  • Method for detecting the rotary angle positions of rotating parts of a wiper motor, and wiper motor
    Patent number: 11962260
    Abstract: The invention relates to a method for detecting the rotary angle positions (?, ?) of rotating parts of a wiper motor, the wiper motor having a brushless electric motor as a first part which comprises a rotor rotating about a first axis of rotation and which drives a gear wheel as a second part which rotates about a second axis of rotation and which comprises a driven shaft, and the rotary angle positions (?, ?) of the two rotating parts being detected by means of two sensor devices each having a signal generating element and a sensor element for detecting a changing physical parameter of the signal generating element.

  • Time of flight detecting method for a phase shifted signal train including a sequence of waves inserted between a first group and a second group
    Patent number: 11867545
    Abstract: In an embodiment a method includes transmitting a signal train through a medium, wherein the signal train includes a sequence of waves of a first group and of a second group, the first and second groups being shifted in a time domain according to a predetermined phase shift, receiving the signal train as a received signal train and as a function of time, detecting a phase shift in the received signal train, assigning wave periods of the received signal train to respective wave periods of the first group using the detected phase shift as reference and determining a sequence of time-of-flight signals from the sequence of waves of the first group and the assigned wave periods of the received signal train, respectively.
