Design and Simulation Analysis for Integrated Vehicle Chassis-Network Control System Based on CAN Network

Abstract EN

Due to the different functions of the system used in the vehicle chassis control, the hierarchical control strategy also leads to many kinds of the network topology structure.

According to the hierarchical control principle, this research puts forward the integrated control strategy of the chassis based on supervision mechanism.

The purpose is to consider how the integrated control architecture affects the control performance of the system after the intervention of CAN network.

Based on the principle of hierarchical control and fuzzy control, a fuzzy controller is designed, which is used to monitor and coordinate the ESP, AFS, and ARS.

And the IVC system is constructed with the upper supervisory controller and three subcontrol systems on the Simulink platform.

The network topology structure of IVC is proposed, and the IVC communication matrix based on CAN network communication is designed.

With the common sensors and the subcontrollers as the CAN network independent nodes, the network induced delay and packet loss rate on the system control performance are studied by simulation.

The results show that the simulation method can be used for designing the communication network of the vehicle.
