METHOD AND DEVICE FOR ACTIVATING AT LEAST ONE ENERGY MANAGEMENT FUNCTION IN A VEHICLE

摘要

The invention relates to a method for activating at least one energy management function (12.1 to 12.4) in a vehicle on the basis of the current state of a battery (40), wherein at least one parameter for determining the current state of the battery (40) is detected and/or determined, wherein the validity of the values of the at least one detected and/or determined parameter is represented by a state variable (24), which after a reset operation and/or battery change is set to a basic state and on the basis of predetermined criteria of the basic state is changed to a set state. A main energy manager (22) only activates the at least one energy management function (12.1 to 12.4) when the state variable (24) has the set state and the at least one detected and/or determined parameter reaches a corresponding main limiting value and/or meets a corresponding main condition. The invention also relates to an associated device, to a computer program product and to a data processing program for carrying out the method for activating at least one energy management function in a vehicle. According to the invention an emergency energy manager (26) is provided which only activates the at least one energy management function (12.1 to 12.4) when the state variable (24) has the basic state and the at least one detected and/or determined parameter reaches a corresponding emergency limiting value and/or meets a corresponding emergency condition, wherein the emergency limiting values are higher than the main limiting values and/or the emergency conditions are predetermined to be simpler to check than the main conditions.
