Lubrication control device for automatic transmission

PURPOSE: To improve the fuel consumption enhance the lubricating ability through reduction in lubricating oil amount by distributing lubricating oil from a lubricating oil pressure source into a clutch system and a brake system through independent oil paths, and feeding lubricating oil to the brake system only when it must be cooled. CONSTITUTION: A lubricating oil distribution means (c) to an input port (b) of which a lubricating oil pressure source (a) is connected is provided, and a clutch system lubricating oil path (g) for feeding lubricating oil to rotating parts (e) such as clutch, etc., by oil injection from the outer periphery of a transmission shaft (f) is connected to a first output port (d) of the lubricating oil distribution means (c). Also, a brake system lubricating oil path (k) for feeding oil to a transmission case (j) is connected to a second output port (h) of the lubricating oil distribution means (c) to feed lubricating oil to a brake (i) by oil injection from the upper side of the case. Then the lubricating oil distribution means (c) outputs a control instruction for distributing lubricating oil at least when the brake (i) must be cooled from a lubricating oil distribution control means (m) to a brake system lubricating oil path (j) to cool the brake (i).
