcomputerized measurement and control equipment in terms of material selection, product strength, applicability and practicality, interoperability, reliability, anti-interference and intrinsic safety during product design. It is also called an open, digital, multi-point communication underlying control network. It has broad application prospects in automation systems in manufacturing, process industry, transportation, buildings, etc.

[0051] Low-Voltage Differential Signaling (LVDS bus for short) is a high-speed data transmission protocol suitable for transmitting high-quality image and video signals between a host and a display 112 .

[0052] I2C is a two-wire synchronous serial bus (Inter-Integrated Circuit, or I2C for short), a serial communication protocol that is usually used to connect a host computer and peripherals such as a screen. It can transmit low-speed data such as configuration settings, control commands, etc.

[0053] Serial Peripheral Interface (SPI) is a protocol for full-duplex communication between devices, suitable for high-speed data transmission. It can be used for data exchange between the host and the screen.

[0054] SOME / IP bus, full name Scalable service-oriented middleware over IP, is the core communication protocol for the current automotive industry to implement SOA architecture. SOME / IP protocol manages vehicle information in units of services. Services can include various callable methods and event notification groups. EventGroup transmits information through Service Interface to share and distribute services on demand. SOME / IP is located at layers 5-7 of the OSI seven-layer model and needs to run on the TCP / IP protocol stack, that is, all SOME / IP messages are IP messages and TCP / UDP messages.

[0055] In some specific embodiments, Figure 2 As shown, the uplink module 101 is arranged in the cockpit domain controller 111 .

[0056] The cockpit space center (CSC) 111 is connected to a display 112 to display various alarm information and entertainment information. The CSC is composed of a microcontroller unit and a system on chip.

[0057] Microcontroller Unit (MCU): MCU is a dedicated integrated circuit that usually contains a processor core, memory, input / output interfaces, timers and other functions. MCU is usually used to control small embedded systems, such as automotive sensors, actuators, switches, etc., as well as some simple calculation and control tasks. MCU has low power consumption and is suitable for real-time control and embedded applications. In a car, MCU may be used to control simpler functions such as door locks, windows, lights, etc.

[0058] System on Chip (SOC for short) is responsible for entertainment-related functions. SoC runs the QNX real-time operating system and Android / Linux virtual machine system. The operating system running on SoC can meet the functional requirements of the entertainment domain, such as telephone, media playback, map positioning, FMRadio, vehicle settings, reversing images, driving records, etc. The QNX system running on SoC includes CAN, Ethernet, TDM, I2C, SPI, UART interfaces, as well as MCU communication module, Chime playback module, safety monitoring module (Safety Monitor) and corresponding driver modules.

[0059] MCU is responsible for vehicle control safety-related functions, and SOC is responsible for entertainment-related functions. CSC is one of the four core controllers of a car and must be configured for all models. CSC provides an SOA interface to achieve software and hardware decoupling. As the control brain of the display and audio-visual system, it supports multi-screen driving, sensor data collection, big data, energy management, data management, gateway, diagnosis, OTA and other services, and cooperates with other computing platforms to complete display interaction needs and create a central computing platform.

[0060] In the vehicle system, MCU and SOC can coexist and play their respective advantages. MCU is mainly used to control and manage the basic functions of the vehicle, such as controlling CAN bus communication and sensor interface. SOC is used to provide more complex functions, such as entertainment system, navigation system, and communication system. The relationship between the two is mutual cooperation to realize a comprehensive automotive electronic system.

[0061] The uplink module can be set in the MCU or in the SOC, but the embodiments of the present application are not limited thereto.

[0062] The downlink module 102 is in communication connection with the uplink module 101 and is configured to call indication signals of all communication types from the uplink module 101 for verification and perform display control based on the indication signals that pass the verification.

[0063] The downlink module 102 is used to verify whether the indication signal received by the uplink module 101 is an indication signal for controlling display, that is, a qualified indication signal. If it is a qualified indication signal, the qualified indication signal is used for display control; if it is an unqualified indication signal, no display control is performed.

[0064] In some specific embodiments, Figure 2 As shown, the downlink module 102 is disposed on the display 112 .

[0065] Furthermore, the display 112 includes a display screen 103, and the display screen 103 includes a display icon that can be lit and is set at a preset position, and the display icon corresponds to the indication signal. For example, an icon on the display screen 103 that warns the user to fasten the seat belt is set at a preset position of the display screen 103 (such as the upper left corner of the display screen 103); the icon has multiple display modes: no icon display, icon display, icon slow flashing, and icon fast flashing; if the indication signal is 0x00, it indicates that the icon is not displayed; if the indication signal is 0x01, it indicates that the icon is displayed; if the indication signal is 0x02, it indicates that the icon is slowly flashing; if the indication signal is 0x03, it indicates that the icon is fast flashing.

[0066] Fixing the display icons at the preset positions helps the driver to quickly identify and obtain information, improving user experience and safety. The display icons at the preset positions can establish the driver's visual habits, allowing them to obtain the required information without being distracted. At the same time, the downlink module 102 can quickly transmit the indication signal to the corresponding display icon in the display screen 103, improving the display efficiency.

[0067] Correspondingly, the downlink module 102 is configured to control the display of the corresponding display icon based on the verification qualified indication signal.

[0068] In some specific embodiments, the downlink module 102 is further configured to: obtain a current display image from a preset position, and when it is determined that the display icon is displayed abnormally based on the current indication signal of the display icon and the current display image, control the display of the display icon based on the current indication signal.

[0069] In this specific embodiment, whether the display icon in the display screen 103 is displayed normally is verified. If the current display image of the display icon does not match the current indication signal, that is, an abnormal display occurs, the display icon is forced to be displayed normally again based on the current indication signal, thereby ensuring the reliability and effectiveness of the display icon.

[0070] In some specific embodiments, the downlink module 102 is further configured to determine that the display icon is abnormally displayed based on the current indication signal of the display icon and the current display image, including: obtaining display characteristic information of the display icon based on the current indication signal of the display icon; matching the current display image based on the display characteristic information to obtain a matching degree; when the matching degree is lower than a preset matching degree threshold, determining that the display icon is abnormally displayed.

[0071] If the display screen 103 crashes, the display icon in the display screen 103 cannot be displayed normally; for this reason, the present specific embodiment first obtains the display characteristic information of the normal display icon in the display screen 103 according to the current indication signal, for example, the icon that warns the user to fasten the seat belt, the current indication signal is 0x01, indicating that the icon is displayed, then the icon should be displayed normally at the preset position, and the display characteristic information of the display icon includes the position information of each of the multiple pixels of the display icon and the pixel RGB value of each of the multiple pixels; the display characteristic information of the display icon is matched with the current display image obtained at the preset position, that is, each pixel RGB value in the display characteristic information is compared with the pixel RGB value at the same pixel position in the current display image, when the pixel RGB values ​​are the same, the pixels at the same pixel position match; when the pixel RGB values ​​are different, the pixels at the same pixel position do not match; the matching degree is obtained through the matching results of all pixels; and then the display icon is determined to be displayed normally through the preset matching degree threshold. Thus, the reliability and effectiveness of the display icon are ensured.

[0072] The embodiment of the present application receives the indication signals of all communication types uniformly through the uplink module 101. The uniformity and multiplexing of the received indication signals are improved so as to uniformly manage the indication signals of all communication types. The downlink module 102 verifies whether the indication signal received by the uplink module 101 is an indication signal for controlling the display, that is, a qualified indication signal. If it is a qualified indication signal, the display control is performed using the qualified indication signal; if it is an unqualified indication signal, no display control is performed. Thus, the reliability and effectiveness of the displayed icon are ensured.

[0076] Step S302: The downlink module calls the indication signals of all communication types from the uplink module for verification, and performs display control based on the indication signals that pass the verification.

[0077] The embodiment of the present application receives the indication signals of all communication types uniformly through the uplink module. The uniformity and multiplexing of the received indication signals are improved so as to uniformly manage the indication signals of all communication types. The downlink module verifies whether the indication signal received by the uplink module is an indication signal for controlling the display, that is, a qualified indication signal. If it is a qualified indication signal, the display control is performed using the qualified indication signal; if it is an unqualified indication signal, no display control is performed. This ensures the reliability and effectiveness of the displayed icon.
