Method for switching consumer on or off
First Claim
1. A method for turning on or off electrical loads in a vehicle on-board electrical system, by means of switch elements which are triggerable in such a way by a controller that the electrical loads are turned on or off taking switching priorities into account, characterized in that the electrical loads are grouped in classes of different switching priorities and the grouping of the electrical loads is done based on a normal state, the grouping of the electrical loads in classes with the switching priorities is variable dynamically during operation as a function of the operating state of the electrical loads, and the electrical loads can change their class belonging during the operation, wherein the switching of loads is performed by a control unit (SG) of a vehicle, and the loads are electrical and optionally also mechanical loads whose switching priority is varied by the control unit in accordance with the specifiable conditions, and wherein in the choice of priorities of the loads, drive requirements are taken into account, so that a driver-dependent turn-on or turn-off of the loads takes place.

Abstract
A method for turning various classes of loads on and off by means of switch elements in the context of energy management performed by a control unit, particularly in a motor vehicle, is described, in which the triggering of the switch elements is done such that the selected priorities for triggering the switch elements can be varied during operation, that is, dynamically. This enables an adaptation of the switching priorities during ongoing operation as a function of the operating state. The turn-off of loads is done by varying the switching priority in such a way that the perceptibility of the operating states is suppressed as much as possible, and the priorities can also be varied in accordance with person-specific criteria.
