Abstract

Methods and systems are provided for determining a value of an event performance variable associated with a driving event, and/or for determining a session performance variable associated with at least one driving session. The method comprising: identifying a driving event which occurred during a driving session of a vehicle; providing a plurality of indicators associated with such a driving event; retrieving respective values for each of the plurality of indicators from one or more sensors located in the vehicle being driven; providing a mathematical relationship that represents the event performance variable as a function of the plurality of indicators, wherein the mathematical relationship represents an event of the type characterizing the identified driving event; and determining value of the event performance variable based on the mathematical relationship provided, by applying the values retrieved for each of the plurality of indicators.

Claims
