Driver information system with optimisation of fuel consumption

摘要

A driver information system with optimisation of fuel consumption by displaying the instantaneous fuel consumption as a visual marker (11) in an illustrated family of characteristic curves (14) is proposed, the family of characteristic curves showing characteristic lines of constant specific consumption as a function of the load or power and of the engine speed. In order to be able to use a uniformly designed system for different types of motor vehicles, engine-specific families of characteristic curves are called up onto the two-dimensional display panel (12) on demand. This takes place in particular by designing the family of characteristic curves as a film. <IMAGE>
