摘要： A shift control system for an automatic transmission. The shift control system includes an oil temperature sensor, a hydraulic controller to operate a hydraulic clutch, and a control unit in operative communication with the oil temperature sensor and the hydraulic controller. When a gear shift is requested just after an engine restart, the control unit controls the hydraulic clutch with an adjusted shift control process, in contrast to a normal condition of the engine. This adjustment is determined based on a first oil temperature at a time point when the engine is last stopped and on a temperature difference between the first oil temperature and a second oil temperature at a time point when the engine is last restarted after the last engine stop.

摘要： A transmission control system, includes:1) a high speed side friction element for establishing a high speed side change gear; and2) a low speed side friction element for establishing a low speed side change gear.After a disengagement of the high speed side friction element, the low speed side friction element makes an engagement for carrying out a downshift from the high speed side change gear to the low speed side change gear.When the downshift is carried out with an accelerator turned off, a stepping on the accelerator sensed in a period between the following times: i) a time for commanding a start of a transmission, and ii) a time for the low speed side friction element to start a conveyance of a torque, prevents a changeover to the low speed side change gear, thus keeping the high speed side change gear.

摘要： A speed change control method and apparatus for a vehicular automatic transmission having a first-speed clutch for establishing a first speed and a second-speed clutch for establishing a second speed, includes subjection of at least a duty ratio Dr of a second-speed solenoid valve for supplying oil pressure to the second-speed clutch to feedback control, so that the first-speed clutch is engaged while disengaging the second-speed clutch. This thereby increases a turbine rotational speed Nt toward the first-speed synchronous rotational speed. Further, an upper limit value Dmax of the duty ratio Dr is set, and the duty ratio Dr is subject to feedback control within a resultant duty ratio range. This thereby prevents the duty ratio Dr from being set at an excessive value caused by a delay in the rise of the oil pressure. As a result, even if a depression of an accelerator pedal is suddenly increased during a downshifting process, an interlock problem can be prevented, thereby ensuring smooth speed change.

摘要： During downshift operation of an automotive automatic transmission in which a lower-speed clutch for establishing a lower-speed gear is engaged while a higher-speed clutch, which has established a higher-speed gear, is disengaged, to increase the turbine rotational speed Nt toward a synchronous rotation speed Ntj associated with the lower-speed gear, speed change control is carried out according to the same control method regardless of whether the engine is in a power-on or power-off state. A target change rate (Nir)' of turbine rotational speed associated with the higher-speed clutch and a target change rate (Nia)' of turbine rotational speed associated with the lower-speed clutch are set, and a change rate (Nt)' of the turbine rotational speed is detected. The transmission torque through the higher-speed clutch is controlled in a feedback manner such that the detected change rate (Nt)' coincides with the change rate (Nir)', and also the transmission torque through the lower-speed clutch is feedback-controlled such that the change rate (Nt)' coincides with the change rate (Nia)', thereby carrying out downshift.

摘要： A speed change control method and apparatus for an automotive automatic transmission includes a controller, which selects a shift pattern in which shift lines are set as a function of both throttle opening and vehicle speed when the temperature of operating oil of the transmission is higher than a predetermined temperature, and selects a shift pattern in which shift lines are set as a sole function of the vehicle speed when the operating oil temperature is lower than or equal to the predetermined temperature. The controller refers to the selected shift pattern, and determines a gear to be established, in accordance with a corresponding one or both of the vehicle speed and the throttle opening detected by sensors, to thereby reduce the frequency in occurrence of shift shock when the operating oil temperature is low.
