<p><span style="font-size:16px;">随着车辆网联产品的发展,数字钥匙作为传统汽车钥匙的颠覆者,为越来越多的年轻人所青睐。用使用频率非常高的手机替代传统的汽车钥匙,不仅能让用户轻松便捷地实现车辆的控制,解决找不到车钥匙的困扰,还能够借助数字钥匙的虚拟认证系统,实现汽车钥匙的隔空分享、车辆的个性化配置等互联场景。</span></p>
<p> </p>
<p><span style="font-size:16px;">目前数字钥匙产品技术仍以低功耗蓝牙(Bluetooth Low Energy)+NFC(Near Field Communication)为主。BLE通过RSSI信号强度判断用户离车的远近,实现PEPS无钥匙进入和启动的功能,其显著优势在于性价比。但BLE的抗干扰性差,容易受到身体遮挡、天气等外部环境影响,在数字钥匙这种与用户体验强关联的产品及应用上,逐渐暴露其自身的不足。UWB是 ultra wideband 的缩写,简称超宽带数字钥匙系统,相较于BLE,其安全性更高,作用范围更强,能够准确到厘米级定位,以此可以延伸出更多的智能化应用场景,例如单门迎宾自动解锁,手机遗留车内提醒等。</span></p>
