摘要： A crank angle sensor that outputs a crank angle signal at a predetermined crank angle by synchronizing rotation of a signal rotor fixed on a crank shaft of an internal combustion engine, an interval of the crank angle signals being longer at a specific crank angle corresponding to a position of a crank position reference part of the signal rotor, includes a backward rotation detecting function that outputs different crank angle signals in a forward rotation of the crank shaft and in a backward rotation of the crank shaft, and a control part disallows the detection of the crank position reference part when a stop request to the internal combustion engine is generated or when the backward rotation of the crank shaft is detected based on the crank angle signal, and controls the internal combustion engine by calculating the crank angle based on the crank angle of the crank position reference part detected before the detection of the crank position reference part is disallowed and the crank angle signal.

摘要： A control system for fuel injection by predicting engine noise may include an engine noise predicting device configured to derive a predicted engine noise value in real time by a predicted engine noise coefficient which is pre-stored according to a currently measured combustion pressure value of an engine; and a combustion controller configured to determine a difference between the real-time predicted engine noise value derived by the engine noise predicting device and a target engine noise value for a current operation condition of the engine, and when the engine noise is determined as being degraded due to an abnormal combustion, configured to change the target engine noise value to control fuel injection according to the changed target engine noise value.

摘要： Methods and systems are provided for reducing driver dissatisfaction from NVH associated with cylinder deactivation. Audio and video feed is captured from inside a vehicle and analyzed to infer if a vehicle operator is distracted. If yes, then a VDE transition is scheduled to occur during the time when the driver is distracted and unlikely to notice the NVH.

摘要： Methods and systems are presented for improving engaging automatic vehicle motive power source stopping and inhibiting automatic vehicle motive power source stopping. The methods and systems include processing driver inputs in a machine learning model and characterizing the driver in one of a plurality of driver groups. Automatic vehicle motive power source stopping and starting may be adjusted responsive to a group in which a driver is a member.

摘要： Methods and systems are provided for operating a split exhaust engine system that provides blowthrough air and exhaust gas recirculation to an intake passage via a first exhaust manifold and exhaust gas to an exhaust passage via a second exhaust manifold. In one example, an intake valve timing, exhaust valve timing of a first set of exhaust valves coupled to the first exhaust manifold, and a position of an exhaust gas recirculation (EGR) valve in an EGR passage may be adjusted in coordination with one another in response to a condition at a compressor. The EGR passage may be coupled between the intake passage, upstream of the compressor, and the first exhaust manifold.

摘要： Systems and methods (e.g., a method for controlling and/or operating a compressor) are provided that includes the steps of monitoring a crankcase pressure of a first compressor; analyzing the monitored crankcase pressure that includes calculating an average of the crankcase pressure over a time period and comparing the average of the crankcase pressure over the time period to a nominal crankcase average pressure; identifying a condition of the first compressor based on the analysis of the monitored crankcase pressure; and adjusting operation of a second compressor to compensate for the first compressor in response to identifying the condition of the first compressor based on the analysis of the monitored crankcase pressure. (The method may be carried out automatically or otherwise by a controller).

摘要： Systems and methods for operating an engine with a plurality of deactivating valves for deactivating engine cylinders are presented. In one example, a plurality of different cylinder operating modes may be available to operate the engine. Engine fuel consumption in each of the plurality of different cylinder operating modes is estimated and the engine may be operated in the cylinder mode that provides greatest fuel efficiency.

摘要： Systems and methods for operating an engine with deactivating and non-deactivating valves is presented. In one example, the engine may include non-deactivating intake valves, deactivating intake valves, and only non-deactivating exhaust valves. The non-deactivating exhaust valves may operate to open and close during an engine cycle while deactivating intake valves remain closed during the engine cycle to prevent air flow through selected engine cylinders.

摘要： An engine system incorporating an intake manifold, a compressor, and a controller. The compressor may provide air to the intake manifold and the controller may be connected to the intake manifold and the compressor. The controller may receive a control signal and control air flow from the compressor to the intake manifold based on the received control signal. The controller may control the air flow from the compressor to the intake manifold based on a first equation when a value related to the control signal is on a first side of a threshold and according to a second equation when the value is on a second side of the threshold. The controller may control the air flow between the compressor and intake manifold according to the second equation to prevent the compressor from operating at a surge condition when controlling the air flow according to the first equation.
