Abstract
A control unit and a method for influencing the speed of an engine and the slip of a downstream clutch of a transmission of a ship's propulsion system via an electronic control unit in response to a manual control-signal generator to select the sense of rotation and the driving speed, wherein, as the clutch is engaged to initiate forward or reverse driving, a slip determination unit of the electronic control unit influences the slip of the clutch in response to a ramp function characteristic to reduce the clutch's slip during an engagement period.
Claims8
A control apparatus for influencing the speed of an engine, and the slip of a downstream clutch of a transmission of a ship's propulsion system via an electronic control unit in response to a manual control-signal generator to select the sense of rotation and the driving speed,
- wherein during engagement of the clutch for initiating forward or reverse driving, a slip determination unit of the electronic control unit influences the slip of the clutch in response to a ramp function characteristic to reduce the clutch slip(s) during an engagement period;
- and
- wherein the electronic control unit feeds a cruise command given by the manual control-signal generator in a split manner to a first converter unit for characteristic-controlled determination of an engine speed signal for the downstream engine, and to a second converter unit for characteristic-controlled determination of a sense-of-rotation signal for the downstream transmission.
A method for influencing the speed of an engine, and the slip of a downstream clutch of a transmission of a ship's propulsion system via an electronic control unit in response to a manual control-signal generator to select the sense of rotation and the driving speed,
- wherein as the clutch is engaged for initiating forward or reverse driving, the clutch's slip is influenced in response to a ramp function characteristic to reduce the clutch's slip along the engagement path by a slip determination unit of the electronic control unit;
- and
- wherein, by the electronic control unit, a cruise command given by the manual control-signal generator is fed to a first converter unit for characteristic-controlled determination of an engine speed signal for the downstream engine, and to a second converter unit for characteristic-controlled determination of a sense-of-rotation signal for downstream switching of the transmission.
