1. A method for determining whether a panic braking maneuver has been initiated in a vehicle with a brake pedal, the method comprising the steps of:

  • receiving brake pedal travel data;

    receiving brake pedal force data;

    determining a rate of change of acceleration of the brake pedal from the brake pedal travel data via a processor;

    determining a rate of change of acceleration of force applied to the brake pedal from the brake pedal force data via the processor;

    comparing the rate of change of acceleration of the brake pedal with a first predetermined value and a third predetermined value via the processor;

    comparing the rate of change of acceleration of force applied to the brake pedal with a second predetermined value and a fourth predetermined value via the processor; and

    providing an indication that a panic braking maneuver has been initiated, if it is determined by the processor that;

    the rate of change of acceleration of the brake pedal is less than the first predetermined value;

    the rate of change of acceleration of force applied to the brake pedal is less than the second predetermined value;

    the rate of change of acceleration of the brake pedal was previously greater than the third predetermined value; and

    the rate of change of acceleration of force applied to the brake pedal was previously greater than the fourth predetermined value.
