  • Hydraulic control system for an automatic transmission
    Patent number: 6832977
    Abstract: The hydraulic control system includes a driving condition detection unit, a transmission control unit, and a driving unit. The driving condition detection unit detects driving conditions of a vehicle. The transmission control unit performs variable line pressure control using a minimum line pressure and a line-pressure-decreasing gradient calculated based on driving condition data detected by the driving condition detection unit when the driving conditions satisfy variable line pressure control entrance conditions. The driving unit adjusts a duty ratio of line pressure applied to friction elements according to a line pressure control signal generated by the transmission control unit.
