摘要： A current regulator for an inductive load especially for a coil of an electromagnetic solenoid valve. The current flow through the coil is regulated and compared by means of an operational amplifying nominal current value. The inductive load comparator is initially controlled by a first conductive diode. A second diode having a higher voltage rating than that of the first diode is rendered conductive whenever the nominal current value in an inductive coil decreases rapidly. The current regulator ensures that the magnetic energy in the inductive load remains unchanged when the nominal current value remains constant or changes in small amounts. When a rapid decrease of the coil current occurs, the second diode is rendered conductive.

摘要： An evaluation method for an inductive displacement sensor first temperature-compensates a measured sensor value, and then calibrates same. The temperature compensation is carried out iteratively, utilizing two temperature dependent functions. The first function is based on the temprature-dependency of the measured sensor value, and the second function is based on the dependency of the temperature coefficient of the sensor model used. For a clutch sensor application, a calibration line is defined by two calibration points, which represent a completely engaged state and a just disengaged state, respectively. Continuous measurement of the displacement of an engaged clutch indicates the wear status of the clutch, so that a warning can be transmitted to the driver when the clutch lining has reached a predetermined thickness.
摘要翻译：感应位移传感器的评估方法首先温度补偿测量的传感器值，然后进行校准。利用两个温度依赖函数，迭代地进行温度补偿。第一个功能是基于测量的传感器值的温度依赖性，第二个功能是基于所使用的传感器模型的温度系数的依赖性。对于离合器传感器应用，校准线由两个校准点定义，分别表示完全接合状态和刚刚分离的状态。接合离合器的位移的连续测量表示离合器的磨损状态，使得当离合器衬片达到预定厚度时可以向驾驶员传递警告。

摘要： For a valve arrangement of a pneumatically actuated, spring-loaded control cylinder, a non-return valve in pneumatic communication with the control cylinder piston chamber. At very low backpressures in the control cylinder piston chamber caused by leaks of the valve responsible for pressurization of the piston chamber, the chamber is vented by passage of a very small air stream via the non-return valve. In this way, leaks cannot cause a very slow pressure buildup in the control cylinder piston chamber, followed at some time by undesired shifting of the control cylinder. In contrast, in the case of normal pressure buildup, i.e., during switching of the pressurizing valve, the non-return valve is promptly closed and the pressure in the control cylinder piston chamber is not influenced.
