摘要:
The invention relates to an optical sensor for motor vehicles, for detecting ambient parameters that affect vision, having at least one transmitter and at least one receiver for electromagnetic waves (light waves), in which a windshield is disposed in a measurement segment between the at least one transmitter and the at least one receiver and influences a wave propagation between the at least one transmitter and the at least one receiver in such a way that when a film develops on the windshield, and especially when wetting occurs from precipitation, an output signal generated by the receiver varies and serves to trigger a windshield wiper system. It is provided that at least one of the receivers (16, 20, 22) of the optical sensor (4) receives electromagnetic waves (light waves) of an ambient brightness of the motor vehicle and serves to trigger a light system of the motor vehicle.

An optoelectronic sensor 1 for detecting foreign bodies, especially raindrops on a windshield, includes an outer housing part 2 and an inner housing part as well as a fastening device 4, which is glued to a pane 5. A fastening means, for instance comprising two slides 6, is provided, guided in the outer housing part 2, and can be made to engage the fastening device 4 for securing the sensor 1 to the pane 5. In the interior of the sensor 1, the inner housing part, which carries the optoelectronic elements of the sensor 1, is pressed toward the pane 5 with a spring force braced against the outer housing part 2, in order to accomplish the optical coupling with the pane.

A plug-in module for an electric motor-driven window lift, in particular for use in a motor vehicle, is embodied so that it is economical to manufacture by having as few assembly steps as possible. The plug-in module is configured with a plug which has a plug housing made of plastic having partially injection-embedded plug contacts and motor contacts, a seal for sealing the plug against a drive housing of the window lift and a receptacle for at least one support element for electronic components being integrated. This support element makes electrical contact with the connector sections of the contact elements and the motor contacts upon insertion into the receptacle. The window lift is preferably used in automotive engineering.

A circuit arrangement, in particular for a wiper arrangement for motor vehicle windshields, having an electric wiper motor and a step-switching unit for the wiper motor that can be actuated via a control device, and wherein at least one output of the control device that is assigned to a specific wiper speed is connected to at least one input of the step-switching unit that determines this wiper speed. A switching means (18) is parallel-connected to the outputs (20, 24) of the control device (12), by way of which a voltage source (U.sub.bat) can be connected with the inputs (22, 26) of the step-switching unit (14), which are assigned to the outputs (20, 24) of the control device (12).
摘要:
A breather valve for a gas tank of an internal combustion engine having an adsorption filter which is linked to the atmosphere by a breather line which is controlled by a shut-off valve. As air flows through the shut off valve, contaminations entrained in the shut off valve may deposit in the shut-off valve, so that it will no longer close tightly. For this reason, a particle filter has been arranged in front of the shut-off valve. The particle filter is of a large surface area which is integrated in the housing of the adsorption filter, thus contamination of the shut-off valve (51) and an excessive pressure drop of the air flowing through the particle filter (41) is avoided. The integrated construction facilitates a simple assembly of the adsorption filter (41) which is suitable for internal combustion engines in motor vehicles.
摘要:
A device which determines a condition of at least one wiper blade of a motor-vehicle windshield wiper. The device includes a rain sensor controlling the motor-vehicle windshield wiper and being utilized for determining the condition of the wiper blade. The device also includes an evaluation circuit receiving data from the rain sensor. The evaluation circuit evaluates wear and tear of a rubber wiper element of the wiper blade based on one of a slow and continuous change of the data and a quick and continuous change of the data provided by the rain sensor.
