example 1

[0113] Example 1: see Figure 13B As shown, where the data flow in Surround Display / Sentry Mode:

[0114] Surround view display: the camera first sends video data to the ADAS / AD domain controller, and the internal image signal processing (ISP) module of the ADAS / AD domain controller processes the raw data into RGB / YUV (RGB and YUV are two types of colors) Encoding method) data format data, and then forward the data to the human-computer interaction domain controller, and the human-computer interaction domain controller forwards the video data to the central control screen for display.

[0115] Sentinel mode: the camera first sends video data to the ADAS / AD domain controller, and the ISP inside the ADAS / AD domain controller processes the raw data into RGB / YUV data format data, and then forwards the data to the human-computer interaction domain controller, the human-machine The interactive domain controller performs personnel approach / intrusion detection. If illegal intrusion i...

example 2

[0116] Example 2: see Figure 13C As shown, the data flow of instrument display data: VCU collects chassis body control and power ECU information, and transmits the information required for display such as vehicle speed to the instrument processor, and the instrument processor renders the image through the image processing module (GPU), and then sends it to display on the instrument screen.

[0117] In the above architecture, due to the use of multiple independent domain controller architectures for the whole machine, the installation of the whole vehicle takes up a lot of space and requires additional video / Ethernet cable connections. On the other hand, in the above example, this architecture makes the data flow have more transfers, takes up more hardware resources, and consumes more power.

[0118] The present application provides another controller system and applications based on the controller system. It can deeply integrate the intelligent driving domain controller, hu...
