METHOD AND SYSTEM OF QUANTIFYING AND MANAGING STEERING COMMAND-RESPONSE LATENCY FOR AN AUTONOMOUS VEHICLE

A method and system of quantifying and managing steering command-response latency for an autonomous vehicle. The system enables the method to determine a lag time between issuing a control command and achieving a commanded angle for a plurality of predetermined vehicle velocities. A predetermined number of lag times are averaged for each of the plurality of predetermined vehicle velocities. The average lag times are weighted in which the more current determined lag times have a higher weight than a less current determined lag time. The averaged time lag is used to improve the response of the vehicle and to detect a health issue in the steering system of the vehicle.
