Ethernet TSN and Automotive Ethernet: The Backbone of OTA, Data Aggregation, and Vehicle Diagnostics
Today’s vehicles are data-driven machines. They run on software as much as on fuel. To stay secure, updated, and reliable, they need a communication backbone that can handle massive amounts of data without delay. That backbone is automotive Ethernet, strengthened by TSN for time-sensitive communication. Together with standards like eSync and SOVD, and with Excelfore eDatX, this foundation supports automotive OTA, efficient vehicle diagnostics, and large-scale automotive data aggregation.
This isn’t just about faster
networks—it’s about building vehicles that improve continuously.
Why automotive Ethernet matters
Older in-vehicle networks, such as CAN
and LIN, cannot meet modern demands. High-resolution cameras, ADAS functions,
and infotainment all compete for bandwidth. The resources of the cloud can not
improve devices that can not be addressed and reached remotely.
Automotive Ethernet solves this with speed,
flexibility, and scalability.
●
High bandwidth: Supports gigabit speeds
needed for data-heavy systems.
●
Standardized addressing: Uses Internet Protocol (IP)
methods to address each endpoint, allowing remote resources to access and be
accessed by each electronic device on the network
●
Standardized protocols to extend IP addressing: Works seamlessly with SOME/IP and DoIP to support
service-oriented and diagnostic functions. These protocols can make use of the IP addressing of devices on the Ethernet network
to provide remote access to subordinate devices on non-IP buses. OEMs can keep
their legacy ECUs on CAN and LIN, and enable remote access through an Ethernet
backbone with SOME/IP and DoIP.
●
Deterministic performance: With Ethernet TSN, safety-critical data
always arrives on time.
This makes Ethernet the natural backbone
for updates, diagnostics, and data management in connected vehicles.
Excelfore can provide OEMs the protocol
stacks needed to create an Ethernet backbone.
And once it is in place, Excelfore offers the solutions OEMs need to
create best-in-class cloud connectivity.
eSync technology and automotive OTA
Connectivity alone is not enough. Updates
need orchestration. That’s where eSync
technology comes in.
It provides a bi-directional pipeline between the cloud and the devices in the
vehicle:
●
Automotive OTA updates flow down securely
to every ECU.
●
Diagnostics and telemetry
flow back up for monitoring and analysis.
For OEMs, this means every ECU in every
vehicle in the fleet can receive secure, efficient OTA software improvements —keeping vehicles safer, more capable,
and future-ready.
Data aggregation with eDatX
Vehicles generate enormous amounts of
data every day. Not all of it is useful. The Excelfore eDatX platform enables intelligent automotive data aggregation, ensuring only selected data is sent to
the cloud.
Key advantages:
●
Efficient data reduction: Reduces data by 99.9% or
more
●
Efficient data selection: Collects, organizes and sends useful data.
●
Fleet-wide insight: Helps identify trends
across thousands of vehicles.
●
Scalable design: Works across different
domains and vehicle models, for massive numbers of vehicles
This enables OEMs to optimize performance
and reliability, reduce operational costs, and design better vehicles.
More innovative vehicle diagnostics with SOVD
Diagnostics are also changing.
Traditional methods relied on repair-shop tools. New approaches, such as SOVD (Service-Oriented Vehicle Diagnostics),
utilize IP-based remote access instead.
With SOVD,
integrated with eSync and
supported by automotive Ethernet,
service teams can:
●
Monitor vehicle health in
real time.
●
Run advanced diagnostics
remotely.
●
Integrate seamlessly with
cloud platforms, such as AWS IoT Core.
This results in faster problem
resolution, reduced downtime, and fewer recalls.
Why this matters for OEMs and fleets
The combination of Ethernet TSN, automotive
Ethernet, and Excelfore’s platforms delivers measurable value:
●
Faster and more reliable automotive OTA updates.
●
More innovative vehicle diagnostics with remote access
and predictive insights.
●
Actionable intelligence
from automotive data aggregation.
●
Lifecycle competitiveness
as vehicles continue to improve after launch.
With eSync
technology, eDatX, and SOVD, OEMs gain the tools to reduce
costs, unlock new revenue streams, and deliver safer, smarter vehicles.
The bottom line
The future of mobility depends on
networks that are fast, reliable, and adaptable. Automotive Ethernet provides the
backbone. Ethernet TSN guarantees
time-sensitive performance. eSync
technology and eDatX bring
secure updates and efficient data management. SOVD makes diagnostics smarter. Jointly, these solutions redefine
what vehicles can do—not just at launch, but throughout their entire lifecycle.
