Abstract
A control system is provided. This system generally includes a table datastore that stores data in a table format wherein the table format includes a plurality of zones. A data storage module stores learned data to one or more of the plurality of zones. A data access module generates a table output by retrieving the learned data from one or more of the plurality of zones and interpolating between the learned data.
Claims13
A control system, comprising;
- a table datastore that stores data in a table format, wherein the table format includes a plurality of zones;
- a table definition module that initializes each of the plurality of zones to a predetermined value that indicates that the value in the zone has not been learned;
- a data storage module that replaces a plurality of the predetermined values with values learned during operation of a vehicle;
- and
- a data access module that determines a location of a zone in the table format based on input parameters, that retrieves learned values from zones nearest the location when the value in the zone corresponding to the location is equal to the predetermined value, and that generates a table output by interpolating between the learned values retrieved from the zones nearest the location.

A method of interpolating data from a table in memory, comprising:
- storing data in a table format, wherein the table format includes a plurality of zones;
- initializing each of the plurality of zones to a predetermined value that indicates that the value in the zone has not been learned;
- replacing a plurality of the predetermined values with values learned during operation of a vehicle;
- determining a location of a zone in the table format based on input parameters;
- traversing zones in the table format for learned values nearest the location;
- retrieving learned values from zones nearest the location when the value in the zone corresponding to the location is equal to the predetermined value;
- and
- generating an output based on an interpolation between the learned values retrieved from the zones nearest the location.
