Abstract
In an approach to active engine idle control, an apparatus comprises: an accelerator module interface; an engine control module (ECM) interface; a computer readable storage media; and a controller. The controller is configured to: determine an engine speed target for a vehicle engine in revolutions per minute (RPM) based on an electrical load on the vehicle; determine a voltage curve for one or more position sensors of an accelerator module in the vehicle; determine a voltage target for the ECM for each position sensor of the one or more position sensors; and responsive to a first signal that the apparatus is engaged and a second signal that the vehicle is stopped, set an input voltage to the ECM at the voltage target for each of the one or more position sensors.
Claims15
An apparatus for active engine idle control for a vehicle, the apparatus comprising:
- an engine control module coupled to an engine of the vehicle;
- and
- an active idle control module coupled to the engine control module, the active idle control module configured to:
- determine an engine speed target to the engine in revolutions per minute (RPM) based on an electrical load on the vehicle, wherein the engine speed target is a minimum engine RPM at which a generator output meets or exceeds an electrical demand of the vehicle;
- and
- responsive to determining that the vehicle is stopped, provide an engine control output to the engine control module to operate the engine of the vehicle at the minimum engine RPM at which the generator output meets or exceeds the electrical demand of the vehicle.
