A wiper control device for controlling an operation of a wiper device is provided. The wiper control device includes an arm operation determination portion sets a stop position for stopping a wiper arm for a predetermined time above a lower reversal position, and when moving the wiper arm stopped on an upper reversal position side with respect to the stop position to a storage position set below the lower reversal position, temporarily stops the wiper arm at the stop position for a predetermined time, and moves the wiper arm to the storage position after the predetermined time elapses. The stop position is an arm falling position at which the wiper arm in a locked back state falls without contacting an engine hood of a vehicle, and a wiper blade contacts a windshield.

A method for controlling a cleaning assembly of an exterior sensor module for a roof of a vehicle. The method including receiving a contamination signal; assessing whether a trigger threshold is triggered for initiating a cleaning cycle, and on triggering of the trigger threshold, initiating a cleaning cycle comprising at least one cleaning action by providing an activation signal to a cleaning assembly. Herein assessing the trigger threshold includes at least one of assessing a position of the contamination on the visor for satisfying a relevance condition, assessing size of the contamination for satisfying a surface condition; and/or assessing a vehicle speed for satisfying a speed condition. An exterior sensor module and a roof equipped with such a sensor are further provided.

A method includes receiving an audio signal from a microphone and processing the audio signal to identify a signal component that is associated with a resonance of at least part of a microphone unit disposed on a vehicle. The microphone unit includes the microphone and a protective element arranged to shield the microphone from environmental material. The method includes determining, based at least in part on the identified signal components, a characteristic indicative of the protective element having shielded the microphone from environmental material.

An information processing device includes a communication unit and a control unit. The communication unit is capable of communicating with a plurality of vehicles. The control unit calculates the switching timing of the hand signal based on the traffic amount in the vicinity of the intersection, identifies the head vehicle stopped at the intersection, and controls the in-vehicle device capable of recognizing the operation from the outside of the head vehicle provided in the head vehicle via the communication unit based on the switching timing.

A motor control device includes a driving control part and an upper limit value setting part. The driving control part controls motor driving by switching between a first driving mode and a second driving mode, and controls an output duty ratio so as not to exceed a duty ratio upper limit value. The upper limit value setting part sets, as the duty ratio upper limit value, a low rotation duty ratio upper limit value, a maximum duty ratio upper limit value corresponding to a maximum output value, and an upper limit value of a transition period from the low rotation duty ratio upper limit value to the maximum duty ratio upper limit value, and changes slope information indicating a change amount in the upper limit value of the transition period according to the driving mode when switching between the first driving mode and the second driving mode.

A method for detecting liquid on a windowpane in which radiation is emitted by at least one radiation emitter, the radiation is coupled into the windowpane via at least one optical element, and, after reflection in the windowpane, the radiation is coupled out of the windowpane. The radiation which is coupled out of the windowpane is captured in single measurements. A measurement cycle is formed from a multiplicity of single measurements. An average value is calculated from the measurement results of a measurement cycle. The average value is used a reference value for the single measurements of the subsequent measurement cycle currently in progress. The differences between the measured values of the single measurements of a measurement cycle currently in progress and the reference value are determined. The differences between the measured values of the single measurements of the measurement cycle currently in progress and the reference value are evaluated statistically. A conclusion is drawn regarding the state of coverage with liquid of the measuring section on the windowpane from the statistical evaluation.

A windshield wiper control method of a new energy automobile includes the following steps: when a windshield wiper controller is in a first wiping state, if the windshield wiper controller receives a high-speed gear signal sent by a windshield wiper control terminal or receives a rainstorm instruction sent by a central control display screen, the windshield wiper controller entering a rainstorm mode; when the windshield wiper controller is in a second wiping state, if the windshield wiper controller receives a rainstorm instruction sent by the central control display screen, the windshield wiper controller entering a rainstorm mode; wherein the rainstorm mode is used for indicating the windshield wiper controller to control the windshield wiper windshield wiper, the key area of the automobile windshield is wiped at the safety frequency.

A windshield wiper blade assembly has a windshield wiper blade with an articulation element for articulating the blade to a wiper arm. An electrical connector includes two coaxial parts configured to rotate relative to each other, one part of which being intended to be secured to the articulation element and the other part of which being intended to be secured to the wiper arm. One part of the two coaxial parts is a male part including at least one male connector and the other part is a female part including at least one female connector associated with the at least one male connector, The least one female connector is arranged in a circular groove, so that said at least one male connector is able to move in rotation inside the groove and to contact the at least one female connector during the rotation of the two coaxial parts relative to each other.
