IDLE REDUCTION SYSTEM AND METHOD

摘要

The present concept is method of controlling a vehicle's engine idle and includes the steps of monitoring a vehicles operating parameters with a controller and comparing parameters to preselected shutdown conditions. In the event shutdown conditions are met and the key is not in the ignition, the controller warns operator of impending shutdown. The controller intercepts the ignition key signal and simulates the vehicle key to be in the run position such that vehicle functions are operable as if key is in run position. The controller shuts down engine. The method may also include the steps of: the controller intercepting the ignition key signal and simulating the vehicle key to be in the accessory position such that vehicle functions are operable as if key is in accessory position.

1. A method of controlling a vehicle's engine idle while the vehicle is at rest, comprising the steps of:
a) placing the vehicle transmission to a position selected from among park or neutral; b) shut down engine by turning key to the off position and removing the key from the ignition; c) driver exits the vehicle; d) monitoring a vehicles operating parameters with a controller and comparing preselected operating parameters to preselected startup conditions; e) in the event preselected startup conditions are met the controller intercepts key position signals from the ignition and sends the key run position signal to the on board computer thereby enabling vehicle functions operable as if the key is in run position; f) the controller starts up the engine and the engine idles with the vehicle at rest.
