Abstract

Smart sensors and transducers are being widely employed in the development of electronically controlled systems, such as advanced suspensions, to improve the performance guaranteed by terrestrial vehicles. Nevertheless, a standard reference for the full exploitation of the smart features is not yet extensively adopted. The CAN-bus is only used for the communication functionalities within a sensor network, resulting in cost-effective and more reliable connections. An original data-driven approach, based on both the CAN-bus and the IEEE ISO/IEC/IEEE 21451 standard, is proposed for the characterization of suspension systems of two-wheel vehicles with regard to the comfort and vehicle handling. Because of the ISO/IEC/IEEE 21451, the data acquired from sensor are sent by means of a GPS-General Packet Radio Service module to PC software that implements the processing algorithm. The proposed methodology includes a low-cost measurement setup, data processing algorithms in both time and frequency domain, and the introduction of model-free synthetic indices to experimentally compare the on-road behavior influenced by different damping characteristics for the suspension system. The method is applied to the on-road verification of the riding comfort assured by different control strategies for semiactive suspensions.
