Abstract:
1. A driving style evaluation system for a motor vehicle, comprising: a processor configured to receive and process motor vehicle-related data and motor vehicle mission-related data to compute a Driving Style Evaluation Index indicative of the driving style of a motor vehicle driver during a motor vehicle mission from a motor vehicle fuel consumption perspective, based on the following summary index: Fuel Economy Index, 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 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; at least one of: at least one of: and at least one of: and wherein the pre-summary and partial indices are weighted by respective dynamic weighting coefficients, each of which is computed based on a respective motor vehicle mission-independent weight, which is indicative of the influence that the physical quantities based on which the Fuel Economy Index is computed have on the overall fuel consumption reduction, and based on a respective motor vehicle mission-dependent benefit, which represents an evaluation of the benefit that the Fuel Economy Index provides in the driving style evaluation during the motor vehicle mission.
