The invention discloses a power switching coordination control method of a coaxial parallel hybrid electric vehicle with an engine torque observer. Based on the method of a least square support vector machine, the testing sampledatum of the engine rack performance aretrained; the distribution estimation algorithm is adopted to optimize the parameter C and Lambda of the least square support vector machine; and through off-line training and optimization to an engine toque module and based on the optimum parameters, the engine torque observer is built. The current throttle value percentage and rotary speed are inputted to acquire a real-time torque value, thus realizing on-line observation to the engine torque. During the switching process of switching a pure electric driving model to a pure engine driving model (different power sources) of the vehicle provided herein, section coordination control is carried out aiming to different power sources, thus realizing stable transition of the whole switching process and stable torque of power system output without fluctuation, and satisfying the requirement of vehicle driving total torque.
