Abstract
An engine driven vehicle includes at least one engine, and control devices that are arranged to control a transmission that is driven by the engine. The control devices are arranged to receive at least two sets of data, each set including at least one of a first signal that includes information about the gradient of the surface on which the vehicle is being driven sent from a first sensor, and at least one second signal that includes information about the vehicle's speed sent from a second sensor, and at least one third signal that includes information about the vehicle's acceleration. The control devices are also arranged to calculate at least one of two different resistance to travel constants kand k, in response to the first, second and third signals, and to control the transmission in response to at least one of the constants kand k.
