Design of Lane Change Control System for Autonomous Electric Vehicle Based on Sine Function
Due to the uncertainty of traffic road environments,in order to effectively control lane changing behaviors,a lane chan-ging control system for autonomous electric vehicles based on a sine function is studied.The power signal input from the sinusoidal three-phase inverter control power supply is used to drive the simulation platform and information communication encoder of the lane changes,and design the application components of the lane changing control system for an autonomous driving electric vehicle at all levels.The key lane changing segments are selected to extract the starting and ending lane changing positions,construct the potential field of the lane centerline,define the specific lane changing trajectory clusters,and generate the electric vehicle lane changing trajec-tory clusters required by the control.Acoording to the calculation results of safety lane changing distance based on the sine function,the feedback controller closed-loop is constructed,and the model is used to control and plan the lane changing trajectories,achieve the vehicle lane changing behavior control based on the sine function.The various application structures are combined to complete the de-sign of the autonomous driving electric vehicle lane changing control system.The experimental results show that the above system does not cause collisions in autonomous electric vehicles due to delayed lane changing,and can accurately identify the obstacles on the road,improving driving safety.The design and implementation of this system provide useful reference and inspiration for the develop-ment and application of autonomous electric vehicles.
