    摘要: The invention relates to a method for operating a rotating electric machine (1) having a rotor (3), a polyphase excitation winding (5) and a commutation apparatus (9) for commutating excitation winding currents of the excitation winding (5) depending on rotor position values (R) for rotor positions of the rotor (3). First measurement values (A) for the rotor positions are detected by means of a first sensor apparatus (13) and second measurement values (B) for the rotor positions are detected by means of a second sensor apparatus (15). For the commutation of the excitation winding currents, the rotor position values (R) are formed from weighted mean values (M) of the first measurement values (A) and the second measurement values (B). In a first rotation speed range of rotor rotation speeds of the rotor (3), the first sensor apparatus (13) has a higher resolution of the rotor positions than the second sensor apparatus (15) and, in the first rotation speed range, the first measurement values (A) are given more weight than the second measurement values (B) when forming the weighted mean values (M).

    摘要: The invention relates to a pneumatic solenoid valve comprising an air chamber (1), on which multiple air connections (2, 3, 5) are provided which can be connected via multiple switching positions of the solenoid valve by interconnecting the air chamber (1). The solenoid valve comprises a magnetic coil (6), a yoke (8) which is arranged on the magnetic coil (6) and made of soft magnetic material, and an armature (9) which can move relative to the yoke (8) and is made of soft magnetic material. The magnetic coil (6), the yoke (8) and the armature (9) are arranged within the air chamber (1). The armature (9) is arranged with respect to the yoke (8) such that, when the magnetic coil (6) is fed with current, said armature rotates about a single axis of rotation (A), by means of the magnetic force generated as a result, against a restoring force until the magnetic force corresponds to the restoring force. When the armature (9) rotates, the size of at least one overlapping region between the yoke (8) and the armature (9) changes, wherein an air gap (L, L′) is formed between the yoke (8) and the armature (9) in the at least one overlapping region. The distance formed by the air gap (L, L′) between the yoke (8) and the armature (9) remains substantially constant in the direction of rotation of the armature (9).

    摘要: A sensor dome arrangement has a sensor dome and a housing wall, which is particularly a transmission wall. The sensor dome includes a sensor, dome contacts which are electrically connected to the sensor, and a dome housing. The dome housing has a first dome housing section in which the sensor is arranged, and a second dome housing section on or in which the dome contacts are arranged. A through-opening is made in the housing wall, and the sensor dome is attached to the housing wall such that at least one outer surface of the first dome housing section faces a first chamber which is adjacent to the sensor dome and an inner side of the housing wall, and such that the dome contacts face a second chamber which is adjacent to the sensor dome and an outer side of the housing wall.

    摘要: In a method and a device for safely parking a vehicle, an actual distance of the vehicle from a road edge fixture is monitored relative to a specified minimum distance value during a manual or automatic parking maneuver, and upon completion of the parking maneuver, at least two wheels of the vehicle are automatically controlled to turn toward the road edge fixture in the direction of travel dependent on the actual distance relative to the specified minimum distance value.
