Abstract: In order to be able to perform redundant measurements of rotation rates particularly economically, disclosed herein is a sensor device which includes a dual-axis, first rotation rate sensor element with which rotation rates of rotating motions of the sensor device about a first and a second rotation rate measurement axis can be detected, wherein the first and the second rotation rate measurement axes are oriented orthogonally in relation to one another. The sensor device is defined by the fact that the sensor device includes at least one other rotation rate sensor element with which a rotation rate of a rotating motion of the sensor device about a rotation rate measurement axis, which lies in a plane together with the first and the second rotation rate measurement axes, can be deselected.

Abstract: A master cylinder 1, especially for a controlled brake system, includes at least one piston 3, 4; 53, 54 displaceable in a housing 2, which is sealed in relation to a pressure chamber 7, 8 by means of a sealing element 5, 6 arranged in an annular groove 23, 24 of the housing 2, said pressure chamber being connectable to an unpressurized supply chamber 11, 12 by means of transverse bores 9, 10; 50, 51 provided in the piston 3, 4; 53, 54. Several recesses 15, 16, 17 are arranged on an inside surface 13, 14; 59, 60 of the piston 3, 4; 53, 54 into which the transverse bores 9, 10; 50, 51 open.

Abstract: In a method for determining at least one, preferably however several driver-independent interventions in a vehicle system, a risk calculator is used, whose input is supplied with predetermined vehicle data, ambience data, current vehicle and driver data, occupant data or data of persons outside the vehicle, or similar data. The risk calculator issues an evaluation of the risk situation of the vehicle and its occupants or the persons outside the vehicle based on said data and, in accordance with the evaluation and optional additional criteria or weightings, outputs driving signals controlling actuators that modify or trigger the driving behavior of the vehicle and/or the occupant protection system and/or protection means for other traffic participants (pedestrians, cyclists, etc.) in such a way that maximum protection is obtained for the persons and the vehicle according to a priority control.

Abstract: A method for monitors the functions and increases the operational reliability of a complex safety-relevant control system. Examples of such control systems include motor vehicle control systems such as a brake system (ABS, TCS, ESP, EHB, EMB), a steering aid (“steering-by-wire”), etc. The method also detects and evaluates system errors. The method detects a system error and evaluates as a group error, brings about a complete system degradation or a partial system degradation corresponding to the group error, e.g. limitation of the system functions and the system availability, localizes the system error and the error source by tests, logical combining of the test results, plausibility considerations, etc. and gradually cancels the restrictions of the system functions and enhances the system availability in dependence on the result of the individual steps for bounding or localizing the system error and the error source.

Abstract: Disclosed is a tire module for sensing tire condition variables with a spring element (2) clamped on one end and a converting unit (2, 3, 4, 6, 7), in which kinetic energy is converted into electric energy. The spring element (2) is a bar spring, torsion spring, or leaf spring, with a seismic mass (3) being arranged at the end of the spring element that is not clamped, and the spring element transmits acceleration jumps of the seismic mass (3) to the converting unit (2, 3, 4, 6, 7).
