throttle map setting, as the throttle input increases and will reach maximum
output when the throttle input enters the upper deadband (crosses the throttle
max threshold).
Fig. 17 rottle maps for
controller with maximum
speed set at 80% and creep
speed set at 10%.
e rottle Map operates within the window established by the Creep
Speed, Max Speed, rottle Deadband, and rottle Max parameters, as shown
in Figure 18. Creep Speed and Max Speed define the controller’s output range,
while rottle Deadband and rottle Max define the throttle’s active range.
ese four parameters, together with the rottle Map, determine the controller’s
output response to throttle demand.
