Abstract
A driving style evaluation system (1) for a motor vehicle (2), configured to receive and process motor vehicle-related data and motor vehicle mission-related data to compute a Driving Style Evaluation Index (DSEI) indicative of the driving style of a motor vehicle driver during a motor vehicle mission in relation to a motor vehicle fuel consumption, based on the following summary index: Fuel Economy Index (FEI), which is indicative of the driving style of the motor vehicle driver from the fuel saving perspective, and is computed based on pre-summary indices computed based on respective partial indices in turn computed based on a combination of the following physical quantities which affect the motor vehicle fuel consumption: time interval, ending with a motor vehicle stop, during which the motor vehicle speed reduction is mainly due to a combination of a gas pedal release and a gear downshift, possibly with operation of at least one motor vehicle braking system only during the final part of the maneuver; engine speed and torque fluctuations within preset time intervals; time elapsed between a gas pedal release and operation of at least one motor vehicle braking system; time during …
