A method for operating a drive system including a drive engine for a motor vehicle, including carrying out an acceleration monitoring of the motor vehicle; switching to an alternative monitoring when a signal, which is relevant for the acceleration monitoring and for which a substitute signal exists, does not exist or has failed, and when a driver input which is below a predefined threshold value is specified, and/or a braking intent is specified.

Method and device for operating a drive system for a motor vehicle including an acceleration monitoring system

A method for operating a drive system having at least one drive engine for a motor vehicle, having the following: carrying out an acceleration monitoring of the motor vehicle, a changeover to an alternative monitoring being made when the acceleration monitoring can no longer carry out a reliable monitoring, and, in the alternative monitoring, an engine rotational speed being limited to a maximum permissible engine rotational speed; and ascertaining the maximum permissible rotational speed as a function of a rotational speed specification specified by a driver's request.

Method and device for operating a drive system for a motor vehicle

A method () for exiting a sailing mode of a vehicle () is described. The vehicle () comprises a clutch unit () which is disengaged in order to decouple a driving shaft () of the vehicle () from a driven shaft () of the vehicle (), when the vehicle () is operated in the sailing mode. The method () comprises predicting () that a trigger for an exit of the sailing mode will occur, and initiating () the preparation of the clutch unit () for engagement, subject to predicting that a trigger for the exit of the sailing mode will occur. Furthermore, the method () comprises detecting () a trigger for the exit of the sailing mode, and adapting () a shaft speed () of the driving shaft (), subject to detecting a trigger for the exit of the sailing mode. In addition, the method () comprises engaging () the clutch unit (), subject to preparing the clutch unit () for engagement and subject to adapting the shaft speed (), in order to exit the sailing mode.

Method and system for exiting a sailing mode of a vehicle

A method and arrangement is provided for controlling a motor vehicle drive train equipped with at least one drive motor, a torque converter, an automatic transmission and at least one electronic drive control device. In the drive control device, a function module is implemented for carrying out a creep control. This creep control can be activated independently of a brake actuation, when the actual rotational speed of the driving motor is greater than a defined desired rotational speed of the driving motor, and when the actual rotational speed of the driving motor cannot be reduced because of at least one defined condition as the minimally possible rotational speed of the driving motor.

Device and method for controlling a motor vehicle drive train

A method for adjusting the point of engagement of a friction clutch of a step-variable transmission for a motor vehicle, in particular a friction clutch of a dual clutch transmission. The friction clutch is controllably actuated by means of a clutch actuator and at least one synchronizer shifting clutch is controllably actuated by means of a shift actuator for the engagement and disengagement of a gear ratio of the spur-gear transmission. A set-point of the clutch actuator for the point of engagement of the friction clutch is adjusted as a function of a speed gradient value, which ensues from a transitional state with the friction clutch actuated and the shifting clutch actuated, once the shifting clutch is opened. The transitional state is established by setting the clutch actuator and the shift actuator to a respective transitional value substantially at the same time or, at least in sections, in parallel.

Method for kiss point adaptation

A method reduces the noise in the drive train of a motor vehicle having an automatic transmission or a manual transmission with a controllable oil pressure supply and/or automatic starting clutch. An engine sided drive unit is connected to the transmission input shaft by way of a spline connection, wherein noises in the drive train are caused by a clearance fit in the spline connection between the engine sided drive unit and the transmission input shaft. The transmission control is adapted for reducing the noise when in neutral.
