The invention comprises an engine-driven auxiliary system for a motor vehicle. At least two auxiliaries are coupled in rotation with the crankshaft of the vehicle engine by transmission means. These auxiliaries include auxiliaries which constitute a hierarchic group with an order of operational priority in which at least one of the auxiliaries takes precedence over at least one other of the auxiliaries. The state of an economizer element varies concomitantly with the working conditions of the auxiliary having the higher priority, and is adapted to put the auxiliary with the lower priority at least partly out of action when the working conditions of the higher priority auxiliary exceed a predetermined threshold. |
