What is the background and core technological capability of TTTech Auto? 
TTTech Auto was founded in 2018 by TTTech Group and technology leaders Audi, Infineon and Samsung to build a global, safe vehicle software platform for automated and autonomous driving. In 2022, the company raised USD 285 million (EUR 250 million) from Aptiv and Audi in its latest funding round. At TTTech Auto's headquarters in Vienna, Austria, and its subsidiaries across Europe and Asia, 1,100 employees work with leading car manufacturers on their software-defined vehicle, ADAS and autonomous driving programs. The company has acquired and invested in technology companies in the UK, Spain, Turkey, China and Central and Eastern Europe.

You took on the role of CEO of TTTech Auto in 2022. What significance did that year hold for the automotive industry's evolution and the future trajectory of TTTech Auto? What in your background and experience prepared you to become CEO of TTTech Auto? 
 Before becoming the CEO of TTTech Auto in 2022, I had over 20 years of managerial experience in the automotive industry. Immediately prior to joining TTTech Auto, I served as the CEO of OSRAM Continental, a joint investment firm between OSRAM and Continental with over 1,500 employees. Previously, I held executive positions at Bosch, overseeing ADAS and vehicle electronics development in Germany and China. My career began as a research engineer at DaimlerChrysler, where I obtained a Ph.D. in the field of radar and infrared-based pedestrian detection systems.

TTTech Auto now aims to succeed in the innovative changes sweeping the automotive industry, particularly in the transition to SDVs and safety-critical applications. I hope that my past experiences in driving growth and innovation will contribute to TTTech Auto's continued success in the rapidly evolving automotive landscape.

TTTech Auto's innovative approach, 4SDV(System, Safety, Security, Software), plays a crucial role in implementing safer, more efficient, and user-centric SDVs in the industry.           

SDV enablers have catchphrases like 'code-first approach,' 'chip-to-cloud,' 'data-centric,' 'scalability,' 'customer experience,' etc., depending on their position. What does '4SDV' mean for TTTech Auto, and how does it differentiate itself? What are the challenges TTTech Auto sees in SDVs, and how can they be addressed? 
The company specializes in safe software and hardware platforms for safety critical applications such as automated driving and beyond. With its cutting-edge technology solutions in more than 4 million cars on the street, TTTech Auto ensures safety and electronic robustness of SDVs for safer and more convenient driving. TTTech Auto's innovative approaches to System, Safety, Security and Software (4SDV) make it a key player in helping the industry move towards safer, more efficient and user-centric vehicles.

The automotive industry is clearly heading towards a future dominated by SDVs. According to latest statistics it assumed that by 2030 more than 90% are SDVs. SDVs must not only provide advanced functionality, but also ensure the highest level of safety and security concurrently. Already at a very early stage, TTTech Auto recognized that software alone is not reflecting the complete challenge of SDVs which are among the most complex software products in the world, exceeding even the complexity of aircraft software. 

TTTech Auto promotes a holistic approach to SDV development, known as the 4SDV approach, which emphasizes the interconnected roles of System, Safety, Security, and Software. Unlike traditional software-centric approaches, 4SDV recognizes that safety and security are system-level properties and cannot be achieved through software alone but require careful consideration from the outset of vehicle development. By integrating safety and security into the design process, TTTech Auto ensures that SDVs are not only advanced in functionality but also meet the highest standards of safety and security. Designing a 4S-defined vehicle will lead to faster development times and better updateability which are both important customer benefits.

By 2030, digital services could generate as much as $1.5 trillion in additional revenue for the global industry, rising to $3.5 trillion, amounting to 40 percent of total automotive industry revenue by 2040, according to research by consultancy Accenture. Meanwhile, in 2030 the market for over-the-air-delivered features and subscriptions is expected to reach $14 billion, up from $3.3 billion last year, according to data from consultancy Deloitte. According to a study from Deloitte, the percentage of software-defined vehicles on the road is forecast to grow fast - from 2.4% in 2021 up to more than 90% in 2030. 

Among the various issues in implementing Zonal architecture, what problems can TTTech Auto address, and what solutions does it offer?
 When it comes to implement zonal architectures, the key challenges here are integration, integration speed and robustness. With SDVs more and more functionality is integrated in domain or central compute units. To abstract SW functionality from the hardware, a very powerful middleware platform is necessary. Moreover, partitioning between functionalities and between different safety classes is needed as well as incremental updates without re-validation become key. Faster validation and homologation process supported by cloud approaches with time and data determines are necessary. 

All of this can be provided by the company's flagship product “MotionWise” which is a horizontal middleware platform designed specifically for distributed architectures and safety-critical real-time domains. It provides solutions for task scheduling, network communication, and safety-critical functionality, enabling faster development times and better updateability for SDVs.

With “MotionWise” TTTech Auto provides solutions for scheduling, so that the task scheduling (running on-chip) and the network communication (so-called network schedule for TSN) are created by their “MotionWise” tools in a single step. This ensures end-to-end latencies are met and efficient resource usage.

TTTech Auto provides their own communication solution for Ethernet and shared memory communication, which is to be deployed on both zonal ECUs (electronic control units) as well on HPCs (high performance computers). The communication stack and its configuration is fully abstracted from the applications. Communication is automatically created from the system model. It covers both signal-based and service-oriented communication and includes S2S - signal to service. The solution also supports ASIL D safety level on each node and CPU.


TTTech Auto's flagship product, 'MotionWise,' is a system-wide middleware platform specially designed for domain architecture and essential real-time safety, providing essential functionalities for task scheduling, network communication, and safety. This platform reduces SDV development time and increases updateability.

TTTech Auto has invested in companies like Zetta Scale. What is TTTech Auto's perspective on DDS?
 TTTech Auto made a strategic investment in Zetta Scale, underscoring its commitment to innovation and advancement in the realm of software-defined vehicles. With this investment, TTTech Auto aims to leverage Zetta Scale's cutting-edge Zetta Auto software solution to address the evolving challenges of SDV communication. It is designed to provide high-performance communication capabilities while facilitating highly integrable yet decoupled development processes. This innovative approach aligns perfectly with TTTech Auto's vision of driving forward the development of SDVs that are not only technologically advanced but also robust and reliable. This strategic move recognizes the relevance of Data Distribution Service (DDS) technology in the automotive industry. DDS has emerged as a key enabler for automotive communication systems, offering several advantages that align with TTTech Auto's objectives. As a data-centric middleware, DDS facilitates encapsulated development while maintaining integrability with existing systems - a crucial factor in the automotive context where interoperability is paramount.

TTTech Auto actively collaborates and participates in initiatives like SDVerse, as well as with major players like QNX and Mobileye. How can such collaborations bring value to customers in SDV development?
