Abstract: A method of searching for a sync start in an automated manual transmission includes manual transmission mechanism operated using an actuator. This method can accurately search for a sync start that acts as an important reference for the control in a shift operation so that the sync start can be used for the control of the actuator, which improves shifting response and reduces the chance of a shifting impact occurring, thereby obtaining a high quality of shifting in a reliable fashion.

Abstract: An engine speed synchronizer for a manual transmission with an engine clutch, synchronizes rotation of the engine side of the engine clutch with rotation of the transmission side of the engine clutch by engine speed control with reference to operation of a shift lever under condition that the engine clutch is disengaged. The engine speed synchronizer determines whether or not a transmission input speed has started to change in a direction conforming to the operation of the shift lever; permits the synchronization in response to determination that the transmission input speed has started to change in the conforming direction; and inhibits the synchronization in response to determination that the transmission input speed has not started to change in the conforming direction.

Abstract: A control system includes a pressure control solenoid and a flow control solenoid having an input in fluid communication with the pressure control solenoid. A piston adjusts a position of a shift fork and includes a first area in fluid communication with the pressure control solenoid and a second area in fluid communication with the flow control solenoid. A fork sensor senses a position of a shift fork. A slip sensing module estimates slip acceleration between an input shaft and a gear. A flow determining module generates a flow command for the flow control solenoid. A sync control module determines a slip acceleration profile including an estimated slip acceleration, adjusts the estimated slip acceleration based on the measured slip acceleration, and generates a pressure command for the pressure control solenoid based on the adjusted slip acceleration.

Abstract: A shift control device of a vehicular automatic transmission that establishes a plurality of gear steps of different speed change ratios by selectively engaging a plurality of friction engagement devices ends the shift control by making an engagement end determination regarding an engagement-side friction engagement device if it has been determined continuously for a predetermined time that the input shaft rotation speed of the automatic transmission is in the vicinity of the synchronous rotation speed of the post-shift gear step. The predetermined time is set at a first time if the downshift is a power-on downshift due to a shift judgement in a power-on state, and is set at a second time that is shorter than the first time if the downshift is a power-off→on downshift selected in connection with a change to the power-on state during a power-off shift due to the shift judgment in a power-off state.

Abstract: The present invention relates to a shift sequence control to coordinate shifting, which corresponds to changes of constellations in a transmission. A change of the constellations yields a change of the force transfer of the transmission. The sequence of shifting takes place program-controlled and is subdivided into phases (0, 1, 2, 3, 4, 5, 6, 7). The sequence includes the driving of a plurality of actuating elements and each of the phases is assigned at least one type of drive for at least one actuating element.According to the invention, it is provided that the phases (0, 1, 2, 3, 4, 5, 6, 7) can be configured without changing the program.Furthermore, the present invention relates to a method for coordinating shifting sequences.

Abstract: When it has been determined that control for a predetermined upshift has been started while an accelerator pedal was not being depressed, and that a factor that changes an input torque of an automatic transmission has been generated, an engaging pressure of a predetermined hydraulic frictional engagement device is corrected by a correction amount in accordance with the factor that changes the input torque. As a result, undershooting of an engine speed, as well as shift shock which results from that undershooting, is able to be preferably suppressed.

Abstract: In a hybrid vehicle, rotational speed control on a motor/generator connected to a first engagement clutch is carried out when there is a gear shift request to a gear shift stage at which the first engagement clutch of the multistage gear transmission is meshingly engaged. A transmission control unit is provided for outputting a meshing engagement instruction to the first engagement clutch when a rotational speed feedback control causes a differential rotation speed of the first engagement clutch to be within a range of a synchronization determination rotational speed. Upon executing the rotational speed feedback control on the motor/generator, this transmission control unit reduces the efficacy of the rotational speed feedback control less than before starting of the meshingly engagement, when the meshing engagement of the first engagement clutch is started.

Abstract: When a synchronizing sleeve that is driven by an actuator in response to gear shift request is stroked from a release position to an engagement position, a differential rotation speed between an input rotation and an output rotation is calculated at stroke positions after a synchronization completion position; and when the said differential rotation speed is equal to or more than a predetermined threshold value, a damage determination index is calculated based on the said differential rotation speed. Further, when a cumulative value of the damage determination index accumulated for each gear position becomes equal to or more than a predetermined threshold value, the engagement operation of the gear position corresponding to the said cumulative value is disabled. This makes it possible to effectively determine the degree of damage when a gear whine occurs to a synchronized engaging device.
