【Abstract】To address the issue of limited path tracking abilityof Ultra-thin Carier Robot (UCR)in complex test scenariosin inteligentconnectedvehicletesting,thispaperproposesanimproved Stanleylateral motioncontrolalgorithm. Firstly,the kinematicmodelofthe UCRisestablishedbasedontheAckermannstering principle,ndthebicyclemodel is used tosimplifythesteeringsystemoftheUCR.Then,afuzzyPIDcontrolerisintroducedonthebasisof the traditional Stanleyalgorithminorder toenhancetheadaptivefeedbackcapabilityof thealgorithm.Theresultsof thejointsimulationof CarSim and MATLAB/Simulink show that the modified Stanleyalgorithm reduces the average lateral error by 50.67%and the maximumlateralerorby41.76%atdiferentspeedscomparedwiththetraditionalalgorithm.Thereal-vehicletestfurther confirmsthattheimprovedalgorithmperforms wellinmediumand high-speed straightlineandlanechanging scenarios,with theaveragelateral errorlessthanO.O5mand the maximumlateralerorlessthanO.17m.It meets thetestingrequirementsof intellgentconnectedvehiclesindiferentscenariosandrealizeshigh-speedand high-precisionlateralmotioncontrolf the UCR.
