Abstract

A method and system for determining an operating point of an agricultural vehicle is disclosed. The agricultural vehicle includes a ground engaging device for supporting the vehicle on the ground, a propulsion engine for driving the ground engaging device, sensors for generating sensor signals, and an evaluation unit. An input parameter is entered into the evaluation unit. The evaluation unit accesses a characteristic diagram for operating parameters of the agricultural vehicle (either by generating the characteristic diagram or accessing a previously stored characteristic diagram). The evaluation unit then determines the optimal operating point of the agricultural vehicle based on the characteristic diagram. The evaluation unit determines a current operating point based on acquired vehicle parameters, and compares the current operating point with the optimal operating point. Based on the comparison, the evaluation unit may determine the operating point of the agricultural vehicle.
