Method for organizing and executing a plurality of services in particular on board a motor vehicle

A method for executing a plurality of functionalities, comprising:

• a) defining a plurality of cases of use for each of which, within a context, a demand invokes a reaction that implements one of said functionalities;
• b) selectively activating the reaction upon detection of transmission of the demand within the context;
• c) defining, for each functionality implemented by a system of hardware and software components, a plurality of cases of use of the functionality, each case of use being composed of:
• a context corresponding to conditions of application of the case of use, in a form of computerized parameters or of physical states of hardware components,
• a user's demand, and
• a response of the system to the demand, and
• wherein the system carries out the response upon detection of the transmission of the demand within the context;
• d) for each functionality, automating execution of the functionality with an automatic controller of the system of hardware and software components, transitions of the automatic controller representing demands of the cases of use and states representing execution of responses of the cases of use, and
• e) identifying the context of the automatic controller that each represent a set of values of vehicle parameters that are not affected by the functionality but that affect the functionality.
