and step S103, completing power-on based on the control module, and controlling the plurality of chip modules to be sequentially powered on according to a preset power-on time sequence.
In the embodiment of the invention, the power-on time sequence is set according to the characteristics of a plurality of chip modules in the domain controller.
The power-on and power-off control method of the domain controller is suitable for the control module, the control module is a control module of the domain controller, and the control module can control a plurality of chip modules to work. In particular, the control module may be a microcontroller module in the domain controller, i.e. an MCU of the domain controller.
In the power-on and power-off control method of the domain controller, the signal state of the wake-up signal is detected by the control module, the power supply module is controlled to supply power to the control module under the condition that the signal state of the wake-up signal meets a first preset condition so as to enable the control module to be powered on and complete initialization operation, and the control module controls other modules (namely a plurality of chip modules) in the domain controller to be powered on sequentially according to a preset power-on time sequence under the condition that the control module is powered on. Therefore, the normal electrification of the domain controller is ensured by setting the power-on and power-off flow of the domain controller and controlling the power supply time sequence of other chip modules in the domain controller through the control module, so that the domain controller can be started normally.
The power supply module is used for supplying power to the control module, and the power supply module is a power supply module in the domain controller, or the power supply module is arranged outside the domain controller and is connected with the control module through a power line so as to supply power to the control module. The position and form of the power supply module can be selected according to actual conditions, and are not particularly limited herein.
Further, the plurality of chip modules include modules such as SOC1, SOC2, PCIE, LANSwitch, FPGA, and the like.

That is, the MCU corresponds to a power supply of modules such as SOC1, SOC2, PCIE, LANSwitch, and FPGA. Namely, the control module is equivalent to the power supply of a plurality of chip modules, and the control module is powered on and powered off through other modules in a plurality of power cord control domain controllers, so that the control domain controller is wholly powered on and powered off to ensure the normal starting and closing of the domain controller.
Further, the wake-up signal is specifically a key signal, and the on-off state of the key is determined by detecting the signal state of the wake-up signal, so that each chip module is controlled to be powered on and powered off according to the on-off state of the key.
