New third generation chipsets have been designed by Israel-based Autotalks, a vehicle-to-everything (V2X) communication technology developer, to support all pending V2X requirements. These devices, already contracted for series production of a passenger car by a major automotive original equipment manufacturer, are reportedly the first to support 5G-V2X for Day 2 scenarios.
Day 1 V2X offers life-saving situational awareness alerts. Day 2 V2X applications make use of sensor data shared by other vehicles and enable critical actions such as automatic braking. Braking the car requires functional safety certification, introduced for the first time in the third generation chipsets designed according to ISO26262 ASIL B.
The chipsets support concurrently full backward compatibility to any Day 1 vehicle, where each vehicle reports its own data, using either DSRC or LTE-V2X (C-V2X Rel. 14), and with any Day 2 technology, where the vehicle also reports all the information detected by its sensors, for sensor sharing or cooperative perception.
The TEKTON3 and SECTON3 chipsets will embed ultra-low-latency V2X Hardware Security Modules (eHSM) and hardware acceleration of line rate security verification. TEKTON3 also includes an optimized CPU scaled for Day 1 and Day 2 V2X stack execution.
First samples are expected to be available in early 2023, and the first cars equipped with the new chipsets are set to be available in 2025.
