Abstract: A multi-pole electrical connector is to be designed such that it is usable under cramped installation conditions and can be cost-effectively produced. The connector has a contact set having a plurality of contact elements, each of which has a connecting section and a contact section. Both the connecting sections and the contact sections are formed from a single-layer stamped grid and are arranged in one plane. This connector is provided for use in the automobile industry, particularly in fuse boxes and electrical-system control units of motor vehicles.

Abstract: A device for reliably generating signals, which includes a control means (10) that is supplied a control signal (12). The control means (10) generates a trigger signal (13, 14) as a function of the control signal (12), in order to trigger a load (50). Emergency operating means (30, 32) are provided, which, in an emergency operation, generate the trigger signal (34, 14) as a function of the control signal (12).

Abstract: A method is used to largely suppress the offset of a rotation rate sensor in that a given rotation rate is only subjected to integration if it exceeds a lower rotation rate threshold and lies below an upper rotation rate threshold. The thresholds are predefined as a function of an offset of the rotation rate sensor in question, and integration of the rotation rate is aborted after a predefined reset time and restarted.

Abstract: The invention relates to a method for actuating closing part systems with actuators (8) in motor vehicles. The actuators (8) in motor vehicles can be electrically or hydraulically operable drive mechanisms. The closing part components are optionally monitored by means of pinch prevention detectors (10) and adapters (17), which take external disturbance variables (2, 3) into account. In the case of controllers (27) of closing part systems, a vehicle inclination signal N&agr; (24), upon ascertainment of the controlling variable (5) Y(t), and in the case of regulators (20) a reference signal Xr(t) (15), is switched to a pinch prevention detector (10) downstream of them, which reference signal is modified by the vehicle inclination signal (27).

Abstract: So that an arrangement may decide to trigger a safety device in as error-free and reliable a manner as possible, provision is made for a first arrangement, which derives a first decision criterion for triggering a safety device from the measured turning rate at least about the longitudinal axis of the vehicle and/or from the measured accelerations at least in the direction of the transverse axis and the vertical axis of the vehicle. In addition, a second arrangement is present, which, independent of the first arrangement, derives a second decision criterion. A circuit arrangement then generates a triggering signal for the safety device, when both decision criteria are satisfied at the same time.

Abstract: The method of determining respective rotational position angles (&agr;x,&agr;y,&agr;z) of a vehicle includes measuring respective accelerations (ax, ay, az) of the vehicle (FZ) in the x, y and z directions; calculating first position angle values (&phgr;x1,&phgr;x2) and second position angle values (&phgr;y1,&phgr;y2) from the measured accelerations according to equations (1) and (2): &phgr;x1=arcsin {ay/g} &phgr;y1=arcsin {ax/g}  (1) &phgr;x2=arccos{az/g} &phgr;y2=arccos{az/g}  (2) wherein g is the acceleration of gravity; determining respective inertial position angles (&phgr;x,&phgr;y) as the smaller of the first position angle values (&phgr;x1,&phgr;x2) and of the second position angle values (&phgr;y1,&phgr;y2); measuring corresponding rotation rates (&ohgr;x,&ohgr;y,&ohgr;z) of the vehicle and determining the respective rotational position angles (&agr;x,&agr;y,&agr;z) by integration of corresponding rotation ra

Abstract: To assure that the safety device is triggered at the right time in the event of a lateral collision of the vehicle with a curb, a first comparing device (1) compares a rotation rate (.omega.x) measured relative to the longitudinal axis of the vehicle, or a variable derived from this rotation rate, with a rotation rate threshold value. A second comparing device (2) compares an acceleration (ay), measured in the direction of the transverse axis of the vehicle, with a lateral acceleration threshold value. If both threshold comparing device (1, 2) simultaneously signal that their threshold values are being exceeded, a trigger signal (as1) for the safety device is output.

Abstract: A voltage conversion device is disclosed which is to be used particularly in motor vehicles. For voltage conversion, a plurality of small voltage converters are connected as partial converters parallel to one another. By sequentially turning on the individual partial converters and superposition of the output current, a uniform output current at low input load is attained.

Abstract: In order to allow for a timely and reliable recognition of a rollover event of a vehicle, the angular velocities of the vehicle about the yaw axis, the roll axis, and the pitch axis are measured by way of respective rotation rate sensors. A rollover event is signaled as having been detected if an angular velocity exceeds a definable threshold.

Abstract: A two-battery on-board electrical system in a motor vehicle is disclosed, in which an on-board electrical system control unit is disposed between the batteries, and one battery is used primarily to supply the usual consumers while the other is used primarily to supply the starter. The on-board electrical system control unit 16 includes an on-board electrical system module, which performs the requisite reverse switching operations and has one further terminal, by on-board electrical system components required for starting an operation can be supplied with voltage. These on-board electrical system components are supplied at maximum priority, and if the supply battery is too greatly discharged are jointly supplied by both batteries, but it is nevertheless assured that during the starting process the other on-board electrical system components are not connected to the starter battery.
