According to the method, torque reconstruction and feedback control are carried out on a motor torque demand obtained by an energy management strategy, and the self-adaptive adjusting torque is obtained together with optimal control parameters output by a constructed working condition control parameter library obtained by off-line optimization of control parameters; and after interference adaptive compensation is carried out, the total target torque of the motor is obtained and output to the controlled hybrid power vehicle. According to the method provided by the invention, control parameters can be automatically adjusted according to working condition changes, the motor control effect is improved, and meanwhile, an interference adaptive compensation algorithm is utilized, so that the anti-interference capability of a torque reconstruction and feedback control algorithm is improved to a certain extent.
