Benefits of technology

The technical effect of this patented method involves creation of an artificially controlled environment where vehicles are driven under various conditions such as road traffic or accident scenes for better understanding how they behave during accidents on roads. This allows researchers studying these systems more easily while also improving their ability to develop new technologies based upon them. Additionally, it simplifies the process of generating vehicle states from simulations made up of different models connected together without any errors caused by differences between each other's behavioral characteristics. Overall, this technology helps identify potential issues affecting safety performance of autonomous cars (AD) system components like cameras used inside them.

Problems solved by technology

This patented describes two main challenging aspects: firstly, there're no efficient ways to check if certain parts or components within cars have been properly designed without having their impact upon other car systems; secondly, while current methods rely heavily on manual tests, they require long periods after completing production.
