VIL FOR ADAS DEVELOPMENT
James Hayes outlines how vehicle development can be accelerated by using vehicle-in-the-loop testing
Y
ou may have come across the term ‘in-the-loop’ before, as it is commonly used in automotive development
together with different subjects such as model-, software- and hardware- to create a brand-new sentence. But what does that phrase actually mean? An English dictionary will tell you that if someone is the ‘in-the-loop’, they are part of a group of people who make
decisions about important things, or they know about these decisions. This also applies in automotive terms, where, by putting a model, software, hardware or even a vehicle in-the-loop together with other subsystems, we can understand how it behaves under various scenarios and conditions. In a traditional V-cycle development
process, the in-the-loop would follow a sequential path starting with models,
progressing through various steps of software- and hardware-in-the-loops up to a vehicle that is then driven on the road. The V-cycle has proven itself over many decades but is now being challenged by alternative development processes, such as agile development, which, by nature, is more gradual and is usually visualised as circular. The in- the-loop exists in this type of process as well, but then also in parallel.
