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.

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.

A shift device according to one embodiment includes a case having a cylindrical portion; a shift lever configured to include a base portion provided to be rotatable inside the cylindrical portion, with which an operator performs a rotation operation; a shift position holding mechanism configured to hold the shift lever at a predetermined shift position; and an elastic member configured to protrude from one of the cylindrical portion or the base portion so as to face another of the cylindrical portion or the base portion, and contact either an outer circumferential surface of the base portion or an inner circumferential surface of the cylindrical portion, to impose a rotational load on the shift lever.

A selector assembly includes a housing having a spherical cavity and a detent cavity that form a continuous selector cavity. A selector slidably operates within the selector cavity and about a center point of the spherical cavity. The selector includes a spheroid member that is contained within the spherical cavity and slidably engages a guide surface that defines the spherical cavity. A first pivot includes a first rotational axis that extends through the center point of the spherical cavity. A second pivot includes a second rotational axis that extends through the center point of the spherical cavity. A detent pin is biased toward a detent surface of the detent cavity and slidably engages the detent surface to define a plurality of selector positions of the selector.

A control device wearable by a bicycle rider, the control device including at least one control sensor generating input signals when actuated. A control processor is connected to the at least one control sensor generating control signals responsive to the input signals. A wireless transmitter is in communication with the processor transmitting the control signals and a power source is connected to the shift control processor and the wireless transmitter. The control device may one or more of a control gear changer, one or more suspension component, and other electronically-controllable components or systems.

Described herein relates to a system of and method for recovering energy and providing power in a multi-source transmission assembly, in which the transmission assembly includes secondary power sources in combination with a primary power source, where the secondary power sources are in reverse rotation with respect to the primary power source, such that energy is recovered during deceleration or the secondary power sources power the vehicle as needed. During the translation of a vehicle employing the transmission assembly, at least one motor may function, as needed, to propel the vehicle forward. During times in which the vehicle may not positively accelerating, at least one of the motors may switch to a generator mode to generate energy to be stored in a vehicle battery. As such, at least one of the motor power sources may recover an amount of energy expended by the vehicle during acceleration.

There is provided a shift device for a straddle-type vehicle that is configured to cause a transmission device to perform a shift change in accordance with rotation of a shift shaft. The shift device includes: a shift lever provided with an operation portion that is configured to receive a shift operation; a shift sensor provided on the shift shaft so as to be integrally rotatable with the shift shaft; and a shift rod that couples the shift lever and the shift sensor. The shift sensor is configured to detect the shift operation on the shift lever in accordance with a movement of the shift rod. The operation portion and the shift sensor are positioned at the same side in a manner of sandwiching the shift rod.
