  • Unravelling complexity in a software-defined vehicles industry | Ubuntu

    Vehicles are becoming more connected, autonomous, shared and electric (the famous CASE acronym). While customers expect new features and upgradability, the software and hardware components enabling such innovations require a different system architecture to function. This is a major change for the automotive industry as it requires new software skills, methodologies and business models. At the same time, automotive manufacturers need to adhere to complex and strict industry standards, and uphold safety-critical functions. In this post, we will focus on the different challenges the industry is facing in terms of hardware and software complexity, cybersecurity and safety. We will also discuss how Original Equipment Manufacturers (OEMs) can learn from software companies to survive this transition towards software-defined vehicles and succeed. [...] On top of this, regulations are becoming very strict, forcing OEMs to provide patches and fixes to common vulnerabilities and exposures (CVE). Taking into account the previously detailed system complexity, it is becoming increasingly necessary to move towards a software-defined holistic context. Only a software-defined approach can provide the required flexibility and scalability that allows companies to comply with regulatory requirements while providing UX updates and handling hardware complexity. Of course, cybersecurity never only relies on software. Hardware vulnerabilities can also occur and usually lead to even worse consequences. Some hardware issues can be patched via software, but usually these CVEs remain valid throughout the system’s lifetime. For example, Meltdown and Spectre, two of the most widespread hardware vulnerabilities in the world, are still present and affecting tons of devices. This means that during hardware conception, cybersecurity must be taken into account in the specifications and system architecture in order to limit these vulnerabilities.
