A wiper motor control circuit controls a drive circuit such that an actual speed of a wiper speed computed based on change in a rotation angle of an output shaft of the wiper motor detected by a rotation angle sensor that detects the rotation angle becomes a target speed corresponding to a position of a wiper blade indicated by the rotation angle detected by the rotation angle sensor. The wiper motor control circuit also controls the drive circuit so as to apply a braking current in the wiper motor when the actual speed has exceeded a threshold value when the rotation angle detected by the rotation angle sensor indicates a return position of the wiper blade.

A vehicular vision system includes a driver-side exterior mirror assembly, a passenger-side mirror assembly and an interior mirror assembly. The fields of view of the mirror reflective elements of the exterior mirror assemblies are adjustable by the driver via a respective actuator. The exterior mirror assemblies include respective cameras that each have a respective rearward field of view that supplements the field of view of the mirror reflective element when viewed by the driver of the vehicle. A video display is disposed behind the mirror reflector of an interior mirror reflective element such that displayed video images are viewable through the mirror reflector of the interior mirror reflective element. The video display includes a driver-side display portion and a passenger-side display portion that each display images derived from image data captured by the respective camera while not displaying images derived from image data captured by the other camera.

An external lens washing system has an aiming fixture configured to support and constrain an external lens which is exposed to the elements and apt to become soiled with debris. A nozzle assembly is configured to be supported and aimed toward the external lens by the aiming fixture and has at least one laterally offset washing nozzle projecting from the aiming fixture to a spray washing fluid toward the external lens surface, spraying at a shallow, glancing spray aiming angle to impinge upon and wash the lens external surface. Optionally, an integrated image sensor and lens washing assembly is configured for use with a remote control method for cleaning an exterior objective lens surface and includes a sealed image sensor housing assembly including an integral, remotely controllable lens cleaning system with an optimized configuration for aiming one or more cleansing sprays from one or more laterally offset fluidic oscillators.

A brushless direct current electric motor for a wiping system. The brushless direct current electric motor includes a rotor, a stator, a Hall effect sensor to detect control magnet angular position of the rotor, and a control unit to determine rotor angular positions in relation to the stator from the signals Hall effect sensor signals and to generate control signals to electromagnetic excitation coils of the rotor as a function of the determined angular position of the rotor. The control unit includes a clock configured to: estimate the angular position of the rotor at predetermined instants lying between two changes of state of the Hall effect sensor, determine values of the control voltages associated with the angular positions of the rotor estimated for the predetermined instants, and generate a substantially sinusoidal control signal from the determined voltage values.

A vehicle is disclosed that uses data from different types of on-board sensors to determine whether meteorological precipitation is failing near the vehicle. The vehicle may include an on-board camera capturing image data and an on-board accelerometer capturing accelerometer data. The image data may characterize an area in front of or behind the vehicle. The accelerometer data may characterize vibrations of a windshield of the vehicle. An artificial neural network may run on computer hardware carried on-board the vehicle. The artificial neural network may be trained to classify meteorological precipitation in an environment of the vehicle using the image data and the accelerometer data as inputs. The classifications of the artificial neural network may be used to control one or more functions of the vehicle such as windshield-wiper speed, traction-control settings, or the like.

A windshield wiper system for a vehicle. In one example, the windshield wiper system includes a drive, a wiper, and a control device, which is connectable to a continuous power supply of the vehicle. The control device is configured to communicate with at least one control unit of the vehicle via a predefined data transfer system, and to control the drive to move the wiper arm based on specifications from the control unit. Another example relates to a method for controlling a windshield wiper system of a vehicle, where the system is configured to clean a windshield of the vehicle by means of at least one wiper. The method includes monitoring an environment of the vehicle, establishing a wiper mode for detected conditions in the environment of the vehicle, and controlling a drive of the windshield wiper system to move the wiper according to the wiper mode.
