Method for outputting at least one item of information to a driver, which information is suitable for implementing a defined and desired consumption-optimized driving style in a vehicle, in particular in a utility vehicle, wherein the vehicle has an output device for outputting the at least one item of information to the driver, and a control device which is integrated into the output device, wherein at least one action recommendation which is suitable for implementing the desired driving style is output as information, and wherein the control device comprises and evaluates the route information, traffic information and vehicle-specific characteristic variables and measurement values required to determine the information which is to be output, and outputs said information by means of the output device, having the steps of: a) defining the desired consumption-optimized driving style, wherein the definition of the driving style is carried out by activating an individual consumption-optimized driving style which is stored in the control device or by selecting a consumption-optimized driving style from a multiplicity of consumption-optimized driving styles which are stored in the control device; b) detecting a spatially bounded future situation by means of the control device, in which situation an area up to 1000 m in front of the vehicle is sensed, or detecting a chronologically bounded future situation by means of the control device, in which situation an area up to 60 driving seconds in front of the vehicle is sensed; c) determining at least one first actual parameter, wherein the fuel consumption which is to be expected for the detected future situation while maintaining the existing driving style is acquired as at least one first actual parameter, wherein only traffic-specific characteristic variables or measurement values, route information and traffic information are used to determine the first parameter; d) determining at least one second target parameter for this situation, wherein the fuel consumption, which occurs up to the end of the detected situation if the at least one item of information is completely implemented by the driver, is acquired as at least one second target parameter, wherein only vehicle-specific characteristic variables or measurement values, route information and traffic information are used to determine the second parameter; e) forming at least one difference from the first and second parameters; f) if a deviation from the second target parameter is detected outputting the at least one item of information to the driver by means of the output device in accordance with the future situation which is bounded at least spatially or chronologically. a) defining the desired consumption-optimized driving style, wherein the definition of the driving style is carried out by activating an individual consumption-optimized driving style which is stored in the control device or by selecting a consumption-optimized driving style from a multiplicity of consumption-optimized driving styles which are stored in the control device; b) detecting a spatially bounded future situation by means of the control device, in which situation an area up to 1000 m in front of the vehicle is sensed, or detecting a chronologically bounded future situation by means of the control device, in which situation an area up to 60 driving seconds in front of the vehicle is sensed; c) determining at least one first actual parameter, wherein the fuel consumption which is to be expected for the detected future situation while maintaining the existing driving style is acquired as at least one first actual parameter, wherein only traffic-specific characteristic variables or measurement values, route information and traffic information are used to determine the first parameter; d) determining at least one second target parameter for this situation, wherein the fuel consumption, which occurs up to the end of the detected situation if the at least one item of information is completely implemented by the driver, is acquired as at least one second target parameter, wherein only vehicle-specific characteristic variables or measurement values, route information and traffic information are used to determine the second parameter; e) forming at least one difference from the first and second parameters; f) if a deviation from the second target parameter is detected outputting the at least one item of information to the driver by means of the output device in accordance with the future situation which is bounded at least spatially or chronologically.
