V2X Communication for Autonomous Driving

The emergence of DSRC-based V2V and V2I communications increases the acceptance of autonomous cars

Slide background

The emergence of DSRC-based Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications increases the level of certainty regarding a vehicle’s surroundings, and serves as an enabler for autonomous driving.

DSRC-based V2X is essential for safe and efficient Autonomous Driving:

 

Accurate vehicle information: Vehicle sensors are estimating vehicle data. Only DSRC can provide

accurate speed, heading, status of brake pedal, and more.

Sensing of obstructed objects: V2X communication alerts the autonomous vehicle about objects

it cannot directly see (non-line-of-sight), which is vital for safety and facilitates better decisions

by the robot car.

Works in any environmental conditions: While fog and sun glare limit the performance of certain

sensors, DSRC-based V2X is a highly reliable sensor in any weather or lighting conditions.

Traffic light state and timing: Traffic efficiency is enhanced using DSRC. Vehicles obtain the

traffic light green signal cycle for optimizing their arrival, and traffic lights may even adjust based on

arriving vehicles.
