Radio frequency sensing in in-vehicle environment

Embodiments described herein address these and other issues by providing radio frequency (RF) sensing to determine the status of a driver or other occupant of the vehicle. The RF sensing may be provided by an existing radio of the vehicle, such as a Wi-Fi transceiver, and thus RF sensing functionality may be provided to the vehicle with little increased cost. RF sensing may be utilized to implement security features, such as detecting unattended children or pets in a vehicle, detecting driver alertness, and the like. 本文描述的实施例通过提供射频(RF)感测以确定车辆的驾驶员或其他乘员的状态来解决这些和其他问题。RF感测可以由车辆的现有无线电装置(诸如Wi-Fi收发器)提供，并且因此可以以几乎不增加的成本向车辆提供RF感测功能。可以利用RF感测来实施安全特征，诸如检测车辆中的无人照管的儿童或宠物、检测驾驶员警觉性等。
