摘要： A monitoring module selectively generates a request to at least one of: transition from providing rich fueling an engine to operating the engine in a fuel cutoff (FCO) state; and transition from operating the engine in the FCO state to providing rich fueling to the engine. In response to a response to the request, the monitoring module: selectively controls fueling to the engine to perform the at least one of the transitions; and selectively determines whether a fault is present in a component based on a response to the at least one of the transitions. A hybrid control module controls an electric motor of the hybrid vehicle and that selectively generates the response.

摘要： An engine control system comprises an air control module and a spark control module. The air control module controls a throttle valve based on a first desired torque when the throttle valve is in an operable state. The spark control module controls spark advance based on the first desired torque and a second desired torque when the throttle valve is in a fault state. The throttle valve is maintained in a predetermined fault position when in the fault state.

摘要： An engine control system includes a desired manifold absolute pressure (MAP) module, a MAP to torque module, a threshold determination module, and a fuel economy (FE) mode module. The desired MAP module determines a desired MAP for operation of an engine in one of a cylinder deactivation mode and a low-lift mode based on a difference between a desired vacuum and an air pressure upstream of a throttle valve. The MAP to torque module determines a desired torque output of the engine for operation in the one of the cylinder deactivation mode and the low-lift mode based on the desired MAP. The threshold determination module determines an entry torque based on the desired torque output. The FE mode module selectively triggers operation in the one of the cylinder deactivation mode and the low-lift mode based on a comparison of the entry torque and a torque request.

摘要： A system for a vehicle includes a fuel control module and a voltage setting module. The fuel control module cuts off fuel to an engine during a deceleration fuel cutoff (DFCO) event. During the DFCO event, the voltage setting module monitors a brake pedal position, sets a desired voltage to a first predetermined voltage when a brake pedal is not depressed, and sets the desired voltage to a second predetermined voltage when the brake pedal is depressed. The second predetermined voltage is greater than the first predetermined voltage. A regulator generates a pulse width modulation (PWM) signal based on the desired voltage and applies the PWM signal to an alternator.

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 position 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 control system includes a throttle control module, an exhaust gas recirculation (EGR) control module, and a diagnostic control module. The throttle control module selectively maintains a desired throttle area when a vehicle is in a coastdown mode. The EGR control module opens an EGR valve when the desired throttle area is maintained. The diagnostic control module selectively diagnoses an error of an EGR system based on a pressure increase measured in an intake manifold of the vehicle when the EGR valve is open.
