摘要:
A sensor device has a quartz tuning fork and an analysis circuit arranged on a common board inside a common housing. The quartz tuning fork has its own, second housing within the common housing for acoustically decoupling the tuning fork from the analysis circuit. The second housing also has an opening for equalizing the pressure and temperature between the second housing and the rest of the common housing. The analysis circuit, which is connected via the electrical wires to the quartz tuning fork, performs linearization, signal amplification and elimination of environmental influences on the signals emitted by the quartz tuning fork. The signals processed by the analysis circuit are further transmitted via common housing's electrical contacts to external elements. Because of the physical proximity of the quartz tuning fork and the analysis circuit, interference attributable to electrical connections between the two elements is minimized. Furthermore, because the tuning fork and the analysis circuit are exposed to the same temperature, temperature-related fluctuations in the electrical signals of the tuning fork may be accurately counter-balanced by the analysis circuit.

The invention relates to a vehicle hydraulic brake system with electrohydraulic brake boosting by a piston pump. In order to reduce pressure pulsations on an intake side of the multi-piston pump, the brake system embodies a multi-piston pump, for example, as a six-piston pump with stepped pistons that are driven with an alternating phase shift of 30° and 90° in relation to one another. The phase shift of the drive of the stepped pistons is selected so that the intake volume flows have a uniform phase shift, by which the total intake volume flow of the multi-piston pump has a reduced amplitude of the pressure pulsation, which reduces the repercussions on a master cylinder.

A force sensor has a measuring diaphragm adapted to undergo a deflection in response to a force being applied thereto. The force sensor further has a test deflection device operatively coupled to the measuring diaphragm for effecting a test deflection thereof independently of any force external to the force sensor being applied to the measuring diaphragm.

摘要:
An image sensor and a method for manufacturing an image sensor are described in which the image sensor includes at least one substrate having a plurality of light-sensitive elements forming a sensor field and first microfilter elements for wavelength-selective filtering of incident light. The first microfilter elements are attached to a transparent carrier made of glass or a transparent film, for example. A first microfilter element is situated in front of a portion of the light-sensitive elements for wavelength-selective filtering of light striking the light-sensitive element. No microfilter element is situated in front of a further portion of the light-sensitive elements.

A device assembly for performing a driver assistance function includes a mobile terminal, and a holder removably installed in the vehicle for temporarily receiving the mobile terminal. At least one image recording device is connected to the holder and, to support the performance of the driver assistance function, is connectable to the mobile terminal via an image signal line and at least one first electrical interface situated in the holder when the holder receives the mobile terminal for performing the driver assistance function.
摘要:
A method and a device for controlling a vehicle, where an actuation variable of an operating control element operable by the driver is measured and converted into a controlled variable, using a predetermined correlation. In this case, the correlation can be changed by the driver, using a setting mechanism.
摘要:
The invention is directed to an arrangement for detecting the position of an accelerator pedal and/or a power-determining element of an internal combustion engine of a motor vehicle. The arrangement has at least two measuring devices as well as monitoring means which check the function of these measuring devices on the basis of the measuring signals thereof. In addition, a further measuring device in the form of a switch element is provided which likewise generates a signal representative of the position of an accelerator pedal and/or power-determining element of an internal combustion engine of a motor vehicle. A microcomputer selects on the basis of all three measuring signals at least one of the measuring signals for controlling the drive power of the engine in a motor vehicle. The switching element is a Hall switch.
