The invention provides an intelligent automobile information flow safety redundancy 
control system based on a 
chassis domain controller. The 
chassis domain controller realizes interaction with external information flow through a redundancy 
signal channel, and the redundancy 
signal channel comprises a transverse cooperative 
control unit, a longitudinal cooperative 
control unit, a safety redundancy unit and diagnosis / fault redundancy, wherein the transverse cooperative 
control unit, the longitudinal cooperative control unit and the safety redundancy unit are directly linked to a main control 
chip of a core operation unit. According to the 
system, information flow on a 
chassis is re-integrated based on the concept of chassis dynamics domain control, meanwhile, a redundant 
interaction interface of chassis information and intelligent driving related information is re-defined for a future intelligent automobile framework, and through a high-reliability 
domain controller and a redundant safety information flow channel, and by combining 
encryption and 
verification technologies, redundant control of each execution mechanism of the chassis is realized, hierarchical management and 
signal verification of an automatic driving function module, redundant control of a whole vehicle signal and whole vehicle information flow 
verification work are realized, and the information safety of the whole vehicle is ensured.
