V2X proof-of-concept extends driver's field of view
The project, which used lidar sensors and vehicle-to-everything technology to “look around the corner”, could help advance the safety of autonomous driving.
A consortium of three companies have completed a proof-of-concept project that claims to confirm the ability of an integrated system to warn drivers of unseen hazards ahead.
Silicon Valley lidar specialist Cepon, ALP.Lab, an Austrian technology provider of autonomous vehicle testing solutions, and sensor and connector firm TE Connectivity undertook the project, which reportedly extended a driver’s field of view.
Lidar sensors were mounted at an intersection to “look around the corner” and warn of a wayward pedestrian approximately five seconds before they would be visible otherwise.
Vehicle-to-everything
Called Periscope, the project brought together Cepton’s intelligent 3D lidar perception, ALP.Lab’s expertise in system integration, testing and data analytics, and TE’s vehicle-to-everything (V2X) solution. The three companies created a solution that communicates additional information about road conditions in real time to the vehicle providing more time to react to potentially dangerous situations and enhancing overall safety.
“The results from Periscope are impressive,” said Christoph Knauder at ALP.Lab. “We tested a scenario where a pedestrian around a corner started to cross the road and thus stepped into the lane of the approaching test vehicle. The driver was able to be warned of the approaching pedestrian five seconds before the pedestrian became unblocked and appeared in his field of view.
“V2X communication will be the breakthrough technology to advance the safety of autonomous driving and intelligent future mobility”
“The high-resolution 3D sensing capabilities of Cepton lidars allowed us to generate smart analytics of the situation, while the V2X system by TE Connectivity enabled real-time communications to the vehicle, making it possible to drive an intelligent decision before it’s too late.
“We believe Periscope has proven the safety potential of smart infrastructure in the future of autonomous mobility. We look forward to extending our collaboration to test the solution in more use cases.”

The companies are planning to collaborate on quantitative testing in the coming months to confirm this initial finding.
While recent enhancements in advanced driver assistance systems (ADAS) are expected to help reduce crashes between vehicles and bicyclists, pedestrians, and e-scooters, the complexity of road conditions leaves a critical gap where not all road users are within the vehicle’s field of view when early warning is needed. This reduces the ability of the vehicle to react and prevent potential collisions.
Periscope was precisely designed to expand the awareness of a vehicle and its driver of the overall traffic situation beyond visible surroundings and the onboard sensors’ reach via real-time communications of high-precision, smart data collected from the infrastructure.
Ralf Klaedtke, chief technology officer, transportation solutions, TE Connectivity, added: “The results of the V2X Periscope are yet another proof point that V2X and sensing technology is ready to save human lives in road traffic every day. V2X communication will be the breakthrough technology to advance the safety of autonomous driving and intelligent future mobility. This technology will play a key role in TE’s future.”
