The software-defined vehicle (SDV) combines cutting-edge technology in Automotive hardware and software. Learn more about the SDV & how it’s changing test.
A software-defined vehicle (SDV) relies on software to function, with sensors, communication networks, high performance electronic control units (ECUs), and artificial intelligence/machine learning algorithms working alongside traditional electromechanical hardware like the engine, electric motors and transmission.
SDV-enabled features include Advanced Driver Assistance Systems (ADAS), digital cockpits, infotainment interfaces, and over-the-air updates that can be downloaded to improve functionality or performance.
Software-defined vehicles offer many benefits to consumers, but present new challenges for the automotive industry. Their complexity requires extensive design and testing to meet strict requirements and expectations for safety and reliability. Let’s take an in-depth look at SDVs and how they’re changing automotive test.
For most of their existence, automobiles were solely mechanical in nature. Today’s new cars resemble a device on wheels with sensors, cameras, processors, in-vehicle systems, and wireless connections to external networks. The software-defined vehicle includes the following core components:
The marriage of automotive software and hardware has many potential benefits for drivers:
Automotive test has been growing from testing electromechanical components into software validation embedded into ECUs and with the introduction of the SDV this evolution has been accelerated further. The software-defined vehicle increases demands on engineers by adding ECUs with semiconductors, wireless technology, multiple sensors, automotive operating systems, and more to an already complex machine.
Compounding the challenge are automotive test methodologies rooted in a legacy design and manufacturing process, prescribed by the V-diagram. These approaches tend to be inflexible, slow, and therefore poorly suited for accelerated software and hardware test and validation. However, it’s not possible to simply adopt electronics test processes as automotive companies must comply with strict government safety regulations.
The pace of change and the pressure to be first-to-market make adaptability and the introduction of agile development including Continous Integration and Continous Deployment (CI/CD) key in evaluating and evolving SDV systems. NI has long had a presence in transportation and semiconductor test with software-defined, modular hardware systems that offer and help our customers to quickly create custom systems, optimized for their unique application needs. From the very beginning NI’s systems and solutions have always been software-define by nature, which makes them the perfect counterpart in testing the SDV in particular for evolving with them along their whole development and deployment life cycle.
For example, NI TestStand software allows engineers to develop, deploy, and debug automated production test systems for ECUs. VeriStand is used for hardware-in-the-loop (HIL) testing, so engineers can see how ECUs respond when integrated with other systems based on simulations and models to shift testing and validation to earlier stages.
Our modular hardware, such as PXI instruments, can be easily added or removed from a test or validation system, as application requirements evolve – not only by NI engineers, but by the end users themselves. Out-of-the-box solutions like the NI ECU Test System (ECUTS) merge software, hardware, and services to simplify the ECU production test process.
NI supports each of these aspects and more of SDV development and test with a commitment to OEMs and tier 1 suppliers demonstrated over many years in the automotive and electronics industries.
The software-defined vehicle is revolutionizing transportation. Consumers expect ongoing innovative features in their cars and not just once when they are adding the initial purchase. and new testing tools and methodologies are key to making sure the next generation of vehicles offers cutting-edge technologies in a safe, reliable automobile – and NI is partnering with OEMs and Suppliers to make test their strategic advantage in achieving their ambitious engineering goals.
