A data bus connects the individual control units and enables them to exchange data.

The signal from a sensor is passed on to the nearest control unit, processed by it and placed on the CAN data bus.

Each control unit that is connected to the CAN data bus can read this signal and use it to calculate an input to control an actuator.
