| 摘要 |
<p>The present invention provides a hydraulic control system for automatic transmissions, which includes line pressure control means (10) for regulating hydraulic pressure generated in an oil pump to a line pressure level, damper clutch control means (6) for receiving the line pressure to control a damper clutch, shift control means (22) for receiving the line pressure and supplying the same according to each shift mode (S2,S3), hydraulic pressure distributing means (24,26,28,29) for receiving hydraulic pressure from the shift control means (22) and supplying the same to a plurality of friction elements (C1,C2,C3,B1,B2), and hydraulic pressure control means (14) for regulating the line pressure and supplying the same to the hydraulic pressure distributing means (18,20) to correspond to each shift mode wherein abrupt pressure exhaust preventing means (15) is provided which slows exhaust of hydraulic pressure when shifting from drive D or reverse R ranges to a neutral N range. <IMAGE></p> |
