Abstract
A marine maneuvering system for a marine vessel is provided. The marine maneuvering system comprises a marine vessel control unit configured to: obtain a requested movement of a joystick indicating a speed value and a direction value for an upcoming navigation of the marine vessel; obtain proximity signals from a proximity sensor in response to a target being sensed in at least portions of an environment surrounding the marine vessel at least towards a direction indicated by a direction value of the joystick; determine a distance between the marine vessel and the target based on the proximity signals; and control a force feedback device to apply a force feedback to the joystick based on the determined distance.
Claims18
A marine maneuvering system for a marine vessel, comprising:
- a proximity sensor configured to sense at least portions of an environment surrounding the marine vessel;
- an input device adapted to provide navigational commands to the marine vessel, wherein the input device comprises a movable joystick and a force feedback device being adapted to apply a force feedback to the joystick;
- and
- a marine vessel control unit operatively connected to the proximity sensor and the input device, the marine vessel control unit being configured to:
- obtain a requested movement of the joystick, the requested movement indicating a speed value and a direction value for an upcoming navigation of the marine vessel;
- obtain one or more proximity signals from the proximity sensor in response to at least one target being sensed in the environment at least towards a direction indicated by the direction value;
- determine a distance between the marine vessel and the at least one target based on the one or more proximity signals;
- and
- control the force feedback device to apply a force feedback to the joystick based on the determined distance by:
- calculating a maximum allowed speed for the marine vessel based on the determined distance;
- translating the maximum allowed speed into a maximum allowed joystick movement;
- and
- limiting the requested movement of the joystick based on the maximum allowed joystick movement.
A computer-implemented method for a marine vessel, comprising:
- obtaining a requested movement of a joystick, the requested movement indicating a speed value and a direction value for an upcoming navigation of a marine vessel;
- obtaining one or more proximity signals from a proximity sensor in response to at least one target being sensed in the environment at least towards a direction indicated by the direction value;
- determining a distance between the marine vessel and the at least one target based on the one or more proximity signals;
- and
- controlling a force feedback device to apply a force feedback to the joystick based on the determined distance by:
- calculating a maximum allowed speed for the marine vessel based on the determined distance;
- translating the maximum allowed speed into a maximum allowed joystick movement;
- and
- limiting the requested movement of the joystick based on the maximum allowed joystick movement.
