The embodiment of the invention discloses a vehicle control method, system and device based on trajectory tracking, equipment and a storage medium. The method comprises the following steps: acquiring driving data and reference trajectory related data of a vehicle at the current moment; determining an initial front wheel steering angle according to the driving data and the reference trajectory related data; determining a front wheel steering angle compensation amount according to the expected transverse displacement and the actual transverse displacement; a target front wheel turning angle is determined according to the initial front wheel turning angle and the front wheel turning angle compensation amount, and the vehicle is controlled to run along the reference track according to the target front wheel turning angle. The target front wheel turning angle is obtained based on the initial front wheel turning angle and the front wheel turning angle compensation amount, the vehicle is controlled to run along the reference trajectory according to the target front wheel turning angle, trajectory tracking precision can be improved, and the problems that traditional model prediction control trajectory tracking is not high in precision and not high in robustness are solved.
