摘要： The speed of a marine propulsion system's engine is temporarily elevated in response to a decrease in helm demand. A controller receives a command to decrease the helm demand from a first helm demand to a second helm demand and compares a demand difference between the second helm demand and the first helm demand to a threshold demand delta. In response to the demand difference exceeding the threshold demand delta, the controller tabulates a time since the demand difference exceeded the threshold demand delta and determines an engine speed offset based upon the second helm demand and the time. The controller determines a non-elevated engine speed setpoint corresponding to the second helm demand and calculates an elevated engine speed setpoint based on the non-elevated engine speed setpoint and the engine speed offset. Engine speed is then decreased to the elevated engine speed setpoint.

摘要： A method for setting an engine speed of an internal combustion engine in a marine propulsion device of a marine propulsion system to an engine speed setpoint includes determining the engine speed setpoint based on an operator demand and predicting a position of a throttle valve that is needed to achieve the engine speed setpoint. The method also includes determining a feed forward signal that will move the throttle valve to the predicted position, and after moving the throttle valve to the predicted position, adjusting the engine speed with a feedback controller so as to obtain the engine speed setpoint. An operating state of the marine propulsion system is also determined. Depending on the operating state, the method may include determining limits on an authority of the feedback controller to adjust the engine speed and/or determining whether the operator demand should be modified prior to determining the engine speed setpoint.

摘要： A method for setting an engine speed of an internal combustion engine in a marine propulsion system to an operator-selected engine speed includes predicting a position of a throttle valve of the engine that is needed to provide the operator-selected engine speed, and determining a feed forward signal that will move the throttle valve to the predicted position. After moving the throttle valve to the predicted position, the method next includes controlling the engine speed with a feedback controller so as to obtain the operator-selected engine speed. The feed forward signal is determined based on at least one of the following criteria: an operator-selected control mode of the marine propulsion system; and an external operating condition of the marine propulsion system. A system for setting the engine speed to the operator-selected engine speed is also described.

摘要： A system for notifying an operator of a marine vessel that a marine propulsion device is not at an efficient trim angle includes a notification device and a controller that sends a signal to the notification device to provide a trim up notification when the controller determines that the marine propulsion device is not at the optimal trim angle. The controller determines this based on at least one of the following: a current load on an engine of the marine propulsion device; a current fuel flow provided to the engine; a current air flow provided via a throttle valve to the engine; or an output from a PID control section of the controller that controls a position of the throttle valve. A method that compares a measured engine speed to an optimal engine speed corresponding to operation of the marine propulsion device at an optimal trim angle is also provided.

摘要： Systems and methods are for cooling a marine propulsion system on a marine vessel. A lift pump pumps raw cooling water from a body of water in which the marine vessel is situated. The lift pump pumps the raw cooling water through an open cooling circuit from an upstream inlet for receiving the raw cooling water to a downstream outlet for discharging the cooling water back to the body of water. A control circuit controls operation of the lift pump. At least one sensing device indicates whether the lift pump is connected to the body of water. The sensing device is in communication with the control circuit. The control circuit prevents operation of the lift pump when the sensing device indicates that the lift pump is not connected to the body of water.

摘要： Systems and methods are for controlling of a hybrid propulsion system for a marine vessel. A control circuit controls an electric motor-generator according to at least two modes, including a first mode wherein the electric motor-generator receives power from a battery and rotates a driveshaft to drive a propulsor and a second mode wherein the electric motor-generator generates power to charge the battery based upon torque from an internal combustion engine. A time criteria and at least one user-desired operational characteristic of at least one of the internal combustion engine, electric motor-generator, and battery are input to the control circuit. Based on the time criteria and user-desired operational characteristic, the control circuit calculates a schedule for at least one of charging the battery with the electric motor-generator and discharging the battery to a house load of the marine vessel. The control circuit further controls operation of the electric motor-generator according to the schedule.
