摘要： A method for controlling a hybrid electric driveline 2, comprising an internal combustion engine 3 and an electric machine 5 configured in parallel for driving a propulsion member 9, comprising the steps of: driving the driveline in generator mode, where the electric machine provides a charge current to a battery 11 and where the internal combustion engine provides positive driving torque to the propulsion member, and limiting the maximal available torque from the internal combustion engine to a predetermined torque limitation value depending on the rotational speed of the internal combustion engine.

摘要： A boat includes a dash positioned proximate a windshield at a first non-zero angle. A speaker is mounted under a top surface of the dash at a second non-zero angle. The speaker is positioned to direct sound emanating from the speaker through an opening in the dash and the windshield is configured to reflect the sound emanating from the speaker as reflected sound in an aft direction. The boat may also include an enclosure having a reflective surface positioned within a cavity formed between the deck and hull of the boat. A speaker, mounted within the enclosure, and the reflective surface are configured to reflect sound emanating from the speaker off of the reflective surface and through an opening of the enclosure.

摘要： 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.

摘要： A small boat includes an output that outputs to an engine controller an output signal having an output value at which a throttle opening degree increases as an operation amount of a throttle operator increases, and outputs to the engine controller the output signal having, as an upper limit, a limit output value at which the throttle opening degree is smaller than that at a maximum output value at which the throttle opening degree is maximum.

摘要： A propulsion control system for a marine vessel includes a plurality of propulsion devices steerable to propel the marine vessel, at least one proximity sensor that determines a relative position of the marine vessel with respect to an object, wherein the at least one proximity sensor has a field of view (FOV). A controller is configured to identify a trigger condition for expanding the FOV of the at least one proximity sensor and control thrust and/or steering position of at least one of the plurality of propulsion devices to expand the FOV of the at least one proximity sensor by inducing a roll movement or a pitch movement of the marine vessel.

摘要： A boat includes an engine, an input that receives an input operation performed by an operator, and a controller connected to the input. The controller is powered off when the input does not receive the input operation within a first length of time after the engine is stopped. The controller is not powered off when the input receives the input operation within the first length of time after the engine is stopped.

摘要： A throttle pedal assembly may include: a base; a pedal movably mounted on the base; and an adjustment member extending at least between a first reference location of the throttle pedal assembly and an adjustment surface at an end of the adjustment member. The adjustment member may be adjustable to adjust an adjustment distance from the first reference location of the throttle pedal assembly to the adjustment surface. The throttle pedal assembly may be operable to indicate a throttle level according to relative positions of a second reference location of the throttle pedal assembly and a third reference location of the throttle pedal assembly. Adjusting the adjustment distance may cause an idle position of the pedal to move relative to base and maintains relative positions of the second and third reference locations when the pedal is in the idle position.

摘要： A marine power supply system includes a battery unit including a first battery to supply power to a starter that starts an engine, and a second battery to supply power to an electric motor, and a power distributor connected to the first battery and the second battery. The power distributor outputs a demand power amount of power required by the first battery to the first battery, and outputs at least a portion of surplus power to the second battery when a total demand power amount required by the battery unit includes the surplus power.

摘要： A user input assembly for controlling operation of a trolling motor assembly including a propulsion motor is provided herein. The user input assembly includes a support plate and a foot pedal defining a top surface that is configured to receive a user's foot thereon. The foot pedal is pivotably mounted to the support plate. A deflection sensor is in communication with the foot pedal and is configured to detect an angle of orientation of the foot pedal and output a signal corresponding with the angle of orientation of the foot pedal. The signal is receivable by a controller that is configured to control a direction of the propulsion motor of the trolling motor assembly. A feedback device is coupled with the foot pedal and configured to, in response to pivotal movement of the foot pedal about the first axis, provide a resistance force to the pivotal movement.
