    摘要： Alcohol concentration level of flex fuel is estimated based upon in-cylinder ionization signals. The in-cylinder ionization signals are integrated and the rotational completion point of a chosen percentage of the integration total is identified as the integration location for the operating conditions under observation. The calculated integration location correlates with alcohol concentration level of flex fuel, and the integration calculations provide a basis for a virtual flex fuel sensor that provides calculated estimates of alcohol concentration rather than direct sensing using an expensive physical flex fuel sensor.

    摘要： The technology described herein provides an active driver control system. Additionally, in various example embodiments, this technology provides methods for optimizing fuel economy (or energy consumption) through active compensation of driver controlled inputs. The active compensation functionality is used to moderate ‘sweet spot’ vehicle response with driver desired performance. In particular, the active compensation functionality can be used to smooth the vehicle response and attenuate undesired frequency content from the driver input. One of the benefits to this technology is that it assists all drivers in achieving better fuel economy in real world driving. Another benefit is that active compensation of driver controlled inputs can mitigate some of the negative effects of more aggressive driving styles. In addition to active compensation functionality, the technology described herein is also capable of generating a Green Driver Index which is derived by quantifying the driver's control ability and normalizing the result against desired fuel economy and performance targets.
