The invention relates to a method for assessing a drivers braking of a vehicle, comprising determining when a braking cycle begins determining the time tengbrake when the vehicles engine brake is used during the braking cycle determining the time tshift for gear changes during the braking cycle determining when the braking cycle ends determining the total time ttotal for said braking cycle processing ttotal and tengbrake with respect to tshift according to predetermined rules, and calculating a braking assessment value BA based on processed values for tengbrake and ttotal. The invention relates also to a system for assessing a drivers braking of a vehicle.
