Abstract

A control system for controlling a vehicle with a hybrid drive comprising an internal combustion engine and an electric motor and a plurality of functional components each divided into strategy, control and actuator sub-components. The functional components include engine, transmission and hybrid functional components. The strategy sub-component of the hybrid functional component 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. The 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 transmits the preselected hybrid driving condition, as the recommended value, to the control sub-component, then the strategy sub-component prescribes a change from electric to hybrid driving, while the control sub-component determines when change occurs.
