Abstract

A marine propulsion system includes a controller configured or programmed to temporarily cancel an in-wave vessel speed control mode, in which an in-wave vessel speed control is performed to adjust a vessel speed based on information regarding upward-downward movement of a hull when waves are occurring, for a predetermined period of time when an operator is operated to cancel the in-wave vessel speed control mode.

Claims (53)

1 . A marine propulsion system comprising:

a propulsion device to be provided on a hull;

a controller configured or programmed to control driving of the propulsion device to adjust a vessel speed and perform an in-wave vessel speed control to adjust the vessel speed based on information regarding upward-downward movement of the hull; and

an operator to receive an operation from a vessel user; wherein

the controller is configured or programmed to temporarily cancel an in-wave vessel speed control mode, in which the in-wave vessel speed control is performed, for a predetermined period of time when the operator is operated to cancel the in-wave vessel speed control mode.

2 . The marine propulsion system according to claim 1 , wherein the controller is configured or programmed to return to the in-wave vessel speed control mode when the predetermined period of time has elapsed.

3 . The marine propulsion system according to claim 2 , wherein the controller is configured or programmed to return to the in-wave vessel speed control mode when the predetermined period of time has elapsed and without any operation being performed on the operator.

4 . The marine propulsion system according to claim 1 , wherein

the operator includes a vessel speed adjustment operator to receive an operation to adjust the vessel speed and an operation to cancel the in-wave vessel speed control mode; and

the controller is configured or programmed to temporarily cancel the in-wave vessel speed control mode for the predetermined period of time when the vessel speed adjustment operator is operated to cancel the in-wave vessel speed control mode.

5 . The marine propulsion system according to claim 4 , wherein

the vessel speed adjustment operator includes a remote control lever assembly including a lever to receive a change in a rotational position of the lever as the operation to adjust the vessel speed, and the operation to cancel the in-wave vessel speed control mode; and

the controller is configured or programmed to temporarily cancel the in-wave vessel speed control mode for the predetermined period of time when the remote control lever assembly is operated to cancel the in-wave vessel speed control mode.

6 . The marine propulsion system according to claim 5 , wherein the controller is configured or programmed to temporarily cancel the in-wave vessel speed control mode for the predetermined period of time when the rotational position of the lever of the remote control lever assembly is changed as the operation to cancel the in-wave vessel speed control mode.

7 . The marine propulsion system according to claim 6 , wherein the controller is configured or programmed to, after temporarily canceling the in-wave vessel speed control mode, return to the in-wave vessel speed control mode with the vessel speed corresponding to the rotational position of the lever at a time at which the controller returns to the in-wave vessel speed control mode.

8 . The marine propulsion system according to claim 5 , wherein

the remote control lever includes a cancel button to receive the operation to cancel the in-wave vessel speed control mode; and

the controller is configured or programmed to temporarily cancel the in-wave vessel speed control mode for the predetermined period of time when the cancel button of the remote control lever is operated to cancel the in-wave vessel speed control mode.

9 . The marine propulsion system according to claim 1 , wherein

start the in-wave vessel speed control mode when the mode start button is operated to start the in-wave vessel speed control mode; and

temporarily cancel the in-wave vessel speed control mode for the predetermined period of time when the operator is operated, other than operating the mode start button, to cancel the in-wave vessel speed control mode.

15 . The marine propulsion system according to claim 1 , wherein the controller is configured or programmed to perform a notification control to notify the vessel user that the in-wave vessel speed control mode has been temporarily canceled when the in-wave vessel speed control mode has been temporarily canceled.

16 . A marine vessel comprising:

a propulsion device on a hull;

a controller configured or programmed to control driving of the propulsion device to adjust a vessel speed and perform an in-wave vessel speed control to adjust the vessel speed based on information regarding upward-downward movement of the hull; and
