Abstract

A control system (100) for an engine-driven auxiliary equipment (51) for a vehicle equipped with an automatic transmission (10) including a fluid coupling type torque converter (2) receiving power from an engine (1) to drive a driven wheel. The control system (100) is adapted to interrupt power from the engine (1) to the auxiliary equipment (51) under a condition that an instantaneous value (e.sub.d) of a gear ratio (e) as the quotient of a rotation speed (No) of an output shaft (3) of the torque converter (2) to a rotation speed (Ni) of an input shaft (2a ) of the torque converter (2) is lying in a region (e.sub.d <e.sub.c, e.sub.1, e.sub.2) corresponding to a state of torque amplification of the torque converter (2) where a predetermined value is exceeded.
