Abstract: Methods and system are disclosed for vehicle power control. a first high voltage, HV, demand signal is received from a HV device and a first low voltage, LV, demand signal is received from a LV system of the vehicle. The first HV demand signal can be modified based on the first LV demand signal. An input HV supply is received from an e-machine based on the first LV demand signal and modified HV demand signal. An output LV supply is provided from a first DCDC converter to the LV system of the vehicle and an output HV supply is provided from a second DCDC converter to the HV device.

Abstract: A vehicle charging system includes a vehicle charge port having a first connector with one or more first magnets and a plurality of first terminals arranged in a first array. A charge station for the vehicle includes a support and a second connector attached to the support by an articulating mechanism that permits movement of the second connector relative to the support. The second connector has one or more second magnets and a plurality of second terminals arranged in a second array that matches the first array so that the first terminals are connectable to the second terminals when the first and second connectors aligned. The first and second magnets are arranged to move the second terminals, via the articulating mechanism, into alignment with first terminals when the first and second connectors are within a magnetic-coupling range.

Abstract: Methods and systems are provided for controlling particulate filter temperature during non-combustion conditions. In one example, a method for an engine includes responsive to a particulate filter temperature above a threshold temperature and while operating the engine with deceleration fuel shut-off (DFSO), fully closing a throttle valve configured to regulate flow of intake air to the engine, and responsive to intake manifold pressure dropping below a threshold pressure while the throttle valve is fully closed, adjusting a position of the throttle valve based on the particulate filter temperature.

Abstract: Methods and systems are provided for expediting exhaust particulate filter regeneration. In one example, an engine controller may generate an exotherm at the filter by operating engine cylinders with air-fuel imbalance while using electric assist to a turbocharger to meet a torque demand and raise an intake airflow to enhance the effect of the exotherm. Once heated, the filter may be regenerated by flowing extra air to the exhaust via an air pump and injecting extra fuel to an exhaust passage via an exhaust injector.

Abstract: Methods and systems are provided for adjusting engine compression ratio (CR) and spark timing to attain particulate filter (PF) regeneration temperature. In one example, a method may include, in response to PF load reaching a threshold and PF temperature being lower than the PF regeneration temperature, lowering the CR and then selectively adjusting spark timing based on an estimated residual gas fraction (RGF) at the lower CR.
