Path Planning based on Clothoid for Autonomous Valet Parking

WebThe results in Arechavaleta et al. (2008), have shown that the cost function to be minimized is a variation (time derivative) of the path curvature which implies that clothoid arcs are a good approximation of a walking path. This conclusion was adopted and clothoid arcs have been chosen for path shape in our path planning algorithm.
