Abstract
A method and a system for choosing a transmission mode in a vehicle over the course of a road section, wherein the vehicle has applied coasting prior to this road section and wherein a highest permitted speed vmax is defined for the road section, below which an actual speed for the vehicle should be kept. A simulation of a future speed profile vsim_Gear for a possible gear position for a gearbox in the vehicle is conducted on the basis of a road slope obtained from map data in combination with vehicle positioning information and wherein the simulation simulates, when the road section lies ahead of the vehicle, an actual speed for the vehicle over the course of the road section. Next, an evaluation is carried out of whether a suspension of the coasting in favor of the possible gear position is recommended, wherein the possible gear position is deemed recommendable if a highest value vsim_Gear_max for the future speed profile exceeds the highest permitted speed vmax. The evaluation is then utilized in the choice of transmission mode.
