Ericsson and partners test new safety features on 5G self-driving bus

The 5G Ride self-driving bus project in Sweden has moved closer to full operations following a successful trial of remote digital monitoring and on-board digital safety services near Ericsson’s company headquarters in Kista, Stockholm.

The partners say the project has successfully trialled new safety features which explore how 5G and remote monitoring of vehicles via control towers could help to facilitate the introduction of self-driving electric buses in urban environments in a safe way.

Partners Ericsson, Urban ICT Arena, Intel, Keolis, T-Engineering, and Telia started the project in September 2020 with the inauguration of a temporary bus route on the island of Djurgården, Stockholm.

Throughout 2021, the project partners say they continued to develop the Connected Control Tower concept, using a 5G connection and a combination of new digital safety features, to monitor and manage fleets of self-driving vehicles on public roads, as well as enhance the safety and security of passengers onboard.

As part of the project the partners recently conducted tests using the self-driving 5G Ride electric minibus in Kista, Stockholm.

Ericsson provided the technical solution for the 5G-connected control tower and Telia provided connectivity in collaboration with Ericsson. Intel focused on analytics in the bus for increased passenger safety. T-Engineering delivered the vehicle and self-driving technology, working closely with Ericsson to integrate the minibus with the control tower. The initiative is also backed by Vinnova and Drive Sweden.

They say the project’s ambition is to support efficient and sustainable public transport where operators in the control tower can manage fleets of autonomous, electric vehicles to improve traffic planning and route optimisation which will lead to a more cost-effective and environmentally smart transport system.

Jan Jansson, Mobility Services Developer at bus operator Keolis, said, “On today’s buses, you can turn to the driver for help. It is a security for the passengers, especially for older person, that you feel welcome and taken care of. With the help of new technology, we can create the same experience on self-driving buses. It can be about quickly getting in touch with the operators in the control tower via simple digital interfaces on the buses.”

The partners explain this concept is one of many new safety features which are being investigated in the latest trials. Another concept is the use of artificial intelligence to analyse data from onboard sensors, with the ambition to proactively alert control tower operators in potential emergency situations, or even to identify forgotten passenger objects.

In addition to working with the journey on board, the project has also made progress in developing the integration between the control tower and the bus. The vehicle is connected to the control tower through a high-performance 5G network, enabling real-time communication between both the self-driving bus and the central control tower. For example, operators in the control tower can remotely command and even control the vehicle if necessary.

Marcus Gårdman Lead Design Technologist, Ericsson, added, “The 5G network’s unique technical features, including extremely high data speeds combined with low latency, means that the connected buses can respond in real time to commands from the centralised control tower. This delivers a critical and powerful foundation for the safe and secure remote-control of vehicles and is an important step to manage buses and public transport in a smart and sustainable way.”

Ericsson says it is not only driving research and development into connected vehicles, which includes collaborating closely with leading automotive companies, bodies and standards. R&D areas include autonomous vehicles, intelligent advanced driver assistance systems, vehicle-to-anything (V2X) communication, the connected vehicle cloud and more.
