  • Patent number: 8311722
    Abstract: 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.
