Abstract
In a method of controlling a drive unit, particularly an internal-combustion engine generator unit, in addition to first and second controlling devices, a third controlling device is provided for computing a third injection quantity. One of the controlling devices is set as dominant for controlling the rotational speed. From an operator determined charge definition, a charge injection quantity is computed, and is compared with the injection quantity of the dominant controlling device. As a function of the comparison, the dominance of the controlling device is retained or the charge definition is set to be dominant for a power-determining signal.
Claims18
A method of controlling the rotational speed of a drive unit, comprising:
- a first controlling device computing a first injection quantity;
- a second controlling device computing a second injection quantity;
- a third controlling device computing a third injection quantity;
- setting one of said controlling devices to be dominant, said dominant controlling device controlling the rotational speed;
- deactivating controlling devices that are not dominant;
- determining a charge injection quantity from a charge definition;
- comparing an injection quantity of the dominant controlling device with the charge injection quantity;
- and
- as a function of the comparison, retaining the dominance of the dominant controlling device or setting the charge definition to be dominant for a power-determining signal.
