Abstract
In a method for setting a specifiable target speed in a motor vehicle with an internal combustion engine, actuating signals for the manipulation of the throttle valve of the internal combustion engine are produced in a speed-regulating system taking into account vehicle-state and operating variables. To improve controller behaviour in partial shut-down operation, the controller output of the regulating system is passed via a metering characteristic to produce the actuating signal which manipulates the position of the throttle valve, both full operation and partial shut-down operation being assigned a respective metering characteristic. At the time of the switchover between full operation and partial shut-down operation, the controller output is first of all passed via the metering characteristic assigned to operation hitherto and then via an inverse metering characteristic assigned to subsequent operation.
