摘要： Disclosed is a controller of a stepped automatic transmission. The stepped automatic transmission has a plurality of lock-up elements and performs downshift during coasting while an engine has a fuel cut-off state by changing over a pair of lock-up elements including an open side lock-up element and a lock-up side lock-up element. Downshift operation includes torque phase control and inertia phase control. The controller includes: a fuel cut-off recovery executing unit that is configured to perform recovery from the fuel cut-off state for an inertia phase control period; and a cylinder number restricting unit that is configured to restrict a count of cylinders recovered from the fuel cut-off state.

摘要： Methods and systems are provided for diagnosing whether one or more intake air oxygen sensors positioned in an intake of an engine of a vehicle, are functioning as desired. In one example, a method comprises injecting fuel into one or more cylinders of the engine without combustion, routing un-combusted hydrocarbons from the one or more cylinders to the intake via a crankcase ventilation system, and indicating whether the one or more intake air oxygen sensors are functioning as desired based on a response of the one or more intake air oxygen sensors. In this way, the one or more intake air oxygen sensors may be periodically diagnosed which may improve engine operation, and reduce engine degradation, particularly with regard to hybrid electric vehicles with limited engine run-time.

摘要： A method for controlling a powertrain of a vehicle includes calculating, via a controller, an optimal torque target for the powertrain as a function of system limits of the vehicle. The method includes commanding, via transmission of an output torque signal, an actual output torque of the powertrain to pursue or follow the calculated optimal torque target during a steady-state torque request condition. Additionally, the method includes detecting a predetermined vehicle event during the steady-state torque request condition, and shaping the output torque signal via the controller. A variable gain factor may be used in response to detection of the predetermined vehicle event to allow the output torque signal to temporarily deviate from the calculated optimal torque target during the steady-state torque request condition. A powertrain has an engine, an electric machine, and a controller programmed to execute the method.

摘要： A torque management strategy for an HEV having an engine operating with a fixed throttle position to better manage NVH while the vehicle is stationary or decelerating and the engine is generating more torque than a requested torque uses excess engine torque to charge the battery until the requested torque is below a torque loss threshold. Partial fuel injector cut off is avoided to reduce or eliminate associated NVH by adjusting a misfire torque limit to the expected or estimated engine torque produced during operation at the fixed throttle position until the requested torque results in complete fuel cut off to all cylinders.

摘要： Methods and arrangements for controlling hybrid powertrains are described. In one aspect, an engine is alternatingly operated at different effective displacements. One displacement delivers less than a requested powertrain output and the other delivers more. A motor/generator system is used to add and subtract torque to/from the powertrain to cause the net delivery of the requested powertrain output. In some embodiments, energy added and subtracted from the powertrain is primarily drawn from and stored in a capacitor (e.g., a supercapacitor or an ultracapacitor) when alternating between effective displacements. In another aspect a hybrid powertrain arrangement includes an engine a motor/generator and an energy storage system that includes both a battery and a capacitor. The capacitor stores and delivers electrical energy to the motor/generator unit during operation of the engine in a variable displacement or skip fire mode.

摘要： A method for controlling a powertrain includes, in response to an output torque request that includes deceleration, operating an internal combustion engine in a fuel cutoff state and in a cylinder deactivation state, controlling a clutch of a torque converter in an activated state, and operating an electric machine in a regenerative braking state. A state of the powertrain related to engine speed is monitored. The internal combustion engine is commanded to transition from the cylinder deactivation state to an all-cylinder state and the electric machine operates in the regenerative braking state including ramping down magnitude of regenerative braking torque when the engine speed is less than a first threshold speed. The torque converter clutch is commanded to a released state when the engine speed is less than a second threshold speed, with the first threshold speed being greater than the second threshold speed.
