Abstract:
A method for driving a pump of a brake system, comprising:receiving by the pump, in response to a pumping request, at least one control signal, the at least one control signal being constant over at least one time interval, being specifiable, and being formed from a sum of a pulse time and interpulse period of a duty cycle; initially connecting the pump to a voltage supply for a specifiable time period; after initially connecting the pump and during the duty cycle, energizing the pump for a specifiable time period as a function of at least one condition; and stopping the duty cycle for a specifiable period of time, the at least one condition being preventively evaluated before the pump is loaded; wherein the at least one condition is an index for an increased pump load in comparison with a pump load in duty cycle mode.
