CONTROL FUNCTIONS (CONT’D)

Application Interface Outline

Droop selection feature (switching droop-isochroous control)

The Eco-governor can switch the Isochroous control and the virtual droop control by external switch. By default, when external switch is not connected (when ECUterminal APP-IP1 [E24] is open), it is set that it becomes the virtual droop control.By option, changing the logic setting of APP-IP1 terminal enables the isochroous control to be set when external switch isn’t connected.See [Figure 10-40-17] for details.

Isochroous control at low idling

As shown in [Figure 10-40-23], it’s possible to make the engine speed (target speed) not go below the low idling speed even when virtual droop is selected (optional).
