A vehicle idle stop system is disclosed. The idle stop system comprises an engine, an automatic transmission, a first oil pump driven by said engine and generating hydraulic pressure which is supplied to a friction element of said automatic transmission, a second oil pump capable of operating and generating hydraulic pressure which is supplied to a friction element of said automatic transmission during an engine stop, and a controller. The controller is configured to control the engine to stop when a predetermined engine stop condition is satisfied, and to control the second oil pump to supply hydraulic pressure to a predetermined friction element coupled to a forward starting gear of the automatic transmission, the hydraulic pressure supplied to couple the predetermined friction element when the engine is automatically stopped and when a gear range of the automatic transmission is in a neutral range.
