Navigation Negotiations for Autonomous Vehicles

When on the road, today's human drivers can often experience confusion and frustration from inefficient traffic flow, especially because the actions of other drivers are difficult to anticipate. Autonomous vehicles (an imminent possibility with current research) can communicate among vehicles within close proximity, and share information such as intended path to destination. (Figure 1) This alleviates inefficiencies and unpredictability, while also catering to the passenger's level of urgency by negotiating priority among the nearby vehicles.

Although there is no art blocking this invention, following are related ideas:


• Integrated Path Planning and Dynamic Steering Control for Autonomous Vehicles. [1] This paper deals with combining algorithms for path planning and dynamic steering control in order to communicate real time feedback to the autonomous vehicles. It shows that the travel paths for autonomous vehicles can be done to our invention's advantage. However, it does not teach the methods of the disclosed invention.


• Real-Time Coordination of Autonomous Vehicles. [2] This paper demonstrates that autonomous vehicles can be coordinated based on safety constraints. It further discusses a message communication model in which to notify vehicles within proximity of the coordination mechanisms. The disclosed invention could probably use a coordination method like this (which is one of many) as enabling art. It does not teach any methods to allow autonomous vehicles to negotiate priority and arrival to their destination.


• Vehicles That Talk to Each Other Know What Lanes They are in. [3] This reference addresses lane detection and its accuracy over a Global Positioning System (GPS). In some cases, it may detect which vehicle may switch lanes. It does not teach any methods to allow autonomous vehicles to negotiate priority and arrival to their destination.

The core idea of this navigation system is to have autonomous vehicles communicate their anticipated paths with each other so that they are routed in the most efficient way.

When autonomous cars can communicate their intents to each other, the optimal path can be determined among the vehicles on the road, thus moving traffic along more efficiently (e.g., situations in which traffic must be cleared for emergency vehicles to pass first). Additionally, drivers may bid and attach a price/urgency level to arrive at their destination on time.
