Abstract: The invention relates to a system comprising a plurality of first sensors to measure parameters characterizing a vehicle operating state; a second sensor to measure a parameter characterizing an emission of an fuel processing apparatus; a control device to measure repeatedly over a predefined time period and to determine a vehicle operating state based on a first data set with measured values from the plurality of first sensors and predefined parameter ranges describing a predefined vehicle operating state; an allocation device to allocate a second data set comprising measured values from the second sensor to the predefined vehicle operating state; and an evaluation device to determine a characteristic value for assessing or optimizing the operating behavior of the vehicle based on the vehicle operating state and the second data set, wherein the characteristic value characterizes an energy efficiency of the vehicle or an emission behavior of the fuel processing apparatus.

Abstract: The invention relates to a system for assessing and/or optimising the operating behaviour of a vehicle that has at least one apparatus for processing fuel, in particular an internal combustion engine and/or a fuel cell, wherein the system has: a plurality of first sensors designed to measure parameters that are suitable for characterising a vehicle operating state; at least one second sensor designed to measure at least one parameter that is suitable for characterising an emission of the apparatus for processing fuel; a control device designed to measure repeatedly over a predefined time period and to determine a vehicle operating state on the basis of a first data set with measured values from the plurality of first sensors and on the basis of predefined parameter ranges that describe at least one predefined vehicle operating state; an allocation device designed to allocate a second data set comprising measured values from the at least one second sensor to the at least one predefined vehicle operating state;
