From the design concept of the entire vehicle domain control, it is necessary to consider that the MCU and MPU must meet a certain level of functional safety in the vehicle domain control to meet the control capability output of the vehicle domain control. In addition, the general interface GPIO is set to control the output commands of other domain controllers of the vehicle (such as accelerator opening, brake switch, input wake-up, output wake-up, etc.). Set CAN, ETH, and LIN interfaces for communication connections to transmit different data types; set the basic clock crystal oscillator for power-on and power-on clock synchronization; set dual power supply to consider that the overall vehicle domain control will not fail due to power supply failures .
From a functional point of view, the vehicle domain control is a multi-dimensional quasi-centralized central processing unit, which not only needs to perform low-level parking control functions, but also needs to perform overall control of the entire chassis system, and also needs to be responsible for the central gateway. functions such as communication routing and forwarding.
