Adaptive collision avoidance motion planning strategy for autonomous vehicle

What is it about?

Collision avoidance systems are one of the advanced active safety technologies aimed to improve vehicle safety and reduce human error for collision prevention by assisting the driver during critical situations. In the collision avoidance system, motion planning is developed for the purpose of preparing the reference trajectory with regard to obstacles, road edges, and traffic rules while taking into consideration the vehicle constraints to perform an autonomous reaction. This work presents an adaptive motion planning strategy for autonomous vehicle collision avoidance systems to be associated with the variation of collision speed region and obstacle position during avoidance maneuver.

Why is it important?

The proposed motion planning strategy with an adaptive multi-speed scheduler resulted to provide the control command that managed to avoid collision by evasive maneuver without lane departure when adapting to variation in the vehicle speeds with different obstacle positions.
