Automotive Embedded Systems: Future of In-vehicle Technology

Automotive embedded systems have become increasingly sophisticated over the years and are playing a pivotal role in enhancing vehicle safety, comfort and functionality. From basic engine control units to advanced driver-assistance systems, embedded software is powering the latest intelligent and connected car technologies. In this article, we explore the evolving role of embedded systems in automobiles and discuss market outlook for this key technology segment.

Introduction to Automotive Embedded Systems

An embedded system in automotive refers to a combination of computer hardware and software that is designed to perform dedicated functions within vehicles. Some of the core components of embedded systems include microprocessors, microcontrollers, sensors, actuators and embedded operating systems. These embedded systems largely control different electronic control modules (ECMs) within modern vehicles to monitor and manage various mechanical and electrical systems.

Some of the key functions performed by automotive embedded systems include engine management, transmission control, anti-lock braking, climate control, infotainment, and advanced driver-assistance. The processing power, data storage, and real-time responsiveness requirements of these applications have been growing exponentially with the rise of electric vehicles (EVs), autonomous driving technologies, and connected car solutions. This has made automotive embedded systems one of the most complex real-time systems being developed currently.

Rise of Advanced Driver-Assistance Systems

Coherent Market Insights explains technological advancements in automotive embedded systems market as followed:

Advanced driver-assistance systems (ADAS) such as adaptive cruise control, automated emergency braking, lane keep assist and blind spot monitoring have become increasingly common on modern vehicles. These active safety systems rely on sophisticated sensor fusion, computer vision, artificial intelligence and high-performance embedded platforms. For instance, a lane keep assist feature uses cameras, Automotive Radar and other sensors along with sophisticated algorithms running on embedded CPUs/GPUs to detect lane markings and vehicle position to keep vehicles centered.

The embedded software analyzes terabytes of sensor data in real-time to detect objects, interpret scenes and determine appropriate driving maneuvers autonomously. As autonomous vehicle technologies progress towards higher levels of automation, embedded systems with superior processing capabilities will be crucial to power safety-critical functions. Many automakers are developing customized ADAS systemson-chip (SoC) and domain controllers with capabilities beyond general-purpose CPUs. This trend is poised to revolutionize road safety.

Infotainment and Connectivity Solutions

Vehicle infotainment and connectivity solutions are also areas where embedded systems play a vital role. Modern infotainment systems deployed in vehicles leverage powerful embedded multimedia processors, large storage capacities and fast networking technologies. Functions ranging from navigation, wireless device mirroring to over-the-air updates are enabled and managed by the embedded infotainment core.

Similarly, technologies enabling vehicle-to-everything (V2X) communication for uses like remote diagnostics, traffic updates and autonomous driving heavily rely on embedded modems, radios and network coprocessors. The combination of high-speed in-vehicle networking standards like Ethernet, fiber optic cables and powerful network controllers within embedded systems have made seamless digital cockpits and connected mobility solutions a reality.

Evolution of Electric Vehicles

The rise of electric vehicles (EVs) poses both opportunities and challenges for automotive embedded systems. Advanced battery management systems, electric powertrains and vehicle control architecture require highly optimized real-time control systems. Technologies like vehicle-to-grid solutions and ancillary services also increase the processing and communications requirements.

The embedded systems powering EVs need to be more efficient to minimize energy consumption while delivering high performance for applications like regenerative braking. Moreover, as driving ranges and charger options expand with ongoing technology developments, over-the-air updates enabled by embedded modems will play a key role in improving vehicle usability over time. Overall, embedded platforms form the backbone enabling smarter, greener and more optimized electric mobility.

Cybersecurity in Automotive Systems

With increasing connectivity and software-defined capabilities in vehicles, cybersecurity is emerging as a crucial area of focus for automotive embedded systems. As attack surfaces and threat models evolve continuously, security measures need to be incorporated at the hardware root of trust level as well as different software stacks.

Functions ranging from secure boot, authentication, and access control to runtime monitoring require dedicated security modules, secure element chips, trusted platform modules and other mechanisms implemented within robust embedded architectures. Automakers are also working on standards and frameworks to facilitate security-by-design approaches for applications and over-the-air updates delivered via embedded modems and gateways. Continuous improvements and investments in this area will be important to build trust in future mobility technologies.

Market Outlook

As discussed, automotive embedded systems underpin the development of advanced technologies across electric, autonomous and connected vehicles.
