In brief
The collected signals are used to model the environment.
Useful to know
The ADAS integration platform from Bosch is an automotive computer for assistive and automated functions. It collects and processes data from various sensors and builds a model of the environment for the follow-up. [1]
It is the computing layer other than the camera or radar as a physical sensor. The larger number of sensors is not sufficient without proper processing and integration. When comparing equipment, watch the final set of functions and their limitations. The mere presence of a powerful computer does not turn any car into an autonomous one and does not automatically determine the permitted use.
