Nowadays, many researches exist in the automotive field aimed at improving vehicle active control. Recently, the possibility to exploit sensors fixed inside the tyre (particularly on the liner) has been presented by the authors of this paper [F. Braghin, M. Brusarosco, F. Cheli, A. Cigada, S. Manzoni, and F. Mancosu, Measurement of contact forces and patch features by means of accelerometers fixed inside the tyre to improve future car active control, Vehicle Syst. Dyn. 44(1) (2006), pp. 3–13]. These sensors allow measurements to be obtained from the closest point to the contact patch, making possible the best description of contact phenomena (with respect to the actual situation in which sensors are usually placed on the hub); these data can be sent to the vehicle controller, processed and therefore used for active control. However, there is still a tyre layer between the sensors and the road, therefore a specific study of the transfer functions between tyre input and sensor signals is needed to understan... |
