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.

Abstract: A method for controlling a power steering system utilizes a vehicle having a motor, a controller coupled to the motor, and a steering assembly. The method includes detecting a steering rate using the controller. A base level steering damping is computed using the steering rate. At least one approximate vehicle acceleration is determined. A steering torque of the steering assembly is sensed through a torque sensor configured to sense the steering torque of the steering assembly. Moreover, a user torque is determined using the torque sensor. A damping boost is computed using the user torque and the at least one approximate vehicle acceleration. A final steering damping gain is determined using the base level steering damping and the damping boost. The final steering damping gain is applied to the steering assembly to minimize unwanted feedback to the steering assembly.

Abstract: Systems, methods, and devices for enhancing steering control of a recreational vehicle. One or more mechanical dampers are coupled to and resist movement of a steering system of the recreational vehicle, and an electrically actuated device is coupled to the steering system for applying torque to the steering system. A sensor is also positioned adjacent the steering system that generates data indicating an operational state of the recreational vehicle. A first torque applied to the steering system by the one or more mechanical dampers is estimated based on the operational state, a second torque to apply to the steering system by the electrically actuated device is calculated based on the estimated first torque and the operational state, and the electrically actuated device is operated to apply the second torque to the steering system.
