Energy management method for a vehicle and energy management device
First Claim
1. An energy management method for a vehicle which comprises an energy store and a plurality of consumers, the method comprising:
- detecting the energy reserve in the energy store and calculating a predicted actual range of the vehicle;
generating and displaying a graphic object which visualizes the predicted actual range;
detecting a user input with which a setpoint range is set in that the graphic object is changed by an input device;
calculating a difference between the setpoint range and the predicted actual range;
calculating changes in state of at least one subset of the consumers based on the difference between the setpoint range and the predicted actual range so that the setpoint range is achieved; and
outputting the calculated changes in state as a proposal,wherein the predicted actual range is determined based on data relating to a route of the vehicle having route sections on which energy consumption is relatively high or energy consumption is relatively low.

Abstract
An energy management method for a vehicle having an energy store and consumers, in which the energy reserve in the energy store is detected and a predicted actual range of the vehicle is calculated, a graphic object which visualizes the predicted actual range is generated and displayed, a user input is detected with which a setpoint range is set in that the graphic object is changed by an input device, after the setting of the setpoint range, on the basis of the difference between the setpoint range and the predicted actual range it is calculated by which changes in state of at least one subset of the consumers the setpoint range can be achieved, and the calculated changes in state are output as a proposal. Also disclosed is an energy management device for carrying out this energy management method.

11. An energy management device for a vehicle which comprises an energy store and a plurality of consumers, the energy management device comprising:
-
a sensor device for detecting the energy reserve in the energy store of the vehicle, a computing device, coupled to the sensor device, for calculating the predicted actual range of the vehicle; a display device, coupled to the computing device, for generating and displaying a graphic object which visualizes the predicted actual range; and an input device for detecting a user input, with which a setpoint range is set by changing the graphic object, wherein, after the setting of the setpoint range, the computing device calculates the difference between the setpoint range and the predicted actual range and calculates changes in state of at least one subset of the consumers such that the setpoint range can be achieved, and wherein the calculated changes in state are output as a proposal by the display device, wherein the predicted actual range is determined based on data relating to a route of the vehicle having route sections on which energy consumption is relatively high or energy consumption is relatively low. - View Dependent Claims (12, 13, 14, 15, 16)
