An on-board vehicle computer system is configured to detect a condition of a vehicle; identify a de-rate cause for the vehicle in a hierarchical set of de-rate causes, wherein the de-rate cause is associated with the condition; select a de-rate type from a set of possible de-rate types based at least in part on the de-rate cause; select an initial de-rate level from a set of possible de-rate levels based at least in part on the de-rate cause; present an operator notification associated with the de-rate cause via an operator interface; activate a de-rate for the vehicle according to the de-rate type and the initial de-rate level; detect a change in the vehicle condition; and update the initial de-rate level based at least in part on the change in the vehicle condition.
