<p><P>PROBLEM TO BE SOLVED: To increase the operability of a motorcycle while suppressing the slipping of a V-belt, and at the same time, to suppress the deterioration of the V-belt, and also, to reduce a shock at the time of resetting from a slip suppression. <P>SOLUTION: This motorcycle having a non-stage transmission takes in a PPS value from a pulley width of a driving pulley 101 which is detected by a pulley position sensor 130, and sets a PPS ratio value by calculating a transmission ratio under a proper transmission state in response to the PPS value. Then, the rotation number of the driving pulley 101 and the rotation number of a following pulley 103 are taken in from rotation sensors 141 and 142, and a rotation ratio valve (actual transmission ratio) of a CVT device 64 is calculated based on those rotation numbers. Then, whether a difference between the PPS ratio value and the rotation ratio value is a specified value or higher, or not is judged. When the difference is the specified value or higher, it is judged that the V-belt is slipping, and the driving pulley 101 is driven to the closing side by a CVT motor 129. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
