Setting Up a Feature Calibration

A feature calibration is the process of calibrating lookup tables and their normalizers by comparing a collection of lookup tables to a model. The collection of lookup tables is determined by a strategy.

A feature refers to the object that contains the model and the collection of lookup tables. For example, a simple feature for calibrating the lookup tables for the maximum brake torque (MBT) consists of

• A model of MBT
• A strategy that adds the two following tables:
• A speed (N), load (L) table
• A table to account for the behavior of the air-fuel ratio (A)

Having already set up your variable items and models, you can follow the procedure below to set up your feature calibration:

1. Add a feature. This is described in the next section, Adding a Feature.
2. Assign a model. This is described in Assigning a Model.
3. Set up your strategy. This is described in Setting Up Your Strategy.
4. Set up the tables. This is described later, in Setting Up Tables.

This section describes steps 1, 2, and 3 in turn.

When you have completed these four steps, you are ready to calibrate the normalizers, tables, and features.
