The invention discloses an auxiliary climbing control method and climbing auxiliary system for a two-wheeled electric vehicle, wherein the method comprises the steps: detecting the inclination throughtwo inclination angle sensors, calculating a theoretical torque according to the opening degree of a rotating handle, and detecting the pressure borne by a rear wheel through a pressure sensor; calculating the rear wheel load and the theoretical rotating speed; and detecting the actual rotating speed of the rear wheel through a rotating speed sensor, judging whether the climbing auxiliary function is started or not by comparing the actual rotating speed with the theoretical rotating speed, and finally, calculating auxiliary torque through an ECU controller, and controlling an auxiliary motorto provide the auxiliary torque. The climbing auxiliary system comprises the ECU controller and a display instrument panel. The ECU controller is connected with a first inclination angle sensor, a second inclination angle sensor, the pressure sensor and the rotating speed sensor. A hub motor is connected into a rear wheel of the electric vehicle, and an auxiliary motor is connected to the hub motor through a belt wheel and a synchronous belt. When used in the two-wheeled electric vehicle, the climbing auxiliary system not only can improve the driving feeling during climbing, but also has the advantages of good driving safety and convenience in use.
