Embodiments provided herein, namely, embodiments of a display system.

An embodiment of the present application is described in detail below with reference to fig. 1.

The embodiment of the application provides a display system 100, which comprises an uplink module 101 and a downlink module 102.

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

The indication signal is a signal for controlling the display of a display icon on the meter display screen 103. For example, an icon on the display 103 alerting the user that the seat belt is being tethered, the uplink module 101 receives an indication signal via the ethernet bus; if the indication signal is 0x00, indicating that the icon is not displayed; if the indication signal is 0x01, indicating to display an icon; if the indication signal is 0x02, the indication icon flashes slowly; if the indication signal is 0x03, the indication icon flashes rapidly.

In the embodiment of the present application, the uplink module 101 receives the indication signals of all communication types in a unified manner. The uniformity and reusability of the received indication signals are improved, so that the indication signals of all communication types are managed in a unified way.

Communication protocols of various communication types are typically required between a host (e.g., a central control unit of an automobile) and a screen to effect data exchange and information transfer. These communication protocols ensure proper communication between the host and the screen to display the correct information on the screen and respond to user actions.

In SOME embodiments, the indication signals of all communication types include indication signals transmitted by the zone controller and/or the vehicle dynamics controller via a controller area network bus, an ethernet bus, a low voltage differential signal, a bi-directional two-wire synchronous serial bus, a serial peripheral interface bus, and/or a SOME/IP bus. The communication type of the embodiment of the present application is not limited thereto.

The regional controller (Power Data Centers, PDC) mainly integrates the following functions, including functions of comfort of a vehicle body, chassis, power, heat management, intelligent driving, big data, power supply modes, energy consumption data service, function degradation and exception handling, whole vehicle calibration, SOA service and the like. The PDC is connected with each small controller in the vehicle to control the vehicle window, the windshield wiper, the lamplight and the like.

The vehicle dynamic controller (acronym Vehicle Dynamics Control, VDC) is one of the functions of the electronic stability program (acronym Electronic Stability Program, ESP) system. The VDC is used as one of the computing units and is mainly responsible for AVM, power management of the whole vehicle and the like. The power state, e.g., wake up, is sent to the other controllers via the VDC. To ICC, PDC and CSC, and other domain controllers such as ETC, power amplifiers, ETC.

VDC organically integrates control systems of main assemblies such as braking, driving, suspension, steering and engine of an automobile in function and structure, so that the automobile has good directional stability on different loads, different tire pressures and different degrees of tire wear under various severe working conditions, such as running on ice and snow roads, on split roads, on curve roads, running under working conditions such as avoidance action lane shifting, braking, acceleration and downhill slope, and the like, and the automobile shows optimal running performance.

The controller area network bus (english acronym Controller Area Network, abbreviated as CAN bus) is a serial communication protocol bus for real-time applications, which CAN use twisted pair wires 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 an automobile to replace expensive and heavy wiring harnesses. The robustness of this protocol extends its use to other automation and industrial applications. The features of the CAN protocol include serial data communication for integrity, providing real-time support, transmission rates up to 1Mb/s, and 11-bit addressing and error detection capabilities.

The ethernet bus is technically compatible with commercial ethernet (i.e., IEEE802.3 standard), but can be applied to a system for realizing bidirectional serial multi-node digital communication between microcomputerized measurement control devices in a production field, such as an open, digital, and multi-point communication bottom control network in terms of material selection, product strength, applicability, practicality, interoperability, reliability, anti-interference, and intrinsic safety, etc. in product design. It has wide application prospect in the automatic system in the aspects of manufacturing industry, flow industry, traffic, building and the like.

A Low voltage differential signal (english acronym Low-Voltage Differential Signaling, abbreviated as LVDS bus), a high speed data transfer protocol, is suitable for transferring high quality image and video signals between a host and a display 112.

A bidirectional two-wire synchronous serial bus (english full-name Inter-Integrated Circuit, I2C for short), a serial communication protocol, is commonly used to connect a host and a peripheral device, such as a screen. It may transmit low speed data such as configuration settings, control commands, etc.

Serial peripheral interface bus (english full name Serial Peripheral Interface, abbreviated SPI), a protocol for full duplex communication between devices, is suitable for high-speed data transmission. It can be used for data exchange between the host and the screen.

SOME/IP bus, known as Scalable service-Oriented Middleware over IP, is the communication protocol that is the most core for realizing SOA architecture in the automotive industry at present. The SOME/IP protocol manages whole vehicle information services in service units, which may include various callable methods and event notification groups EventGroup delivering information through Service Interface to share on-demand distribution services. Layers 5-7 of the SOME/IP on the OSI seven layer model need to run on top of the TCP/IP protocol stack, i.e., all SOME/IP messages are IP messages and TCP/UDP messages.

In some embodiments, as shown in fig. 2, the uplink module 101 is disposed in the cabin controller 111.

The capsule domain controller 111 (CSC, english full name Cockpit Space Center) is connected to the display 112, and displays various alert information and entertainment information. CSC is comprised of a microcontroller unit and a system-on-chip.

Microcontroller unit (english full name Microcontroller Unit, abbreviated MCU): an MCU is an application specific integrated circuit that typically includes a processor core, memory, input/output interfaces, and timers. MCUs are commonly used to control small embedded systems, such as sensors, actuators, switches, etc. of automobiles, as well as some simple computing and control tasks. The MCU has lower power consumption and is suitable for real-time control and embedded application. In automobiles, MCUs may be used to control simpler functions of door locks, windows, lights, and the like.

System On Chip (SOC) is responsible for entertainment domain related functions. The SoC runs a QNX real-time operating system and an android/Linux virtual machine system, and the operating system running on the SoC can meet the functional requirements of entertainment domains, such as functions of telephone, media playing, map positioning, FMradio, vehicle setting, reversing images, driving records and the like. The QNX system running on the SoC comprises a CAN, ethernet, TDM, I2C, SPI, UART interface, and further comprises an MCU communication module, a Chime playing module, a Safety monitoring module (Safety Monitor) and a corresponding driver module.

The MCU is responsible for the related functions of the car control safety class, and the SOC is responsible for the related functions of the entertainment domain. CSC is one of the large core controllers of the car 4 and all the car models need to be configured. The CSC provides an SOA interface to realize software and hardware decoupling. As a control brain of a display and audio-visual system, the system supports multi-screen driving, sensor data collection, and services such as big data, energy management, data management, gateway, diagnosis, OTA and the like, and works for displaying interaction requirements are completed by matching with other computing platforms, so that a central computing platform is created.

In the vehicle-mounted system, the MCU and the SOC can exist at the same time, and the advantages of the MCU and the SOC are exerted. The MCU is mainly used for controlling and managing basic functions of the vehicle, such as controlling CAN bus communication and sensor interfaces. The SOC is then used to provide more complex functions such as entertainment systems, navigation systems, communication systems. The relationship between the two is that of cooperating to achieve a comprehensive automotive electronics system.

The uplink module can be set in the MCU or in the SOC, and the embodiment of the present application is not limited thereto.
