Other features and effects of the present invention will be apparent from the following description of the drawings, wherein: FIG. 1 is a block diagram illustrating that the existing vehicle control area network system is separately controlled by two electronic control units. The operation of the instrument module and the infotainment module; and FIG. 2 is a block diagram illustrating an embodiment of the control module and the area network system for controlling the instrument display and infotainment of the automobile.

Referring to FIG. 2, an embodiment of the control module 2 for controlling the display and infotainment of an automobile of the present invention is adapted to be disposed in a car, the car comprising a meter module 31, an infotainment module 32, and a confluence Row 33.

The meter module 31 is used to display driving data of the automobile such as vehicle speed, engine speed, oil quantity, engine temperature and the like. The infotainment module 32 includes at least one audio-visual device such as a DVD player, a display device, an audio device, and the like.

The control module 2 includes a memory unit 21, a processing unit 22, and a network interface 23. The memory unit 21 stores a first operating system 24 and a second operating system 25 different from the first operating system 24; preferably, the operating systems are QNX, Linux or Android operating systems.

The processing unit 22 is adapted to electrically connect the meter module 31 with the The infotainment module 32 is electrically connected to the memory unit 21 and can execute the first operating system 24 to control the operation of the meter module 31, and can execute the second operating system 25 to control the infotainment module 32. Operation. In particular, the processing unit 22 can simultaneously execute the first operating system 24 and the second operating system 25, in which case the first operating system 24 and the second operating system 25 share the computing power of the processing unit 22. The storage space of the memory unit 21 and the network bandwidth of the network interface 23. Preferably, the existing Microvisor, Xen, or Hypervisor virtualization technology can be utilized to implement the technical means of simultaneously executing two different operating systems on a single module.

When the first operating system 24 is executed, the processing unit 22 can receive at least one message packet that is displayed by the meter module 31 and includes vehicle status information, so that the processing unit 22 receives the The message packet controls the meter module 31 to display the car status information. For example, the automobile further includes an electronic control unit 35 electrically connected to the busbar 33 and used to control the engine 34 of the automobile. When the engine 34 is in operation, the electronic control unit 35 transmits a message packet containing, for example, engine speed to The bus bar 33, when the processing unit 22 executes the first operating system 24, receives the message packet including the engine speed from the bus bar 33, and controls the meter module 31 to display the engine speed.

The network interface 23 can be connected to a short-range wireless communication network and can receive a control signal related to the infotainment module 32 via the short-range wireless communication network; wherein the processing unit 22 can execute the second operating system Controlling the control signal according to the network interface 23 at 25 o'clock The operation of the infotainment module 32. Preferably, the network interface 23 can use Wi-Fi technology or Bluetooth technology, and is not limited thereto. For example, the network interface 23 can communicate with a mobile device 36 using Wi-Fi or Bluetooth technology. The mobile device 36 can execute an application to transmit the control signal such that the processing unit 22 receives the control signal. The operation of the infotainment module 32 is then controlled, for example, to control the infotainment module 32 to play music or movies, and the like.

Further, an embodiment of the vehicle control area network system of the present invention includes the bus bar 33 and the control module 2 described above.

In summary, the present invention is used to control a meter display and infotainment control module and a regional network system of an automobile.
