摘要： A controller for automatic transmission that performs feedback control on a slip ratio of a lockup clutch is adapted to select one target slip ratio from a plurality of target slip ratios based on a detected automatic transmission fluid temperature of a torque converter. Thus, the controller can ensure good followability to a target value of the feedback control even when the automatic transmission fluid temperature is low. The controller can effectively prevent engine hunting and the associated vibrations of vehicle body. Therefore, the controller can accomplish a favorable slip control of the lockup clutch even if an operating range of the lockup clutch is expanded to a range where the automatic transmission fluid temperature is low.

摘要： A controller for a transmission capable of preventing an occurrence of a gear squeak caused by a malfunction of a synchronization mechanism. The voltage determination section 24 performs a shift operation of a transmission by determining a control input Vin to a shift motor 13 so as to match an actual position Psc of a coupling sleeve 6 grasped by an actual position grasping section 21 with a target position Psc_cmd of the coupling sleeve 6 set by a target position setting section 22. After starting the shift operation of the transmission, it halts the shift operation by detecting a malfunction in the gear position where the shift operation is under execution when the actual position Psc of the coupling sleeve 6 has reached a malfunction judgment position provided within a range from a balk point to a contact point between the coupling sleeve 6 and an idle gear 7c before a difference Esc between the actual position Psc and the target position Psc_cmd of the coupling sleeve 6 exceeds a given contact judgment value.

摘要： The power transmission mechanism reliably starts an internal combustion engine that is stopped during travel of a vehicle. While the internal combustion engine is stopped and the internal combustion engine and the transmission are disengaged by the main clutch, it is determined whether the mode is the EV travel mode, corresponding to the driving mode by the electric motor. In the case of the motor driving mode, and if the vehicle speed is less than a predetermined value, the engine is started in a neutral mode. If the vehicle speed is higher than a predetermined value, the engine is started in a standby mode. When starting in the standby mode, a gear set is selected based on the vehicle speed, and the input shaft and the output shaft are engaged.

摘要： A hybrid vehicle comprises a torque converter TC, which is connected to an engine E, a gear-type speed change mechanism, shift clutches 13c and 14c, a drive power transmission system, which transmits output rotation to drive wheels 6, and a second motor generator 2, which can drive the drive wheels 6. A control system for this hybrid vehicle comprises a throttle controller TH and a shift control valve CV. When the drive mode is switched from motor-driven mode to engine-driven mode, the control system sets a target speed ratio and calculates a vehicle-speed corresponding rotational speed that would arise at the output shaft of the engine if the current rotation of the drive wheels were transmitted with this target speed ratio and through the torque converter with a speed ratio of 1.0. Then, the control system controls the rotation of the engine to bring the output rotational speed of the engine closer to the vehicle-speed corresponding rotational speed. If the deviation of the output rotational speed of the engine from the vehicle-speed corresponding rotational speed becomes and remains equal to or smaller than a predetermined value for a predetermined time period, then the control system engages the frictionally engaging means to establish the target speed ratio.

摘要： A transmission comprises an engine, which is controllable to stop under a predetermined condition, and a speed change mechanism TM, which transmits the output rotation of the engine at different speed ratios. The speed change mechanism TM has a plurality of transmission paths (the LOW ratio, the SECOND speed ratio, etc.) disposed in parallel, a plurality of ratio-setting clutches (the LOW clutch 11, the SECOND speed clutch 12, etc.), each clutch for selecting a predetermined transmission path, and a speed change control system for selectively supplying a hydraulic pressure to any of the ratio-setting clutches to bring it into engagement. Engagement-initiation time is calculated for each ratio-setting clutch, so that the ratio-setting clutch requiring a minimum engagement-initiation time is selected as the clutch for the start-up speed ratio. When the engine is restarted from stopped state, this clutch for the start-up speed ratio is supplied with oil.

摘要： A low cost control apparatus of a contact mechanism resolving a disadvantage caused when a contact body is moved to make contact with a contacted body by an actuator. A synchronizing mechanism, which a coupling sleeve rotatably and integrally provided with an input shaft is pushed against a synchronizer ring disposed between the coupling sleeve and a synchronized gear, thereby synchronizing rotational speeds of both the components to engage them, is modeled as a collision between an inertia system object and an elastic system object. A computation coefficient (VPOLE, f in FIG. 9) of a switching function for sliding mode control having a deviation between an actual position of the coupling sleeve (Psc, d in FIG. 9) and a target position (Psc_cmd, e in FIG. 9) as a state variable is changed depending on the actual position (Psc), and thereby changing a control ability of the model against a disturbance.
