At least one of the chambers can be operated as a low-pressure chamber and at least another one of the chambers can be oerated as a working chamber. The device further includes a master braking cylinder in which a master cylinder pressure is generated over the pneumatic brake booster, and a hydraulic unit, which is installed between the master cylinder and at least one wheel brake cylinder of at least one wheel. The hydraulic unit includes an arrangement of switchable valves as well as least one pump. A hydraulic boost of the brake pressure is achievable with the assistance of the hydraulic unit.

Abstract: A piston pump for a hydraulic brake system of a vehicle with slip control. The piston pump has a piston which is received in a bush that is inserted into a cylinder bore of a pump housing that is closed in pressure-tight fashion by a closure part. For simpler assembly, the closure part is connected to the bush by means of a snap or detent connection. As a result, a preassembled unit that can be manipulated easily before insertion into the pump housing is obtained in a simple way.

The oscillating structure and/or the analyzing arrangement are connected to the substrate by mechanical decoupling devices.

Abstract: A method and an apparatus for operating a control unit for controlling operational sequences in a vehicle. When operational sequences are error-free, the control functions of the built-in control unit are partially or completely suppressed. This allows additional functions to be switched in and out, and also allows modification and/or adaptation of data and/or programs that are accessed by the control functions. In the specific operating instance of the application, a further control unit is insertable into the vehicle wiring harness between the first control unit and a sensor arrangement, collection, group or system and an actuator arrangement, collection, group or system. The control functions suppressed in the control unit are then performable by the second control unit. The control unit then performs only the measurement functions and actuation functions The sequence is initiated and controlled by integrated remote-control functions, which are in addition to the normal or other functions.

Abstract: A method for fabricating a locally reinforced metallic microfeature on a substrate provided preferably with an electrical contacting or a driving circuit, and on an organic, patterned sacrificial layer, which is removed after the metallic microfeature is applied, is described. In fabricating the local reinforcement of the microfeature, at least one further organic layer, formed as a mask, is deposited, which is likewise removed following pattern delineation of the metallic layer.

Abstract: A method via which the range of vision in a vehicle's field of view can be determined precisely, so that with the help of range-of-vision information the driver can be advised to modify his driving style. The contrast of an object detected by a radar or lidar sensor is measured by a monocular video sensor, and the range of vision is determined from the measured values supplied by the radar or lidar sensor and by the monocular video sensor. Alternatively, the distance to and contrast of at least one object can be measured by a binocular video sensor, the range of vision then being determined from the measured contrast and distance values.

Abstract: An apparatus for kinesthetic signaling to a driver of a motor vehicle is described. The apparatus signaling the driver if, in the context of a system for controlling vehicle speed, a deliberate shutdown or one occasioned by a malfunction is imminent or exists; or if, in the context of a system for controlling vehicle speed, a preset maximum deceleration value is not sufficient to prevent a collision between the motor vehicle and a preceding vehicle or an obstacle. The apparatus includes a device that modulates a braking setpoint, or a variable derived from it, in such a way that the motor vehicle experiences a temporally fluctuating deceleration that is perceptible by the driver.

Abstract: An electronically commutated motor includes a stator carrying a plurality of winding strands and a rotor in which the individual winding strands are controlled via power amplifiers in staggered periods of time, the periods being subdivided into control time and idle time. To reduce the power loss in the power amplifiers and to increase the efficiency in the range of high currents, that the control times are subdivided into an initial time segment and a final time segment. At low motor currents pulsing occurs only in the initial or final time segments in pulse width modulation, while at high currents complete switching through takes place in the initial time segments and additionally in the final time segment for a more or less long period of time or in the final time segments and additionally in the initial time segments for a more or less long period of time.

Abstract: A drum-in-hat park brake assembly having a first brake shoe retained on a backing plate by a first pin and a second brake shoe retained by a second pin. The first and second pins permit the first and second brake shoes to be moved in a radial plane and to rotate about an axis of an opening in the backing plate. The first and second brake shoes each have a first engagement end which is aligned on the backing plate by an anchor post and a second engagement end which is selectively spaced apart by an adjuster mechanism. A spring arrangement urges the first and second brake shoes toward the anchor post and into engagement with the adjuster mechanism. An actuator assembly is connected to the first engagement end of the first and second brake shoes and upon receiving an input force moves first and second friction pads associated with the first and second brake shoes into radial engagement with a drum.

Abstract: A method and device for driving at least one electromagnetic load, in particular a solenoid valve, for controlling an injection of fuel into an internal combustion engine, using a drive circuit equipped with an electronic switching device and at least one booster capacitor. The booster capacitor includes a recharging device that recharges a voltage of the booster capacitor to a desired voltage value influencing an opening speed of the solenoid valve, and thus an injection time, each time the booster capacitor is partially or completely discharged. The recharging device is functionally connected to a detecting device for detecting at least a speed and a load of the internal combustion engine. The recharging device includes a regulating device that regulates an intensity of a recharging current needed for the desired voltage value and the necessary recharging time, at least as a function of the speed and the load detected by the detecting device.

Abstract: A plug connection having a first connector, which can be sealingly coupled to a second connector, is designed such that contact elements of the first connector are secured axially and the unit volume of the plug connection is small. The first connector has contact elements , which, in an end area that is facing the second connector, support locking bodies, which can be overlapped axially in a form-locking manner by a locking element that is movably supported on the first connector. A seal that generates the seal between the two connectors is mounted in the locking element axially downstream and therefore in the spatial vicinity of the end area, as a result of which a pot-shaped plug-in receptacle of the second connector that overlaps the seal is of small axial dimensions. The locking element, if not correctly inserted may block mating of the first and second connectors. This plug connection may advantageously be used in motor vehicles in cramped installation circumstances.

Abstract: The ohmic resistance of a firing element connected in series to a capacitance is measured by charging the capacitance with a measured current for a specifiable charging time, by recording a first firing circuit voltage which drops at the firing circuit at the end of the charging operation and by recording a second firing circuit voltage after the measured current is disconnected and by determining the resistance of the firing element from the two firing circuit voltages and the measured current. An exact measurement of the resistance of the firing element regardless of capacitance fluctuations is made possible in that the charging time for the capacitance of the firing circuit is rated in such a way that the second firing circuit voltage corresponds to a setpoint value.

In particular, the at least one operating-dynamics variable includes a variable describing the yaw rate of the vehicle. The device includes arrangements which are used for determining whether an actuation of a parking brake contained in the vehicle exists above a predefined value for the vehicular speed.
