Abstract:
1. An electronic authentication system for a motorcycle comprising: a portable transmitter-receiver carried by a user; a control unit installed on a motorcycle body; and an ignition switch unit provided with an ignition knob and an access switch, the ignition switch unit electrically connected with the control unit, wherein an axial pressing operation of the ignition knob activates the access switch to begin an electronic authentication, the electronic authentication comprising matching both identification information stored in the portable transmitter-receiver and the control unit respectively; wherein the control unit permits the ignition knob to be rotated from a handle locking position and enables an accommodation box lid to be opened in consequence of the electronic authentication, wherein the ignition switch unit causes a handle to be unlocked in consequence of rotating the ignition knob in a first rotating direction from the handle locking position to a handle unlocking position with an axial pressing operation thereof following the electronic authentication, wherein the ignition switch unit causes a seat to be unlocked in consequence of further rotating the ignition knob in the first rotating direction from the handle unlocking position to a seat unlocking position with the axial pressing operation thereof following the handle unlocking operation, wherein the control unit causes the motorcycle to be an engine startup standby state in consequence of further rotating the ignition knob in the first rotating direction from the handle unlocking position to an engine startup standby position without the axial pressing operation thereof from the handle unlocking position to the engine startup position, wherein the ignition switch unit is provided with an automatic recovery mechanism steadily energizing the ignition knob to rotate in a second rotating direction opposite to the first rotating direction from the seat unlocking position toward the handle unlocking position, and wherein a range of rotating the ignition knob with the axial pressing operation to the seat unlocking position is differed from a range of rotating the ignition knob without the axial pressing operation to the engine startup standby position.
