摘要： The invention relates to a circuit arrangement and device for regulation and control of the speed of a motor vehicle, comprising a functional group for control of the speed, corresponding to a pre-set value given by the driver and a functional group to limit the speed by controlling and/or regulating intervention at a limiting value determined by the driving conditions, pre-set criteria and the set-speed. Said circuit arrangement (4) for regulation and control of the speed is arranged as part of a complete system (1 to 4), comprising an ABS, an ASR, an ESP and similar systems and evaluates regulatory parameters from the wheelslip control systems (1 to 3) to limit the speed in pre-set situations.

摘要： The invention relates to a method for operating a driver support system for motor vehicles. The aim of the invention is to provide support for the driver of a motor vehicle in all traffic conditions in a simple, low-cost manner, without placing excessive demands on said driver. According to said method, during the following mode, in which the speed of the motor vehicle is regulated depending on its distance from detected target objects that are classified as relevant, the relevant target objects used for said speed regulation are selected by the driver of the motor vehicle by actuating a user control.

摘要： The invention relates to a method for determining the distance between a reference object and at least one target object by means of timing the interval between transmission and return of the reflected signal. The aim of the invention is to provide a simple, economical means of determining the distance between a reference object and at least one target object located in the range of observation and/or the speed and/or the acceleration of at least one target object located in the range of observation with a high degree of accuracy. The transmitting unit that is used to emit a pulse-type transmission signal is controlled in a clocked manner with a first control signal and the receiving unit used for detecting the resulting reflective signal is controlled in a clocked manner by a second control signal in order to sample the reflected signal at specific sampling points. The second control signal is phase-shifted in relation to the first control signal in such a way that the distance deviation between the distance to the target object determined based on the interval between the transmission and return of the reflected signal and the actual distance to the target object is minimized. The invention also relates to a method for supporting driver assistance systems for automobiles.

摘要： The invention relates to a method for detecting a fault in a pressure-switch arrangement (4). According to said method it is always assumed that there is at least one fault in the pressure-switch arrangement (4) when a signal occurs at an input (II) of an electronic calculating unit (I) which is not associated with the opened or the closed state of the pressure switch (4). It is also assumed that there is a fault on the pressure-switch arrangement (4) installed in a vehicle brake system when the pressure-switch signal indicates that the brake is being actuated, but the vehicle accelerates significantly. Alternatively, a fault is also assumed when the vehicle decelerates sharply but the pressure-switch signal indicates a lack of brake pressure. The invention proposes a suitable pressure-switch arrangement which generates a square wave signal (2) when the pressure switch (4) is closed, and a high-level signal at an input (II) of an electronic calculating unit when the pressure switch is opened. When a low-level signal occurs, it is assumed that the pressure-switch arrangement (4) has a fault.

摘要： The invention concerns the external connection of a voltage regulator in a motor vehicle power supply, the power input (2) of the voltage regulator (1) being connected via a dual diode (7, 10) both to the main line (6), which is connected to the positive pole of the battery, and to an auxiliary line (9) which is connected to the positive pole of the vehicle power supply network by means of an ignition switch. The auxiliary line (9) is connected to a buffer capacitor (12). In the event of a voltage collapse on the main line (6), the power input is fed via the auxiliary line or by means of a current flowing from the buffer capacitor (12). In the event of a voltage collapse on the auxiliary line, the signal input (4) is fed via the buffer capacitor (12) which is dimensioned to buffer the power input (2).

摘要： Disclosed is a piezo-electrically actuated fluid valve with a valve housing (1) in which a valve chamber (2) is formed and a piezo-electric bending converter (3) is fixed on one side and undergoes stress. The valve housing (1) is fitted with a first and second junction canal (4, 5) between an outer connecting point (6, 7) and an opening (8, 8a) in the valve chamber (2) in addition to a valve seat (9) on one of the openings (8, 8a) and a valve member (10) actuated by and interacting with the bending converter (3). According to the invention, the valve member (10) has a tappet (11) with tight surfaces (12) whose rear end is connected to the non fixed end of the bending converter (3) and whose front end is sealed and guided into a through hole (13) extending perpendicular to the valve seat (9). Inside the tight zone, the through hole (13) forms a partial section of one of the junction canals (4) and the free front surface (15) of the tappet (11) outside the tight zone is exposed to the same fluid pressure as that which prevails in the other junction canal (5).

摘要： Using the signals from tyre sensors to adjust the driving performance of a motor vehicle is known. For example, contact sensors can be used to determine the forces applied to individual vehicle tyres. To enable action to be adjusted in the shortest possible real time, the invention proposes to use the forces determines by the signals from tyre sensors as a regulating variable. This means that the projected status's of the motor vehicle are converted into projected forces Fi,Soll which are compared with the actual forces Fi,Ist being applied. The thus calculated differences in forces ΔFi are then converted by a wheel-force regulator (2) for example into changes in brake pressure or changes in the motor torque which then influence the motor vehicle (3) within a controlled system. As the forces Fi,Ist affecting the vehicle tyres, that are to be determined as quickly as possible, are quantities that describe the driving status of the vehicle, the reaction time of the system is extremely short and therefore driving performance can be better adjusted.

摘要： A circuitry for recognising a fault or leakage current in a supply line (REF) of an electronic circuit contains a current source (IQ; +IG, -IQ) designed for a maximum admissible fault or leakage current (+/- Imax). The current source is supplied by an auxiliary voltage source (UH). The potential in the supply line (REF) when the leakage current causes the supply voltage (UB) to be switched off is determined and evaluated by a potential monitor (PM1).
