ABSTRACT:
A method for optimizing a braking sequence in a vehicle with automatic transmission (3) and gearbox (9) and automatic cruise control, which cruise control controls acceleration and braking to achieve a set speed, taking into account the distance to the vehicle in front. Data simulations are carried out continually of how the vehicle will be driven in the future, for a set of different combinations of engine speed at which a gear change takes place, gear change step and braking sequence, and a braking sequence with associated gear change schedule is selected that will be optimal. The vehicle is equipped with at least two different braking systems, for example service brake and auxiliary brake (48, 6). The system selects to brake primarily with the braking system that has the least tendency to wear.
