The US Army must update its vehicle fleet to be better equipped for potential future military conflicts in northern climates (US Army, 2017). This process involves considering manned, optionally manned, and unmanned vehicles as viable options in the future. Optionally manned and unmanned vehicles in the armed forces have substantial benefits because they can operate without direct driver input or are able to perform missions deemed too dangerous for troops. Optionally manned vehicles allow the driver to shift some, or all, focus away from the task of driving the vehicle. In some cases, these autonomous vehicles may perform better than a human driver by rapidly sensing and reacting to terrain changes. Onboard sensing and decision making are equally applicable to both fully autonomous and teleoperated vehicles. This work will focus on the terrain sensing, waypoint navigation, and teleoperation potential of an optionally manned or unmanned vehicle. Results from a vehicle demonstration on two different terrain conditions will provide the basis for additional terrain sensing and autonomous vehicle development work in the coming year.

美国陆军必须更新其车队，以更好地应对未来北方气候下潜在的军事冲突（美国陆军，2017 年）。这个过程涉及考虑有人驾驶、可选有人驾驶和无人驾驶车辆作为未来可行的选择。武装部队中可选的有人驾驶和无人驾驶车辆具有很大的好处，因为它们可以在没有驾驶员直接输入的情况下运行，或者能够执行对部队来说太危险的任务。可选的有人驾驶车辆允许驾驶员将部分或全部注意力从驾驶车辆的任务转移开。在某些情况下，这些自动驾驶汽车通过快速感知地形变化并做出反应，可能比人类驾驶员表现得更好。车载传感和决策同样适用于全自动和遥控车辆。这项工作将侧重于可选有人或无人驾驶车辆的地形传感、航点导航和遥操作潜力。在两种不同地形条件下进行的车辆演示的结果将为来年额外的地形传感和自动驾驶汽车开发工作提供基础。
