The invention discloses a locomotive and a weighted parameter adhesion control method thereof, comprising the following steps: acquiring a traction motor torque given value and a weighted adhesion control reference value according to the running state of the locomotive, and generating a traction motor torque given control value; calculating a weighted adhesion control feedback value; calculating the weighted adhesion control reference value and the weighted adhesion control feedback value in a weighted adhesion control PI closed-loop controller to obtain a weighted adhesion control value; controlling the torque of the traction motor according to the smaller one of the weighted adhesion control value and the traction motor torque given control value; filtering the traction motor torque given control value according to m * G (S) from the moment T0 until the traction motor torque given control value is recovered to a% of the maximum torque value of the traction motor, and filtering the traction motor torque give
