Abstract:
1. A boat, comprising: A first and a second driveline, each of which comprises a propulsion unit and a servo device for a direction-of-travel-setting device; a control system for the boat, wherein the control system comprises: wherein the first hierarchical control module receives and processes the speed or acceleration command signals and the steering command signals and generates and outputs speed or acceleration control signals and steering control signals corresponding to the speed or acceleration command signals and the steering command signals, respectively; wherein the second hierarchical control module associated with each driveline is configured to execute operating routines for the propulsion unit of the driveline, which operating routines generate operating signals for the propulsion unit of the driveline in response to target value signals generated externally to said second hierarchical control module associated with the driveline; and wherein the third hierarchical control module associated with each driveline receives and processes the speed or acceleration control signals and the steering control signals output by the first hierarchical control module and, in response to conditions corresponding to driving characteristics of the boat, converts those speed or acceleration control signals and steering control signals into said target value signals for the driveline with which the third hierarchical control module is associated.
