Abstract

Method and arrangement for detecting and preventing the falsification of a signal fed in the taximeter (1) of a vehicle and coming from a sensor (2) measuring the distance travelled by said vehicle. The pulse widths of the pulse signal (P) received by the taximeter are measured (103), a key number (KA) of the pulse widths of a predetermined pulse set is defined (105,106,107), relative changes in the key numbers of the pulse widths of a successive pulse sets are calculated (109), and the changes are compared (111,119) with predetermined limit values (B,C) for detecting a deceit pulse signal. As a result of said comparison, a deviation from the allowed limit value is interpreted as a presence of a deceit pulse signal (P h ), on the basis of which the falsification and a consequent fraud is prevented (129), and an alarm signal indicating fraud is advantageously given.
