The invention relates to an intelligent running machine. The intelligent running machine comprises a control end, a motor and a caterpillar band, wherein the control end is used for controlling the motor to work to drive the caterpillar band to move; the control end comprises a rotation speed control module used for controlling rotation speed of the motor, a pedaling frequency acquiring module used for acquiring pedaling frequency F that a user pedals the caterpillar band, a step length acquiring module used for acquiring step length D when the user pedals the caterpillar band, and a processing end connected with the rotation speed control module and the pedaling frequency acquiring module and provided with a rotation speed control algorithm; the rotation speed control algorithm is used for obtaining regulating amount V0 to regulate rotation speed of the motor; the size of the regulating amount V0 reflects rotation speed change pace of the controlled motor; when the regulating amount V0 is positive, the motor is controlled to accelerate; and when the regulating amount V0 is negative, the motor is controlled to decelerate. Data when a human body moves is counted to obtain the final pedaling results, so that stability and reliability in use are improved, and regulating efficiency is improved while safety is guaranteed.
