DETAILED DESCRIPTION

[0030] With the continuous development of automobile electrification, intelligence, networking and sharing (new four), there are mainly the following problems: first, the number of sensors and actuators on the car is growing rapidly, and direct interaction between sensors, actuators and central computing unit through hardwire will lead to too complex car wiring harness; second, the central computing unit is responsible for the signal collection of the vehicle sensors and the on-demand control of the actuators, and the complex collection and driving circuit will make the central computing unit become very large, which is not conducive to the vehicle layout; third, the vehicle interaction signal increases significantly, and the interaction frequency rises straight up, which brings great challenges to the design of the communication architecture. Therefore, the vehicle logic algorithm of each host factory is moved to the central computing unit, the sensor needs to process the vehicle state information simply, and then send it to the central computing unit through CAN bus (Controller Area Network) / CANFD bus (CAN with Flexible Data rate) / optical fiber and other communication methods for deep decision-making, and finally the decision result is sent to the actuator through CAN bus / CANFD bus / optical fiber and other communication methods, therefore, under this new electronic and electrical architecture, the sensor and the actuator are required to have simple signal processing capability, and this new sensor and actuator is called intelligent sensor and intelligent actuator. The birth of this intelligent sensor and intelligent actuator will simplify the vehicle wiring harness into power line, ground line, CAN / CANFD line and optical fiber. In order to further reduce the cost of vehicle wiring harness, the vehicle is divided into several regions, and the intelligent actuators and intelligent sensors in each region access the regional control device through CAN bus / CANFD bus / optical fiber, and each regional control device interacts with the central computing unit through optical fiber. This "central computing + regional control" electronic and electrical architecture not only improves the vehicle communication rate, but also greatly reduces the cost of wiring harness. At the same time, optical fiber communication has the characteristics of high speed, low power consumption and energy saving, and can effectively avoid the interference of complex electromagnetic environment inside and outside the vehicle to the vehicle signal, thereby effectively protecting the safety of system data, therefore, optical fiber communication has become an inevitable demand for the continuous development of the new four of automobile.

[0031] Based on the above demand of new centralized electronic and electrical architecture, the regional control device not only needs to be responsible for the communication transmission between the intelligent sensors and intelligent actuators in the region and the central computing unit, but also needs to supply power to the intelligent sensors and intelligent actuators in the region.
