摘要： Methods and systems are provided to control a regenerative braking system comprising a battery, e.g., of a vehicle. The regenerative braking system harvests energy from a braking event. The energy can be stored in the battery, used to power a plurality of devices in the vehicle, or the battery can be preconditioned to provide more capacity to account for a braking event. The vehicle system may comprise one or more electrical loads configured to use power from the battery. The method comprises detecting a regenerative braking event of the vehicle and activating a first electrical load to consume the energy from the regenerative braking event.

摘要： Methods and systems are provided for partially regenerating a lean Nox trap in response to an engine shutdown request. In one example, an engine shutdown is delayed so that a low-temperature storing region of the lean Nox trap is regenerated without regenerating a high-temperature storing region of the lean Nox trap.

摘要： Methods and systems are provided for an exhaust aftertreatment arrangement. In one example, a system includes a LNT upstream of an SCR with an oxygen storage component arranged therebetween, and where a rich operation of an engine is limited based on an oxygen load of the oxygen storage component when an exhaust gas temperature is higher than a limit temperature.

摘要： Methods and systems are provided for partially regenerating a lean NOx trap in response to an engine shutdown request. In one example, an engine shutdown is delayed so that a low-temperature storing region of the lean NOx trap is regenerated without regenerating a high-temperature storing region of the lean NOx trap. A battery charge is replenished during the shutdown, wherein the charge may be consumed during a subsequent engine operation.

摘要： Methods and systems are provided for regenerating a particulate filter in an engine exhaust, where burning of soot is initiated by introducing additional oxygen into the exhaust gas upstream of the particulate filter where an exhaust temperature exceeds a threshold, a soot burn rate controlled by adjusting pulsing of the additional oxygen. Further, the pulsing of the additional oxygen is introduced via a high-pressure EGR passage during boosted engine conditions.

摘要： 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.

摘要： Methods and systems are provided for an exhaust gas arrangement. In one example, a system includes a lean-NOx trap arranged upstream of a selective-catalytic reduction device with an air supply device positioned to inject air therebetween, wherein the air supply device is activated in response to an exhaust gas being rich and an exhaust gas temperature exceeding a limit temperature.

摘要： The present disclosure relates to an operating method for a motor vehicle having a hybrid drivetrain where in a demand check, at least one exhaust-gas after-treatment actual value, which characterizes a current exhaust-gas after-treatment actual state, is compared with an exhaust-gas after-treatment setpoint value, and if, in the event of a deviation of the exhaust-gas after-treatment actual value from the exhaust-gas after-treatment setpoint value, a demand for a measure is detected. The measure comprises supplying charge gas, which has recirculated exhaust gas, to the internal combustion engine during overrun operation. Also a capability check is carried out to detect conditions suitable for implementing the operating method.

摘要： Methods and systems are provided for regenerating an after-treatment system of a vehicle. A first operational parameter of a first component of the after-treatment system is monitored and a second operational parameter, different to the first operational parameter, of a second component of the after-treatment system is monitored. It is determined if the first operational parameter of the first component is outside a first threshold range and if the second operational parameter is approaching a second threshold and, in response to the first operational parameter being outside the first threshold range and the second operational parameter being within the second threshold range, a regeneration sequence of the after-treatment system configured to regenerate at least the first component of the after-treatment system is initiated.
