Abstract
Disclosed herein are methods and systems for efficient optimal control with dynamic modeling for an autonomous vehicle (AV). The method may include acquiring vehicle status information for the AV, determining a longitudinal velocity of the AV, determining a driving style factor, wherein the driving style factor is dependent on at least road scenarios, obtaining an optimal control factor from a look-up table (LUT) using the determined longitudinal velocity and the determined driving style factor and providing an updated control command (such as a steering command) based on the obtained optimal control factor. The driving style factor may be determined from at least vehicle status, desired trajectory, current linear velocity and like parameters and ranges between a gentle driving mode and an aggressive driving mode.
