ABSTRACT:
An antifraud device for a vehicle has a tank with a filler provided with a removable cap. The device comprises a first sensor, for detecting a movement of the cap with respect to the filler, and second sensor, configured for detecting at least one of the level and a qualitative characteristic of the contents of the tank. A control unit generates first information being indicative of detections made by the first sensor, and second information being indicative of detections made by the second sensor, and stores the information in a correlated form. The device is further arranged for making explicit the first information and the second information in a correlated form, in order to identify one or more of the following conditions: removal of at least part of the contents of the tank; dilution or alteration of the contents of the tank; replacement of at least part of the contents of the tank; effective removal of the cap following upon a movement thereof in the filler.
