Driver assistance: Mobile devices – LTE-V2X-technology

Bosch, Vodafone und Huawei are currently testing LTE-V2X-technology on a part of German Motorway “Autobahn 9” close to Allershausen, Bavaria. The mobile devices technology allows real-time communication directly between cars. Vehicles will send information about speed, position and lane-changes to all connected cars and mobile devices within a range of 320 meters, thus helping to avoid traffic jams and accidents.
Vodafone is providing a high-end Mobile Network for the test track. Huawei is equipping cars and base-stations with modules for mobile communication. Bosch intends to integrate both modules and software an monitor vehicle performance.
In initial tests the partners intend to demonstrate how direct mobile communication between cars with very low latency networks is feasible in ways that differ greatly from the traditional WLAN-based approach. Mobile networks also ensure maximum reliability and improve coordination between the cars.
Initially, tests will involve real-time warning during lane changes. For instance, if a car is approaching at high speed from the rear, the driver will receive a warning. In later stages, the technology will be tested in additional scenarios, for instance warning of sudden slow-downs by the vehicle ahead. The object is to determine which functions can benefit the most from fast mobile data transmission.
