摘要： A shift-by-wire system (10) improves responsiveness to a shift command and ensures safety. An electric motor (24) generates a rotational output to be used to switch the ranges of an automatic transmission (16). A by-wire control circuit (2) electrically controls the rotation of the electric motor to comply with an inputted shift command. If a re-shift command is inputted during switching control, the by-wire control circuit modifies rotation control. The modification can be implemented until the rotational position of the electric motor reaches a new target rotational position to comply with the re-shift command.

摘要： The control apparatus includes a so-called pre-shift means. The pre-shift means operates a predetermined synchromesh 21, 22, 23 based on a result of prediction by a predicting means. It thereby couples together a transmission input shaft 41, 42 with which a friction transfer mechanism having not been used for achievement of a current gear position and a transmission output shaft 43 through a predetermined gear train and brings them into standby state. As the timing with which the synchromesh 21, 22, 23 coupling operation by the standby control is started, the time when it is determined that the friction transfer mechanism having not been used for the achievement of the current gear position has been disengaged is taken regardless of the completion of the achievement of the current gear position.

摘要： The invention relates to a method for carrying out shifting operations for the automatic transmission of a motor vehicle, in particular overlapping shifting operations, for which a first shifting element opens and a second shifting element closes during a shifting operation. To increase the spontaneity and to reduce the shifting frequency, a downshift from a first ratio stage (i1) to a second ratio stage (i2) is interrupted immediately and returned to the first ratio stage (i2), if an interruption criterion is recognised. The interruption criterion is set if a stipulated request by a driver of the motor vehicle for an upshift is recognised before a current transmission input speed (n_T) deviates from a synchronous speed of the first ratio stage (i1), or before a time phase that commenced with said deviation from the synchronous speed of the first ratio stage (i1) has exceeded a predefinable time-based threshold value, or before the current transmission input speed (n_T) has deviated from a synchronous speed of the first ratio stage (i1) by a predefinable, speed-based threshold value, or before a pressure (p_K1) of the deactivating first shifting element falls below a predefined, pressure-based threshold value.

摘要： At downshifting, hydraulic pressure of hydraulic clutch on engaging side (ON clutch pressure) is increased when an input and output speed ratio ("Gratio") has fallen below a predetermined value YGDNS. YGDNS is variably set depending on the vehicle speed and the engine temperature so that it becomes a lower value at a high vehicle speed than at a low vehicle speed, and a higher value at a low engine temperature than at a high temperature. When a downshifting command to a still lower speed stage is issued during downshifting control (when FTBD=1), a downshifting completion processing is performed in the course of the downshifting control (step in S111). Oil pressure in a hydraulic engaging element on the disengaging side QDNOFF and oil pressure in a hydraulic engaging element on the engaging side QDNON are switched to the oil pressures at the time of completion of downshifting, to thereby complete the first step downshifting control at an early time. In order to prevent unnecessary speed changing at the time of tire locking, downshifting is prohibited when deceleration of the vehicle speed has exceeded a predetermined value (when a setting of FLOCK=1 is made).
摘要翻译：在降档时，当输入和输出转速比（“Gratio”）已经下降到预定值YGDNS以下时，接合侧液压离合器的液压（ON离合器压力）增加。 YGDNS根据车速和发动机温度可变地设定，使得它在高车速下比在低车速下降低，在低发动机温度下比在高温下更高。当在降档控制期间（当FTBD = 1时）发出向较低速级的降档指令时，在降档控制的过程中执行降档完成处理（步骤S111）。分离侧的液压接合元件中的油压QDNOFF和接合侧的液压接合元件QDNON中的油压在换档完成时切换到油压，从而在早期完成第一级降档控制时间。为了防止在轮胎锁定时不必要的速度变化，当车速的减速超过预定值（当设定为FLOCK = 1时），禁止降档。

摘要： A shift control system for an automatic transmission having an automatic shift mode in which a proper gear ratio is automatically selected according to a shift command based on a throttle valve opening and a vehicle speed, and further having a manual shift mode in which a gear ratio is selected according to a shift command given by driver's manual operation. The shift control system includes timer means for counting an elapsed time after a shift operation has been started. The elapsed time is compared with a predetermined first re-shift permission time in the case of automatic shift operation and with a predetermined second re-shift permission time in the case of manual shift operation. The first re-shift permission time and the second re-shift permission time are different from each other to optimize the shift control both in the automatic shift mode and in the manual shift mode.
