A system for providing an automated axial force to a continuously variable transmission (CVT) in a wheelchair. An electronic transmission control receives one or more input signals generated by throttle position or other variables. The microprocessor generates an output signal that adjusts the axial force applied to a CVT thereby automatically adjusting the input to output ratio. The invention also provides a manually-controlled variator is designed for use on a wheelchair. The manual shifter hydraulically adjusts an axial force imparted on a variator in communication with a wheelchair wheel and a hand rim. Application of the axial force causes the hand rim input and wheelchair wheel output ratio to change, permitting a wheelchair operator to manually adjust the input to output ratio to more easily operate the wheelchair.

In an automatic transmission, a shift lever is operable to move to one of a plurality of shift positions corresponding to ranges established as selectable options. The plurality of shift positions are each configured as one of a momentary position allowing the shift lever to automatically return to a home position and a retention position allowing the shift lever to be held therein. A return mechanism for causing the shift lever held in the retention position to return to the home position is provided. The return mechanism is enabled on one of conditions that the parking switch be turned on and that an ignition switch be turned off. In a manual transmission, a return mechanism for causing the shift lever held in a gear stage to return to a home position is provided, and the return mechanism is enabled on condition that an ignition switch be turned off.

A parallel manual transmission for a four-wheel drive is provided and includes two input shafts, each of which can be non-rotatably coupled via its own clutch to a shaft that is powered by a drive engine.

A control apparatus for a continuously variable transmission for use with a vehicle is provided for permitting a driver to select one from three transmission modes for the continuously variable transmission, and providing an appropriate transmission ratio in accordance with a particular operating condition of a vehicle without causing an insufficient engine torque or over-revolution, particularly when the transmission is switched from a continuously variable transmission mode to a stepped manual transmission mode. The control apparatus comprises an ECU and an MT switch. The ECU executes a continuous automatic transmission mode for continuously setting a transmission ratio of the continuously variable transmission in accordance with a detected operating condition of the vehicle. The ECU also executes a stepped automatic transmission mode for setting the transmission ratio of the continuously variable transmission to one of a plurality of predetermined transmission stages in accordance with the detected operating condition of the vehicle. The CPU further executes a stepped manual transmission mode for setting the transmission ratio to one of a plurality of predetermined transmission stages in accordance with a driver's intention of transmission. The ECU sets the continuously variable transmission to one of the continuous automatic transmission mode, the stepped automatic transmission mode and the stepped manual transmission mode in accordance with a manipulating state of an MT switch.

An engine control system transitions between activated and deactivated modes in a vehicle equipped with a manual transmission. The engine control system includes a clutch plate position sensor and a shifter shaft position sensor in communication with a controller. The controller determines if conditions to increase or reduce the number of active cylinders based on data collected from the position sensors, engine speed, and manifold absolute pressure. Prediction of the driver's next movements is the basis of the control. The sensors provide the history, averages, acceleration data, and velocity data, which lead to the driver's intent.

The present invention relates to compositions comprising at least one triazole-containing species and at least one thiadiazole-containing species, which in embodiments are suitable for manual transmission oils.

A shift control method for an automated manual transmission is provided. The method includes the step of modulating the force applied to a shift collar, via a shift rod and / or shift fork for example, during the engagement of the shift collar and a selected gear. The method modulates the initial engagement force applied to the shift collar when the rotational speed differential between the collar and gear is being adjusted, before increasing the force again following modulation. This modulation of the force decelerates the shift collar during the rotational speed adjustment and does not accelerate the shift collar to complete the engagement until after the modulation. In this way, a less abrupt engagement of the gear may be achieved. The control method may improve the driving characteristics of the vehicle employing the transmission and may also improve the power transmission efficiency.

A hybrid drive manual transmission, for a motor vehicle, having two input shafts (GE1, GE2) and one common output shaft. The first shaft (GE1) can connect with a combustion engine drive shaft and can drive the output shaft via a first group of gearwheel sets. The second shaft (GE2) can connect with an electric machine and, via a second group of gearwheel sets, the output shaft. The input shafts (GE1, GE2) can connect with one another via a coupling device. For inexpensive production, the transmission is derived from a double clutch transmission having a hollow input shaft (GE2) and a coaxial inner input shaft (GE1) and a coupling device of which comprises a gear step and / or a shiftable clutch, which replaces that gearset and associated gear clutch. The gearset of the underlying double clutch transmission is allocated to first input shaft (GE1) and adjacent the gear-side end of shaft (GE2).
