The PDUR Router module functions of the entire VDC include unicast, multicast, gateway 1-to-many, many-to-one, and many-to-many routing module functions. During this period, PDUR Router needs to implement PDU receiving from the local module (I-PDU is received and sent from the lower layer to the upper layer), PDU is transmitted from the local module (I-PDU is received and sent from the upper layer to the lower layer), PDU gateway (from the interface module and the transmission protocol module) Receive I-PDU and transmit to other communication interface modules) these three functions. Thereby ensuring the validity of the routing function.
For the domain control of the whole vehicle, it is usually used as a low-level version of the intelligent driving domain control in the design process, or some models directly transplant the low-end or sub-low-end intelligent driving function to the whole vehicle when doing configuration analysis Carry out in domain control. At this time, the vehicle domain control is equivalent to a base version of the integrated parking controller, which needs to undertake some low-level driving and parking control functions. Therefore, when implanting chip units with different processing capabilities in the VDC, try to choose super-heterogeneous chips with integrated computing capabilities. It can not only meet the perception needs of driving functions, but also meet the needs of parking perception capabilities. The integrated ultra-heterogeneous chip with medium computing power recommended here.
