Common Vehicle Interface Initiative

What is W3C?

• World Wide Web Consortium
• Standards body for the Web
• Founded by inventor of Web - Tim Berners-Lee
• Hosts: MIT, Beihang, Keio, ERCIM
• ~450 members

Common Architecture with Partners

Why W3C is doing Auto Standards?

• Need for a robust, common application ecosystem
• Reduce fragmentation by competing proprietary approaches
• Future of transportation will require interoperability
• More developers for the Web than any other platform
• Web has proven itself and transformed industries
• Connected vehicles will be relying on Web services
• W3C has a long history of providing higher level interfaces to developers

Common Vehicle Interface Initiative Stack

W3C+GENIVI Joint Initiative

• VSS
• VISS
• In-Vehicle Best Practices
• ExtVeh
• VSSo, GraphQL...
• RPC
• Down stack into controllers, discussing with AutoSAR

W3C Vehicle Information Service Specification (VISS)

• Service on the vehicle
• Common data model (GENIVI VSS)
• ~1000 signals, more to be added, extensible*
• Web Sockets, next gen also HTTP REST
• Granular accesss control per application
• Requests or Subscribe (stream)

Implementers

Few of the known implementations

In-Vehicle Application Best Practices

What next?

• Common API alone not enough to address concerns
• Common sense and controlled inclusion
• Signal read/write access control, polling frequency
• Govern IVI/TCU computing resources, outside connectivity, bandwidth
• Third party signal handling
• Call for Participation
• Ensure use cases/needs met

Remote Procedure Calls and Service Catalog

• Proposal from JLR
• Specific read/write signal instructions would vary for common tasks
• Digital Key, roving delivery...
• Facilitate partnerships with Tech companies
• API at W3C / Catalog at GENIVI

VSSo

• Ontology - human (engineer) and machine readable
• Built on top of our current data model - GENIVI VSS
• Combining disparate datasets readily - Knowledge Graph
• Artificial Intelligence / Machine Learning - in-cloud & in-vehicle uses
• Bringing telematics data to the cloud
• Enables Big Data/Analytics
• W3C Web of Things (WoT)

IoT / W3C Web of Things (WoT)

• IoT Fragmented worse than Auto, W3C WoT provides bridge
• VSSo and W3C WoT allow for vehicle to be any arbitrary thing on IoT
• BMW has presented proof of concept demo
• Can provide mapping to OEMs existing service APIs

W3C+GENIVI CVII Just a piece of the puzzle

• Established coordination on data models among related SDO
• AutoSAR (proposed to board)
• Open Geospatial Consortium
• ISO TC22 SC31 Extended Vehicle
• ISO TC211 Geospatial
• ISO JTC-1 SmartCities
• ISO TC204 ITS

Common Automotive Platform Benefits

We learned a few things building the Web

• More willing partners
• Less engineering resources needed to integrate
• Wider cybersecurity peer review
• More vendors/providers able to create supportive products/services
• Avoid vendor lock-in
• Net lower cost
• Larger market with faster growth

Common Adoption Path

Where in the stack are we talking about?

• Re-architecting vehicles costly, production timeline
• Choose common data in the cloud first
• Consider pain points with suppliers
• Long term in-vehicle benefits and proven adoption at cloud level will show industry trend

Adoption Path Strategy

Develop standards, connect vehicles... profit

• Map your data to VSS in cloud for 'an easy win' - John Schmotzer, Ford
• Choose platform[s] based on your & customer needs
• Build products and services on top - real value
• In-vehicle abstraction layer (OEM, supplier, solution provider)
• Go further down the stack into control units, streamline industry and dramatically reduce cost

Telematics Data Marketplace

• Enable additional revenue streams: > $140B by 2030
• Need common data format to have mass market appeal
• Clear demand for telematics data
• Interest in W3C Auto standards from prominent data consumers (government regulators, insurance commissioners, mixed fleet managers - more information than RFMS/ELD)
• Task force exploring data quality topics - add value to your data!
