Automatic air collision avoidance system
Proceedings of the 41st SICE Annual Conference. SICE 2002., 2003This paper presents an algorithm for an automatic air collision avoidance system being developed by the US Air Force and its Swedish counter part, Forsvaret Materielverk (FMV). The algorithm uses optimal coordinated escape maneuvers to avoid mid-air collision, while satisfying the imposed system requirements.

On Automatic Collision Avoidance Systems
SAE Technical Paper Series, 2005<div class="htmlview paragraph">In future automotive collision avoidance systems (CAS) collision-free path planning will be required. For this reason, two possible path planning techniques are compared. The first method is based on the mathematical theory of differential games, the second method focuses on so-called elastic bands.

AUTOMATIC PARKING WITH COLLISION AVOIDANCE
Applied Computational Intelligence, 2004Automatic parking of a car-like robot in the presence of a priori unknown obstacles is the topic of the paper. This problem is solved by means of a bio-inspired approach in which the robot controller does not need to know the car kinematics and dynamics, neither does it call for a priori knowledge of the environment map.

Collision avoidance with automatic braking and swerving
IFAC Proceedings Volumes, 2014Abstract To avoid collisions in longitudinal direction emergency braking is suitable in many situations. However for higher velocites, an evasive maneuver is better because it can be applied later than the braking maneuver if there is enough free space.

Safety Control of Automatic Excavator for Swing Collision Avoidance
2018 15th International Conference on Ubiquitous Robots (UR), 2018The importance of safety for automated construction machinery is continuously increasing. Especially, excavators are frequently exposed to fatal accident because it works closely with human workers. Distance - based safety technique lacks the analysis of the braking ability of the excavator's hydraulic system and the dynamic motion of the object.

Automatic collision avoidance based on supervised predictive controllers
Control Engineering Practice, 1996Abstract In general, adaptive predictive control techniques have been applied to systems presenting slow dynamics or large delays. In cases where fast maneuvers are considered, their parameters estimation function and their control computation function must be enhanced to cope with these transient situations.

An optimal control problem for automatic air collision avoidance
42nd IEEE International Conference on Decision and Control (IEEE Cat. No.03CH37475), 2004In this paper, we discuss an automatic air collision avoidance problem from an optimal control theory standpoint. The objective is to find the combination of escape maneuvers between two aircraft that attains the largest minimum separation distance among all the possible choices of escape maneuvers. To achieve this objective, a terminal optimal control

Automatic Collision Avoidance and Navigation
2008The main goal of this paper is to permit the growth of air traffic, whilst maintaining or increasing flight safety levels through automation. This should assist pilots and air traffic controllers and increase aircraft autonomy. MAGENTA is a PhD thesis, providing a framework for developing automatic learning tools.

An automatic multi-objective collision avoiding approach
2016 IEEE 11th Conference on Industrial Electronics and Applications (ICIEA), 2016This paper studies challenge of multi-objective collision avoidance under complicated water environment. To tackle this challenge, this paper exploits velocity obstacle method, along with maneuvering characteristics of ships, to develop a ship collision avoidance approach.

AUTOMATIC STEERING AND BRAKING FOR A COLLISION AVOIDING VEHICLE
IFAC Proceedings Volumes, 2006Abstract A collision avoiding vehicle driver assistance system is developed using braking, steering or a combination of steering and braking. To guide a vehicle on a desired trajectory for emergency steering, two feedback control approaches are presented. The combined steering and braking intervention requires a further control system. The estimation
