Appeal No. 99-0717 Page 3
Application No. 08/597,095
BACKGROUND
The invention at issue in this appeal controls the idle
speed of an engine. More specifically, it employs an
electronic engine control module executing a neural network
program to control an internal combustion engine. An external
training processor derives weight values, which determine the
manner in which network signals are combined. The weights are
stored in a data structure.
Claim 1, which is representative for our purposes,
follows:
1. Apparatus for controlling the idle speed of an
internal combustion engine, said engine including an
ignition timing control and a throttle, said
apparatus comprising, in combination:
sensing means coupled to said engine for
producing a plurality of input signal values, each
of which is indicative of a corresponding one of a
plurality of engine operation conditions, said
conditions including engine speed and the rate at
which intake air is being delivered to said engine,
data storage means for storing a neural network
definition data structure which defines a neural
network, said structure including:
signal value data defining said input
signal values and the values of signals being
processed by said neural network, and
weight values governing the manner in which
signals are combined within said neural network,
and
