One global V2X solution: DSRC and C-V2X

Why develop a solution per geography?

Divergence of V2X standards requires a global solution

Most car manufacturers announced their intentions to equip vehicles with V2X. V2X diverged into two different standards, DSRC, with a large install base in Europe, and C-V2X, selected in China and US, with fundamentally different architectures. This makes it difficult for OEMs to harmonize a single global solution.

Autotalks can speak all languages: DSRC or C-V2X

At Autotalks, we decided to resolve the issue of the two competing V2X standards and design one global solution. By equipping our mass-market ready 2nd generation, automotive qualified chipsets with C-V2X, in addition to their native support of DSRC, Autotalks created the world’s first dual mode chipset. With Autotalks’ Global V2X solution, OEMs no longer need to develop a solution per geography.

Autotalks global V2X chipset: automotive qualified with global security

Autotalks delivers dual-mode (DSRC and C-V2X) functionality on its automotive qualified AEC-Q100 grade 2 chipsets. All global security standards (US, China and Germany) are supported.

The solution is not dependent on any cellular network
Autotalks global V2X solution does not need a cellular connect to work. There are many clear advantages to the separation from the cellular network both to the OEM and the consumer.

Benefits to OEMs:

  • Lowest development cost: Cost can be lower with only one global V2X platform and architecture
  • No supply limitation: A different cellular modem can be used in different countries without redesigning V2X
  • Security certification feasibility: Clear isolation of V2X security assets
  • Stable V2X design: Every new cellular modem version, per geography and Telematics class (low / mid / high), would require an unnecessary V2X redesign
  • Short boot time: Should be lower than 2 seconds, cellular modem is likely to exceed this target

Benefits to the consumer:

  • Separation between Safety Messages and Infotainment: In order to ensure that V2X isn’t exposed to network attacks, V2X must be separated from the cellular network
  • Safe and Secure: Without separation from the cellular network, there is no assurance that cryptographic V2X assets are accessed only by allowed processes
