Data Bus

The data bus facilitates the rapid exchange of all manner of information between the vehicle’s sensors, actuators and control units, etc. By exchanging data digitally, the data bus ensures that the information from one sensor can be relayed to and processed by multiple different control units. The risk of a complete system failure is reduced considerably. The rain sensor is one example of how the system works:
the signal “It is raining” from this sensor prompts the data bus to activate the windscreen wipers, the brake disc wiper function, the ventilation for the windscreen, as well as the headlights.
