Volvo Car Group
(Volvo Cars), the Swedish Transport Administration (Trafikverket) and the
Norwegian Public Roads Administration (Statens Vegvesen) are joining forces in
a pilot project in which road friction information from individual cars is
shared within a cloud-based system. The real-time data about slippery patches
on the road are used to warn vehicles nearby, at the same time as it
contributes to making winter road maintenance more efficient.
Erik Israelsson, Project Leader Cooperative ITS (Intelligent Transport System) at Volvo Cars.
“The pilot is one of the first practical examples of the way
communication between vehicles over the mobile network enables vehicles to
‘speak’ to each other and with the traffic environment. This can contribute to
making traffic safer,” says Erik
Israelsson, Project Leader Cooperative ITS (Intelligent Transport System) at
Volvo Cars.
“We have 50 test cars on the roads, and next winter the
fleet will grow considerably. Our aim is to make the technology available for
our customers within a few years,” he adds.
Using the mobile network
When the Volvo test car detects an icy or slippery road
patch, the information is transmitted to Volvo Cars’ database via the mobile
phone network. An instant warning is transmitted to other vehicles that are
approaching the slippery area, making it possible for the drivers to take
immediate action to avoid a critical situation.
A slippery road warning on the instrument cluster alerts the
driver. The application in the vehicle will be designed to adapt the driver
warning to match the severity level based on the vehicle speed and the present
road conditions.
Improved winter road
maintenance
The information about the icy patch is also sent to the road
administrator as a complement to existing measurement stations along the road.
The data can help the road administrator and their contracted entrepreneurs to
better plan and execute winter road maintenance and quickly address changed
conditions.
“When the road administrator has access to information from
a large number of cars, the data can be used to make winter road maintenance
more efficient. The information could help to improve road safety further for
all road users. This could also reduce the use of salt when not needed and
minimise the environmental impact,” says Erik Israelsson.
Volvo Cars recognizes that the maintained integrity of
end-users is an important aspect of the system. The information shared with the
road administrator will not include data of unique vehicles. The aggregated
information is used solely to describe the present status of the road network.
Ambitious
connectivity strategy
Volvo Cars strategically invests in and initiates
partnerships to create cloud-based solutions, and the slippery road warning is
the first safety feature in the Volvo cloud. The development of sophisticated
communication via the mobile network is part of the company’s aim to offer
customers a fully connected experience.
“This is only the beginning. In the future we will have
increased exchange of vital information between vehicles,” says Erik
Israelsson. “There is considerable potential in this area, including safer
traffic, a more comfortable drive and an improved traffic flow.”
“The strategic focus on connectivity within our new Scalable
Product Architecture paves the way for more cloud-based safety solutions. This
will bring us closer to our safety vision that nobody should die or suffer
serious injuries in a new Volvo car by the year 2020,” concludes Erik
Israelsson.
