The present invention provides time-of-flight-based security for multiple key fobs. A system for passive locking and unlocking a vehicle is described that includes a memory for storing executable instructions and a processor configured to execute the instructions to unlock the vehicle using a time of flight to transmit the trigger request between the vehicle and the first key fob. The processor receives, from a first key fob, a trigger request to unlock the vehicle, and determines, based key fob identifiers that identify the first key fob and a second key fob that is also near the vehicle, that the first and second key fobs are associated with a vehicle. The processor selects the first key fob based on a key fob characteristic. The processor evaluates the time of flight by using the first key fob, and unlocks the vehicle based on the time of flight satisfying a threshold for signal transmission flight time.
本公开提供了“多个钥匙扣的基于飞行时间的安全性”。描述了一种用于被动锁定和解锁车辆的系统,所述系统包括:存储器,其用于存储可执行指令;以及处理器,其被配置为执行所述指令以使用在所述车辆与第一钥匙扣之间传输触发请求的飞行时间来解锁所述车辆。所述处理器从第一钥匙扣接收解锁所述车辆的触发请求,并且基于识别所述第一钥匙扣和也位于所述车辆附近的第二钥匙扣的钥匙扣标识符来确定所述第一钥匙扣和所述第二钥匙扣与车辆相关联。所述处理器基于钥匙扣特性来选择所述第一钥匙扣。所述处理器使用所述第一钥匙扣来评估所述飞行时间,并且基于所述飞行时间满足信号传输飞行时间的阈值来解锁所述车辆。
