The invention relates to a device (3) for protecting an optical sensor (13) for a motor vehicle. According to the invention, the protection device (3) comprises: a housing (4) which is mounted in such a way that it rotates about a rotational axis (A1) and has a receiving element (19) designed to receive the optical sensor (13) such that the optical axis (15) of the optical sensor (13) merges with the rotational axis (A1), a transparent optical element (9) constrained to rotate with the housing (4) and designed to be arranged in front of the housing (4) facing the road and such that it is centred in relation to the optical sensor (13), and an actuator (5) for rotating the housing (4), so as to clean said optical element (9) by means of a centrifugal effect. The invention also relates to a driving assistance system (1) corresponding in this way to a cleaning method implementing such a protection device (3).

A replay plate 44 is set to have a vertically and horizontally symmetrical shape when a worm wheel 33 is viewed from its axial direction; the worm wheel 33 is provided with an accommodating concave portion 33g in which the relay plate 44 is housed so as to be recessed in the axial direction; and a part of a non-slidably contacting surface in a slidably contacting surface 44a of the relay plate 44, i.e., a non-slidably contacting surface S is covered with first and second fixing parts 35a, 35b that are provided around the accommodating concave portion 33g and protrude in a direction intersecting with an axial direction of the worm wheel 33, the non-slidably contacting surface being a surface with which the contact plate is not slidably contacted.

An extendable windshield wiper system includes a wiper blade assembly having: a resilient material wiper blade; and a wiper extension rod connected to the wiper blade. A wiper sleeve is configured to move about an arc of rotation with respect to an axis of rotation of the wiper sleeve. A bore of the wiper sleeve has the wiper extension rod slidably disposed within the bore. An actuation portion directs a pressurized fluid to outwardly extend the wiper extension rod from the wiper sleeve and thereby to outwardly extend the wiper blade in an extension direction during a first portion of the arc of rotation. The wiper blade is induced to traverse an extended arc of travel during rotation of the wiper extension rod and the wiper sleeve along the arc of rotation.

A wiper driving apparatus according to embodiments comprises: a sensor unit including a carbon micro coil; a precipitation amount sensing unit for outputting an output value corresponding to the value of a difference between a first frequency and a preset second frequency according to a change in the impedance value of the sensor unit; and a control unit for determining whether there is precipitation and the amount of precipitation by using the output value output through the precipitation amount sensing unit, and determining wiper driving conditions according to the determined results, wherein the first frequency is changed to correspond to a change in the inductance value of the carbon micro coil according to whether there is precipitation and the amount of precipitation.

Systems and methods for cleaning, drying, and thermally managing vehicle components are described herein. In some embodiments, the vehicle components can include various sensors and, more particularly, the surfaces of cameras, LIDAR sensors, etc., that need to be clean to effectively perceive the environment around the vehicle. In one embodiment, a cleaning system includes a central delivery system configured to route fluid, such as washer fluid, along one or more delivery channels to remote holding chambers. The holding chambers can hold and/or heat the fluid before delivering the fluid to nozzles that spray the fluid on nearby vehicle components to clean the components.

A pedestrian protecting device according to one aspect of the present invention includes: a right air bag device including a right air bag configured to be deployed at a right region of the windshield; and a left air bag device including a left air bag configured to be deployed at a left region of the windshield. A wiper device includes a right wiper and a left wiper including a turning fulcrum located closer to a middle portion of a vehicle than a turning fulcrum of the right wiper. The right and left air bags and include respective tip end portions that vertically overlap each other at the middle portion of the vehicle. The right air bag of the air bag device is deployed before the left air bag of the air bag device is deployed.
