EXHAUST SYSTEM HAVING SENSOR PLACEMENT DETECTION

摘要

An exhaust control system for use with a combustion engine is disclosed. The system may have an exhaust passage, an exhaust sensor located within the exhaust passage and configured to generate a first signal indicative of an exhaust parameter, and an operational sensor associated with the combustion engine and configured to generate a second signal indicative of an operational parameter. The system may have a controller associated with the combustion engine, the exhaust sensor, and the operational sensor. The controller may be configured to detect a change in the operational parameter based on the second signal and to detect a change in the exhaust parameter based on the first signal. The controller may measure an elapsed time between detection of the change in the operational parameter and the change in the exhaust parameter, and determine a placement-related parameter of the exhaust sensor based on the elapsed time.

1. An exhaust control system for use with a combustion engine, comprising:
an exhaust passage configured to receive a flow of an exhaust gas from the combustion engine; an exhaust sensor associated with the exhaust passage and configured to generate a first signal indicative of an exhaust parameter of the exhaust gas; an operational sensor associated with the combustion engine and configured to generate a second signal indicative of an operational parameter of the combustion engine; and a controller associated with the combustion engine, the exhaust sensor, and the operational sensor, the controller being configured to:
detect a change in the operational parameter of the combustion engine based on the second signal;detect a change in the exhaust parameter of the exhaust gas based on the first signal;determine an elapsed time between detection of the change in the operational parameter and the detection of change in the exhaust parameter; anddetermine a placement-related parameter of the exhaust sensor based on the elapsed time.
