ELECTRONIC THROTTLE CONTROL ALGORITHM THAT DETERMINES WHETHER A THROTTLE IS PROPERLY RESPONDING TO THROTTLE COMMANDS

摘要

A system and method for determining when a position of a throttle (24) is not adequately conforming to a command signal provided by a control module (32), such that a fault indication should be provided, is disclosed. The system includes a throttle assembly (20) including the throttle, which is configured to generate a position signal indicative of the position of the throttle, and a processor (34) that is coupled to the throttle assembly and is configured to receive the command signal and the position signal. The processor is further configured to determine a first limit that is functionally dependent upon the command signal, the first limit delimiting an acceptable range of throttle positions from a first unacceptable range of throttle positions, and to determine that the position of the throttle is not adequately conforming to the command signal when the position of the throttle as indicated by the position signal is in the first unacceptable range of throttle positions.
