Rise of Automotive Electronics
Over the past few decades, there has been a tremendous rise in the use of electronics and software in automobiles. Where cars were once purely mechanical machines, they now contain dozens of electronic control units (ECUs) that rely on sophisticated software to operate critical functions like engine management, braking, stability control, entertainment systems and more. This shift was driven by consumer demand for new features as well as safety and emission regulations that required advanced vehicle control technologies. By the late 1990s, the average vehicle contained over 100 million lines of code powering everything from anti-lock brakes to navigation and multimedia systems.
New Challenges in Software Development
The growing sophistication of Automotive Software brought new challenges for vehicle manufacturers. Software bugs could potentially cause safety issues, so automakers had to adopt more rigorous engineering practices for developing safe, reliable code. They also needed to architect electronic systems so that critical functions had backup options in case of any software faults. At the same time, delivering new digital features to consumers required constantly improving infotainment and connectivity software on short development cycles. This placed pressure on automakers to streamline internal processes and work more closely with external software suppliers and partners.
Security Becomes a Top Concern
As vehicles became more connected through telematics systems, wireless firmware updates and integrated mobile devices, cybersecurity quickly emerged as an existential concern for the industry. Hackers have demonstrated the ability to remotely hack into vehicles to track locations, disable security features or even cut power to critical systems like brakes. Automakers are investing heavily to bolster security across supply chains and shut out cyber threats from telematics networks, Bluetooth pairing, wireless charging ports and other potential entry points. Going forward, automotive cybersecurity will involve continuous monitoring, rapid patching of vulnerabilities and new architectures that isolate control systems.
Role of Over-the-Air Technology
One strategy automakers are using to strengthen security as well as deliver ongoing improvements is over-the-air (OTA) technology. OTA allows carmakers to wirelessly update vehicle software after the point of sale, whether for fixing bugs, rolling out new interfaces or deploying security patches. This helps avoid expensive physical recalls and gives consumers access to the latest features without a dealership visit. OTA greatly enhances the software maintenance process but also introduces management challenges around change control, data usage and failure recovery processes. Leading automakers have also started using OTA to remotely provision new digital services for subscription-based offerings.
Growing Software Capabilities
The core functions served by automotive software will also continue to evolve rapidly. Advanced driver assistance systems rely on sophisticated algorithms and sensor fusion to enable semi-autonomous features like adaptive cruise control and lane keeping. Connected services powered by cloud infrastructure give drivers access to live traffic, fuel pricing, remote diagnostics, concierge help and more. Infotainment clusters are becoming more like mobile devices—running full operating systems, apps stores and digital assistants for media, navigation and vehicle settings. Software defines the user experience through large in-vehicle touchscreens and head-up displays. It will play a key role in the introduction of electric and autonomous vehicle technologies as the industry transitions in the coming years.
New Software Skills and Talent
In order to develop these increasingly sophisticated vehicle software systems, automakers must recruit and train engineers with skills spanning fields like artificial intelligence, security, cloud development and human-machine interfaces. They also require professionals with automotive industry expertise who understand the stringent safety and reliability requirements for mission-critical vehicle functions. The talent shortage has driven some manufacturers to partner with tech firms and devise new learning programs. There has also been rising adoption of agile methodologies to support quick innovation cycles and new methods like model-based development and over-the-air systems to streamline the software engineering process. Attracting diverse talent and fostering a culture of creativity and experimentation remain ongoing challenges as digital capabilities continue refining the driver experience.
Developing Secure Software Supply Chains
Another piece of the software puzzle is managing relationships with external suppliers who provide components, algorithms and services. Automakers must implement security clauses and verification testing for third-party code integrated into vehicles. This is made more complex as software content is sourced globally from partners specializing in diverse areas from telematics to advanced driver assistance. Techniques like open-source software monitoring, third-party code reviews and network segmentation can help automakers secure increasingly fragmented supply chains. Long-term, Blockchain and digital twin technologies may provide new solutions for transparently tracking all software changes from concept through the product lifecycle. As software powers more vehicle functions at higher stakes for safety and reliability, supply chain governance will remain a logistical challenge.
Improving Processes through Experience
While the road ahead holds unknowns, automakers have significantly strengthened their software capabilities through ongoing work in this area. Lessons learned from issues and successes are constantly refining governance practices, engineering techniques, security measures, talent strategies and other management levers. Vehicle software architecture is also evolving through modular, scalable designs and redundancy planning. The application of learning methodologies from sectors like aviation safety, technology security and open-source communities aids continual process improvement. Overall, vehicle software development has risen in maturity and discipline. Major industry players now recognize its importance as a strategic investment for competitiveness and responsibly delivering tomorrow's digital mobility experiences. With a balanced focus on protection, performance and progress, automotive software will drive the industry forward amid an exciting time of transition and innovation ahead.
