Wireless communication systems have considerably evolved over the last years and advanced technologies for improving vehicle safety and traffic efficiency are available. In particular WLAN-V2X and Cellular V2X considerably shorten, in comparison to conventional communication systems, the communication latency. While the project KOALA in the first phase of SPP1835 mainly focused on the reduction of the latency generated by the communication system as well as on modelling the latency, the follow-up project KOALA2 addresses how these low latency communication systems can be exploited for communication-based vehicle automation in a holistic approach. KOALA2 has three main objectives: (i) The exchange of sensor data among vehicles for cooperative perception can easily exceed the available data rate of the communication link. In contrast to previous approaches for data congestion control, KOALA2 studies adaptive schemes that dynamically adjust the generated object lists to match the instantaneous data rate, in consideration of the present driving situation. (ii) For scenario-based maneuver coordination among vehicles in cooperative use cases (such as lane change, platooning and emergency steering) the project develops design patterns for communication, in order to complement sensor-based maneuver planning by explicit communication. The state-of-the-art broadcast-based information dissemination is extended by communication in groups of vehicles, which exclusively encompasses the actors of the corresponding maneuver. The design patterns are used in a messaging framework that realizes a reliable communication for planning, execution and completion (or termination) of cooperative driving maneuvers. (iii) The developed techniques are prototypically implemented and experimentally validated. The project sustainably improves the cooperative perception as well as the cooperative maneuver and trajectory planning as key technologies for safety-relevant time critical use cases in cooperative automated driving.

无线通信系统在过去几年中已经有了相当大的发展，并且可以使用用于提高车辆安全性和交通效率的先进技术。特别地，与传统通信系统相比，WLAN-V2X和蜂窝V2X显著缩短了通信延迟。虽然SPP 1835第一阶段的项目KOALA主要关注减少通信系统产生的延迟以及延迟建模，但后续项目KOALA 2解决了如何以整体方法将这些低延迟通信系统用于基于通信的车辆自动化。KOALA 2有三个主要目标：（一）车辆之间的传感器数据交换合作感知很容易超过通信链路的可用数据速率。与以前的数据拥塞控制方法相比，KOALA 2研究了动态调整生成的对象列表以匹配瞬时数据速率的自适应方案，考虑到当前的驾驶情况。(ii)对于协作用例（如车道变换，排队和紧急转向）中车辆之间基于传感器的机动协调，该项目开发了通信设计模式，以通过显式通信补充基于传感器的机动规划。最先进的基于广播的信息传播通过车辆组中的通信来扩展，车辆组仅包括相应机动的参与者。设计模式中使用的消息传递框架，实现了一个可靠的通信规划，执行和完成（或终止）的合作驾驶演习。(iii)所开发的技术原型实现和实验验证。该项目可持续地改进了协同感知以及协同机动和轨迹规划，作为协同自动驾驶中安全相关的时间关键用例的关键技术。
