To provide a technique of eliminating condensation adhering to a vehicle inner side of the glass to improve the reliability of a vehicle-mounted optical device. A vehicle-mounted optical device includes: an imaging unit that captures an outside of a vehicle through glass mounted to the vehicle to obtain an image; a condensation detection unit that detects condensation of the glass by determining whether an image in a predetermined range of a part of the image is in a predetermined state; and a condensation removal device control processing unit that actuates a condensation removal device which removes condensation of the glass when the condensation detection unit detects the condensation.

An optical rain sensor device includes a first light emitting element adapted to emit a first light pulse toward an inner surface of a transparent substrate, a second light emitting element adapted to emit a second light pulse toward the inner surface of the transparent substrate, a photodetector adapted to detect a light from the first light pulse and the second light pulse that is reflected by the inner surface of the transparent substrate, and a rain sensor controller. The rain sensor controller includes a regulated current source adapted to apply a compensation current signal at a terminal of the second light emitting element based on a regulation signal, so that a total current across the second light emitting element is increased or decreased to reduce an imbalance between the first light pulse and the second light pulse.

A gear side feeding terminal (73U, 73V, 73W) connected to a motor side feeding terminal (36U, 36V, 36W) provided to the end portion of a stator (32) in the axial direction of the stator (32) from the axial direction of a rotor (38) is provided on a control board (70) for controlling the rotor (38), housed in a gear case (61) so as to be stacked on a speed reduction mechanism (SD) from the direction crossing the axial direction of the rotor (38). In this manner, the wiper motor is composed of a brushless wiper motor (20), and it is unnecessary to provide the gear side feeding terminal (73U, 73V, 73W) so as to avoid the control board (70). Accordingly, it is possible to prevent electric noises, and provide a wiper motor reduced in size and weight, and since it is unnecessary to form a clearance in the control board (70), it is possible to provide a wiper motor further improved in degree of freedom for designing the control board (70).

This disclosure relates to techniques for implementing a windshield wiper system with an actively movable platform. The windshield wiper system can include a windshield wiper arm mechanically coupled to a platform and an actuator mechanically coupled to the platform. The windshield wiper arm can be configured to move through a planar range of motion that is substantially parallel to a surface of a vehicle when the platform is positioned at a first spatial location and the movable windshield wiper arm can be configured constrained from moving through the planar range when the platform is positioned at a second spatial location.

Disclosed embodiments relate to a windscreen wiper drive of a windscreen wiper device of a rail vehicle. The drive includes at least one electric motor, a gear, the input shaft of which being connected to an output shaft of the electric motor, wherein an output shaft of the gear is provided for driving at least one windscreen wiper arm of a windscreen wiper, which arm swings back and forth with the output shaft, a rotation angle sensor unit, which detects a rotation of at least one element of the windscreen wiper drive, and a mechanical rotation angle limitation, which mechanically limits a rotational movement of at least one element of the windscreen wiper drive. The electric motor is formed by a disc motor and the gear is formed by a planetary gear.

A wiper system for vehicles is provided. The system includes a heated wiper blade assembly, a heated cowl assembly and a controller. The controller receives input from one or more sensors or systems and causes a power source to provide, reduce or stop power to heating elements in the blade and/or cowl depending upon sensed conditions. At least some components in the assembly comprise thermally conductive polymers. The system provides surprisingly advantageous results in that it is effective for melting and clearing ice and snow with a lower than expected pull on a power source such as a battery.

A windshield-wiper system includes a precipitation-detector, a windshield-wiper actuator, an object-detector, and a controller. The precipitation-detector detects precipitation proximate to a host-vehicle. The windshield-wiper actuator clears the precipitation from a windshield of the host-vehicle. The object-detector detects a distance of an object to the host-vehicle. The controller is in communication with the precipitation-detector, the windshield-wiper actuator, and the object-detector. The controller determines when the precipitation is present based on the precipitation-detector, determines the distance from the object to the host-vehicle based on the object-detector, and adjusts a speed of the windshield-wiper actuator when the precipitation is detected and the object is less than a distance-threshold away from the host-vehicle.

An occluded area on a vehicle sensor is identified by localizing the vehicle in space. A discrepancy between historic image data and real-time image data from the sensor is determined, and a cleaning actuator is actuated based on the determined discrepancy.
