Device, method, and program for controlling ship body
A ship body control device is provided, which includes a control lever having a neutral position, and processing circuitry. When the control lever is moved during an automatic cruise, the processing circuitry executes a deceleration control from a speed of a ship body during the automatic cruise, and when the position of the control lever is in agreement with a position for changing to a manual cruise, the processing circuitry changes the automatic cruise to the manual cruise at a rotating speed of an engine according to the position for changing to the manual cruise.
1. A ship body control device, comprising:
a control lever having a neutral position; and
processing circuitry configured to:
execute a deceleration control from a speed of a ship body during an automatic cruise when the control lever is moved during the automatic cruise, and an amount of movement of the control lever is more than a threshold, and
change the automatic cruise to a manual cruise when a position of the control lever coincides with a position of a virtual axis corresponding to a rotating speed of an engine dropped by the deceleration control.
2. The ship body control device of claim 1 , wherein the position of the control lever for changing to the manual cruise is the neutral position.
3. The ship body control device of claim 2 , wherein a deceleration rate during the deceleration control is constant.
4. The ship body control device of claim 1 , wherein a deceleration rate during the deceleration control is constant.
5. A method of controlling a ship body, comprising:
executing a deceleration control from a speed during an automatic cruise when a control lever is moved during the automatic cruise, and an amount of movement of the control lever is more than a threshold; and
changing the automatic cruise to a manual cruise when a position of the control lever coincides with a position of a virtual axis corresponding to a rotating speed of an engine dropped by the deceleration control.
6. The method of claim 5 , wherein the position of the control lever for changing to the manual cruise is a neutral position of the control lever.
7. The method of claim 6 , wherein a deceleration rate during the deceleration control is constant.
8. The method of claim 5 , wherein a deceleration rate during the deceleration control is constant.
9. A non-transitory computer-readable recording medium storing a program causing processing circuitry of a ship body control device to execute processing, the processing circuitry configured to control operation of the device, the processing comprising:
when a control lever is moved during an automatic cruise and an amount of movement of the control lever is more than a threshold, executing a deceleration control from a speed during the automatic cruise; and
when a position of the control lever coincides with a position of a virtual axis corresponding to a rotating speed of an engine dropped by the deceleration control, changing the automatic cruise to a manual cruise.
10. The recording medium of claim 9 , wherein the position of the control lever for changing to the manual cruise is a neutral position of the control lever.
11. The recording medium of claim 10 , wherein a deceleration rate during the deceleration control is constant.
12. The recording medium of claim 9 , wherein a deceleration rate during the deceleration control is constant.
