Application of Inductive Sensors in Trajectory Control of Autonomous Vehicles
Autonomous vehicles need to accurately perceive the surrounding environment,including roads,obstacles,traffic signs,pedestrians,etc.Controlling the trajectory of autonomous vehicles can reduce accidents caused by human driving errors and fatigue driving,and improve driving safety.Therefore,the application of induction sensors in trajectory control of autonomous vehicles is proposed.A two-degrees-of-freedom model for autonomous vehicles is constructed.The inclination angles of the front and rear wheels of the vehicle are calculated.And the vehicle motion calculation formula is obtained.The safe distance of the vehicle is calculated based on the sensing sensor's perception of blind spots;a smaller edge line acceleration is taken,and the optimal following safety range is determined.Using the proportional integral differential(PID)feedback control method,the angle and forward speed of the vehicle are controlled and adjusted through feedback,achieving precise trajectory control.The experimental results show that the induction sensor can clearly perceive the trajectory of unmanned vehicles.The control performance is good with small errors,ensuring the safe and stable operation of the vehicle.
