Abstract: Systems and methods of cooperative autonomous driving which maximize objectives of a global traffic environment are provided. In particular, a cooperative controller may control multiple connected vehicles within a traffic environment. In certain embodiments, the cooperative controller may assign each connected vehicle a traffic role, based in part on their situation within the traffic environment. In some embodiments, this traffic role may also be based on a “priority level” for the connected vehicle which corresponds to a desired travel time. Once traffic roles have been assigned, the cooperative controller may control each connected vehicle according to a driving policy associated with its assigned traffic role.

In an illustrative example, the DCCH may include a controller circuit and multiple independent reconfigurable connection ports (IRCPs). For example, the DCCH may be connected to multiple edge devices and controllers at the IRCPs. The edge devices and controllers may use different communication protocols.

Based on a second set of rules, for example, the control circuit may determine a communication protocol of the IRCP. Various embodiments may advantageously avoid human intervention in setting up each of the multiple IRCPs of the DCCH.
