Curtis 1244 - Fig. 17: Throttle Maps for Controller with Maximum Speed Set at 80% and Creep Speed Set at 10; Fig. 18 Influence of Various Parameters on Controller Output Response to Throttle Demand

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.
