Standards in CAD

Modern infrastructure will increasingly incorporate new components which increase the robustness of the system. The future of CAD is bright and offers the long-term promise of mobility that improves safety and transport operations while lowering the environmental impact. Therefore, at this point, we have to see a more standardised and active automated ecosystem. Providing a common interface to improve the economy of scale to reduce cost, which improves the integration of advanced functions in CAD. At global and European level, different standards developing organizations exist with the intend to inform wider industry thinking and accelerate the successful introduction of exciting pioneering technology.

European Standards

Many EU countries (e.g. France, Spain, and Sweden) have taken action to review the regulatory issues related to CAD, including testing of vehicles. Some EU countries (e.g. UK) have regulations favourable to testing and others (e.g. Italy and Germany) use a case-by-case approach. This suggests that EU member states are at different levels in terms of development, testing and deployment of CAD. For improved research and vehicle operation testing, an EU-wide harmonised regulation for CAD is required to support a legislative act.

CEN and ETSI are working on ‘Release 2 specifications’ to address more complex use cases in CAD. There is also a whole set of European standards and European standardisation deliverables developed by the European Standardisation Organisations (ESOs).


Challenges and future standards

Standards are a necessity to achieve interoperability between communicating parties especially when products from different vendors shall be able to communicate with each other. To this end one of the major benefit arising is the ability for the customer to choose any vehicle brand with considering any potential technology incompatibilities.

In the rapidly evolving industry of automated, connected, electric and hybrid vehicles, the ability to create real-world test scenarios, troubleshoot potential failures and maximize the chance of passing standards within the allotted time helps bring products to market faster. Therefore, standards must be timely, market-driven and produced in an inclusive way that supports EU policies and Europe’s leadership in international standardisation.

Automotive technology also requires extension to smartphone technologies and wirelessly connected smart infrastructure. Automation functions such as sensing and processing already include high speed connectivity to enable autonomy. However, only small part of the autonomous domain is regulated and standardized. The collected information about existing standards aims in providing an overview of existing solutions and approaches. This way a simple gap analysis will reveal crucial aspects which are not addressed and the need for future standardisation activities

Currently, many standardisation activities are underway in different countries for (pre-) standards used in the development and testing of connected and automated systems. OEMs on one side produce their systems for a global market. However regional differences in products are needed and compliance to different user preferences and regulations.

There are a number of best practices that may be utilized in the process of developing a technical standard.
