System and Method For Converting Two Diagnostic States Of A Controller To Three Diagnostic States

摘要

A control system for a vehicle includes a first vehicle system including a plurality of components and a controller. The controller monitors diagnostic data for the plurality of components of the first vehicle system and outputs a two-state status indicator for each of the components of the first vehicle system. States of the two-state status indicator include a failing state and a not failing state. A control module is configured to receive the two-state status indicator and the diagnostic data from the first vehicle system and to convert the two-state status indicator into a three-state status indicator. The three-state status indicator includes a pass state, a fail state and an indeterminate state. The control module is further configured to alter an engine operating parameter based on the three-state status indicator.

1. A control system for a vehicle, comprising:
a first vehicle system including a plurality of components and a controller, wherein the controller monitors diagnostic data for the plurality of components of the first vehicle system and outputs a two-state status indicator for each of the components of the first vehicle system, wherein states of the two-state status indicator include a failing state and a not failing state; and a control module configured to receive the two-state status indicator and the diagnostic data from the first vehicle system and to convert the two-state status indicator into a three-state status indicator, wherein the three-state status indicator includes a pass state, a fail state and an indeterminate state, and wherein the control module is further configured to alter an engine operating parameter based on the three-state status indicator.
