MOTORCYCLE
Document Type and Number:
WIPO Patent Application WO/2011/070941
Kind Code:
A1
Abstract:
Provided is a motorcycle wherein a target slip value is set in accordance with the passenger's operation of an accelerator and wherein the output torque of a drive source can be prevented from rapidly decreasing, and a comfortable feeling during operation can be obtained during traction control. The motorcycle has a target slip value calculation unit which calculates a target slip value on the basis of the passenger's operation of the accelerator, and an actual slip value calculation unit which calculates the actual slip value on the basis of the difference between the rotation speed of a front wheel and the rotation speed of a rear wheel. Further, the motorcycle has a drive source control unit which reduces the output torque of the drive source on the basis of the difference between a reference value different from the target slip value and the actual slip value when the actual slip value is lower than the target slip value.
