Abstract: A hybrid gearbox has a shift gearbox including at least one fixed ratio gear having a gear ratio both for the internal combustion engine and the electric motor-generator with respect to a power train connection, and speed superposition gearbox which is designed to provide a power-split gear having a variable speed ratio and a fixed torque ratio with respect to the internal combustion engine connection and the power train connection, wherein the variable speed ratio is formed by a modulation of a speed provided by the internal combustion engine on a speed provided by the electric motor-generator. The hybrid gearbox has at least one operating mode in which gear changes are only carried out between the fixed-ratio gear and the power-split gear.

Abstract: A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing includes a single external power access for the shift actuator. A controller interprets a shaft displacement angle, determines if the transmission is in an imminent zero or zero torque region, and performs a transmission operation in response to the transmission in the imminent zero or zero torque region.

Abstract: A displayed rotation speed control apparatus for a hybrid vehicle includes: a displayed rotation speed controller having a display mode in which a target primary rotation speed stepwisely set is displayed as a driving source rotation speed in the rotation speed display device in the simulated stepwise shift mode, when the mode is switched from the EV mode to the HEV mode to initiate a starting of the engine, and when the mode is switched from the continuous shift mode to the simulated stepwise shift mode while an actual engine speed is smaller than a predetermined rotation speed, the displayed rotation speed controller being configured to display a value obtained by retarding the actual engine speed, during a period from the initiation of the starting of the engine to a rotation speed smaller than a predetermined rotation speed.

Abstract: A method of synchronizing the countershaft speed, in the direct gear, for a hybrid application. The transmission (1) comprises a main transmission (HG) comprising two parallel partial transmissions with at least one countershaft (VW), an output shaft (3), and two planetary transmissions (PG1, PG2) each comprising a carrier (ST1, ST2), sun gear (SR1, SR2) and ring gear (HR1, HR2). Each partial transmission has a transmission input shaft (4, 5), with a hollow first input shaft (4) and the solid second input shaft (5). The first planetary transmission (PG1) connects as a range group to the main transmission (HG). The main transmission (HG) comprises first (R1), second (R2), third (R3), fourth (R4) and fifth gear planes (R5) and first (S1), second (S2), third (S3) and fourth shift elements (S4). Synchronization of the countershaft speed to a target speed, in direct gear, is performed via speed control of the electric machine (2).

Abstract: In accordance with an example embodiment, a transmission may include a first mode in which a low range clutch is engaged and a first synchronizer is in a first engaged condition causing an output shaft to rotate relative to a first range shaft based upon a ratio of a first range gear to a second range gear. The transmission may include a second mode in which a high range clutch is engaged and a second synchronizer is in a first engaged condition causing the output shaft to rotate relative to a second range shaft based upon a ratio of the first range gear to the second range gear. A shift from the first mode to the second mode includes engaging the second synchronizer in the first engaged condition before disengaging the low range clutch and engaging the high range clutch.
