Abstract:
1. A hydraulic pressure supply control apparatus provided in an automobile that performs internal combustion engine automatic stop control in which driving of an internal combustion engine is stopped in a case in which a predetermined internal combustion engine automatic stop condition is established, the hydraulic pressure supply control apparatus comprising: a friction engaging unit including a startup friction engaging element; a hydraulic pressure control unit for hydraulic pressure adjustment that is connected to the friction engaging unit via a first hydraulic pressure passage; a hydraulic pressure supply source that supplies hydraulic pressure for engaging the startup friction engaging element; a shunt hydraulic pressure supply passage that directly supplies hydraulic pressure from the hydraulic pressure supply source to the friction engaging unit without causing the hydraulic pressure to pass through the hydraulic pressure control unit; and a valve mechanism closing portion that, when the internal combustion engine automatic stop control is executed, forcibly causes at least one of a plurality of existing valve mechanisms respectively included in the friction engaging unit and the hydraulic pressure control unit to enter a closed state so as to suppress a flow of hydraulic oil from the hydraulic pressure supply source into the hydraulic pressure control unit via the friction engaging unit.
