    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.

    摘要: A control method for a hybrid powerplant includes receiving a pre-transition signal, and selectively adjusting a combustion torque of an engine of the powerplant between a first torque value and a second torque value prior to a deactivation transition period based on the pre-transition signal, wherein the second torque value is less than the first torque value. The method further includes selectively adjusting an electric drive torque of an electric machine of the powerplant prior to the deactivation transition period based on the pre-transition signal and the combustion torque. The selectively adjusting the electric drive torque includes adjusting the electric drive torque such that a sum of the combustion torque and the electric drive torque is equal to a desired drive torque of the powerplant during a pre-transition period prior to the deactivation transition period. A related control system is also provided.

    摘要: An engine control system includes an inertia phase detection module, a feed-forward (FF) engine speed module, a FF APC module, a FF phaser postion module, and a phaser control module. The inertia phase detection module determines when an inertia phase of a gear shift is occurring within a transmission. The FF engine speed module predicts an engine speed for a future time when the inertia phase ends. The FF APC module predicts an air-per-cylinder (APC) for the future time based on the engine speed. The FF phaser position module determines a FF phaser position based on the engine speed and the APC. The phaser control module controls a camshaft phaser position based on the FF phaser position during the inertia phase of the gear shift.

    摘要: A system includes a power request module, a first desired engine speed (DRPM) determination module, a driver torque request module, and an actuation module. The power request module generates a power request for an engine of the vehicle based on an accelerator pedal position and a vehicle speed. The first DRPM determination module determines a first target DRPM based on the power request, a turbine speed of a torque converter, and a k-factor of the torque converter. The driver torque request module selectively generates a torque request for the engine based on the power request and the first target DRPM. The actuation module controls at least one engine actuator based on the torque request.

    摘要: An engine control system comprises a torque control module and a fueling control module. The torque control module selectively generates a deactivation signal for a first cylinder of a plurality of cylinders of an engine based on a torque request. The fueling control module halts fuel delivery to the first cylinder based on the deactivation signal. The torque control module increases a spark advance of the engine at a first time after the fueling control module halts fuel injection for the first cylinder. The first time corresponds to an initial time combustion fails to occur in the first cylinder because fuel delivery has been halted.

    摘要: A leak detection system for a vehicle fuel tank includes a sensor that is responsive to a pressure within the fuel tank and that generates a pressure signal based thereon. A control module initiates an engine-off natural vacuum (EONV) test and determines a pressure change based on the pressure signal. The control module pauses the EONV test when the pressure change exceeds a pressure change threshold.
