  • Patent number: 8498784
    Abstract: The present invention refers to a method for estimating the suspension stroke of a vehicle comprising the steps consisting of: a) determining a variability law (10) that associates the stroke of the suspension with the pressure inside a shock absorber of the same, based on experimental data; b) estimating the suspension stroke value related to a measured pressure value, based on the variability law (10) identified in step (a); c) detecting/obtaining the longitudinal vehicle dynamics; d) recalibrating (30) the variability law (10) identified in step a), based on the longitudinal vehicle dynamics detected/obtained in step c). The present invention also refers to an apparatus for implementing the estimation method of the suspension stroke of a vehicle according to the invention.

  • Publication number: 20100312449
    Abstract: The present invention refers to a system and method for controlling traction in a two-wheeled vehicle comprising a torque controlled motor and a plurality of sensors for instantaneously measuring driving parameters (v, ?, ?, ?, x, a, RPM, gear) of said vehicle, 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; estimating an instantaneous slip value (?s); determining a first component (tCL) of a requested torque signal to the motor 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 (f) of the two-wheeled vehicle detected by means of the plurality of se

  • Publication number: 20100299028
    Abstract: The present invention refers to a method for controlling an electronically adjustable steering damper in a two-wheeled vehicle or motor vehicle, and to an apparatus implementing it, in which the steering damper is able to exert a damping torque on a steering assembly (45) of the two-wheeled vehicle (40) that can be adjusted according to a steering speed (s{dot over (?)}). The control method comprises the steps that consist of determining at least one controlled variable (s{dot over (?)}, s{dot over (?)}) of the two-wheeled vehicle (40) and calculating an instantaneous damping coefficient (cin(t)) of the electronically adjustable steering damper based on the at least one controlled variable (s{dot over (?)}, s{dot over (?)}) and is characterized in that the at least one controlled variable comprises a yaw rate (s{dot over (?)}) of the two-wheeled vehicle.
