STRADDLED-VEHICLE AUTHENTICATION SYSTEM AND STRADDLED VEHICLE

摘要

A straddled-vehicle authentication system and a straddled vehicle are provided that achieve a suppression of an increase in power consumption while performing an authentication in the straddled vehicle using a portable device, and that also achieve a suppression of an increase in the size of the straddled vehicle which may otherwise result from an increase in the size of a battery. The straddled-vehicle authentication system is configured such that its state is switchable from an OFF state (Q2), through at least an authentication verifying state (Q3) and an authentication verified state (Q4), to a power-unit ON state (Q5). The authentication verifying state (Q3) is a state entered by a transition from the OFF state (Q2), the transition caused by a displacement of a main operation part, the displacement caused in response to a load applied to the main operation part in the OFF state (Q2). The authentication verifying state (Q3) is a state in which an authentication control unit performs an authentication verifying operation. The authentication verified state (Q4) is a state entered by a transition from the authentication verifying state (Q3), the transition caused by a displacement of the main operation part, the displacement caused in response to a load applied to the main operation part in a state where the authentication performed by the authentication control unit has been verified in the authentication verifying state (Q3). The authentication verified state (Q4) is a state in which a power source of a power unit control unit is off and the authentication performed by the authentication control unit has been verified.
