Abstract: PURPOSE: A shift control method of an automatic transmission and its method are provided to improve the shifting feeling by compensating hydraulic pressure after the shifting with making an engine torque into account. CONSTITUTION: In detecting a shifting demand, a shifting to a target gear is performed through a duty control(S102,S103). In finishing the shifting, a recover time of a set engine torque is counted and another shifting demand is checked during the counting(S104,S105,S106). In detecting the shifting demand during the counting, a passing time of the counter is calculated(S108). A shifting to a target gear is performed by calculating a compensating value of hydraulic pressure from the passing time of the counter(S110). Thereby, the generation of shifting shock is eliminated by minimizing the effect of a torque reduction control.

CONSTITUTION: A transmission control unit detects RPM of a turbine at the input part of a transmission and vehicle speed such as RPM of the output part in selecting 2-range during shifting from 3-range to L-range(S110-S120). A shift signal is output to downshift from 3-range to 2-range in case of the calculated value to be similar to the 3-range in dividing the RPM of the turbine by the vehicle speed(S130-S140). The RPM of the turbine is decided to be similar to the 1-range with passing the 2-range in case of the calculated value to be between the 2-range and the 1-range in dividing the turbine RPM by the vehicle speed, and a shifting signal is output to upshift from the 1-range to the 2-range(S150-S160). Shifting to the 2-range is decided, and the duty control is finished in case of the value to approach the 2-range synchronous point(S170-S180). Shift shock is prevented with controlling shifting according to the turbine RPM and the vehicle speed.

Abstract: PURPOSE: A shock control method in shifting from the 4-range to the 3-range is provided to prevent shock by adjusting the fill time with learning controlling in shifting from the 4-range to the 3-range through overdrive-off. CONSTITUTION: RPM(Revolution Per Minute) of an input shaft is differentiated according to time(S10), and the differential value is detected to be less than zero after shifting from the 4-range to the 3-range within the range of the predetermined time(S20). Fill time is reduced for optimal control in case of the differential value within the range of the predetermined time to be less than zero after shifting from the 4-range to the 3-range(S30). Total shifting time is detected to be longer than the predetermined time(400msec) in case of the differential value within the range of the predetermined time to be over zero after shifting from the 4-range to the 3-range(S40). Fill time is increased in case of total shifting time to be longer than the predetermined time(S50), and is kept in case of total shifting time to be shorter than 400msec(S60). Shift shock is reduced, and responsiveness is improved in shifting from the 4-range to the 3-range.

Abstract: PURPOSE: A method for controlling shift at a low oil temperature is provided to reduce a run-up shock caused by the low oil temperature in up-shift from the second range to the third range in an automatic transmission. CONSTITUTION: A shift control instrument decides output of a power on up-shift control signal from the second range to the third range. After operating a fill time, the shift control instrument a duty control signal by using initial duty value, duty inclination, and duty output time in an up-shift map to a driving instrument. The shift control instrument detects rpm(revolutions per minute) of a turbine. The shift control instrument outputs a duty control signal by establishing the duty inclination for 10% to the driving instrument. In case of the rpm of the turbine over the second-range gear ratio, a run-up is decided for calculating a duty drop amount. A duty compensation is performed by using the duty drop amount and a present duty value. After establishing the duty inclination as 30%, a duty control signal is outputted to the driving instrument. By deciding an up-shift point from the second-range to the third-range, the duty inclination is returned to 10%. The shift control instrument decides completion of shift for outputting the duty control signal to the driving instrument.
