高通量车规级蜂窝直连侧链 (PC5) 系统
VehiclesLink 彻底摆脱对地面蜂窝基站中继的依赖,构建点对点直连车车无线通信链路。依托 3GPP Release 16 5G NR 侧链标准,在 5.9 GHz 智能交通专用频段上运行,为全自主高速公路车队编组提供低时延骨干信道。
Sidelink Coordinator Zonal Architecture
Central Controller: Sidelink Coordinator — 3GPP Rel-16 NR PC5 Modem
Zonal Control Units & TSN Ring
- Autonomous Mode 2 Resource Sensing Engine
- Cooperative Adaptive Cruise (CACC) Loop
- Unicast / Groupcast Session Manager
- Zonal Brake-by-Wire Hardware Link
- Direct RF Antenna Switching Array
彻底剔除传统蜂窝基站中转时延,实现毫秒级车队编组跟车控制闭环
以 100 km/h 车速、仅 3 米车距疾驰的自动驾驶卡车编组,绝对无法容忍经由云端蜂窝网络往返长达 60 毫秒的绕行延迟。哪怕仅仅一帧制动报文延迟,都会瞬间导致灾难性的多车连环追尾。VehiclesLink 借助直连 PC5 侧链接口,将制动执行指令在 4 毫秒以内直接送达。
