Problems solved by technology

This consistency may be difficult to achieve when using a speed control function optimized for a single operating scenario, as operating conditions may change
[0007] Basing the control of the propulsion unit on signals internal to the propulsion unit can be a problem because it can be expensive to connect these internal signals to a control unit external to the propulsion unit.
Also, this control system then needs to be adapted to different types of propulsion systems, which can be time consuming and costly

Abstract

The present invention relates to a method for controlling a propulsion operation of a propulsion unit to reach the desired speed of a marine vessel. The method comprises obtaining a target speed configuration indicating the desired speed of the marine vessel, obtaining a current speed value associated with a current speed of the marine vessel, obtaining a fill level value associated with a fill level of one or more ballast tanks of the marine vessel, and controlling the propulsion operation of the propulsion unit to reach the desired speed based on the target speed configuration, the current speed value, and on the fill level value.

Description

technical field [0001] The present disclosure relates to the control of propulsion units (eg combustion engines and electric motors) used to power marine vessels (eg recreational craft). Background technique [0002] When operating a marine vessel, it is sometimes desirable to configure the speed of the marine vessel to be automatically achieved and maintained by the speed control function. Global Positioning System (GPS) based speed control functions are known. The user enters a desired speed into the system and the automatic speed control unit then compares the desired speed with the vessel's current speed using speed data obtained from the GPS system. The control unit then controls the propulsion operation of the ship to achieve and maintain said desired speed by adjusting the current speed to match said desired speed. [0003] Speed ​​control functions are particularly useful when implemented in power boats for wake sports such as wakeboarding, wakesurfing, wakesurfing...
