A sensor arrangement () for an automated transmission includes multiple axially parallel shift rails () being axially displaceable by associated shift actuators (). The sensor arrangement () has multiple displacement sensors () made up of a signal transmitter () attached to a shift rail and a signal receiver () fixedly arranged on a housing. The signal transmitters are in the form of a permanent magnet, and the signal receivers are in the form of a 3D Hall sensor. To detect an external magnetic interference field, which can corrupt the sensor signals from the displacement sensors (), the signal transmitters () have identical axial alignments of their magnetic poles, and the signal receivers () are in a common plane () that is horizontal in their installation position.

A compressor system for generating compressed air for a compressed air supply system in a vehicle. The compressor system includes a brushed direct current electric motor (BDC electric motor); a compressor configured to be driven by the BDC electric motor; and a control unit for controlling the BDC electric motor and allocated to the BDC electric motor so as to delimit an operating current of the electric motor. A free-running current path is allocated to the control unit, the free-running current path being configured to delimit the operating current of the electric motor in a variable manner. A switch controller is allocated to the control unit, the switch controller being configured to specify a switched-on time period (t_ON) and/or a switched-off time period (t_OFF) for the electric motor in a variable manner.

Compressor for generating compressed air, compressed air supply system, pneumatic system, and method for operating a compressor

A compressor for producing compressed air, in particular for a compressed air supply system of a vehicle, includes an electric motor in the form of a brushed direct current electric motor. The compressor has at least one first and one second compressor step, which can be driven by the electric motor. The motor can be controlled by means of an electronic control module of a control device by limiting an operational flow of the motor.

A measurement method for a mechatronics apparatus, which includes an electromagnetically actuated component, an electronic control circuit, and at least one sensor, is selectively timed to minimize electromagnetic interference between the electromagnetically actuated component and the sensor(s). This is accomplished by restricting a sensor measurement to a time window, during which time the electromagnetically actuated component either has no current flow, or has a current change magnitude that is lower than a predetermined limit.

A level control system controls the distance between the vehicle axles and the vehicle frame of a vehicle. The suspension is a full or partial air suspension, wherein the vehicle frame over the vehicle axles is supported via air suspension bellows. A vehicle inclination, i.e. a non-parallel alignment between vehicle frame and one or more of vehicle axles may occur as a result of various situations which may be dramatically different from one another. Uneven support of the vehicle represents one cause of vehicle inclination, for example, when one wheel of a vehicle axle is standing on the sidewalk. In order to avoid air losses, a vehicle level is not compensated for while the vehicle is stopped. Instead, the existing inclination is maintained and is entered into the control system as a target level. All level changes which occur due to changes in the load of the vehicle are compensated for by means of this prescribed target value. When the vehicle later starts to travel, the pressures in the air suspension bellows need to be modified only slightly, if at all, further conserving air consumption.
