Estimating the term…
The invention concerns a control system for operating a drive assembly of a ship. The system consists of an engine (1), a transmission (3) and an adjustable clutch (4) for forward and reverse motions. A control station (15), a control lever (27) and a control electronics (15) are provided for adjusting the direction of motion and the speed of the ship. In order to influence the reaction of the ship when changing direction, several reversing aids are provided according to the invention. The pilot can use the reversing aids by actuating a selection key (24) located on the control station.
A control system for operating a drive assembly of a ship having at least one engine (1) which, via a transmission (3) with at least one adjustable clutch (4) for forward movement and one adjustable clutch (5) for reverse movement, drives a propeller shaft (6), sensor means for sensing at least propeller shaft speed and engine output speed, control means (5, 8, 9, 10, 11, 12, 16, 17, 27) for controlling engine speed and slipping degree of said clutch (4), at least one control station (15) with control means (18-26) having at least one steering lever (27), for adjusting travel direction and speed of the ship by actuating said steering lever and control means (12) for processing signals input from said control station and said sensor means and outputting signals to said control means for controlling engine speed and slipping degree of said clutch (4), said system comprises at least one reversing sequence for selectively engaging and reversing a travel direction of said ship during operation of said system in a low gear trolling mode of said drive assembly:
A control system for operating a drive assembly of a ship having at least one engine (1) which, via a transmission (3) with at least one adjustable clutch (4) for forward and reverse movements, drives a propeller shaft (6), control and sensor means (5, 8, 9, 10, 11, 12, 16, 17, 27) for controlling at least one of engine speed and slipping degree of said clutch (4), at least one control station (15) with control means (18-26) for adjusting travel direction and speed of the ship by actuating at least one steering lever (27) and control electronics (12) for processing input and output signals, characterized in that during operation in a low gear trolling mode of said drive assembly, said clutch (4) becomes completely closed after engaging a travel direction and an acceleration phase is terminated by transmitting to said control electronics (12) a control signal which is a negative gradient adjustment of said steering lever converting said clutch (4) to a controlled slipping operation resulting in a reduction of trolling speed.
A control system for operating a drive assembly of a ship having at least one engine (1) which, via a transmission (3) with at least one adjustable clutch (4) for forward and reverse movements, drives a propeller shaft (6), control and sensor means (5, 8, 9, 10, 11, 12, 16, 17, 27) for controlling at least one of engine speed and slipping degree of said clutch (4), at least one control station (15) with control means (18-26) for adjusting travel direction and speed of the ship by actuating at least one steering lever (27) and control electronics (12) for processing input and output signals, characterized in that during operation in a low gear, trolling mode of said drive assembly, said clutch (4) becomes completely closed after engagement of the travel direction, and the acceleration phase is terminated by transmitting to said control electronics (12) a control signal which indicates that a defined speed of the ship has been reached thereby adjusting the speed of said propeller shaft (6) to a trolling speed.
A control system for operating a drive assembly of a ship having at least one engine (1) which, via a transmission (3) with at least one adjustable clutch (4) for forward and reverse movements, drives a propeller shaft (6), control and sensor means (5, 8, 9, 10, 11, 12, 16, 17, 27) for controlling at least one of engine speed and slipping degree of said clutch (4), at least one control station (15) with control means (18-26) for adjusting travel direction and speed of the ship by actuating at least one steering lever (27) and control electronics (12) for processing input and output signals, characterized in that during operation in a low gear, trolling mode of the drive assembly, said clutch (4) is closed to the extent that the preselected trolling speed and direction of rotation are adjusted in said propeller shaft (6) and in a transition range where said propeller (7) acts as a turbine, said control electronics (12) keeps constant the preselected speed of the propeller shaft.
