Abstract

A usage management system includes a use rights management server and a user terminal. A controller of a vessel propulsion apparatus operates a prime mover in a permission mode to permit an output exceeding a predetermined limit output if use permission is provided from the user terminal, and operates the prime mover in a non-permission mode to prohibit an output exceeding the predetermined limit output if use permission is not provided from the user terminal. The user terminal enters an active state to allow issuance of use permission if a use-permission notification is received from the use rights management server, and enters a non-active state to prohibit issuance of use permission if a use-permission notification is not received from the use rights management server. The use rights management server transmits a use-permission notification or a use-non-permission notification in accordance with use rights information concerning the vessel propulsion apparatus.

First claim

What is claimed is:

1. A usage management system for a vessel propulsion apparatus including a thrust generator, a prime mover and a controller, the usage management system comprising:
a use rights management server to manage use rights information of a vessel propulsion apparatus that provides a thrust to a vessel; and
a user terminal to exchange data communication with the vessel propulsion apparatus and with the use rights management server; wherein
the controller is configured or programmed to communicate with the user terminal, to operate the prime mover in a permission mode to permit an output exceeding a predetermined limit output if use permission is provided from the user terminal, and to operate the prime mover in a non-permission mode to prohibit the output exceeding the predetermined limit output if use permission is not provided from the user terminal;
the user terminal is operable to transmit a use-permission request with identifications of the vessel propulsion apparatus and a user to the use rights management server, to enter an active state to allow issuance of use permission to the controller if a use-permission notification is received from the use rights management server, and to enter a non-active state to prohibit issuance of use permission to the controller if a use-permission notification is not received from the use rights management server; and
the use rights management server is operable to refer to use rights information concerning the vessel propulsion apparatus when a use-permission request with identifications of the vessel propulsion apparatus and the user is received from the user terminal, and to transmit a use-permission notification or a use-non-permission notification to the user terminal in accordance with the use rights information.

2. The usage management system according to claim 1 , wherein
the prime mover includes an internal combustion engine, a flywheel magneto to rotate in response to rotation of a crankshaft of the internal combustion engine, a charge coil to generate electricity by the rotation of the flywheel magneto, an ignition coil to operate by electric power generated by the charge coil, a pulsar coil to generate an ignition timing signal in accordance with the rotation of the flywheel magneto, and an ignition plug to cause a spark discharge by the power supply from the ignition coil;
the controller is provided in a capacitor discharge injection (CDI) ignition that passes an electric current through the ignition coil in accordance with the ignition timing signal generated by the pulsar coil and generates the spark discharge in the ignition plug; and
the controller is configured or programmed to execute an operation of the prime mover in the permission mode and in the non-permission mode by controlling the spark discharge from the ignition plug.

3. The usage management system according to claim 2 , wherein
the CDI ignition includes an ignition disabling circuit to disable an operation that passes the electric current through the ignition coil in accordance with the ignition timing signal generated by the pulsar coil when a rotation speed of the prime mover reaches a rotation speed limit; and
the controller is configured or programmed to set a first rotation speed at the rotation speed limit in the permission mode and to set a second rotation speed lower than the first rotation speed in the non-permission mode.

4. The usage management system according to claim 2 , wherein the controller is configured or programmed to pass the electric current through the ignition coil at a timing subjected to a phase shift with respect to the ignition timing signal generated by the pulsar coil in the permission mode and to disable the phase shift in the non-permission mode.

5. The usage management system according to claim 2 , wherein
the CDI ignition is detachably fixed to an engine block of the prime mover;
an identification information tag to identify the vessel propulsion apparatus is fixed to the engine block;
the CDI ignition includes a readout unit connected to the controller and operable to read out identification information from the identification information tag; and
the controller is configured or programmed to operate the prime mover in the non-permission mode when the readout unit does not read out the identification information.

6. The usage management system according to claim 1 , wherein
the use rights management server is operable to issue a use-permission notification accompanied by a validity-period information based on the use rights information; and
the user terminal is operable to determine whether a current time is within a validity period indicated by the validity-period information when the use-permission notification is accompanied by the validity-period information, and to enter the active state if the current time is within the validity period, and to enter the non-active state if the current time is outside the validity period.

7. The usage management system according to claim 6 , wherein
the user terminal includes a storage to non-volatilely store the use-permission notification; and
the user terminal is operable to determine whether the current time is within a validity period indicated by the validity-period information when the use-permission notification stored in the storage is accompanied by the validity-period information, to enter the active state if the current time is within the validity period, and to enter the non-active state if the current time is outside the validity period.

8. The usage management system according to claim 1 , wherein
the use rights management server is operable to issue a use-permission notification accompanied by validity-period information based on the use rights information;
the user terminal is operable to provide the validity-period information and use-permission to the controller when the use-permission notification is accompanied by the validity-period information; and
when the use-permission and the validity-period information are provided from the user terminal, the controller is configured or programmed to determine whether the current time is within the validity period indicated by the validity-period information when the operation of the prime mover is started, to operate the prime mover in the permission mode if the current time is within the validity period, and to operate the prime mover in the non-permission mode if the current time is outside the validity period.

9. The usage management system according to claim 8 , wherein
the controller includes a storage to non-volatilely store the use-permission and the validity-period information; and
the controller is configured or programmed to, when the use-permission and the validity-period information are stored in the storage, to operate the prime mover in the permission mode without obtaining the use-permission from the user terminal within the validity period indicated by the validity-period information, and to operate the prime mover in the non-permission mode outside the validity period indicated by the validity-period information if the use-permission is not provided from the user terminal.

10. The usage management system according to claim 1 , wherein the use rights information to which the use rights management server refers includes at least one among information concerning a loan payment situation of purchase money of the vessel propulsion apparatus, information concerning a payment situation of rental charges of the vessel propulsion apparatus, or information concerning a use period restriction of the vessel propulsion apparatus.

11. The usage management system according to claim 1 , wherein the controller
