CKSRI Seminar Series 2023 "Aggressive Maneuver of an Autonomous Driving Car"





Thank you to everyone who joined us today at CKSRI Seminar!


We are honoured to have Prof. Yilin Mo, Associate Professor in the Department of Automation, Tsinghua University, as our distinguished speaker.


Abstract: Conventional planning and control of autonomous vehicle adopts a kinematic model of the car. Although this model is sufficient for regular driving conditions, it does not consider the slip between the tires and the road, and hence cannot be applied to low friction cases, such as driving on ice or other slippery surfaces, or when driving the car close to or beyond its friction limit. In this talk we consider the problem of planning and control for an autonomous vehicle to perform an aggressive maneuver called drifting, which is characterized by a large side slip angle. We first propose an adaptive controller to control a circular drift motion, that can tolerate the change of the friction coefficient. For more complex motions, a high-level MPC-inspired reinforcement learning based planner, together with a low-level INDI (incremental nonlinear dynamic inversion) controller is proposed. Simulation and real world experiment on a 1:10 vehicle are provided to demonstrate the effectiveness of the proposed strategy.
