In a planetary gear arrangement with a planetary gear which includes a rotating part and a non-rotating part, and with a sensor module for sensing properties of the planetary gear, the sensor module includes a sensor as well as a first sending/receiving unit and a second sending/receiving unit, wherein the sensor and the first sending/receiving unit are coupled and arranged at the rotating part, and wherein the second sending/receiving unit is arranged at the non-rotating part, wherein the first sending/receiving unit and the second sending/receiving unit are configured for being inductively coupled, wherein the first sending/receiving unit includes an energy storage, wherein the energy storage is configured for being charged during each turn of the rotating part for powering the sensor via the first sending/receiving unit in order to perform measurements.

Planetary gear arrangement

A method for operating a drive-train () of a motor vehicle having an internal combustion engine, a transmission connected between the internal combustion engine and a drive output, and a brake assembly. While the motor vehicle is traveling, if a manual command is given or if defined operating conditions exist, the drive-train () is operated in a coasting mode, in which the drive-train () is disengaged and the internal combustion engine is turned off. If the internal combustion engine, turned off for the coasting mode, fails to restart despite the existence of a signal to restart the internal combustion engine, a braking process is initiated automatically.
