Abstract: Disclosed is a method for operating a multi-gear vehicle transmission having a plurality of shifting elements (A, B, C, D, E) for engaging gears of the vehicle transmission. In a neutral gear, in which some of the shifting elements (A, B) are already actuated, a transmission input (1) is decoupled from a transmission output (2) of the vehicle transmission. In a driving gear the transmission input (1) is coupled to the transmission output (2) of the vehicle transmission by closing the shifting elements (A, B, C, D, E) associated with the driving gear, in order to propel the vehicle. With the neutral gear engaged a transmission condition is determined, and if a transmission condition with elevated drag losses exists, then in addition to the shifting elements (A, B) actuated in the neutral gear a shifting element (D) associated with a reversing gear of the vehicle transmission is also closed.

Abstract: A method for controlling an automatic transmission of a vehicle includes: sensing a speed of the vehicle; sensing an acceleration of the vehicle along three spatial axes; determining that the vehicle is in a jump state associated with the vehicle being off a ground surface, the jump state being defined at least in part by the acceleration of the vehicle along the three spatial axes and the speed of the vehicle; and controlling the transmission according to a jump strategy in response to determining that the vehicle is in the jump state. Other methods for controlling an automatic transmission of a vehicle are also contemplated.

Abstract: A motorcycle includes a transmission, a first measuring unit, a second measuring unit, and a controller. The transmission is configured to automatically shift gears between a driving shaft and a driven shaft to transmit power from the driving shaft to the driven shaft. The first measuring unit is configured to measure the magnitude of a roll angle of a vehicle body. The second measuring unit is configured to measure the angular velocity of the roll angle of the vehicle body. The controller is configured to inhibit the transmission from shifting gears, based on the magnitude and the angular velocity of the roll angle. This configuration provides a motorcycle that enables gear shift control with more detailed response to a situation of a vehicle body.

Abstract: A method of controlling a transmission of a vehicle, includes determining, by a controller, whether a shift prohibition condition for preventing overheating of the transmission of the vehicle in a terrain mode, which is a rough road driving mode of the vehicle, is satisfied; determining, by the controller, whether a shift operation of the transmission corresponding to a busy shift phenomenon of the transmission is detected when the shift prohibition condition is satisfied; and prohibiting, by the controller, shifting of the transmission when the shift operation of the transmission corresponding to the busy shift phenomenon of the transmission is detected.

Abstract: A transmission control method has a normal stepless manner transmission mode and a pseudo-stepped downshift mode for controlling a continuously variable transmission connected to an input side of an engine. A downshift target rotational speed and a lower-limit target rotational speed used for the pseudo-stepped downshift are set to values in an engine rotational speed region in which an engine output becomes greater than or equal to a prescribed value. When a mode transition condition is satisfied during deceleration by selecting the normal transmission mode, the mode is shifted to the pseudo-stepped downshift mode to start the pseudo-stepped downshift. When the pseudo-stepped downshift is initiated, an increase to the downshift target rotational speed and a decrease to the lower-limit target rotational speed of the primary rotational speed are repeated, until the mode cancellation condition, including the re-acceleration request, is satisfied.

Abstract: A control apparatus for a vehicle automatic transmission includes a downshift determining unit that determines whether downshift of a gear shift stage is to be performed based on at least one of a history of lateral accelerations and a history of variations of a vehicle speed. A lateral acceleration history acquiring unit or a vehicle speed variation history acquiring unit returns at least one of the history of the lateral accelerations and the history of the variations of the vehicle speed to an initial value when a shift control mode determined by a shift control mode determining unit is switched. At least one of the initial value of the history of the lateral accelerations and the initial value of the history of the variations of the vehicle speed is a value that is set for each shift control mode determined by the shift control mode determining unit.

Abstract: At least one electric motor is employed for propelling an electric or hybrid vehicle with a shiftable transmission. Upon reaching a shift threshold, a shift operation is performed in the transmission of the vehicle, wherein a value specifying the shift threshold is varied depending on at least one parameter. As the at least one parameter, a speed is used, at which a power provided by the at least one electric motor for propelling the vehicle has a maximum.

Abstract: An apparatus of estimating a vehicle weight may include: an acceleration detector detecting a longitudinal direction acceleration of the vehicle; a data detector detecting state data to estimate the vehicle weight; an engine clutch disposed between an engine and a drive motor and selectively connecting the engine to the drive motor; an integrated starter-generator for starting the engine and generating electric energy; and a vehicle controller calculating a basic vehicle weight based on an engine torque, a motor torque and the longitudinal direction acceleration detected by the acceleration detector. The vehicle controller estimates a final vehicle weight based on the basic vehicle weight and a predetermined weight when an estimating entrance condition is satisfied from the state data.
