Fuente: Wipo "BigData" A method and computer programmes for the management of vehicle fleets are proposed. The method comprises the obtaining of data concerning the state and the operation of each of a plurality of vehicles of a particular type in a vehicle fleet; detecting an anomalous average fuel consumption over a certain period in at least one first vehicle of said vehicle fleet on the basis of analysis of the data received; determining and accounting for the cause of said anomalous average fuel consumption detected by means of the implementation of an explainable artificial intelligence algorithm that takes into account different parameters of the first vehicle, including parameters concerning: the driving behaviour of the first vehicle over a set period of time, the state of the first vehicle and a number of meteorological and environmental elements, and deducing the influence of each of the parameters.
