Title:
SYSTEM AND METHOD FOR CONTROLLING TRACTION IN TWO-WHEELED VEHICLE
Document Type and Number:
Japanese Patent JP2010285987
Kind Code:
A
Abstract:

To provide a method for controlling traction in a two-wheeled vehicle, ensuring a good level of stability of the vehicle whilst obtaining the best performances possible to be achieved dependent upon a particular driving condition.

The method for controlling traction in the two-wheeled vehicle includes: a steps of determining a reference slip value (λ0) as a function of a parameter (θ) representative of a torque request from a user, the parameter representative of the torque request being detected by means of a plurality of sensors (122); a step of estimating an instantaneous slip value (λs); and a step of determining a first component (τCL) of a requested torque signal to a motor (121) based upon a difference between the reference slip value and the instantaneous slip value, wherein the reference slip value is determined by means of a torque-slip map correlating the parameter representative of the torque request with a slip (λ), and the torque-slip map varies as a function of a longitudinal speed (v) and a rolling angle () of the two-wheeled vehicle (120) detected by means of the plurality of sensors.
