An intelligent vehicle chassis coordinated control system and method based on driving state recognition

Abstract

The application discloses a kind of intelligent vehicle chassis coordination control system and method based on driving state identification, mainly through hidden Markov model to the classification of driving state, further subdivides driving state by extension theory, and determines the weight coefficient of active front wheel steering control system and direct yaw moment control system based on current driving state, the output of two chassis subsystems is weighted distribution, realizes the coordination control of two chassis subsystems.It ensures that both chassis subsystems can maximize the corresponding advantages, while trying to avoid the disadvantages of two chassis subsystems.According to the simulation results in this paper, the coordination control system proposed in the application has good control effect on vehicle yaw rate and speed.It can reduce speed fluctuations while ensuring safe driving of the vehicle and ensure the comfort of passengers in the vehicle.
