The embodiment of the invention provides a torque filtering method, a torque filtering device and a vehicle. The torque filtering method comprises the steps that current operation parameters of the vehicle are acquired; determining a current request torque, a torque filtering coefficient and a filtering time constant of the vehicle based on the current operation parameters of the vehicle; obtaining an initial torque change amplitude based on the current request torque and the target request torque of the previous sampling period; correcting the initial torque change amplitude based on the torque filter coefficient and the filter time constant to obtain a corrected torque change amplitude; and obtaining a request torque after primary filtering based on the target request torque and the corrected torque change amplitude of the previous sampling period.
