1. A system for dynamically estimating longitudinal and lateral velocities of a vehicle comprising:

  • a vehicle sensor producing a signal indicative of a vehicle state; and

    a processor communicating with said vehicle sensor and configured to receive said signal, said processor further configured to;

    calculate an approximated velocity of the vehicle;

    determine a noise covariance associated with said signal and said approximated velocity; and

    estimate the velocity of said vehicle using said signal, said approximated velocity and said noise covariance.
