Special communication modules are responsible for exchanging information between ECUs via a bus system such as CAN, LIN, FlexRay, MOST or Ethernet. The Vector communication modules are standard software components that are based on generic code. The ECU developer configures them individually to obtain a solution customized to his specific application.
