Claim 0:
1. A method for controlling a vehicle comprising a drivetrain, the drivetrain comprising a drive device adapted to generate mechanical power, the method comprising:
controlling the vehicle to perform a mission comprising a plurality of stages,
collecting operational data relevant to the operation of the drivetrain, wherein the operational data indicate a de-rate of a component of the drivetrain, a fault of a component of the drivetrain, and/or an environmental condition which influences the drivetrain operation, wherein the operational data, relevant to the operation of the drivetrain, is collected during the mission, and
determining an expected mission stage,, wherein the method further comprises:
determining, in dependence on the operational data, the propulsive capacity in at least two different operational areas of the drive device, the operational areas being defined by respective different intervals of a rotational speed of the drive device,
mapping the operational area propulsive capacities to the expected mission stage,, wherein said mapping comprises comparing the operational area propulsive capacities to respective capacity threshold values of the operational area propulsive capacities in the expected mission stage, wherein each capacity threshold value provides a lower limit of the respective operational area propulsive capacity in the expected mission stage, and
controlling the vehicle in dependence on said mapping.
