  • Patent number: 11560823
    Abstract: Methods and systems are provided for regenerating a particulate filter positioned in an exhaust system of an engine of a vehicle. In one example, a method comprises obtaining a first air flow in an intake of the engine and obtaining a second air flow in the intake of the engine, where regeneration of the particulate filter is conducted in response to the first air flow differing from the second air flow by at least a threshold amount, where the first air flow and the second air flow comprise air flow routed from the exhaust system to the intake of the engine. In this way, the particulate filter may be regenerated under conditions where a loading state of the particulate filter is not known.

    Abstract: An energy management control module is configured for communication with the vehicle controller. The energy management control module is configured to generate generator command data for the generator in a power command mode. In one embodiment, the energy management control module supports a first mode and a second mode. A first mode comprises the power command mode and a stored power extraction mode that are mutually exclusive modes for any sampling interval. In the power command mode of the first mode, the energy management controller is configured to generate generator command data for the generator based on a commanded motor torque and an energy storage power command (e.g., SOC command data) if the primary rotational energy of the internal combustion engine meets or exceeds the total vehicle load for a sampling interval.

  • Patent number: 11535237
    Abstract: An electric device control method controls an electric device that includes an internal combustion engine, a first electric motor that receives a driving force of the internal combustion engine to carry out power generation, and a second electric motor connected to a drive shaft. The method sets a rotational speed of the internal combustion engine to increase as a vehicle speed of the vehicle increases while the power generation is carried out by the first electric motor. Where the driving force required by the second electric motor becomes zero or negative while the first electric motor is carrying out power generation by the driving force of the internal combustion engine, the internal combustion engine is stopped where the vehicle speed is greater than or equal to a first threshold value, and the power generation is continued where the vehicle speed is less than the first threshold value.

  • Patent number: 11480421
    Abstract: An electric powertrain includes a sensor-controller interface, an inverter-controller electrically connected to the battery pack, and an electric machine connected to the inverter-controller and having a rotor with an angular position. The rotor powers a driven load at a torque and/or speed level controlled by the inverter-controller in response to position signals indicative of the angular position. A rotary position sensor is operatively connected to the rotor to generate and output the position signals. The sensor derives the position signals from unmodulated sine and cosine signals, and communicates the position signals and a binary sensor state of health (SOH) to the inverter-controller over the interface. The inverter-controller also decodes the position signals and the binary sensor SOH to generate decoded control data, and controls the torque and/or speed level using the decoded control data.

  • Patent number: 11465604
    Abstract: In a vehicle control method, when drive force which a second electric motor is requested to output increases in a state where an internal combustion engine is stopped, drive force which the second electric motor outputs by using electric power supplied by a battery is limited to a lower level than maximum drive force determined from electric power which can be supplied by the battery to drive an electric-powered vehicle. Then, the drive force which the second electric motor outputs by using the electric power supplied by the battery is increased over time in a period from when the second electric motor outputs the drive force limited to the lower level to when the internal combustion engine is fired up and a first electric motor starts power generation.

    Abstract: A system for controlling charging of a battery in a hybrid-electric vehicle. The system is configured to estimate a total vehicle power requirement and an available internal combustion engine power provided by the engine in each gear of a transmission system of the vehicle. The system may then determine a highest gear of the transmission system that has an estimated available power at least equal to the estimated total vehicle power requirement. The system may then, responsive to a state of charge of the battery falling below a predetermined low-charge threshold, and if the transmission system is not currently in the highest gear that has an estimated available power at least equal to the estimated total power requirement, control operation of the vehicle to shift the transmission system to the highest gear that has an estimated available power at least equal to the estimated total power requirement.
