Acceleration control system for marine vessel
First Claim
1. An acceleration control system for a marine vessel, the acceleration control system comprising:
- an actual propulsion power detector that detects an actual value of propulsion power including a rotational speed of a propulsion device of the marine vessel or a speed of the marine vessel;
a setting controller that sets a final target propulsion power of the marine vessel; and
a controller configured or programmed to calculate a target propulsion power of the marine vessel and to control the propulsion device based on the target propulsion power;
whereinthe controller is configured or programmed to set the target propulsion power of the marine vessel at an initial time to an initial target propulsion power, to change the target propulsion power of the marine vessel based on an actual propulsion power of the marine vessel and the initial target propulsion power, and to control the propulsion device such that the actual propulsion power of the marine vessel gets closer to the final target propulsion power; and
the controller is configured or programmed to set the initial target propulsion power to about ⅓
or more of the final target propulsion power.

Abstract
An acceleration control system for a marine vessel includes an actual propulsion power detector, a setting controller configured or programmed to set final target propulsion power of the marine vessel, and a controller. The controller is configured or programmed to set target propulsion power of the marine vessel at an initial time to an initial target propulsion power, to change the target propulsion power of the marine vessel based on an actual propulsion power of the marine vessel and the initial target propulsion power, and to control a propulsion device such that the actual propulsion power of the marine vessel gets closer to the final target propulsion power.
