Patent number: 11584498Abstract: An actuator for imparting steering movement to a tiller of a propulsion unit of a marine vessel comprises an absolute position sensor operable to sense a steering position and a relative position sensor operable to sense a position of the motor. A steering control unit calibrates the relative position sensor based on a signal of the absolute position sensor. Calibration of the relative position sensor based on a signal of the absolute position sensor initializes an accumulative position which accumulates a relative position as the actuator moves over time.Type: GrantFiled: March 8, 2021Date of Patent: February 21, 2023Assignee: Marine Canada Acquisition Inc.Inventors: Anson Chin Pang Chan, Ian Michael Carlson, Ray Tat Lung Wong, Mark Isaac Dyck

Publication number: 20210300517Abstract: A marine vessel control system comprises a propulsion unit and a steering actuator for steering the propulsion unit. There is a shift actuator for shifting gears in the propulsion unit and a throttle actuator for increasing or decreasing throttle to the propulsion unit. There is an input device for providing user inputted steering commands to the steering actuator and for providing user inputted shift and throttle commands to the shift actuator and the throttle actuator. There is a sensor for detecting a global position and a heading direction of the marine vessel. A controller receives position and heading values of the marine vessel from the sensor. The controller compares the received position value to a pre-programmed position value to determine a position error difference. The controller also compares the received heading value to a pre-programmed heading value to determine a heading error difference.Type: ApplicationFiled: June 11, 2021Publication date: September 30, 2021Inventors: Ray Tat Lung WONG, Pierre GARON, Geoffrey David DUDDRIDGE
