Abstract
A method and a system for estimating a weight mv for a vehicle on the basis of at least two forces which act upon the vehicle, the forces are a motive force FT and at least one further force, and topographical information for a relevant section of road. The estimation is performed when the at least two forces are dominated by the motive force FT.
Claims21
A method for estimating a weight mv for a vehicle comprising:
- measuring at least two forces which act upon the vehicle, the two forces comprising a motive force FT of the vehicle and at least one further force, the estimation is based on a further force relating to topographical information for a relevant section of a road on which the vehicle is moving, wherein the at least one further force comprises at least one of several forces FG related to gravitation, and the estimation takes into account said at least one or several forces FG related to gravitation and the estimation is performed when the at least two forces are dominated by the motive force FT.
A system for estimating a weight mv for a vehicle on the basis of
- at least two forces which act upon the vehicle, the forces comprising a motive force FT and at least one further force;
- wherein the system is configured to base the estimation on topographical information for a selected relevant section of a road of travel of the vehicle;
- wherein the at least one further force comprises at least one force FG related to gravitation;
- and
- the system comprises a device configured for comparing the motive force FT and the at least one further force and the system is further configured, when the system is performing the estimation, to take into account the at least one or several forces FG related to gravitation and the system performs the estimation when the at least two forces are dominated by the motive force FT.
