Abstract
A control system for engine-driven vehicle accessories generates sets of values representing a recent history of the engine loading and of the operational status of the accessories. History factors are derived from the sets of values. The accessories are controlled as a function of sensed parameters and of comparisons between the history factors. The sets of values are periodically updated.
