The complexity of vehicles and their technical possibilities is increasing. In the past, development engineers could develop parts of a car in silos, largely independently of each other. Today, due to the large amounts of software, everything is connected to everything else, be it infotainment systems, air conditioning, engine control, or brakes. There are many dependencies within the car and with external backend systems. This complexity requires new procedural models in development.
More and more car manufacturers are using software to create digital twins of their vehicles. Data from development, vehicle components, or later vehicle use flow into the virtual representation. Vehicle development in particular benefits from digital twins, as they allow the testing of developments of complex vehicle systems on digitally simulated components.
Until now, vehicle parts or control unit software have first been developed and then given a test drive. The test results are then incorporated into improvements. This process takes months, and the car manufacturers have to repeat these tests several times until the desired or required driving characteristics are achieved. Digital twins, on the other hand, simulate the properties of vehicle components in certain driving situations and can thus accelerate development enormously.
