Abstract: A method and a device for detecting an imminent rollover of a vehicle. The method comprises taking a series of images of the surroundings of the vehicle, in particular of the road ahead, with a camera; determining and tracking point features in the series of images; eliminating point features which are located on objects that move relative to the stationary surroundings of the vehicle; and computing at least one parameter of the rotational movement of the camera (roll, pitch and/or yaw rate) taking into account the remaining point features.

Abstract: The invention relates to a method for increasing the bending strength and the endurance limit of crankshafts by locally restricted hammering in areas of high stress, such as grooves, the mouths of bores and cross-sectional transition zones, in which method pressure impulse machines or beating devices comprising heating tools are employed. The pressure impulse machines or beating devices only execute a relative displacement of the beating tool against the surface of the crankshaft segment to be processed when the compressive stress is introduced between the heating tool and said surface of the crankshaft segment to be processed. The invention also relates to a device for increasing the endurance limit of crankshafts.

Abstract: In a method for increasing the strength of a component subjected to torsional and flexural stress, in particular of a crankshaft, in a first step essentially the entire component is provided with a nitriding layer. In a second step, the nitriding layer is at least partially removed in at least one highly stressed region of the component by means of cutting machining, and, in a third step, the at least one highly stressed component region freed of the nitriding layer is mechanically strain-hardened.
