Abstract: An auxiliary engine control unit for use with a main engine control unit for an internal combustion engine of a vehicle may have an input signal interface unit. The input signal interface unit may be configured to intercept at least one engine control output signal of the main engine control unit. The auxiliary engine control unit may also have a control unit which is configured to change the intercepted engine control output signal according to a control scheme stored in the control unit. The auxiliary engine control unit may also have an output signal interface unit which is configured to output the engine control output signal, changed by the control unit, to the internal combustion engine to be controlled in order to achieve an improved control of the internal combustion engine.

Abstract: The invention relates to an engine control unit (1, 1?) for an internal combustion engine of a fleet vehicle (2, 2?) in a vehicle fleet with at least two fleet vehicles (2, 2?) with a control unit (3, 3), which is configured for setting control variables based on measured variables according to a control scheme stored in the engine control unit (1, 1?); and with a data interface unit (4, 4?), which is configured to transmit respective engine operating data sets to/from another engine control unit (1, 1?) of a respective drive internal combustion engine of at least one other fleet vehicle (2, 2?); wherein the control unit (3, 3?) is configured to set the control variables while considering at least one engine operating data set of the other engine control unit(s) (1, 1?) received via the data interface unit (4, 4?), in order to provide an improved control for the internal combustion engine.

Abstract: The invention relates to a motor controller for an internal combustion engine of a vehicle, comprising a control unit for setting one or more control variables on the basis of one or more measured variables according to a stored control scheme; wherein the control unit is designed to modify the stored control scheme when the control unit is used as intended with the operational internal combustion engine, which is being controlled by the motor controller, according to a specified learning algorithm, namely using at least one feedback parameter which is associated with an optimization criterion and is provided to the control unit, in order to provide an improved control of the internal combustion engine.

Abstract: A system for navigation of an autonomously navigating submersible body during entry into a docking station below the water surface includes a determiner for determining an actual motion vector of the autonomously navigation submersible body in relation to the set motion vector describing the optimum entry direction into the docking station and a calculating unit. The calculating unit serves to determine the deviation between the actual motion vector and the set motion vector to determine control vectors based on the deviation and to thereby control the autonomously navigating submersible body during entry.

Abstract: A method and an apparatus for object recognition, in particular defect detection on workpieces, such as shot cores (1) or core packets, wherein the object is illuminated by a light source (4) and recorded and detected by means of a camera (3), and wherein the data obtained from the recording are processed or, if need be, stored by means of a computer. The object is illuminated by a least two light sources (4) from different directions or angles, and the camera (3) records the object and the shadows resulting from the illumination.

Abstract: A method for determining a helical groove structure, for example in the form of flutes, in the surface of a finely finished cylindrical workpiece, in particular the ground mating bearing surface of radial shaft sealing rings, which is characterized in that a camera is used to record at least one image of the illuminated surface of the workpiece, which image reproduces the helical groove structure in the surface of the workpiece. A device for carrying out a method includes a CCD camera with a macrolens, a radial bearing device for the workpiece, an illuminating device and an image reading and image processing device.

Abstract: Cores (1) are joined to form a core assembly used in foundry practice, with the cores being joined to each other at connecting areas (2) formed by interconnected male and female portions (4, 5). A clamping member (3) is positioned between the male and female portions to produce a clamping effect therebetween.
