摘要:
The invention relates to a method for detecting surroundings by means of an automotive night vision system comprising several areas, including a detection area (3) in which surroundings-related data is detected, an evaluation area within which the surroundings-related data detected by means of the night vision system is evaluated, and an area of representation in which information about the surroundings-related data detected therein is represented to the driver by means of an optical display unit. All previous commercially available night vision systems are configured so as to be able to display objects at the greatest possible distance. However, said systems involve the great risk of leading the driver into driving faster than would be possible without the night vision system in situations where visibility is poor or in the dark. The area of representation is therefore restricted in the inventive method for detecting surroundings such that the area of representation comprises no more than the high beam area (2). The driver is shown only the surroundings-related data which he/she would see anyway when actuating the conventional high beam due to the fact that the area of representation is restricted.

Future motor vehicles will require additional lighting means. Additional lighting means are required, above all, in conjunction with environmental sensors, especially sensors which are used in night vision systems. As a result of the generally increasing number of electric and electronic systems in motor vehicles, such systems must be easy to operate for the driver. The invention thus relates to a switching arrangement which enables a plurality of lighting systems to be ergonomically operated on one motor vehicle. Said switching arrangement comprises a single switch having a plurality of switching stages. In this way, all switching stages pertaining to different lighting systems are located in the same switching region, enabling the lighting systems to be operated in a simple and intuitive manner.

Vacuum cleaner for use in industry and household comprising a housing and an electric motor driving the blower generating the working vacuum, and optional maneuvering means for moving a suction nozzle over the material to be cleaned. There is provided in the area of the channel passed by the dust and dirt particles drawn in, an optical sensor comprising a light transmitter and a coacting light receiver so that the quantity of the dust and dirt particles drawn in at any time is detected. After comparison of the value so determined with a given threshold value, either a visual and/or an acoustic signal are obtained and/or a power variation of the electric motor driving the blower is effected.

First commercial automobile night vision systems are already available on the market. These should assist the driver in difficult situations involving poor visibility, particularly in darkness or fog. To this end, systems of this type have an active infrared illuminating device (2), a camera (3) for recording infrared images, and an image display (1) for playing back the image information obtained by the system. In doing this, the activation of the active infrared illuminating device (2) ensues according to an evaluation of operating parameters (5) and parameters (6) of the surroundings (4). In addition, according to a feature of the present invention, a controller (7), which is independent of the evaluator (4), is provided for directly activating/deactivating the image display (1). The controller (7) enables the driver to immediately obtain information regarding a successful activation of the night vision system.

In a vehicle headlight system with a light source (2) and at least one reflector (1) for shaping the light emitted by the light source into a high beam and a low beam, and with a shield (7) adjustable via an actuating element (9) between a position in which the light from the light source (2) is blocked across a maximum cross section and an essentially transmissive position in which this light is substantially allowed to pass through, the actuating element (9) adapted for adjusting the shield (7) in a plurality of intermediate positions between the maximal blocking and the essentially transmissive position in which intermediate position the blocked cross section is less than the maximal cross section.
摘要:
Environment detection systems are used to aid drivers in road vehicles. To this end, optical sensors are applied to the road vehicle in order to record environmental data. The recorded environmental data is processed to form an image by means of a computing unit, and is then presented to the driver, for example on a display. In addition, the image data can be subjected to a further evaluation, for example, in order to identify objects located therein. For this purpose, a very large amount of data must be processed however, such that the requirements for the efficiency of the hardware are very high, in order to provide the system with a real-time capacity. The invention thus relates to a method which provides the system with a real-time capacity by means of simple data processing. By carrying out a multi-stage evaluation in individual identification partial regions and by limiting the identification region to the region of the driving lane, the quantity of data to be evaluated can be considerably reduced and the data can be rapidly processed during the environment detection process.

In a brake shoe (1), particularly for a disk brake of motor vehicles, comprising a carrier plate (2) on which a friction lining (6) is fastened, in which outwardly open grooves (8) are arranged in a groove pattern, it is provided that for the reduction of moment vibrations during the braking procedure, the grooves (8) are filled up with an elastic filler (12) that does not consist of abrasive material.
摘要:
A method and arrangement for controlling the output of electrical consumers connected to ac line voltage, especially of electric motors and the like, in which the output is changed by changing the phase control of the electric alternating magnitude supplied to the consumer. The extent of the firing angle determining the extent of the phase control is varied toward larger or smaller values around the given reference value of the firing angle, which reference value corresponds to the desired power consumption, so that asymmetry of the firing angle is produced with respect to time between two successive full waves, whereby odd-numbered harmonics are sharply reduced as even-numbered harmonics slowly increase.
