Abstract: A method for controlling a transmission of a vehicle includes: determining whether a controller receives an acceleration pedal off signal corresponding to a lift foot up (LFU) shift request signal from an acceleration pedal sensor; determining whether an output signal value of a brake pedal sensor detecting a position value of a brake pedal is less than a brake reference value when the acceleration pedal off signal is received; determining whether a gear shifting progressing rate of the transmission performing a LFU shift in response to the LFU shift request signal is less than a progressing rate reference value when an output signal value of the brake pedal sensor is equal to or greater than the brake reference value; and controlling the transmission to hold the LFU shift when the gear shifting progressing rate of the transmission is less than the progressing rate reference value.

Abstract: A vehicle is provided. The vehicle includes an engine, a motor, and a controller. The controller is programmed to inhibit a scheduled transmission downshift and increase a torque of the motor for a specified period of time in response to a torque demand being greater than a maximum torque capability of the engine but less than a maximum combined torque capability of the engine and motor. Upon expiration of the specified period of time, the controller may permit the downshift to occur. The specified period of time may be based on a state of charge of a battery at a time when the torque demand exceeds the maximum torque capability of the engine.

Abstract: Methods and systems are provided for performing a multiple gear downshift of a transmission gear by transiently operating in an intermediate gear. In response to ambient humidity and a condensate level in a charge air cooler, the transmission gear may be downshifted from a higher gear to an intermediate gear, and then to a requested lower gear. Downshifting through an intermediate gear may also be controlled based on the gear shift request.

Abstract: An automatic transmission capable of improving stability and reliability of connection operation of a synchronization mechanism when pre-shift control is executed, thereby making it possible to prolong the service life of the mechanism and improve marketability thereof. To change the speed position of a vehicle, one of two power transmission paths from an internal combustion engine to drive wheels is switched to the other, and pre-shift control is executed before switching the path. In doing this, when conditions for executing the pre-shift control are satisfied, whether or not a motive power fluctuation state of the engine occurs after satisfaction of the execution conditions is determined. If the motive power fluctuation state occurs, delay control for delaying the start of the pre-shift control is executed, whereas if the same does not occur, the pre-shift control is executed without executing the delay control.

Abstract: In the present invention, a decrease in the amount of regeneration is prevented, and discomfort is not imparted to the driving sensation of a driver. A determination unit determines whether or not a braking device is being operated by the driver. When decelerating while regenerating, a gear shifting control unit controls the shift of gears of a gear box in a manner so as to suspend the shift of gears and continue regeneration when it has been determined that the braking device is being operated by the driver. The present invention can be applied to vehicles that can regenerate electric power by means of an electric motor when decelerating and that are driven by the electric motor and an internal combustion engine via an automatic gear box.

Abstract: A bicycle gear shift control system capable of avoiding frequent gear shifting includes: a power module; a microcomputer electrically connected to the power module for allowing a cyclist to switch between the automatic gear shifting mode and a manual gear shifting mode; a gear shifting driver electrically connected to the microcomputer, substantially connected to a derailleur, and instructed by the microcomputer to drive the derailleur to perform gear shift control; and a manual shifting controller electrically connected to the microcomputer. The microcomputer has an automatic gear shifting logic whereby the microcomputer determines the timing of automatic gear shifting and performs gear shifting. The microcomputer further has a gear shifting delay logic that involves delaying for a delay time interval from commencement of gear shifting according to a gear shifting criterion and ruling out all other gear shifting commands during the delay time interval.
