The vehicle mass and its distribution on the vehicle is an important information for several applications, from safety-oriented control systems to fleet management in public transport, courier services, garbage collection and so on. Specifically, an online estimation of such quantities must be provided and the results should be available relying on a minimum set of sensors, to reduce costs and possibly avoid an ad-hocinstrumentation. This paper proposes a frequency-based data processing scheme to address this issue, which relies on vertical acceleration and speed angular velocity measurements only. The validity of the approach is assessed both on simulations in a multibody environment and on experimental data.
