Summary

• The 12 October Paris presentation covers four distinct roadmaps, including software-defined vehicles and automotive hardware.
• Two DIGITAL-funded projects will establish an ECAVA secretariat and industry collaboration platform.
• Cities and regions can submit expressions of interest in ADACities until 20 October.

The European Commission says the European Connected and Autonomous Vehicle Alliance (ECAVA) will present four technology and deployment roadmaps in Paris on 12 October, alongside the Paris Motor Show. The programme is intended to connect shared European engineering priorities with the industrial commitments needed to bring new vehicle systems into production.

Announced on 9 October, the meeting follows ECAVA’s first international forum in Brussels in June. Two projects supported through the DIGITAL programme will also be introduced. One will establish a secretariat to coordinate alliance members, working groups and meetings, while the other will develop a collaboration platform for manufacturers, suppliers, technology companies, researchers, cities and public authorities.

These projects provide coordination rather than operational autonomous vehicle services. Their value will depend on whether participants use the new structures to make decisions on technical specifications, investment and implementation. A roadmap agreed in discussion is not the same as a component qualified for automotive manufacture.

The software-defined vehicle roadmap describes an open, competitive European ecosystem by 2030. Instead of imposing one mandatory software stack, the Commission says the emphasis is on common architecture contracts, interoperability and reusable open source components. Safety-critical elements receive particular attention because they cannot be treated as interchangeable consumer software.

Shared interfaces could make it easier for suppliers to contribute software to more than one vehicle programme. Yet interoperability must be tested against production software, security requirements and the operating life of vehicles. An agreed interface can reduce duplicated integration work, but it will not settle questions about liability, maintenance or the cost of keeping different systems compatible.

The hardware roadmap has been developed with the Alliance for Processors and Semiconductor Technologies, known as ALLPROS. It proposes a chiplet-based European computing platform, in which different processing components are combined to meet particular performance requirements. That creates potential flexibility compared with designing all functions into a single device.

Automotive deployment imposes constraints on such designs. Packaging, energy consumption, reliability, supplier availability and qualification all influence whether a flexible processing architecture can be produced economically. The Commission presents the chiplet approach as a proposal, not a platform already adopted across the European automotive industry.

On autonomous driving, ECAVA’s group covering data, artificial intelligence and the automated driving software stack is developing a common strategy. The Commission says this work remains under discussion with industry and the alliance steering committee. It would therefore be premature to describe that strategy as a final agreement or an implemented European standard.

The deployment roadmap addresses Level 4 automated driving, where a vehicle can undertake the driving task without continuous human supervision within defined operating conditions. This does not mean that the same vehicle can drive autonomously on every road or in every weather condition. Commercial services still require safety assurance, maintenance, operating procedures and a viable demand model.

The Autonomous Drive Ambition Cities initiative, ADACities, is intended to help cities and industry move beyond disconnected pilot projects. Cities and regions can express interest until 20 October. Their role matters because infrastructure, public transport integration, accessibility and procurement can shape the feasibility of an autonomous service as much as onboard technology.

The first ECAVA international forum met in Brussels on 23–24 June, providing the earlier setting for this cooperation. After the roadmap presentations, a panel will address industrial commitment, the sequencing of public and private finance, supply chain execution and the regulatory conditions for investment. The Commission says the Paris messages will also be taken to the automotive electronics ELIV congress in Baden-Baden on 14–15 October.

The programme draws on the Commission’s Automotive Action Plan and Apply AI Strategy, but these broader policies do not guarantee individual investment decisions or deployments. ECAVA’s agenda supplies an organising structure for European vehicle development, with the software roadmap extending to 2030 and nearer-term work planned around collaboration and deployments. What remains to be demonstrated is whether manufacturers and public authorities adopt shared designs and operate Level 4 services beyond demonstration funding.
