摘要： A control device for an automatic transmission includes a continuously variable transmission mechanism, a torque converter, a target transmission ratio calculation unit, a feedback control unit, and a phase compensation unit. The torque converter has a lock-up clutch. The target transmission ratio calculation unit is configured to calculate a target transmission ratio based on a travelling state. The feedback control unit is configured to perform feedback control based on an actual value indicative of a state of the continuously variable transmission mechanism. The phase compensation unit is configured to perform phase lead compensation of the feedback control based on the travelling state. The phase compensation control unit is configured to halt the phase lead compensation when an unstable travelling state of a vehicle is detected. The phase compensation control unit is further configured to release the lock-up clutch when the phase lead compensation is halted.

摘要： An automatic transmission for a vehicle drivetrain includes a transmission housing, an input shaft, an output shaft, and a plurality of gears within the transmission housing. The plurality of gears defines multiple mechanical gear ratios between the input shaft and the output shaft. The transmission further includes a plurality of clutches operable to selectively engage the multiple mechanical gear ratios, and a plurality of rotational speed sensors. Each rotational speed sensor is operable to measure rotational speeds relative to the transmission housing for of one of the input shaft, the output shaft, or one of the plurality of gears. The transmission further includes a transmission control system configured to receive signals representing the measured rotational speeds from the plurality of rotational speed sensors and control the plurality of clutches to change between gear ratios based at least in part on the signals representing the measured rotational speeds.

摘要： A method of detecting a failure of a hydraulic pump includes sensing a rotational speed of the engine, and a rotational speed of a rotating drivetrain component. A numerical difference between the rotational speed of the engine and the rotational speed of the rotating drivetrain component is calculated. The numerical difference is compared to a threshold value to determine if the numerical difference is less than the threshold value, or is equal to or greater than the threshold value. A failure of the hydraulic pump is identified when the numerical difference between the rotational speed of the engine and the rotational speed of the rotating drivetrain component is equal to or greater than the threshold value, and the transmission is positioned in the neutral gear mode. When a failure of the hydraulic pump is identified, the operation of the engine is stopped.

摘要： A method of operating a transmission (1) with at least one interlocking shift element (F) having at least two shift element halves that can be brought into interlocked engagement with one another. When a command is received to close the interlocking shift element (F), a current rotational speed difference between the shift element halves of the interlocking shift element (F) and the current positions of the shift element halves are determined. If the rotational speed difference is smaller than a first speed difference threshold value and if a tooth-on-tooth position has occurred at the interlocking shift element (F), then to release the tooth-on-tooth position, the actuation force is changed to a release level at which a rotational speed difference above a second speed difference threshold value is produced between the shift element halves.

摘要： The present invention provides a control device for a vehicular drive apparatus with a structure of enabling the suppression of gearshift shock occurring during concurrent shifting executed of a first shifting portion and a second shifting portion. When the concurrent shifting are executed around the same time in which a down shift in one of a differential portion (first shifting portion) and an automatic shifting portion (second shifting portion) and an upshift in the other of them are executed, a first electric motor is caused to control a rotation speed of a second rotary element (sun gear). Thus, a shifting progress state upon the concurrent shifting is controlled. This causes shifting directions i.e., variation of the engine rotation speed in shifting of a shifting mechanism to be set in a unidirectional, enabling the suppression of gearshift shock.
