The invention provides an unmanned vehicle track estimation method and system, computer equipment and a storage medium, and belongs to the field of unmanned vehicle system simulation and estimation, and the method comprises the steps: initializing the related parameters of an unmanned vehicle, and enabling the parameters to meet the ellipsoid constraint conditions; and setting the maximum simulation time length, and determining an estimator gain matrix at the kth moment by utilizing an optimization problem based on related parameters. And constructing a dynamic model of the unmanned vehicle system at the (k + 1) th moment, and obtaining a non-fragile ellipsoid set membership estimator at the (k + 1) th moment together with the gain matrix. And related parameters at the (k + 1) th moment are obtained through non-fragile ellipsoid set membership estimation at the (k + 1) th moment, and the non-fragile ellipsoid set membership estimator is iteratively updated according to a judgment condition, so that the track estimation accuracy of the unmanned vehicle is improved.
