Autonomous vehicles (AVs) promise a future with safer, cleaner, more efficient, and more reliable transportation. However, the current approach to autonomy has focused on building small, disparate intelligences that are closed off to the rest of the world. Vehicle connectivity has been proposed as a solution, relying on a vision of the future where a mix of connected autonomous and human–driven vehicles populate the road. Developed by the U.S. Department of Transportation Federal Highway Administration (FHWA) as a reusable, extensible platform for controlling connected autonomous vehicles (CAVs), the CARMA Platform, is one of the technologies enabling this connected future. Nevertheless, the adoption of CARMA has been slow, with one contributing factor being the limited, expensive, and relatively old vehicle configurations that are officially supported. To alleviate this problem, we propose the eXperimental vehicle platform for Connected Autonomy Research (X-CAR). By implementing the CARMA Platform on more-affordable, high-quality hardware, X-CAR aims to increase the versatility of the FHWA platform and facilitate its adoption for research and development into connected driving automation.

X-CAR：用于互联自主研究的实验车辆平台

自动驾驶汽车 (AV) 有望在未来提供更安全、更清洁、更高效和更可靠的交通。然而，当前的自治方法侧重于构建小型的、完全不同的智能，这些智能与世界其他地方隔绝。车辆连接已被提议作为一种解决方案，其依赖于未来的愿景，即连接的自动驾驶和人力驾驶车辆混合出现在道路上。CARMA 平台由美国交通部联邦公路管理局 (FHWA) 开发，作为控制联网自动驾驶汽车 (CAV) 的可重复使用、可扩展平台，是实现这一互联未来的技术之一。然而，CARMA 的采用一直很缓慢，其中一个因素是有限、昂贵、以及官方支持的相对较旧的车辆配置。为了缓解这个问题，我们提出了用于互联自主研究 (X-CAR) 的实验车辆平台。通过在更实惠、高质量的硬件上实施 CARMA 平台，X-CAR 旨在提高 FHWA 平台的多功能性，并促进其在互联驾驶自动化的研发中的采用。
