Establishment and research of state model of intelligent vehiclebend system based on kalman filter

摘要

In view of the problems of route selection and driving stability of intelligent vehicle in the process of turning,a state model of intelligent vehicle turning system control based on Kalman filter is proposed.Taking intelligent vehicle as the research object,according to the route of intelligent vehicle passing through a certain bend at uniform speed,the corresponding state transition model of intelligent vehicle's speed and position is established,and the state model of intelligent vehicle's bend system is analyzed,and the system state equation of intelligent vehicle in the process of bend movement based on Kalman filter is obtained.According to the state equation of the system,it can effectively monitor the speed,position and trajectory of the intelligent vehicle on the bend.Combining with Kalman filter algorithm,it can effectively reduce the noise of the control process and observation noise.It can be used to achieve more stable and accurate control of the intelligent vehicle in the bend movement.
