摘要： The present disclosure relates to a fog detection method in a vehicle comprising the steps of: providing a first fog sensor with a first transmitter emitting a first encoded optical signal into a vehicle's surroundings, and an associated first receiver for receiving an optical signal reflected from the vehicle's surroundings, and a first analyzing unit for decoding, analyzing and providing a first detection result related to the reception, wherein, for encoding, a code is selected among a plurality of possible codes (A,B,C) by the first transmitter in a code selection, and the code selection is communicated from the first transmitter to the first receiver and/or the analyzing unit, wherein, upon analyzing the signal received from the first receiver by the first analyzing unit, the code selection is used for identifying the first encoded optical signal in the received signal.

摘要： An input device includes a capacitive detection device, which has a detection surface while forming a first array of array electrodes associated with the detection surface, that are arranged so as to cross one another several times while being electrically insulated to form one junction point at the locations where they cross one another; an electronic evaluation unit, which is electrically connected to the array electrodes to form an associated electric measuring field array for the spatially resolving detection of a capacitive influence on the detection surface; a handling means mounted on the detection surface movable along an adjustment path parallel to the detection surface to perform an operating input by a manually effected movement along the adjustment path; and at least one position indicator moved along with the handling means to capacitively influence at least one measuring field of the measuring field array.

摘要： The invention relates to an input device comprising: a touch-sensitive input surface facing towards an operator (B); a detection device for the spatially resolved detection of an approach towards and touch on the touch-sensitive input surface having a sensor array for capacitive and/or inductive detection, which extends parallel to the input surface; an input part, which is disposed on the input surface and mounted so as to be movable from a rest position (X0) into an actuation position (XE) along an actuating direction (B1) extending perpendicularly to the input surface, for enabling a performance of an operating input by the operator (B) through a manual displacement of the input part along the actuating direction (B1); a position indicator for contactless position detection, which is attached to the input part and cooperates with the detection device; restoring means for generating a restoring force (F) with snap haptics counteracting the manual shifting from the rest position (X0); wherein the detection device is designed for acquiring a course over time of an approach towards the touch-sensitive input surface by means of a course over time of a sensor signal (Z(t)) of the detection device and to analyze the course over time of the sensor signal (Z(t)) and/or an associated frequency spectrum, and is further designed to assign a switching or controlling function exclusively if it was found in the preceding analysis that the course over time of the sensor signal (Z(t)) and/or the associated frequency spectrum has characteristics that are predefined by the snap haptics.

摘要： An input device is disclosed, including a capacitive force sensor, a capacitive touch sensor, and an evaluation unit, where the capacitive force sensor includes an operating surface and a first conductive electrode, and a second conductive electrode; wherein the evaluation unit is configured to detect an associated characteristic value of a touch on the operating surface during the operation, such as a location surface of action of the touch, by means of the capacitive touch sensor, and wherein the evaluation unit is further configured to detect a measured quantity changing with the operating force by generating a first measuring capacitance between the first and second electrodes and to assign a switching or controlling function to the operation in accordance with the characteristic value detected by the capacitive touch sensor and with the measured quantity detected in the operation-detection step.
