Research on Coordinated Control of the Vehicle Chassis System Based on a Hybrid Model

Abstract:

Based on the analysis of the movement relationship among systems such as the chassis suspension and the steering and braking system, simulation and testing are carried out on control system of the vehicle chassis system with a coordinated control method of the hybrid model. For the complex vehicle chassis system, modeling and simulation focuses on the movement effects of the three subsystems, classifying complex under different conditions by control methods and testing control parameters separately. Based on the simulation results of the vehicle and the parameters of the controllers, software & hardware systems of the vehicle are designed, and the tests of the vehicle chassis system are carried out based on the hybrid model. The results indicate that under complicated conditions, control systems with the hybrid model can effectively improve the ride comfort, handling, and security.
