Driver-based control system and method to improve fuel economy
First Claim
1. An active driver control system for a vehicle, comprising:
- a driver command interpreter coupled to a plurality of driver inputs; and
an active driver command manager receiving a plurality of inputs including acceleration and deceleration commands from the driver command interpreter and vehicle data corresponding to a plurality of operating parameters, the active driver command manager using the vehicle data to actively attenuate the acceleration and deceleration commands to conform acceleration and deceleration of the vehicle to achieve predetermined consumption targets and to reduce undesired frequency content;
wherein the active driver command manager attenuates driver controlled input from at least an accelerator pedal sensor and a brake pedal sensor; and
wherein a driver index quantifier calculates a driving index based on a comparison of driver targets to a quantification of driver control ability.

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. 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.
