摘要
The shift control system for an automatic transmission in a vehicle includes a plurality of sensors and a transmission control unit. The plurality of sensors sense operating conditions of the vehicle. The transmission control unit controls shift control solenoids and a pressure control solenoid in a hydraulic control system for the automatic transmission based on the sensed vehicle operating conditions. The shift control solenoids control operation of friction elements in the automatic transmission, and the pressure control solenoid controls hydraulic pressure supplied to the friction elements. The transmission control unit detects a change in driving mode from a reverse mode to a drive mode based on the sensed vehicle operating conditions, and controls the shift control solenoids such that the automatic transmission shifts into only a first speed stage in the drive mode when the transmission control unit detects the change in the driving mode from the reverse mode to the drive mode.
