Although it has suppressed the impact of road attachment disturbances in the environment, it has not comprehensively considered the road attachment disturbances in physical space and the delay disturbances in network space. As the electronic and electrical architecture of automobiles becomes more and more perfect and complex, it is still Unable to achieve ideal automatic emergency braking effect under the influence of network delay disturbance in the system

The invention relates to the technical field of automatic emergency braking of electric vehicles, in particular to an electric vehicle cyber-physical fusion automatic emergency braking control system and a design method. Hierarchical structure of emergency braking strategy system. Taking road adhesion changes and network-induced delay disturbances as examples, the disturbances in physical space and information space during automatic emergency braking are estimated and suppressed to reduce their impact on automatic emergency braking performance, thereby improving automatic emergency braking. The real-time performance, security and stability of the process. The invention also provides a system design method, which is divided into two steps of multi-disturbance estimation and multi-disturbance suppression, and for the problem of network-induced delay disturbance processing in network systems, two steps of delay analysis and delay robust control algorithm are proposed, A reliable methodology is provided for the disturbance handling problem of the automatic emergency braking system.
Description
technical field [0001] The invention relates to the technical field of automatic emergency braking of electric vehicles, in particular to an electric vehicle information-physical fusion automatic emergency braking control system and a design method.
