The invention discloses a method and a system for controlling the driving tension of a working rotor belt of a pavement cold recycling machine. The method and the system can automatically adjust the driving tension of a driving belt according to working condition requirements. The method comprises the steps of equipment debugging, power mode selection, working mode selection, thrust calculation of a tensioning device, tensioning device adjustment, mode switching, shutdown and the like. The control system comprises a driving wheel, a driven wheel, a transmission belt, a working rotor, a power system and a tensioning device, the tensioning device acts on the loose edge side of the transmission belt between the driving wheel and the driven wheel, and the controller assembly comprises an engine controller, an operation mode controller, an ECU controller and a thrust controller. And the ECU controller controls the tensioning device through the thrust controller to provide and maintain the thrust value to the loose
