A method for controlling the idle speed in a hybrid vehicle in which at least two power plants contribute together or separately to driving the hybrid vehicle, and a setpoint value is compared to an actual value for controlling the idle speed, the setpoint rotational speed being set as a function of the comparison by changing at least one intensification factor of the control. To adapt the control dynamics to the actual transmission characteristics of the first of the two power plants, the idle speed control for the at least two power plants is carried out simultaneously, the at least one intensification factor being continuously adapted to the power output of a first of the two power plants.
