siliconindia | | MAY 20248In a fast-changing car world, Software-Defined Vehicles are leading the charge into a new future. Unlike traditional cars that rely heavily on hardware, these new vehicles use clever software to run, do cool things, and bring out new features. This change isn't just about tech ­ it means safer rides, comfier trips, and super-connectivity like never before. Imagine cars that get better over time, just like your favorite app updates. It's a revolution where cars grow with us, opening up endless possibilities on the road ahead.The Rise of Software-Defined VehiclesThe next of the automotive sector is no longer solely determined by traditional mechanical engineering practices. Analysts observe a growing intertwining of digital technology trends, such as generative artificial intelligence (AI), quantum computing, and semiconductor advancements, with both passenger and commercial mobility. This transformation aligns with a cultural shift in how automakers conduct their business.Historically, automotive firms have focused on hardware, leaving software expertise largely to tech companies. However, in the changing scenery, major car manufacturers face an essential decision: whether to play a leading role in the emerging automotive software ecosystem. To accomplish this, they must select through the noise of the current market turbulence surrounding Software-Defined Vehicles (SDV), locate sincerely important business models, craft a well-defined transformation strategy to shift from the current tumultuous phase to a productive one, and above all, embark on their transformation journey without delay.Sai Sridhar, Associate Director - Elektrobit India says, "The software-defined vehicle trend is centered around speeding up time to market for software innovation".A Paradigm Shift in MobilityThe impact of software-defined vehicles cannot be overstated. They have the potential to benefit both individuals and society as a whole, leading to significant changes in the automotive industry. With autonomous driving (AD) functions, SDVs could prevent up to 90 Percent of traffic-related deaths and offer newfound independence to disabled individuals who can now travel by car on their own. As AD takes over driving tasks, commuters can use their time for other activities like meal preparation, vacation planning, or catching up on sports highlights. Unlike traditional vehicles, SDVs will receive regular software updates, allowing for continuous management, maintenance, and improvement. This means that innovation will be ongoing, eliminating the need to wait for a new car purchase to access new features.The Layers of Software-Defined VehiclesThe software and hardware setup of a Software-Defined Vehicle is highly intricate, often consisting of numerous interconnected software systems spread across up to a hundred electronic control units (ECUs). While some manufacturers aim to simplify this by reducing the number of ECUs and relying on a central, powerful computer, the architecture of these vehicles can generally be divided into four main layers:User Applications: User applications encompass software and services that directly engage with drivers and passengers. These can range from entertainment systems to vehicle controls and digital dashboards.Instrumentation: The instrumentation layer pertains to systems concerning a vehicle's functionality that typically operate without direct input from the driver. Examples include Advanced Driver Assistance Systems (ADAS) and intricate controllers.Embedded OS: At the heart of the Software-Defined Vehicle lies the embedded operating system, responsible for managing critical functions and facilitating general operations. Built on microkernel architecture, these systems allow for modular addition or removal of software capabilities.EDITORIAL EXCLUSIVEARE SOFTWARE-DEFINED VEHICLES THE FUTURE OF DRIVING?
