CONSTITUTION: A method for controlling downshift from a second speed to a first speed comprises the steps of deciding the output of a power-off downshift control signal(S100), deciding the output of a brake switch on signal(S110), deciding if turbine RPM(Nt) and output shaft RPM(No) are zero(S120,S130), deciding the stoppage of a vehicle(S140), outputting a solenoid valve driving signal to a drive unit to engage a shift range to a first speed if a vehicle is stopped over a reference time(S150), and outputting a solenoid valve on/off driving control signal to the drive unit to disengage a second speed after the predetermined time is elapsed(S160). According to the value on/off driving control signal, a second brake solenoid valve is turned on to unengaged the second speed gear ratio. Therefore, the torque change of the output shaft is minimized.

Abstract: PURPOSE: A connecting clutch of a first speed transmission of forward moving during a backward moving is connected smoothly without a severe rocking or a connection shock to stabilize a transmission. CONSTITUTION: A driving state sensing member(10) receives signals variable by the driving state of the automobile, and outputs a corresponding electrical signal. A control member(20) receives the outputted signal of the driving state sensing member(10). If a transmission control signal while forward-moving first speed transmission during a rear moving is outputted, the control member(20) feedback controls a turbine rotation changing rate to converge to an object turbine rotation changing rate. When the rotation change of the turbine changes from a forward direction to a backward direction by an increase of a corresponding torque of the connecting side, the turbine rotation change rate is multiplied with a minus value after the turbine rotation change rate changes from a minus value to a plus value to feedback control the connection side clutch. A driving member(30) connects the connection side clutch according to a duty control signal outputted by the control member(20).

Abstract: PURPOSE: A controlling method of an automatic transmission controls a release side friction factor with a lower hydraulic pressure in a power on up shift speed change in a running car. CONSTITUTION: A controlling method of an automatic transmission comprises 5 sections. The first section outputs a power on up shift duty controlling signal, if a power on up shift speed change controlling signal in running car is approved. The second section compares and judges that the number of a turbine rotation detected according to the power on up shift duty controlling signal outputted at the first section. The third section controls a duty with an open roof until a turbine variation ratio diminishes than zero. The fourth section controls a feedback duty. The fifth section finishes a feedback duty control and a duty control if the turbine variation ratio is zero. Therefore, the controlling method of an automatic transmission prevents a run-up shock, thereby increasing a riding sense.

Abstract: PURPOSE: A gearshift control method executes gearshift immediately on power on downshift occurs when power on downshift control occurs during upshift to improve gearshift responsiveness and gearshift quality. CONSTITUTION: A control method comprises four steps. The first step(S100, S110, S120, S130, S140) is to output preset n+1 speed duty control signal to execute gearshift when n→n+1 speed upshift signal is impressed during running on n speed. The second step(S150) is to compare and determine whether power on downshift signal is impressed during n→n+1 upshift. The third step is to determine whether the power on downshift signal is a skip shift signal when the power on downshift signal is determined impressed and to execute n+1 speed upshift control when the power on downshift signal is not impressed. The forth step is to execute power on n+1→n-1 speed skip down control when the power on downshift signal is the skip shift signal and to execute power on n+1→n speed downshift control when the power on downshift signal is not the skip shift signal.
