About the Edition

There are two goals for autonomous vehicle navigation planning: shortest path and safe path. These goals are often in conflict; path safety is more important. Safety of the autonomous vehicle"s navigation is determined by the clearances between the vehicle and obstacles. Because a Voronoi boundary is the set of points locally maximizing the clearance from obstacles, safety is maximized on it. Therefore Voronoi Diagrams are suitable for motion planning of autonomous vehicles. We use the derivative of curvature k of the vehicle motion (dk/ds) as the only control variable for the vehicle where s is the length along the vehicle trajectory. Previous motion planning of the autonomous mobile robot Yamabico-11 at Naval Postgraduate School used a path tracking method. Before the mission began the vehicle was given a track to follow; motion planning consisted of calculating the point on the track closest to the vehicle and calculating dk/ ds then steering the vehicle to get onto track. We propose a method of planning safe motions of the vehicle to calculate optimal dk/ds at each point directly from the information of the world without calculating the track to follow. This safe navigation algorithm is fundamentally different from the path tracking using a path specification. Additionally motion planning is simpler and faster than the path tracking method. The effectiveness of this steering function for vehicle motion control is demonstrated by algorithmic simulation and by use on the autonomous mobile robot Yamabico 11 at the Naval Postgraduate School.

The race is organised by the Pentagon's defence agency to push research into autonomous vehicles for the US military. This year it has doubled the prize fund for the challenge. The vehicles have been kitted out and modified with GPS (global positioning satellite), cameras, infrared sensors, computing equipment, and lasers to guide them across.   The upper bound is the longest distance that the autonomous vehicle can fall behind the lead. This is derived from assuming a distance that would prevent safe cut-ins from adjacent lanes and is kept at m/m/s(4 ft/MPH). The spacing function comes from results presented in the U.S. Department of Transport study on traffic flow theory. The Cited by: 1.

By immersing himself in the autonomous vehicle world, he has accumulated a wealth of knowledge around the technology, issues and potential solutions that will make self-driving vehicles a reality. His passion for the safe deployment of autonomous vehicles has made him a popular speaker at automotive conferences worldwide.

This paper presents models of path and control planning for the parking, docking, and movement of autonomous vehicles at low speeds, considering space constraints. Given the low speed of motion, and in order to test and approve the proposed algorithms, vehicle kinematic models are used. Recent works on the development of parking algorithms for autonomous vehicles are reviewed.

Not having to stop for recharging will make EVs truly autonomous, and, because the vehicles can thus remain in service for more hours, fewer vehicles will be needed to meet passenger demand. Furthermore, EVs with in-motion (dynamic) wireless charging can have much smaller batteries, an option that can reduce their cost and accelerate adoption.

Autonomous vehicles will need a platform to direct them to pick up riders and to verify who is entering and exiting the vehicle. They will need extensive fleet management and predictive maintenance platforms to understand potential wear issues, automate towing, recharging, and cleaning, detect left items etc.

Autonomous cars, or cars that run without a human driver, have been in development for over the past few decades, starting from the late 70’s and extending towards the present date and even beyond.

During the early stages, the autonomous vehicles were slow in speed and even in reaction time. Vehicles that can be considered autonomous must be able to make decisions and react to events without direct intervention by humans.

Although some UAVs are able to perform increasingly complex autonomous manoeuvres, most UAVs are not fully autonomous; instead, they are mostly operated remotely by humans.
