1. A method of estimating a trajectory of a vehicle having an Electronic Stability Program (ESP), the method comprising the steps of:

  • obtaining sensor data pertaining to dynamics of the vehicle;

    compensating for sensor drift using drift estimates calculated by the ESP; and

    calculating an estimate of the trajectory of the vehicle using the sensor data as compensated for sensor drift, and vehicle dynamics parameters estimated by the ESP;

    wherein the steps of obtaining sensor data and calculating the estimate of the trajectory of the vehicle are performed independently of any external signal communication infrastructure-based trajectory estimation tools.
