1. A system for estimating a pitch state of a ground-traversing vehicle, the system comprising:

  • a tilt sensor connected to the vehicle producing a pitch signal representing an estimate of a pitch angle of the vehicle about an E-frame of reference;

    at least one inertial reference sensor connected to the vehicle producing an inertial orientation signal about a V-Frame of reference; and

    a state estimator module receiving the pitch signal and the inertial orientation signal and calculating a pitch state signal from the inertial orientation signal and the pitch signal;

    wherein the pitch state signal is provided to a control loop of the vehicle for dynamically maintaining stability of the vehicle.
