    摘要: A control system for an engine having a catalytic converter includes an energy calculation module that calculates a calculated mass air flow (MAF) of intake air of the engine based on a requested torque and a requested spark timing that correspond to a desired thermal energy of exhaust of the engine, and that determines an expected thermal energy of the exhaust based on the calculated MAF, and an energy residual module that determines a thermal energy residual of the exhaust based on the expected thermal energy and an estimated thermal energy of the exhaust, wherein the estimated thermal energy is based on a measured MAF of the intake air. The control system includes an energy evaluation module that determines a diagnostic result that indicates whether the catalytic converter is operating within a target temperature range based on the thermal energy residual. Related control methods are also provided.

    摘要: An engine control system comprises a pedal torque request module, a filtering module, a selection module, and an arbitration module. The pedal torque request module determines a first pedal torque request at a first time and determines a second pedal torque request at a second time. The first time is before the second time. The filtering module determines a filtered pedal torque request based on the first pedal torque request, the second pedal torque request, and a filter coefficient. The selection module selects one of the second pedal torque request and the filtered pedal torque request. The arbitration module arbitrates between at least one driver torque request and the selected one of the second pedal torque request and the filtered pedal torque request, outputs a raw driver request based on a result of the arbitration, and controls at least one engine actuator based on the raw driver request.
