System and method for controlling traction in a two-wheeled vehicle

摘要

The present invention refers to a system and method for controlling traction in a two-wheeled vehicle (120) comprising a torque controlled motor (121) and a plurality of sensors (122) for instantaneously measuring driving parameters (v,Õ,¸,É,x,a,RPM,gear) of said vehicle (120), the method comprising the steps of determining a reference slip value (» 0 ) as a function of a parameter (¸) representative of a torque request from a user detected by means of the plurality of sensors (122); estimating an instantaneous slip value (» s ); determining a first component (Ä CL ) of a requested torque signal to the motor (121) based upon the difference between the reference slip value (» 0 ) and the instantaneous slip value (» S ); and is characterised in that the reference slip value (» 0 ) is determined by means of a torque-slip map correlating the parameter (¸) representative of a torque request with a slip (»), the map varying as a function of a longitudinal speed (v) and a rolling angle (Õ) of the two-wheeled vehicle (120) detected by means of the plurality of sensors (122).
