确保自主汽车射频电路失效时的安全

　　确保自主汽车射频链路失效时的安全

　　主要公司的口袋里正在积极追求自主车辆和机器，但在平衡的生命和法律责任，设计师的压力下，以确保导航性能最佳。这意味着传感器备份和冗余。

　　本文介绍了无线导航如GPS和Wi-Fi的情况下，可以呈现无法操作。然后，它勾勒出一个设计和实施方法，使用替代和互补的辅助工具和传感器的自主车辆和机器人。特别是，它将指向选项，帮助补偿的位置和状态的RF连接的变幻莫测。

　　Tech adoption’s un-sensed side effects

　　From delivery services for products and pizza， to Johnny Cabs from ‘Total Recall”， both car makers， retailers， and service corporations （like Uber） are putting a lot of resources into robots and vehicles that are location aware and adaptive to their immediate environments.

　　Meantime， the federal government has given the green light for states to regulate autonomous vehicles， and we are living in an evolving time with this new technology just beginning to be integrated into the transportation networks. As design engineers， we need to make sure this is done safely， especially given how lives and liability are in play.

　　While navigational aids like GPS have become almost indispensible， it seems that the more we rely on technology， the less able we are to perform even the mundane tasks that our devices perform. It’s getting to the point where people rely on GPS to navigate places they traverse on a daily basis. This can be troubling， especially as we realize that our technologies can fail. And when they do， we risk helplessness; or worse.

　　For example， as GPS systems strive to achieve finer resolution to ensure accuracy and reliability， there will be times when loss of signals could lead to catastrophic effects without some form of system backup. Anyone using a GPS knows what happens to a GPS signal upon entering a long tunnel.
