Method For Energy Management
First Claim
1. A method for energy management, in particular for the energy management of the on-board electrical system of a vehicle with a generator, at least one energy store and consumers which can be divided up into a plurality of classes, with the following steps:
- determination of the condition of the generator and energy stores (s) (S1),definition of the energy available in a subsequent time interval Δ
t from the determined condition data of the generator and energy store(s) (S4),reception of activation requests from consumers for the subsequent time interval Δ
t (S5),determination of the energy required in the subsequent time interval Δ
t on the basis of activation requests (S6),checking whether the required energy is greater than the available energy (S7),if the available energy is sufficient,fulfillment of all activation requests of the consumers in the subsequent time interval (S8), orif the available energy is not sufficient, selection of the consumer(s) to be activated in the subsequent time interval Δ
t according to the energy available and a priority and tolerance time (TL) of the corresponding consumers (S9).

Abstract
The invention relates to a method for energy management, whereby large variations in current draw in the loom are reduced, in particular current draw spikes, caused by very high making currents for electric actuators and solenoid valves, which are more evenly distributed over time. The above is achieved, by means of a predictive working of said method for energy management, by determination of both energy available in the subsequent period and the energy requirement, based on switch-on requests and selects users for switching on, according to the priority thereof and an actual tolerance time, within which a user must be switched on at the latest, following the declaration of a switching-on request for the same. The tolerance time is continuously updated.
