Method for controlling power flow
First Claim
1. A method for controlling energy sources or energy sinks on an energy accumulator in a motor vehicle, the method comprising the steps of:
- measuring at least one parameter which characterizes the state of charge of the energy accumulator,transmitting the parameter which characterizes the state of charge of the energy accumulator to a control unit,prioritizing data from a plurality of modules by a data mask;
adapting and filtering the data based at least in part on data formats;
generating by the control unit at least one control signal as a function of the parameter which is characteristic of the state of charge of the energy accumulator, which control signal controls energy sinks or energy sources which are connected directly or indirectly to the energy accumulator, in terms of the power which they consume from the energy accumulator or the power which they emit to the energy accumulator, andcalculating by the control unit the energy consumption of energy sinks on a planned route in advance, wherein the data is weighted to minimize processing time.

Abstract
A method for controlling power sources or energy sinks on an energy accumulator, in particular for a motor vehicle, is disclosed. Conventional systems for power supply to the motor vehicle modules are often excessively used, in particular in utility vehicles when an optimal availability is required. The present method includes measuring parameters characterizing the charge of the accumulator, and transmitting the results of a measurement to a control unit and in generating control signals for the energy sinks or the power sources by a control unit. The method makes it possible to eliminate a frequent cause of a low availability in motor vehicles.
