1. A method of increasing mileage efficiency of a vehicle, the method comprising:
- acquiring an input control signal from an input control mechanism of the vehicle, the input control signal indicative of a position of an accelerator pedal of the vehicle;
determining a probability value that the input control signal includes a portion attributable to an unintentional force applied to the input control mechanism;
acquiring one or more different types of detected vehicular force signals from one or more force detection sensors;
determining a vector value based on the one or more different types of detected vehicular force signals;
determining a movement vector as a difference between the vector value and a baseline vector value;
adjusting the probability value based on the movement vector;
adjusting the input control signal according to the probability value to reduce the portion of the input control signal that is attributable to the unintentional force detected by the one or more force detection sensors; and
transmitting the adjusted input control signal to an output receiving unit for increasing mileage the vehicle.

Abstract
An input control signal is adjusted to account for a portion of the input control signal that may be attributable to unintended forces. Such unintended forces may include, but are not limited to, one or more of operator initiated unintended forces, vehicle-generated unintended forces, and extra-vehicular unintended forces. The amount by which the input control signal is adjusted correlates to a determined probability. The probability is an indicator as to how likely the input control value is affected by unintended forces.
