The BYTEFLIGHT bus system has a star-shaped structure. The individual satellites (= control modules with/without sensors) are interconnected across a star connector by means of fiber-optic cables. The star connector in the BYTEFLIGHT bus system is the Safety and Gateway Module. There is a transmission and a reception module (transmitter and receiver) as a unit in each satellite for connecting to the BYTEFLIGHT bus. The unit has an integrated transmit and receive diode.
In the event of a rollover, the roll bar extends, locks and thus secures the survival space for the vehicle occupants. There is a roll bar behind each of the rear seats. In the event of an accident with rollover, the sensor in the vehicle center satellite detects the vibration and sends the information ”activate roll bar” to the Safety and Gateway Module. The vehicle center control module is connected to the Safety and Gateway Module across a serial cable (and fiber-optic cable). The information ”activate roll bar” is forwarded across the serial cable. In addition, the other satellites determine the severity of the accident. With the information ”activate roll bar” matching ”severity of the accident”, the roll bars are triggered.
There are two possibilities to activate the roll bar:
All work on the airbags must be carried out with the battery disconnected!
Connect and disconnect all BYTEFLIGHT control modules, sensors and generators only with the battery disconnected!
If a fiber-optic cable on the BYTEFLIGHT bus has to be repaired, it must be borne in mind that there may only be one join in a fiber-optic cable. If there is already a join due to a door connector, the fiber-optic cable must not be repaired. In the case of a defect, the fiber-optic cable must be replaced!
