1. A motor vehicle control system for controlling a motor vehicle with a hybrid drive comprising:

  • an internal combustion engine and an electric motor,a plurality of functional components, each of the functional components comprises at least three sub-components including a strategy sub-component (8), a control sub-component (9) and an actuator sub-component (10), the functional components at least including;

    an internal combustion engine functional component (2) for controlling the internal combustion engine,a transmission functional component (3) for controlling a transmission, anda hybrid functional component (4) for controlling the electric motor and a clutch connected between the internal combustion engine and the electric motor, the strategy sub-component (8) of the hybrid functional component (4) comprises an operating status prescription module which determines a recommended value for the operating status of the hybrid drive and transmits the recommended value to the control sub-component (9) of the hybrid functional component (4), and a possible recommended value, that can be determined by the operating status prescription module, is a preselected hybrid driving condition, and, if the operating status prescription module of the strategy sub-component (8) of the hybrid functional component (4) transmits the preselected hybrid driving condition, as the recommended value, to the control sub-component (9) of the hybrid functional component (4), then the strategy sub-component (8) of the hybrid functional component (4) prescribes a change from an electric driving operating status to a hybrid driving operating status, and the control sub-component (9) of the hybrid functional component (4) determines a time when, and a manner in which, the change from the electric driving operating status to the hybrid driving operating status occurs.
