ENGINE DRIVEN VEHICLE WITH TRANSMISSION

摘要

The invention relates to an engine driven vehicle comprising at least one engine (10), control devices (45;48) that are arranged to control a transmission (90) that is driven by the engine, which control devices are arranged to receive at least two sets of data, each set comprising at least one of a first signal that comprises information about the gradient of the surface on which the vehicle is being driven (S (i) ) sent from a first sensor (115), and at least one second signal that comprises information about the vehicle's speed (V(i) ) sent from a second sensor (116), and at least one third signal that comprises information about the vehicle's acceleration (a(i)) . The invention is characterized in that the control devices are also arranged to calculate at least one of two different resistance to travel constants k
