The invention relates to a method for determining a remaining travel distance available on remaining amount of propellant (DTE) of a motor vehicle (100), comprising the steps of: - determining (s310) remaining amount (Vol) of propellant; - determining (s310) current vehicle speed (V); - determining (s310) current propellant consumption; - determining (s320) a routine measurement (Measured DTE) of remaining travel distance available on remaining amount of propellant (DTE) on the basis of the parameter values thus determined with respect to remaining amount (Vol) of propellant, current vehicle speed (V) and current propellant consumption; - continuously (s330) determining travel distances (S*Ts) during said determination as a basis for a corrected measurement (Process DTE(n)) of remaining travel distance available on remaining amount of propellant; - determining (s340) said corrected measurement (Process DTE(n)) on the basis of a previously determined adjusted measurement (Final DTE(n-1)) of remaining travel distance available on remaining amount of propellant, with subtraction of a determined travel distance (S*Ts) from the previously determined adjusted measurement (Final DTE (n-1)); - determining (s350) an adjusted measurement (Final DTE(n)) as the aggregate of a corrected measurement (Process DTE(n)) and a weighted magnitude representing a difference between said routine measurement (Measured DTE) and said corrected measurement (Process DTE(n)). The invention relates also to a computer programme product comprising programme code (P) of a computer (200; 210) for implementing a method according to the invention. The invention also relates to a system for determining a remaining travel distance available on remaining amount of propellant (DTE) on board a motor vehicle and to a motor vehicle (100) equipped with the system.
