Abstract

Control and navigation system for a motor vehicle that can be connected to a traffic guidance system and has means for control and regulation of the vehicle-driving behavior, whereby control and regulation is automatic or semi-automatic. In contrast to existing systems, where a navigation system generates instructions or advice for a driver to follow, the inventive system operates automatically or semi- automatically, so that after a driver has input chosen parameters the system acts accordingly. E.g. a driver may want to optimize fuel use in which case the route chosen will be the shortest, while vehicle behavior will be controlled to maximize fuel usage.
