Beschreibung
Zusammenfassung:	Provided are a motor torque filtering control method and system and a hybrid electric vehicle. The motor torque filtering control method comprises: acquiring a vehicle speed in a current filtering cycle and a motor request torque distributed before filtering, and acquiring a motor output torque after filtering in a previous filtering cycle; determining a maximum filtering velocity Vmax and a minimum filtering velocity Vmin according to the motor output torque and the vehicle speed; determining an interpolation coefficient R according to the motor request torque and the vehicle speed, or according to the motor request torque, the vehicle speed, the maximum filtering velocity Vmax and the minimum filtering velocity Vmin, wherein 0≤R≤1; calculating a first filtering gradient M1 by a formula M1=R∗Vmax+(1-R)∗Vmin; and filtering the motor request torque of the motor according to the first filtering gradient M1. The solution of the present invention can ensure that a vehicle runs smoothly without impact, and improve the riding comfort of a passenger.
