The invention discloses a torque estimation method and device, a vehicle, a storage medium and a product, and relates to the technical field of motor control, and the method comprises the steps: obtaining real-time operation parameters of a target motor, and constructing a target feature vector based on the real-time operation parameters; the target feature vector is input into a target width learning model, the estimated output torque of the target motor under the real-time operation parameters is obtained, and the target width learning model takes the feature vector constructed on the basis of the operation parameters of the motor at one moment as model input data to obtain the estimated output torque of the target motor under the real-time operation parameters. Label data constructed based on the real output torque of the motor at the moment is used as a model to train labels. The accuracy of motor output torque estimation can be improved.
