  • Patent number: 10797907
    Abstract: A controller associated with a propulsion device in a marine propulsion system is configured to send and receive controller area network (CAN) messages on a CAN bus and has computer-executable instructions stored thereon executed by a processor of the controller to perform a method. The method includes receiving a configuration instruction CAN message containing a new configuration value, determining that the configuration instruction CAN message is directed to itself, and then receiving a reboot CAN message. Upon determining that the reboot CAN messages directed to itself, the controller writes the new configuration value to memory and then controls a power relay to power off the controller, ignoring a key switch value associated with the propulsion device being on. The controller then responds to the key switch value to power the controller back on, and then loads the new configuration value into the working memory of the controller.

  • Patent number: 10351221
    Abstract: A method for controlling a trim position of a marine propulsion device includes receiving operator demands corresponding to propulsion system operating speeds and determining a rate of change of demand versus time between an initial and a subsequent operator demand. When the rate of change of demand exceeds a predetermined rate, the control module uses successively measured operating speeds of the propulsion system and an offset trim profile to determine setpoint trim positions for the propulsion device. As the propulsion system's measured operating speed increases from an initial to a subsequent operating speed, the control module controls a trim actuator to rotate the propulsion device to the setpoint trim positions. An operating speed at which the propulsion device begins trimming up is less according to the offset trim profile than according to a base trim profile, which is utilized when the rate of change does not exceed the predetermined rate.

  • Patent number: 10137971
    Abstract: A trim control system automatically controls trim angle of a marine propulsion device with respect to a vessel. A memory stores trim base profiles, each defining a unique relationship between vessel speed and trim angle. An input device allows selection of a base profile to specify an aggressiveness of trim angle versus vessel speed, and then optionally to further refine the aggressiveness. A controller then determines a setpoint trim angle based on a measured vessel speed. If the user has not chosen to refine the aggressiveness, the controller determines the setpoint trim angle from the selected base profile. However, if the user has chosen to refine the aggressiveness, the controller determines the setpoint trim angle from a trim sub-profile, which defines a variant of the relationship between vessel speed and trim angle defined by the selected base profile. The control system positions the propulsion device at the setpoint trim angle.

  • Patent number: 10095232
    Abstract: A method for maintaining position and/or heading of a marine vessel in a body of water includes accepting a command to maintain the vessel at an initial selected position and/or heading, and utilizing position/heading feedback control to determine initial steering angles, gear positions, and engine speeds for the vessel's propulsion devices that cause the propulsion devices to produce thrust that counteracts a net external force and moment on the vessel and maintains the vessel at the initial selected position/heading. The method also includes propelling the vessel to a new selected position/heading, and accepting a command to maintain the vessel at the new selected position/heading. The method next includes utilizing information related to one of the position/heading feedback control and the propulsion devices' thrust to predict control parameters required to maintain the vessel at the new selected position/heading, and controlling the propulsion device according to the predicted control parameters.

  • Patent number: 10059417
    Abstract: A marine propulsion device includes an internal combustion engine driving a driveshaft into rotation and a starter-generator motor in a torque transmitting relationship with the driveshaft. The starter-generator motor is alternately operable in a positive torque mode where it is powered by a battery to exert a positive torque on the driveshaft, and in a negative torque mode where it exerts a negative torque on the driveshaft and generates a charge to the battery. A control module is configured to receive an engine RPM, determine an engine RPM drop rate, and determine that the engine RPM drop rate exceeds a threshold drop rate. The starter-generator motor is then operated in a positive torque mode based on the engine RPM drop rate when the engine RPM drop rate exceeds the threshold drop rate.

  • Patent number: 9991785
    Abstract: The objective of the present invention is to provide an electric power converting device with which can executes a ground fault detection in a short time with its inexpensive configuration. In one step, the electric power converting device performs level comparison of a difference between output values of low pass filters, with a threshold value ?E. If a W-phase is shorted to ground at a time when the U-phase and V-phase lower arm IGBTs are ON and W-phase upper IGBT is ON, the difference between the output values of the low pass filters and becomes small. In another step, a level comparison is made between the absolute value of a difference between the U-phase current value iu and U-phase current command value iu?, and a threshold value F. If the absolute value is lower than the threshold value, the result is determined to be normal, and if the absolute value is greater than the threshold value, the result is determined to be abnormal, because the U-phase is shorted to ground.
