A system for measuring the grip between a vehicle wheel tyre and a road surface comprising a fibre optic (19) provided with FBG sensors (21) affixed to the internal surface of the tyre, which record data regarding the state of state of residual grip Grs of the tyre to the road. The fibre optic (19) has an end part (20) which, through an optical joint (5, 6) transmits the data to an instrumentation of the vehicle, making it pass through a spectrum analyser (12), a data processing system (14), which implements the residual grip identification algorithm Grs. The residual grip information is sent to a display that is visible by the driver and/or to active control systems for driving the vehicle.

Abstract
A system for measuring the grip between a vehicle wheel tyre and a road surface comprising a fibre optic (19) provided with FBG sensors (21) affixed to the internal surface of the tyre, which record data regarding the state of state of residual grip Grs of the tyre to the road. The fibre optic (19) has an end part (20) which, through an optical joint (5, 6) transmits the data to an instrumentation of the vehicle, making it pass through a spectrum analyser (12), a data processing system (14), which implements the residual grip identification algorithm Grs. The residual grip information is sent to a display that is visible by the driver and/or to active control systems for driving the vehicle.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
