The map in this example is set up to provide a deadband
in the center (points D and E) and less sensitivity at the
ends (between A and B, and between G and H).
The steer command map is shaped by points A – H.
A command map is used in the input command signal flow to compensate for
steering geometry differences between vehicles (steered wheel on the left side,
middle, or right side).
The command map menu contains 14 parameters defining an 8-point
map that modifies the steer command input. The first point (Left Stop (deg))
always defines the steer command input of -100% and the last point (Right
Stop deg)) always defines the steer command input of 100%.
