The invention discloses an automatic parking trajectory tracking control method based on a linear time-varying model, and the control method comprises the steps: building a vehicle linear time-varying model based on vehicle state information; based on the target parking space information and the current position information of the vehicle, generating an ideal vehicle trajectory by using a path planning algorithm; based on the established linear time-varying model, designing a controller to control the vehicle to track a target trajectory; the designed controller is implemented, the state of the vehicle is monitored, and a control input target track is applied to the vehicle; the state and the trajectory tracking effect of the vehicle are continuously monitored, and parameters of the controller are adjusted according to the actual situation; and after the parking operation is completed, the performance and the parking effect of the system are evaluated. According to the method, the vehicle linear time-varying model is established, so that the adaptability of the automatic parking control method is higher, the calculation efficiency is higher, and when the vehicle density or the obstacle position of the parking field changes, the control system can quickly adjust.
