1. A motor-vehicle driving style estimating system comprising:
- a measuring apparatus of a kinematic signal representative of a motor-vehicle motion quantity trend (v(t)) along a measurement path;
a low-pass filtering module configured to filter the kinematic signal and provide a corresponding reference filtered signal associated with a reference trend of said quantity (vF(t));
a processing module comprising a computing module configured to;
compute from the kinematic signal and a motor-vehicle description model an estimation of an energy used by the motor-vehicle (E1) along the measurement path, andcompute from the reference signal and said motor-vehicle description model a reference energy (E2) associated with the reference trend; and
a first estimating module configured to compare said energy to the reference energy and provide an indication (IND1) about the driving style depending on an offset between the energy and the reference energy.

Abstract
A motor-vehicle driving style estimating system (100) of a motor-vehicle, comprising a measuring apparatus (1) of a kinematic signal representative of a motor-vehicle motion quantity trend (v(t)). The system is characterized in that it further comprises a kinematic signal low-pass filtering module (8) configured to provide a corresponding reference filtered signal associated with a reference trend of said quantity (vF(t)). Furthermore, the system comprises a kinematic signal and reference filtered signal processing module (2) configured to provide an indication of the driving style depending on a comparison of the motor-vehicle motion trend with the reference trend.
