Abstract: A system includes a three-way catalyst (TWC) sulfur load module, a cylinder/fuel cutoff module, a fuel control module, and a valve control module. The TWC sulfur load module is configured to determine an amount of sulfur deposited on a three-way catalyst of an engine in a vehicle. The cylinder/fuel cutoff module is configured to determine whether to enable deceleration cylinder cutoff (DCCO) based on the amount of sulfur deposited on the three-way catalyst. The fuel control module is configured to control a fuel injector to selectively stop fuel injection in the engine when DCCO is enabled. The valve control module is configured to selectively maintain intake and exhaust valves of the engine in a closed position when DCCO is enabled.

Abstract: A method to detect and mitigate sensor or actuator degradation in an automobile system includes: collecting a signal data output from at least one device which is outputting the signal data in response to monitored operational parameters of a motor vehicle system; analyzing patterns of the signal data compared to a signal data output from a nominal operating one of the at least one device using an artificial intelligence program; and identifying when the patterns of the signal data exceed a threshold level indicating the at least one sensor or actuator is operating in a degraded condition.

Abstract: A method to detect and mitigate sensor degradation in an automobile system includes: collecting output signal data from at least one of a sensor and an actuator which is outputting the signal data related to operational parameters of a vehicle system; placing the sensor or the actuator in communication with a fault box used to purposely corrupt the output signal data; analyzing patterns of the output signal data compared to signal data from a nominal operating sensor or actuator using an artificial intelligence program; identifying when a statistical range of the patterns exceeds a first threshold level; and modifying a control signal to change the operational parameters of the vehicle system.
