Title:
FUEL THEFT DETECTION METHOD AND FUEL THEFT DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/157593
Kind Code:
A1
Abstract:
A fuel MS unit (2) acquires, from a fleet MS unit (2), a remainder that is detected by a remainder sensor by sampling at a prescribed interval and sequentially calculates the average value of the most recently sampled remainder and the remainders sampled a prescribed number of times previously. The fuel MS unit (3) calculates a smoothed average value by sequentially correcting the most recently calculated average value to reduce the difference between the most recently calculated average value and the previously calculated average value and detects fuel theft on the basis of the smoothed average value. When it has been determined that refueling has occurred or that fuel has been stolen while an ignition was off, the fuel MS unit (3) uses the uncorrected most recently calculated average value as the smoothed average value.
