The invention provides an intelligent vehicle, a path tracking control method and device thereof and a storage medium. The control method comprises the following steps: building a three-degree-of-freedom vehicle dynamics model; building a magic formula tire model; an MPC is selected as a benchmark, and a vehicle transverse control algorithm is designed; designing a vehicle longitudinal control algorithm by taking double PID control as a benchmark; coupling the vehicle transverse control algorithm and the vehicle longitudinal control algorithm, determining a transverse and longitudinal control algorithm, and controlling the vehicle according to the transverse and longitudinal control algorithm. The problem solved by the invention is that the performance and transverse and longitudinal decoupling of a model prediction controller in related technologies cannot accurately describe the vehicle driving state.
