The software deployment of vehicle domain control is mainly divided into several aspects: vehicle control-related SWC, gateway-related SWC, and intelligent driving system SWC. The deployment principle is that functions with high real-time requirements are deployed in real-time cores, functions with high computing requirements are deployed in computing cores, and functions with high functional safety requirements are deployed in lockstep cores.
The MCU deploys software modules such as power control, chassis control, communication management, local diagnostics, electrical performance, and device abstraction. The corresponding computing power is mainly CPU logical computing power, which generally meets 10K DMIPS. At the same time, the MCU needs to undertake the entire VDC network wake-up, diagnostic functions, and power management related functions.
As the ultimate boss of vehicle control, VDC needs to undertake the entire network management function, in which network management involves network management state machine design and network wake-up design.
