The invention discloses a vehicle driving trajectory tracking method, a control system, a vehicle and a storage medium. The method comprises the following steps: acquiring planning information and positioning information; determining a longitudinal control quantity and a lateral control quantity based on the planning information and the positioning information; determining a target acceleration based on the longitudinal control quantity; determining a target steering wheel angle based on the lateral control amount; determining a first steering wheel torque based on the target steering wheel angle and an observed quantity, the observed quantity including a disturbance observed quantity; and working according to the target acceleration and the first steering wheel torque. Under the control of the target acceleration and the first steering wheel torque, the vehicle can perform tracking driving according to the planned path. Besides, after the first steering wheel torque is compensated and corrected through the disturbance observed quantity, when the vehicle works according to the first steering wheel torque, interference of noise to a control system can be reduced, and the tracking precision of the planned path is improved.
