Method and Control Unit for Operating a Transmission of a Motor Vehicle
A method for operating a transmission (2) of a motor vehicle includes, in order to trigger a gear shift in the transmission (2), determining a trigger speed depending on a response time of the gear shift to be implemented, depending on a gradient of a motor vehicle-side rotational speed, and depending on a maximum permissible limit speed for the motor vehicle-side rotational speed. The gear shift to be implemented triggered on a control side as function of the trigger speed such that the motor vehicle-side rotational speed does not exceed the maximum permissible limit speed during the implementation of the gear shift. The method also include adapting the trigger speed.

Method and a device for controlling gear shifting in a vehicle with a transmission
The invention relates to a method and an arrangement for controlling a gearshift in a vehicle with a transmission (120) comprising a stepped gearing, the transmission (120) being arranged between an engine (110) and at least one driven axle (123), wherein the engine and the transmission are controlled by an electronic control unit (140), The method involves monitoring at least one parameter related to a vehicle operating condition; registering that a manual upshift command is requested; determining a desired shift point and a target engine speed based on a parameter comprising at least current engine speed; and performing an upshift when the target engine speed is reached.

Data Processing Device and Computer-Implemented Method for Synchronized Shifting of Bicycle Gearboxes, Bicycle Gearbox and Method of Operating the Same
A data processing device and a computer-implemented method for controlling a gear change in a bicycle gearbox for a bicycle with or without an auxiliary motor, in particular a bottom bracket gearshift device or a hub gear, from one gear directly into another gear by automatic actuation of a first and a second clutch actuator. A bicycle gearbox with such a data processing device as well as to a method of executing a gear change. The data processing device is configured to receive at least one switching parameter representative of a state of the bicycle gearbox, and to output an actuation signal for actuating the first and the second clutch actuator depending on the at least one switching parameter and a gear change signal representing a command for a gear change.
Control device for vehicle drive device
A control device that controls a vehicle drive device. A starting control section executes internal combustion engine starting control in which the internal combustion engine in a stationary state is started while causing the disconnecting engagement device to transition from a disengaged state to a direct engagement state. A timing decision section that decides, on the basis of a rotational speed of the internal combustion engine, a supply start timing to start supply of a hydraulic pressure to a specific engagement device, which is one of the plurality of shifting engagement devices and is caused to transition from a disengaged state to a direct engagement state in order to establish a target shift speed for the speed change mechanism after a change, in the case where the target shift speed is changed during execution of the internal combustion engine starting control.
