Personal watercraft

Abstract

A personal watercraft includes: a watercraft body including a boarding section on which a driver boards and a sub-boarding section on which a mounted object other than the driver is mounted; a mounted object overboard detection unit that detects that the mounted object has fallen overboard from the watercraft body; and a notification unit that performs notification control to notify the driver of the falling overboard through a specific control target when the mounted object overboard detection unit detects that the mounted object has fallen overboard.

1 . A personal watercraft comprising:
 a watercraft body including a boarding section on which a driver boards and a sub-boarding section on which a mounted object other than the driver is mounted;   a mounted object overboard detection unit that detects that the mounted object has fallen overboard from the watercraft body; and   a notification unit that performs notification control to notify the driver of the falling overboard through a specific control target when the mounted object overboard detection unit detects that the mounted object has fallen overboard.   
     
     
         2 . The personal watercraft according to  claim 1 , further comprising a drive source that generates a driving force for moving the watercraft body,
 wherein the notification unit controls, as the notification control, the drive source in a special mode different from a mode before detection of falling overboard of the mounted object.   
     
     
         3 . The personal watercraft according to  claim 2 , wherein in the special mode, output of the drive source is restricted as compared with output before detection of falling overboard of the mounted object. 
     
     
         4 . The personal watercraft according to  claim 1 , wherein the mounted object overboard detection unit includes a communication terminal attached to the mounted object, and a determination unit that determines whether or not the mounted object has fallen overboard based on a communication state with the communication terminal. 
     
     
         5 . The personal watercraft according to  claim 4 , wherein the determination unit determines, based on a communication state with the communication terminal, each of whether or not a first condition has been satisfied, the first condition being that the mounted object has been mounted on the watercraft body during a planing preparation period, and whether or not a second condition has been satisfied, the second condition being that the mounted object has been separated from the watercraft body exceeding a predetermined distance during planing, and when both of the first condition and the second condition are confirmed to be satisfied, determines that the mounted object has fallen overboard. 
     
     
         6 . The personal watercraft according to  claim 1 , wherein
 the mounted object is a passenger, and   the sub-boarding section is a passenger seat on which the passenger can be seated.   
     
     
         7 . The personal watercraft according to  claim 1 , wherein
 the mounted object is luggage, and   the sub-boarding section is luggage storage provided at a rear of a seat on which the driver is seated.   
     
     
         8 . The personal watercraft according to  claim 1 , further comprising:
 a driver overboard detection unit that detects that the driver has fallen overboard from the watercraft body;   a power unit that moves the watercraft body; and   a control unit that controls the power unit in a mode different from a mode at a time of detection of falling overboard of the mounted object in a case where the driver overboard detection unit detects falling overboard of the driver.   
     
     
         9 . The personal watercraft according to  claim 8 , wherein when falling overboard of the driver is detected, the control unit controls the power unit so that movement of the watercraft body is restricted as compared with movement of the watercraft body before the detection of the falling overboard. 
     
     
         10 . The personal watercraft according to  claim 9 , wherein
 the power unit includes a drive source, a jet pump that is rotationally driven by the drive source and injects water, and a reverse bucket that is swingably arranged at an outlet of the jet pump,   when falling overboard of the driver is detected, the control unit restricts movement of the watercraft body by stopping the drive source or changing a position of the reverse bucket to a neutral position, and   when falling overboard of the mounted object is detected, the notification unit restricts output of the drive source while continuing operation of the drive source as compared with output before detection of falling overboard of the mounted object.   
     
     
         11 . The personal watercraft according to  claim 9 , wherein when falling overboard of the driver is detected, the control unit controls the power unit so that the watercraft body remains in an area where a distance from a point of falling overboard of the driver to the watercraft body is equal to or less than a predetermined value. 
     
     
         12 . A personal watercraft comprising:
 a watercraft body including a boarding section on which a driver boards and a sub-boarding section on which a mounted object other than the driver is mounted;   a determination unit that determines whether or not the mounted object has fallen overboard from the watercraft body based on presence or absence of the mounted object detected during a planing preparation period and presence or absence of the mounted object detected during subsequent planing; and   a notification unit that performs notification control to notify the driver of the falling overboard through a specific control target when the determination unit determines that the mounted object has fallen overboard.
