Abstract

A saddle-riding vehicle includes a front wheel suspension device which supports a steering wheel (front wheel) and a steering handle (bar handle 4 ), a chassis frame which supports the front wheel suspension device to be steerable, a handle lock mechanism 60 which locks the steering of the front wheel suspension device with respect to the chassis frame at a predetermined handle lock position P 1 , a steering actuator 43 which applies an assist torque to the front wheel suspension device, and a control device 23 which controls the driving of the steering actuator 43 . The control device 23 operates the steering actuator 43 so that the front wheel suspension device is turned to the handle lock position P 1 when detecting a predetermined lock standby state.

First claim

What is claimed is:

1. A saddle-riding vehicle comprising:
a suspension device ( 3 ) which supports a steering wheel ( 2 ) and a steering handle ( 4 );
a chassis frame ( 5 ) which supports the suspension device ( 3 ) to be steerable;
a handle lock mechanism ( 60 ) which locks the steering of the suspension device ( 3 ) with respect to the chassis frame ( 5 ) at a predetermined handle lock position (P 1 );
a steering actuator ( 43 ) which applies an assist torque (Tm) to the suspension device ( 3 ); and
a controller ( 23 ) for controlling the driving of the steering actuator ( 43 ),
wherein the controller ( 23 ) performs handle lock control of operating the steering actuator ( 43 ) so that the suspension device ( 3 ) is turned to the handle lock position (P 1 ) when detecting a predetermined lock standby state.

2. The saddle-riding vehicle according to claim 1 , further comprising:
stands ( 18 , 19 ) which support the chassis in an upright state,
wherein the lock standby state is a state in which a predetermined handle lock request operation is performed while the chassis is supported by the stands ( 18 , 19 ).

3. The saddle-riding vehicle according to claim 2 ,
wherein the handle lock request operation is a predetermined lock operation for at least one of a switch ( 30 ) provided on the vehicle and a wireless device ( 64 ) separated from the vehicle.

4. The saddle-riding vehicle according to claim 2 ,
wherein the stands ( 18 , 19 ) includes a side stand ( 18 ) which supports the chassis in an upright state inclined toward one of the left and right sides, and
wherein the suspension device ( 3 ) is turned to the side stand ( 18 ) to reach the handle lock position (P 1 ).

5. The saddle-riding vehicle according to claim 1 ,
wherein the handle lock mechanism ( 60 ) includes a handle lock actuator ( 61 ), and
the controller ( 23 ) performs the handle lock control of operating the handle lock actuator ( 61 ) to a lock state of automatically locking the steering of the suspension device ( 3 ) after the suspension device ( 3 ) is turned to the handle lock position (P 1 ).

6. The saddle-riding vehicle according to claim 5 ,
wherein the controller ( 23 ) cancels the handle lock control when the suspension device ( 3 ) is not fully turned to the handle lock position (P 1 ) within a specified time (t 1 ) or the handle lock actuator ( 61 ) is not fully operated to the lock state within a specified time (t 2 ).
