Hierarchical Vehicle De-Rate and Notification System

A computer-implemented method comprising:

• detecting a condition of a vehicle;
• identifying a de-rate cause for the vehicle from a hierarchical set of de-rate causes, wherein the de-rate cause is associated with the detected condition;
• selecting a de-rate type from a set of possible de-rate types based at least in part on the identified de-rate cause;
• selecting an initial de-rate level from a set of possible vehicle de-rate levels based at least in part on the identified de-rate cause;
• presenting an operator notification associated with the detected condition via an operator interface on board the vehicle;
• and
• imposing a de-rate on the vehicle based at least in part on the de-rate type, the initial de-rate level, and a slew rate.

An on-board vehicle computer system comprising:

• at least one processing unit;
• and
• a memory having therein computer-executable instructions configured to cause the on-board vehicle computer system 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 condition;
• and
• update the initial de-rate level based at least in part on the change in the condition.
