发明名称 Watercraft
摘要 In a watercraft, an engine rotational speed sensor detects a rotational speed of an engine. A determining section determines if a prescribed execution condition indicating that a hull body is moving is satisfied. A filter processing section applies a filter process to the engine rotational speed detected by the engine speed sensor to acquire a filtered engine rotational speed. A control section executes a maximum speed limiting control to limit a maximum speed of the watercraft when the prescribed execution condition is satisfied and the filtered engine rotational speed is larger than a prescribed rotational speed threshold value.

主权项 1. A watercraft comprising: a hull body; a propulsion device arranged to propel the hull body; an engine arranged to drive the propulsion device; an engine rotational speed sensor arranged to detect an engine rotational speed; a determining section programmed to determine if a prescribed execution condition indicating that the hull body is moving is satisfied; a filter processing section programmed to apply a moving average filter processing to the engine rotational speed detected by the engine rotational speed sensor to acquire a filtered engine rotational speed; and a control section programmed to execute a maximum speed limiting control to limit a maximum speed of the watercraft when the determining section determines that the hull body is moving and the filtered engine rotational speed is larger than a prescribed rotational speed threshold value; wherein the control section is further programmed to not execute the maximum speed limiting control when the prescribed execution condition is not satisfied even when the filtered engine rotational speed is larger than the prescribed rotational speed threshold value.
