5G ADAS use cases
Connected vehicles benefit from a large variety of 4G-enabled services. Some are directly experienced by the drivers and passengers, such as connected mobility services (mobility as a service, dynamic traffic info, etc.) and infotainment. Others, like telematics and autonomous fleets management, improve the operational efficiency of the vehicle and are primarily managed by vehicle manufacturers. Now 5G will take ADAS a step further.
5G aquaplaning alert
A vehicle detects a risk of aquaplaning on a road segment, thanks to its connected cyber-tires. The information transmitted by 5G from the vehicle to the network is collected by the edge cloud and propagated in real-time over 5G to vehicles following behind. The receiving vehicles visualize the danger of increased risk of aquaplaning to the driver with a non-invasive AR interface.
Hidden pedestrian alert
A distracted pedestrian is warned about an approaching vehicle through his smartphone. The driver of the vehicle also gets a warning about a pedestrian heading towards or close to the road. When the pedestrian is visible from the vehicle, AR technology is used to enhance visibility and warnings about pedestrians close to the vehicle. Thanks to eye-tracking technology, the system can even adjust the warning to the vehicle driver, assessing whether the driver has likely seen the pedestrian, or not.
Ericsson Research partnered with leading companies such as Audi, TIM, Pirelli, Qualcomm, Italdesign, Tobii and KTH Royal Institute of Technology to demonstrate the future of ADAS over TIM’s commercial 5G network. Thanks to 5G’s low and controlled latency and to edge cloud deployment, 5G can act as the fabric that enables communication among innovative technologies, in this partnership exemplified by cyber-tires, eye-tracking devices and in-vehicle augmented reality (AR) displays. The demonstration was held as part of a 5G Automotive Association (5GAA) event held at the historical rooftop track Lingotto in Torino, Italy, in front of journalists, partners and even competitors.
One connected vehicle services segment that has received major public attention in recent years is Advanced Driver Assistance System (ADAS). ADAS can also be seen as a steppingstone towards full autonomous driving (AD). Connectivity is commonly regarded as a complement to increasingly advanced on-board sensors (RADARs, LIDARs, cameras, etc.), by delivering real-time, reliable information between vehicles and their cloud-based service providers, which in turn gather data from other vehicles and road infrastructure. A cloud platform such as the Ericsson Connected Vehicle Cloud is an essential enabler for some such services, by aggregating, processing and exposing relevant data with increasingly tight integration with the mobile network. While several services can already be deployed today using 4G’s ever increasing road coverage, for example Australian-first C-V2X trial, it is exciting to see where ADAS technology will be heading once 5G is available on major roads and in urban areas.
Ericsson and Veoneer have demonstrated connected ADAS together several times. One example is cyclist safety, where both the car driver and the cyclist receive visualize notifications when they are heading into the same geographical area. Other examples are notifications about road workers and emergency vehicles, both using a technology known as geofencing to determine in which geographical area notifications should be distributed.
