BRUSHLESS WIPER MOTOR
Since a shape of a stator 44 is made mirror symmetric with respect to a rotor 45 as a 4-pole/6-slot type, rotational deflection of the rotor 45 can be suppressed. As the minimum number of poles and the minimum number of slots, which can suppress the rotational deflection of the rotor 45, a frequency of magnetic noises approaches a frequency of mechanical noises. Thus, it is possible to integrate the whole noises generated by the DR-side wiper motor 21 into a low frequency range thereof, and to make the acoustic sensitivity (dB) of a vehicle interior smaller. Since the stator 44 is fixed inside a housing 40 and mounting legs fixed to a vehicle body fixed portion are provided in the housing 40, the stator 40, which is a source of the magnetic noises, can be fixed to a vehicle via only the housing 40. Therefore, a brushless wiper motor with quietness improved further can be designed.
SYSTEMS AND METHODS FOR DETECTING OBSTRUCTIONS IN A CAMERA FIELD OF VIEW
A system mounted on a vehicle for detecting an obstruction on a surface of a window of the vehicle, a primary camera is mounted inside the vehicle behind the window. The primary camera is configured to acquire images of the environment through the window. A secondary camera is focused on an external surface of the window, and operates to image the obstruction. A portion of the window, i.e. window region is subtended respectively by the field of view of the primary camera and the field of view of the secondary camera. A processor processes respective sequences of image data from both the primary camera and the secondary camera.

Temperature sensor device for a windshield of a vehicle
A temperature sensor device for sensing a temperature of a windshield of a vehicle includes a single printed circuit board having a circuitry, a temperature sensor mounted on the printed circuit board, and a thermally conductive pad attached to the temperature sensor. The thermally conductive pad is arranged to thermally and mechanically directly contact the windshield.
WEATHER-DEPENDENT DRIVER ASSISTANCE SYSTEM
A control system (200) for a vehicle (1), the control system comprising one or more controllers (201), wherein the control system is configured to: receive (402) information indicative of a weather condition; and in dependence on the information indicative of a weather condition, modify (406) at least one spatial range parameter of a driver assistance system configured to monitor other road users.
Automotive rain detector using psycho-acoustic metrics
An automatic wiper control system for a vehicle window determines the presence of rainfall based on window vibrations. During a vehicle driving cycle, a controller measures the window vibrations with an accelerometer attached to the window. The controller calculates a psycho-acoustic metric based on the measured vibrations, wherein the metric can be comprised of Articulation Index, Sharpness, or Roughness. The calculated metric is compared to a threshold indicative of rain impacting the window. The wiper system is activated according to a result of the comparison.
Vision system for a vehicle
A vision system for a vehicle includes a driver-side exterior mirror assembly having a driver-side camera for capturing driver-side image data and a passenger-side exterior mirror assembly having a passenger-side camera for capturing passenger-side image data. A video display disposed at the vehicle displays video images derived from image data captured by the driver-side and passenger-side cameras. The video display includes a driver-side display portion and a passenger-side display portion. The driver-side display portion of the video display displays video images derived from driver-side image data captured by the driver-side camera and does not display video images derived from any passenger-side image data captured by the passenger-side camera. The passenger-side display portion of the video display displays video images derived from passenger-side image data captured by the passenger-side camera and does not display video images derived from any driver-side image data captured by the driver-side camera.
Detection and identification of opaqueness of vehicle windows
Method and apparatus are disclosed for detection and identification of opaqueness of vehicle windows. An example vehicle includes a window including an interior surface and an exterior surface, a light transmitter to emit light, and light sensors to measure the light.
