System and method for trimming a trimmable marine device with respect to a marine vessel
First Claim
1. A method for controlling a trim system on a marine vessel, the method comprising:
- receiving an actual trim position of a trimmable marine device at a controller;
determining a trim position error by comparing the actual trim position to a target trim position with the controller;
determining an acceleration rate of the marine vessel, wherein the acceleration rate has a magnitude;
in response to determining that the trim position error exceeds a first error threshold and the magnitude of the acceleration rate exceeds a given rate threshold, commanding the marine device to the target trim position with the controller;
in response to determining that the trim position error exceeds the first error threshold and the magnitude of the acceleration rate does not exceed the given rate threshold, commanding the marine device to a setpoint trim position that is different from the target trim position with the controller; and
trimming the marine device with a trim actuator in response to the controller commanding the marine device to one of the target trim position and the setpoint trim position.

Abstract
A method for controlling a trim system on a marine vessel includes receiving an actual trim position of a trimmable marine device at a controller and determining a trim position error by comparing the actual trim position to a target trim position with the controller. The method also includes determining an acceleration rate of the marine vessel. In response to determining that the trim position error exceeds a first error threshold and the magnitude of the acceleration rate exceeds a given rate threshold, the controller commands the marine device to the target trim position. In response to determining that the trim position error exceeds the first error threshold and the acceleration rate does not exceed the given rate threshold, the controller commands the marine device to a setpoint trim position that is different from the target trim position. An associated system is also disclosed.

11. A system for controlling a trim position of a trimmable marine device with respect to a marine vessel to which the trimmable marine device is coupled, the system comprising:
-
a controller that determines a target trim position of the marine device based on a condition of the marine vessel; a trim position sensor that senses an actual trim position of the marine device and sends actual trim position information to the controller; and a trim actuator coupled to the marine device and configured to rotate the marine device about a horizontal trim axis in response to commands from the controller; wherein the controller determines at least a magnitude of an acceleration rate of the marine vessel; wherein, in response to determining that the magnitude of the acceleration rate exceeds a given rate threshold, the controller commands the trim actuator to rotate the marine device until the trim position sensor indicates that the actual trim position equals the target trim position; and wherein, in response to determining that the magnitude of the acceleration rate does not exceed the given rate threshold, the controller commands the trim actuator to rotate the marine device until the trim position sensor indicates that the actual trim position equals a setpoint trim position that is different from the target trim position. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
