Abstract
A method and a system for controlling a cruise control and a transmission in a vehicle over the course of a road section, wherein prior to the road section, the vehicle has applied coasting and utilizes the cruise control. A reference speed vref utilized in the cruise control during the coasting is lowered to a lowest permitted speed vmin defined for the road section if the lowering is deemed applicable. A comparison of a drive force Fdd requested from an engine system in the vehicle with a threshold value Flim for the drive force is also carried out. The coasting is then suspended if the requested drive force Fdd exceeds the threshold value Flim for the drive force.
