Appeal No. 1996-3356
Application No. 08/235,668
BACKGROUND
Appellants' invention relates to a method for forming an actuating variable where
various sensor measurements are determined at times which are at periods being equal to
or a multiple of the output period of the actuating variable and forming the actuating
variable in each output period from all of the individual components with values being valid
in that output period. Not all data is updated or measured each output period and slower
changing data is sampled at a slower rate than faster changing data.
Representative Claim
Claim 1 is a representative of the claimed subject matter and read as follows:
1. In a method for forming an actuating variable to be output periodically by a control
unit in output periods for controlling an apparatus, which includes reading output
signals of at least two sensors into the control unit and ascertaining individual components
of the actuating variable based on the output signals, the improvement which comprises:
reading in the sensor output signals and determining the individual components
periodically at intervals of one read-in period or one determination period being equal to or
a multiple of the output period of the actuating variable;
adjusting the read-in period of a sensor output signal to be dependent on a speed of
variation of the sensor output signal;
adjusting the determination period of each individual component to be dependent on the
read-in periods of the sensor output signals involved in each individual component; and
forming the actuating variable in each output period from all of the individual components
with values being valid in that output period.
