The emergence of 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.
V2X is essential for safe and efficient Autonomous Driving:
Accurate vehicle information: Other vehicle sensors estimate vehicle data. Only V2X can provide accurate speed, heading, status of brake pedal, and more.
Sensing obstructions: 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 all environmental conditions: While fog and sun glare limit the performance of certain sensors, V2X is a highly reliable sensor in any weather or lighting conditions.
Traffic light state and timing: Traffic efficiency is enhanced with V2X. Vehicles obtain the traffic light green signal cycle for optimizing their arrival and traffic lights may even adjust based on arriving vehicles.
