Abstract: A system and method for providing a fault tolerant vehicle dynamics control (VDC) is described. The system includes a fault tolerance module that receives an indication of a fault in at least one of the actuators of the VDC and selects a fault compensation mode to maintain the stability of the motor vehicle in light of the received fault indication. The fault tolerance module proceeds by diagnosing at least one fault in at least one of the actuators, selecting a fault compensation mode based on the detected at least one fault and the driving condition, and compensating for the at least one fault by optimally controlling remaining operable actuators according to the fault compensation mode.

Abstract: The invention relates to a method for increasing the process stability, particularly the absolute thickness precision and the installation safety during the hot rolling of steel of nonferrous materials, with small degrees of deformation (f) or no reductions while taking the high-temperature limit of elasticity (Re) into account when calculating the set rolling force (Fw) and the respective setting position (s).

Abstract: A method and a device for acquiring performance quantities of a product, in particular until its technical failure, and for determining the remaining service life of the product are described. The determination of the remaining service life of the product, acquisition of service lives of the products and determination of service life threshold values are performed on the basis of performance quantities subdivided into classes (classified). Weighting factors are determined first and then these weighting factors are used to determine weighted, cumulative service lives and service life threshold values. The reliability of products is monitored in mass production.

Abstract: A steering wheel for a vehicle which includes sensors. The sensors are distributed into numerous segments and thus enable the position of an operator's hands on the steering wheel to be detected with high local resolution. The signals supplied by the sensors are analyzed and makes it possible to detect the position of the hands, and the maximum possible steering angle that can be set at the steering wheel without changing the grip. Control actions and control signals can be derived from this information by means of a control.

Abstract: A control device and a method for controlling and/or regulating the operational sequences in a motor vehicle, and a method for starting such a control device, which provide a program in a storage medium of the control device that is able to be executed independently of the frequency of the CPU, which allows the pulse frequency of the CPU to be checked and employs measures for reprogramming the program to be initiated. During starting or operation of the control device, the frequency of the CPU is checked first or the frequency of the CPU is compared to the frequency expected in the program. If necessary, measures for reprogramming the program are subsequently initiated.

Abstract: A method and a device for recording the curve of information. The information is scanned using a specifiable scanning period. The information is specifically the operating data of a motor vehicle. The scanned information is subjected to a data reduction, and then the reduced information is stored. To record the curve of relevant digital information, in particular, of the operating data of a motor vehicle, so as to use the least possible storage space, it is proposed that, in the context of the data reduction, the curve of the scanned information be viewed in a time raster of a multiple of the scanning period, and, within the individual raster increments, at least one characteristic variable of the curve of the scanned information be determined. The device is advantageously a component part of a control device for controlling/regulating specific motor-vehicle components or of an operating- or accident-data recorder of a motor vehicle.
