Teens` smartphones to run road-safety system

Bonn, Dec 11 ( -- It sounds like science fiction, but German auto component maker ZF says it has come up with a cloud-based, intelligent road safety system which can effectively see around corners

X2 Safe detects hazards not yet visible to a driver and makes split-second decisions to prevent accidents.

It is set up to work with car-to-car, car-to-infrastructure and even people-to-people signals via smartphones.

The company says the technology could pave the way to widespread use of autonomous and other robot-driving systems.

X2 Safe can send warnings and also intervene by triggering emergency braking or avoidance systems. On today`s cars, these are normally activated using cameras and radar systems.

"Safety is the heart of autonomous driving," said Malgorzata Wiklinska, who heads the lab in charge of developing the algorithm for the system.

X2Safe gathers data on the position, direction and speed of all road users in the vicinity of the car, provided they are linked to each other via the cloud.

The movement data from vehicles, cyclists and pedestrians is fed into an algorithm which calculates whether a road user`s behaviour is "unsafe" and might lead to a collision.

The cloud gets its data from car sensors which register steering and brake movements. Pedestrians and cyclists automatically deliver data via their smartphones or a wearable chip.

In a typical situation where a pedestrian ignores a red light and walks across a road beyond the driver`s range of sight, the cloud sends the driver an audible and visible warning.

The pedestrian’s smartphone or smartwatch also starts to buzz and a graphic alert flashes up on the display screen.

Many young people are constantly online and this is an advantage for the new technology, since they can contribute movement data in real time, said ZF.

ZF will present the technology in prototype form at the upcoming 2017 Consumer Electronics Show in Las Vegas and hopes to market it later next year.

ZF said movement profiles are not stored, since as soon as a wearer stops moving, the collected data is deleted from the system.

Driver and pedestrian distraction pose a major risk. A US study has shown that drivers are distracted for more than half of their journey time.
