1. An electrical infrastructure system for a vehicle, the vehicle having at least one functional unit for the vehicle, the system comprising:

  • a plurality of electronic control units (ECU) for one or several functional units for the vehicle, and a network connecting the ECUs;

    the infrastructure system is configured to implement a state map comprising various operational states of the vehicle, one or several predetermined transition conditions connecting these operational states such that a transition from one operational state of the operational states to another operational state of the generated states depends on whether at least one predetermined transition condition of the predetermined transition conditions is satisfied;

    the infrastructure system is configured to receive at least one input signal to at least one ECU, the input signal comprising a parameter value that represents an event, and the at least one ECU is configured to process the input signal, with the aid of the predetermined transition conditions, to determine a current operational state of the operational states for the vehicle based on the result of the processing, and the at least one ECU is configured to make the current operational state that has been determined available on the network;

    wherein the operational states for the vehicle have different priorities, from a lowest priority to a highest priority, and in case a conflict arises as to which operational state is to be determined as the current operational state, an operational state with a higher priority is preferred to one with a lower priority; and

    each of the ECUs comprises a state module that comprises a unique set of state rules for each one of the operational states, the state module is configured to identify the current operational state of the vehicle based solely on the state rules, and to apply at the ECU the state rules that are associated with the operational state that has been identified,wherein the state rules comprise control parameters for the ECU.
