Abstract
A control system for a watercraft includes a device on or in the watercraft, a sensor, and a computer. The sensor is operable to detect status data indicating a status of the device. The computer is configured or programmed to store a decision logic to determine whether or not a malfunction or trouble of the watercraft has occurred, and determine whether or not the malfunction or trouble has occurred based on the status data with reference to the decision logic.
Claims17
A control system for a watercraft, the control system comprising:
- a device on or in the watercraft;
- a sensor to detect status data indicating a status of the device;
- and
- a computer configured or programmed to:
- store a decision logic to determine whether or not a malfunction or trouble of the watercraft has occurred;
- and
- determine whether or not the malfunction or trouble of the watercraft has occurred based on the status data with reference to the decision logic;
- wherein
- the device includes:
- a drive source;
- a shift mechanism including a clutch to transmit a drive force generated by the drive source;
- and
- a shift actuator to switch between engagement and disengagement of the clutch;
- and
- the computer is configured or programmed to:
- detect a number of times of an operation of the shift actuator to engage the clutch as the status data;
- determine whether the operation of the shift actuator is continuously repeated a predetermined number of times or greater;
- and
- determine that the malfunction or trouble has occurred in the clutch when the number of times of the operation of the shift actuator is continuously repeated to engage the clutch is the predetermined number of times or greater.

A method for controlling a watercraft including a watercraft body and a device installed on or in the watercraft body, the method comprising:
- obtaining status data indicating a status of the device;
- and
- determining whether or not a malfunction or trouble of the watercraft has occurred based on the status data with reference to a decision logic to determine whether or not the malfunction or trouble of the watercraft has occurred;
- wherein
- the device includes a drive source, a shift mechanism including a clutch to transmit a drive force generated by the drive source, and a shift actuator to switch between engagement and disengagement of the clutch, the method further comprising:
- detecting a number of times of an operation of the shift actuator to engage the clutch as the status data;
- determining whether the operation of the shift actuator is continuously repeated a predetermined number of times or greater;
- and
- determining that the malfunction or trouble has occurred in the clutch when the number of times of the operation of the shift actuator is continuously repeated to engage the clutch is the predetermined number of times or greater.
