ABSTRACT:
A method for operating a drive unit, in which, given the use of a vehicle-speed controller, the actual speed is prevented from exceeding the setpoint speed too significantly. In the method, a setpoint value for an output variable of the drive unit is predetermined. An overrun fuel cutoff of the drive unit is enabled as soon as the setpoint value for the output variable falls below a characteristic value for the overrun fuel cutoff.
