Anordning och förfarande för detektering av onormalt avlägsnande av bränsle ur en bränsletank

摘要

The invention relates to a method for detecting the abnormal removal of fuel from a fuel tank (230) of a motor vehicle (100; 110), comprising the steps of:
- continuously detecting (s330) changes in the fuel quantity in said tank (230) to determine whether said fuel quantity is being changed normally or otherwise;
- triggering (s330) a signal (S1) if said fuel quantity is being changed abnormally,
- detecting the fuel level (L) in said tank (230) using a non-mechanical level sensor (200) adapted to determine whether said fuel quantity is being changed normally or otherwise; where
- said signal (S1) is transmitted by means of said level sensor (200) to an existing alarm system (270) in the vehicle (100; 110). The invention relates also to a computer programme product comprising programme code (P) for a computer (200; 270; 400) for executing a method according to the invention. The invention also relates to a device for detecting the abnormal removal of fuel from a fuel tank in a motor vehicle (100; 110) and a motor vehicle equipped with the device.
