Abstract: Personal watercraft, driving control system of a jet powered personal watercraft, and method for enhancing steering control of same. The watercraft includes a jet powered propulsion system; a steering system coupled to the propulsion system and including a handle for adjusting an angle of the propulsion system relative a longitudinal axis of the watercraft; and the driving control system including an electrically actuated device coupled to the steering system for applying torque thereto; and a controller coupled to the electrically actuated device and the sensor, the controller configured to: receive a navigation target; determine a torque to apply to the steering system based on the navigation target; and operate the electrically actuated device to apply the torque to the steering system for providing enhanced steering control, with the torque being applied only by the electrically actuated device.

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.

Abstract: A snowmobile having enhanced steering control has driving control system including an electrically actuated device coupled to a steering system having a user operated steering element with the device applying torque to the steering system, a throttle, a plurality of sensors including a torque sensor and at least one additional sensor to generate terrain condition data and operational data, and at least one controller coupled to the device and the sensors. The at least one controller selects a terrain condition mode using the generated terrain condition and generated operational data, determines the torque to apply responsive to the angle and speed of rotation of user operated steering element, and operates the electrically actuated device to apply the torque to the steering system, with the torque being applied only by the electrically actuated device.
