| titleOfInvention | PROCEDURE FOR ADJUSTING THE CATALYST OXYGEN STORAGE CAPACITY |
| abstract | A method for a vehicle comprising: Determining an oxygen storage capacity (OSC) period (340) of a catalytic converter (136) of an exhaust system (134) based on first and second amounts of oxygen measured using first and second oxygen sensors (176, 177) located upstream and downstream, respectively. downstream of the catalytic converter (136), wherein determining the OSC period (340) comprises selectively instructing a change in fuel delivery (272) of an engine (102) from a fuel rich state to a fuel lean state; determining a first period between a first time when the switch is instructed and a second time when the first amount of oxygen crosses a first predetermined value; determining a second period between the first time and a third time at which the second amount of oxygen crosses a second predetermined value; and determining the OSC period (340) for the catalyst (136) based on the first and second periods; Determining a delay period (352) of the second oxygen sensor (177) based on the second amount of oxygen being monitored; determining an area (360) under a curve shaped by the second amount of oxygen between the first time and a fourth time when the second amount of oxygen crosses a third predetermined value; a filtered area (364) using the area (360), N previous values of the Determining the area (360) of N previous transitions from the fuel rich state to the fuel lean state and a filter; and determining the delay period (352) based on the area (360) or the filtered area (364); Setting a corrected OSC period (348) for the catalyst (136) based on a difference between the OSC period (340) and the delay period (352); and selectively indicating that there is a failure in the catalytic converter (136) based on the corrected OSC period (348). |
