High efficiency, high output transmission having an aluminum housing

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.

A transmission for a vehicle includes a knob configured to be rotated to select one of a plurality of shift stages, a driving unit for controlling rotation of the knob, and a shift controller for applying an electrical current to generate a torque in the driving unit. Further, the driving unit includes a magnetic field generator, a magnetization unit including a plurality of magnetic bodies arranged at regular intervals along a circumference of the magnetic field generator, and a magnet unit including at least one pair of magnetic poles arranged along a circumference of the magnetization unit. In particular, the magnetization unit or the magnet unit is coupled with the knob and rotates integrally with the knob. Depending on an intensity of a magnetic field generated by the magnetic field generator, the driving unit allows or prevents the rotation of the knob.

Shift range control device

A shift range control device switches a shift range by controlling driving of a motor. A learning unit learns, as a position correction value, a normal state time correction value calculated based on first and/or second reference angles when an output shaft signal is available when turning on of a start switch. The first reference angle is a motor angle when the output shaft signal changes in response to the rotation of the motor in a first direction. The second reference angle is the motor angle when the output shaft signal changes in response to the motor rotation in a second direction opposite to the first direction. A motor angle target value is set by using the normal state time correction value stored during a period from when all the output shaft signals are determined to be unavailable to when the start switch is turned off.

Shift control system for automatic transmission

A shift control system for an automatic transmission is provided. The system includes a shift switch through which a manual transmission command for arbitrarily changing a gear stage of the automatic transmission can be inputted in a manual transmission mode. The manual transmission mode includes a first manual mode in which the gear stage is changed and maintained by inputting the manual transmission command using the shift switch, and a second manual mode in which an automatic transmission mode is resumed by satisfying a resuming condition after the gear stage is changed. The system includes a mode input device configured to select in advance one of the first manual mode and the second manual mode to be set, the mode input device setting to the automatic transmission mode by the selected mode being changed from the first manual mode to the second manual mode, or vice versa.

A transmission system avoids activation of a sailing functionality in a vehicle. The transmission system is configured for automatic gear-shifting in an automatic mode and manual gear-shifting by a user in a manual mode. The transmission system includes a user input device configured for manually changing the operational mode between the automatic and manual modes. The transmission system includes a transmission control unit for determining a recommended gear in the automatic and manual modes. In the manual mode, an operating gear of the transmission system is detected by the transmission control unit. A change of the operational mode from manual to automatic by means of the user input device is detected, and if the detected operating gear in the manual mode when changing to automatic mode is lower than the recommended gear, the sailing functionality in the automatic mode is deactivated.

Transmission selector for vehicles

The disclosure provides a transmission selector for a vehicle. The transmission selector for a vehicle includes: a transmission selector element including a first switch and a second switch, and a control circuit. When the vehicle speed is equal to or less than a first threshold, the control circuit switches the current gear to D in response to the selection operation received by the first switch, and the control circuit switches the current gear to R in response to the selection operation received by the second switch. When the vehicle speed is equal to or less than the first threshold and the vehicle meets the specified conditions, the control circuit controls the vehicle to switch the current gear in response to a long-press operation whose execution of the selection operation received by the first switch or the second switch reaches a first specified time.

Shift control system for automatic transmission

A shift control system for an automatic transmission is provided, which is mounted on a vehicle configured to be started by an ignition switch being turned on, where an automatic transmission mode or a manual transmission mode is selectively set. The system includes a shift switch through which a manual transmission command for arbitrarily changing a gear stage of the automatic transmission can be inputted in the manual transmission mode, and a controller. The manual transmission mode includes a first manual mode in which the gear stage is changed and maintained by inputting the manual transmission command using the shift switch, and a second manual mode in which the automatic transmission mode is resumed by satisfying a resuming condition after the gear stage is changed. When the ignition switch is turned on, the controller selects in advance the second mode to be set to the automatic transmission.

Transmission device and method of controlling transmission device

This transmission device includes a mode changeover switch (59) on which a mode changeover operation between a manual mode (M2) and an automated mode (M1) is externally performed, other operation unit (80) on which a predetermined shift operation is externally performed separately from the mode changeover switch (59), and a control unit (60) configured to control a mode changeover between the manual mode (M2) and the automated mode (M1). The control unit (60) executes the mode changeover between the manual mode (M2) and the automated mode (M1) on the basis of the mode changeover operation on the mode changeover switch (59). When the shift operation on the other operation unit (80) has been performed, the control unit (60) executes the mode changeover between the manual mode (M2) and the automated mode (M1).
