Abstract:
The invention relates to a method, operator guiding device and computer program product for guiding a vessel operator among obstacles. The device is provided for a bridge (13) of a vessel, which bridge has a manoeuvring position and the vessel has a reference manoeuvring direction and a vessel position, and comprises a vessel steering unit (26), a group of loudspeakers (28, 30, 32, 34) and a navigation control computer, where the navigation control computer obtains obstacle proximity data of at least one obstacle at an obstacle position relating to the vessel position, which obstacle proximity data at least comprises the angle between the obstacle position and the reference manoeuvring direction, determines a presentation position based on the obstacle proximity data and presents the obstacle through generating sound and controlling the group of loudspeakers (28, 30, 32, 34) to make the sound appear to come from the presentation position.
Abstract:
A steering system for a vessel is provided. The steering system includes an electric motor assembly and a steering linkage for transmitting the rotational output of the electric motor assembly to the vessel's rudder. The steering system may include at least three linkage members. The steering system may provide a variable output torque that corresponds at least partially with the variable required torque of the rudder at different rudder angles. The steering system may partially decouple the electric motor assembly from vertical movements in the rudder. Embodiments may include additional motor assemblies and steering linkages. The additional motor assemblies and steering linkages may provide an opposing force to reduce flutter within the system and/or be used to reduce the load of any one electric motor assembly.

Un systeme de direction possede un appareil de commande sensible ameliore. Un materiau plastique, de preference un film de fluorure de polyvinylidene (PVDF), rendu hautement piezoelectrique par des procedes connus, est place dans une structure d'une unite detectrice (94) ou une pression est exercee contre le film piezoelectrique (140) par la rotation de la roue de direction (12) du bateau (10) ou du vehicule de maniere telle que le film piezoelectrique (140) genere des signaux electriques qui sont utilises pour commander les tours/minute d'un moteur de servo-direction reversible instantanement, de faible inertie. Les tours/minute du moteur sont sensiblement proportionnels aux signaux electriques qui, a leur tour, sont determines par et sensibles aux degres de rotation et a la vitesse de rotation de la roue de direction (12). Le sens de rotation de la roue direction (12) determine le sens de la direction assistee, soit vers la gauche soit vers la droite. Cependant, le couple disponible du moteur est sensiblement inversement proportionnel au nombre de tours/minute du moteur qui propulse le bateau (10) ou vehicule.

A steering system for a marine vessel comprises a helm, a control head, and a joystick. The helm and control head may respectively provide user inputted steering commands and user inputted shift and throttle commands on a first CAN network. The joystick and the control head may respectively provide user inputted steering commands and user inputted shift and throttle commands on a second CAN network. The helm may provide user inputted steering commands on the first CAN network. The control head may provide user inputted shift and throttle commands on the second CAN network. The joystick may provide user inputted steering commands and user inputted shift and throttle commands on either the first CAN network or the second CAN network.

Abstract:
The invention relates to a steering unit (1) for a steer-by-wire ship's control system, comprising a control rudder (3), a controller (11) that is connected to the electronic controller of the ship's control system (ECU) via a CAN bus, a sensor (10) for detecting the angular position of the control rudder (3) and a unit for generating mechanical resistance in the control rudder (3). In said steering unit, the unit for generating mechanical resistance in the control rudder (3) is designed as an electric motor (8) and the shaft (2) of the control rudder (3) that is rotationally fixed to said control rudder (3) is rotationally fixed to the rotor (7) of the electric motor (6) and the stator (8) of the electric motor (6) is rotationally fixed to the housing (5) of the electric motor (6).
Abstract:
The present invention relates to a propeller drive arrangement and a method for moving and steering a vessel. The arrangement comprises an azimuthing propulsion unit (6) and operating equipment for turning said azimuthing propulsion unit to steer the vessel. The operating equipment comprises an electric motor (20) for rotating said propulsion unit (6) by means of a mechanical power transmission machinery (40) connected to said electric motor. A power unit (30) supplies electric power to said electric motor (20). A control unit (34) controls the operation of said electric motor by controlling said power unit (30). The arrangement also comprises a sensor device (16) for detecting the rotational position of said azimuthing propulsion unit (6). A control unit (34) is arranged to process steering command information from a control means (38) and turning position information from said sensor device (16) and to control the operation of said electric motor (20) on the basis of this processing.
Abstract:
A steering system for vehicles or ships is provided, with a steering handwheel (11) and a steering element (1) with no mechanical linkage line therebetween, with a steering handwheel sensor device (14, 15), a steering element sensor device (16, 17) and a control arrangement (61, 62) which, in dependence on the output signals of the sensor devices (14-19), operates an electromechanical transducer (2, 3, 4, 5), on the output side of which the steering element (1) is arranged. It is desirable to increase the reliability of such a steering system. For that purpose, the control arrangement comprises at least two independent control units (61, 62), and a fault-monitoring device (28, 38) is provided which precludes a defective control unit from influencing the steering element.
