Patent DE-4011199-A1 (DE)
Title: IC engine management system for vehicle - has processor control which alters all parameters progressively to minimise fuel use
Inventor: BEHRENS MARTIN
IPC: F02P5/04
Filed: 1990-04-04
Abstract: The processor control for the engine management system alters the different engine parameters to reduce fuel burn.  Each parameter is altered progressively and in turn with the engine speed constant. When the engine speed alters the control sequence starts again. A first stage weakens the mixture while a second stage advances the ignition.  Third and fourth stages weaken the mixture and advance the ignition while a final stage enriches the mixture.  If the engine speed is maintained then the control the sequence re-runs from the second- to fourth stage, if the speed is altered the entire sequence is restarted. ADVANTAGE - Solid state processor control, improved running efficiency.

Patent DE-4033974-A1 (DE)
Inventor: BREIL JUERGEN DR ING
IPC: B29C48/10
Filed: 1990-10-25
Abstract: In prior art processes of this kind the actual thickness of the extrudate is measured, compared with a reference thickness and the setting regions of an extrusion plant are controlled dependently upon the degree of difference. In order nevertheless to improve the quality of the extrudate in relation to the desired reference thickness, according to the invention the evolution strategy process is used. An increase in the convergence rate can also be attained by taking into account strategy parameters which can be deterministically or stochastically changed, whereby mixing including fixedly settable strategy parameters is also possible. In particular, knowledge of the process can be involved as qualitative process partial knowledge.
