    摘要: A method of achieving a desired torque output of an internal combustion engine includes determining a first air-per-cylinder (APC) value based on a first APC relationship and determining a second APC value based on a second APC relationship. An APC error is determined based on the second APC value. Operation of the engine is regulated based on the first APC value when the APC error is greater than a threshold error. Operation of the engine based on the second APC value when the APC error is not greater than the threshold error.

    摘要: A control system for an engine includes an engine torque request module, an engine torque response module, a torque command limit module, and an actuation module. The engine torque request module determines an engine torque request based on (i) an engine power request and (ii) a desired engine speed (DRPM). The engine torque response module determines first and second torque values based on (i) an engine torque response model and (ii) first and second torque boundaries, wherein the first and second torque boundaries are based on the DRPM and a measured engine speed (RPM). The torque command limit module generates a secured engine torque request based on (i) the engine torque request and (ii) the first and second torque values. The actuation module controls at least one actuator of the engine based on the secured engine torque request.
