Abstract:
1. A method for provisional determination of a mass of a vehicle ( 1 ) on initialization, in which the vehicle ( 1 ) comprises a control unit ( 2 ) which, on a basis of dynamic movement data of the vehicle ( 1 ), determines a current vehicle mass value, and the control unit storing a last dynamically determined vehicle mass value in a data memory ( 12 ) when the control unit ( 2 ) is de-initialized, and either on or immediately after the initialization of the control unit ( 2 ), the control unit ( 2 ) reads in the last-determined dynamic vehicle mass value stored in the data memory, the method comprising the steps of: storing the last dynamically determined vehicle mass value in the data memory ( determining an axle load of at least one rear axle of the vehicle ( determining a statically determined vehicle mass value on a basis of the last dynamically determined vehicle mass value; comparing the statically determined vehicle mass value with the last dynamically determined vehicle mass value; adopting the statically determined vehicle mass value as the relevant vehicle mass value, if the statically determined vehicle mass value differs by more than a predetermined tolerance range from the last dynamically determined mass value; and defining the relevant vehicle mass value as the last dynamically determined vehicle mass value, if the statically determined vehicle mass value is within the predetermined tolerance range.
