  • Publication number: 20240190259
    Abstract: Methods, systems, and devices for electric machine torque adjustment based on waveform multiples are disclosed herein. One electric machine controller, arranged to direct pulsed operation of an electric machine, utilizes a pulse controller that calculates a first average measured torque from sensed torque values over a first time period and a second average measured torque from sensed torque values over a second time period, wherein the first and second time periods are different time periods.

  • Patent number: 11916498
    Abstract: Methods, systems, and devices for electric machine torque adjustment based on waveform integer multiples are disclosed herein. One electric machine controller arranged to direct pulsed operation of an electric machine includes utilizing a pulse controller that calculates an average torque based upon a time period that corresponds with an integer multiple of a waveform cycle of a pulse waveform.

  • Patent number: 10619584
    Abstract: Various methods and arrangements for improving fuel economy and noise, vibration, and harshness (NVH) in a skip fire controlled engine are described. An engine controller dynamically selects a gas spring type for a skipped firing opportunity. Determination of the skip/fire pattern and gas spring type may be made on a firing opportunity by firing opportunity basis.

  • Patent number: 8511281
    Abstract: A variety of methods and arrangements for controlling the operation of an internal combustion engine in a skip fire variable displacement mode are described. Generally, an engine is controlled to operate in a skip fire variable displacement mode. In the variable displacement mode, selected combustion events are skipped so that other working cycles can operate at better thermodynamic efficiency. More specifically, selected “skipped” working cycles are not fired while other “active” working cycles are fired. Typically, fuel is not delivered to the working chambers during skipped working cycles. In one aspect of the invention, a firing pattern is determined that is not fixed but the active working cycles are selected to favor the firing of working chambers that have recently been fired at least in part to reduce wall wetting losses.
