Abstract

The invention discloses a distributed domain controller system based on the network architecture of an automatic driving system. The system is provided with a central domain calculation control unit including a central domain calculation control sub unit and a vehicle Ethernet switch domain unit, wherein the central domain calculation control sub unit is connected with the vehicle Ethernet switchdomain unit in a vehicle Ethernet mode, the system is provided with a vehicle control unit including a central gateway unit, a power domain control unit, a chassis domain control unit, a vehicle bodycontrol domain unit and an electronic cabin unit, the different-function units are connected with the central gateway unit through controlling a local area network CAN bus, and the central gateway unit is connected with the vehicle Ethernet switch domain unit in a vehicle Ethernet mode. The system is advantaged in that flexibility of overall configuration, efficiency of data calculation and command execution under different dedicated functional units, and convenience of fault and abnormality handling and component replacement can be improved.

Description

technical field [0001] The present application relates to the technical field of automatic driving, in particular to a distributed domain controller system based on the network architecture of the automatic driving system. Background technique [0002] With the improvement of autonomous driving technology and the increase of vehicle functions, the amount of various types of data generated by the vehicle itself is also increasing, especially in Level 3 and Level 4 vehicles that can achieve a higher degree of autonomous driving. more obvious. For these data, it is usually processed by the domain controller system of the network architecture in the vehicle. [0003] At present, the domain controller system of the network architecture in the self-driving vehicle is usually a central type or a centralized hybrid type. function to process the data generated by the corresponding type of sensor. However, concentrating multiple functions on one domain controller will result in inf...
