  • Publication number: 20240002029
    Abstract: A personal watercraft, driving control system, and method for controlling the watercraft. The watercraft includes a jet powered propulsion system; a steering system including a handle; and the driving control system including an electrically actuated device coupled to the steering system for applying torque to the steering system; at least one sensor positioned adjacent the steering system; and a controller. The controller is configured to: determine whether user torque is being applied to the steering system; and responsive to determining that the user torque is not being applied: determine a steering angle; determine a target angle for returning the steering system to a center position; compare the steering angle to the target angle; determine a centering torque; and operate the electrically actuated device to apply the centering torque to the steering, with the centering torque being applied only by the electrically actuated device.

  • Patent number: 11738846
    Abstract: Systems, methods, and devices for enhancing steering control of a personal watercraft. An electrically actuated device is coupled to the steering system of the personal watercraft and applies torque to the steering system. At least one sensor is positioned adjacent the steering system and generates operational data of the personal watercraft. At least one controller is coupled to the electrically actuated device and the at least one sensor, and is configured to determine a first torque to apply to the steering system based on the operational data responsive to a second torque being applied to the steering system. The at least one controller is further configured to operate the electrically actuated device to apply the first torque to the steering system for providing enhanced steering control of the personal watercraft, with the first torque being applied only by the electrically actuated device.
