V2X Integration

Over the years, Commsignia has gained a tremendous amount of experience in deploying and operating V2X onboard units.

  • Participating in deployment and OEM/Tier-1 trials
  • Fusion algorithms for ADAS systems
  • Day1 / Day2 applications
  • Sensor data integration

Complete Ecosystem with V2X Software

The Commsignia V2X Software Stack is a flexible embedded solution developed based on the specification of the ISO / ETSI / IEEE / SAE / C2C-CC communication architecture. The software stack provides a modular framework and small footprint for various resource-constrained target platforms, supporting Linux and RTOS operating systems.

Use Cases
Electronic Emergency Brake Light

The vehicle broadcasts an emergency brake event to nearby vehicles. The recipient vehicles determine the relevance of the information and warn the drivers about the event if appropriate.
Stationary vehicle warning

Informs road users about a stationary vehicle before they could actually see it to eliminate the risk of accidents.
Forward Collision Warning

Warns drivers about an impending rear-end collision with another vehicle in the traffic in the same lane.
Intersection Movement Assist

A vehicle-to-vehicle (V2V) application that warns the driver when it’s not safe to enter an intersection.
Emergency vehicle

Prepares the driver to give way to an approaching emergency vehicle before its presence could be realized.
Lane Change Assist

Assists a vehicle in changing lanes, and sends a warning signal to the driver if the intended lane destination is occupied by other vehicles.
