Collision Avoidance Smoothing: A Viscous-Elastic Model

Development of a Collision Avoidance Algorithm Using Elastic Band Theory

This paper presents a new Collision Avoidance (CA) Algorithm which uses Elastic Band Theory. Researchers tried to develop warning systems to avoid collisions which warn drivers of possible collision risk with audio and or visual signs. However, these systems are not sufficient for avoidance of a collision in situations where the driver gives no response to the warnings. CA System is a kind of A...

Planning of Optimal Collision Avoidance Trajectories with Timed Elastic Bands

This paper is concerned with the planning of optimal trajectories for vehicle collision avoidance with a Timed Elastic Band (TEB) framework. The avoidance trajectory is represented by a TEB which is optimized with respect to multiple partially conflicting objectives. The resulting trajectory constitutes the optimal compromise between a mere braking and a lane change maneuver that avoids the col...

Path Planning for Automotive Collision Avoidance Based on Elastic Bands

Collision-free path planning will be an essential feature of future automotive collision avoidance systems (CAS). One of the most promising approaches uses so-called elastic bands in generating emergency trajectories. For the automotive application of this approach, moving obstacles and the borders of the road are modeled by virtual potential fields. To find solutions even in complex driving si...

Communication in distributed model predictive collision avoidance

This paper presents a model predictive approach for collision avoidance of car-like robots. An optimal problem is formulated in terms of cost minimization under constraints. Information on each robot can be incorporated online in the nonlinear model predictive framework and kinematic constraints are treated by Karush-Kuhn-Tucker(KKT) condition. For distributed collision avoidance of multiple ro...
