Abstract: A steering system for a vehicle has at least one data processing device, a track following system for determining a driving route and enabling the vehicle to be steered automatically via the at least one data processing device, the track following system including at least one first driving route detection system and at least one further driving route detection system, the driving route detection systems being coupled via the at least one data processing device such that it is possible to switch between the driving route detection systems.

Abstract: An electronic machine management system for initiating switching and actuating procedures with positional accuracy in agricultural working machines, has a geographic module for determining a current position, and based on information regarding positions of critical field data, quantities to be applied, field boundaries, work areas and/or areas to be avoided, and a machine-specific module that contains machine-specific functionalities, the modules being configured so that the geographic modules supplying the machine-specific module with geographic information in real time, and, based on the geographic information in real time, the machine-specific module generating machine-specific switching and actuating procedures in real time and sending signals relevant thereto to particular switching and actuating elements.
