Subaru has installed a local sub-6 5G standalone (SA) network covering the entire circuit at the Bifuka Proving Ground of the Subaru R&E Center (Hokkaido) and has begun a demonstration experiment of cooperative driving automation.
Subaru Corporation is a local sub-six*1 5G Standalone (SA)*2 We have built a network that covers the entire course at the Subaru R&E Center Bifuka Proving Ground (Hokkaido) and have begun demonstration experiments of automated cooperative driving.
The Subaru R&E Center has previously focused on researching autonomous driving systems that utilize mobile communications, but this time it has begun a demonstration experiment of cooperative control* by taking advantage of the high-speed and highly reliable connection environment of the local 5G SA network.3Multiple autonomous vehicles merging and other maneuvers, remote vehicle control, etc.*4.
A total of seven Sub-6 wireless base stations were installed around the circuit course to enable remote control of cooperative driving automation throughout the area. The equipment consisted of the NOKIA Digital Automation Cloud (NDAC).*5 The system was provided by Nokia Solutions and Networks Japan, LLC, and installation was made possible with the support of NS Solutions Co., Ltd. This marks the first time that a Japanese automaker will build a local 5G network on a test course.
Subaru will continue to engage in research and development with the aim of further reducing accidents and providing “enjoyment and peace of mind” in the mobility society of the future.
Autonomous driving through cooperative control
Autonomous driving with remote vehicle control
*1: 5G infrastructure that uses frequency bands below 6GHz. A single base station can cover a wider area than millimeter waves. High directionality and wide bandwidth enable high-speed, large-volume data transmission.
*2: A 5G network that can be built and operated autonomously using only 5G, without requiring communication facilities from a mobile network operator (MNO) or 4G for control signals.
*3: Routes and other information are calculated on the server side and provided to vehicles as operation plans.
*4: The server calculates the data required for driving plans and vehicle control, and issues instructions for vehicle driving control.
*5: Local 5G standalone solution provided by Nokia Solutions and Networks Japan, LLC.
