Abstract
A method for automatically controlling the speed of a ship, in which the engine speed (nMOT) is automatically controlled by a closed-loop engine speed control system as an inner closed-loop control system, the ship's speed (vS) is automatically controlled by a closed-loop ship's speed control system as an outer closed-loop control system, and the ship's set speed (vSL) is influenced as a reference input of the closed-loop ship's speed control system as a function of an external signal source. The ship's set speed (vSL) is corrected as a function of the underwater topography (TOPO).
Claims7
A method for automatically controlling speed of a ship, comprising the steps of:
- automatically controlling engine speed (nMOT) by a closed-loop engine speed control system as an inner closed-loop control system;
- automatically controlling the ship's speed (vS) by a closed-loop ship's speed control system as an outer closed-loop control system;
- influencing the ship's set speed (vSL) as a reference input of the closed-loop ship's speed control system as a function of an external signal source;
- determining underwater topography (TOPO) using an electronic river chart;
- and
- correcting the ship's set speed (vSL) predictively as a function of the underwater topography (TOPO).
