A locomotive and a weighted parameter adhesion control method therefor. The method comprises: according to an operation state of a locomotive, acquiring a traction electric motor torque given value and a weighted adhesion control reference value, to generate a traction electric motor torque given control value; calculating a weighted adhesion control feedback value; performing calculation, in a weighted adhesion control PI closed-loop controller, with the weighted adhesion control reference value and the weighted adhesion control feedback value, so as to obtain a weighted adhesion control value; controlling the torque of a traction electric motor according to the smaller of the weighted adhesion control value and the traction electric motor torque given control value; and from a moment T0, filtering the traction electric motor torque given value according to m*G(S) until the traction electric motor torque given control value is recovered to a% of the maximum torque value of the traction electric motor, and then carrying out filtering processing on the traction electric motor torque given value according to G(S)/n. According to the method, the adhesion force of the locomotive is exerted to the maximum extent, and traction idling or braking coasting is effectively prevented, such that the locomotive exerts the maximum traction force or braking force under the current rail surface condition.
