A dispersed control system for use in a vehicle. The dispersed control system includes a plurality of electrical control units that exchange data via a communication system. The system includes at least two power sources that are independent of each other and that supply each of the plurality of electrical control units with a voltage. The communication system includes at least two channels, and bus drivers are provided in each electrical control unit so that each channel is supplied with a voltage from a different one of the at least two power sources.
