Abstract
A method of controlling a pump in a brake system of a motor vehicle, in particular an electrohydraulic brake system, is described, where the pump can be controlled by a pump motor either uncycled or continuously and cycled, where the period of uncycled control and/or an initial pulse-pulse pause ratio at the start of cycled control can be varied as a function of a voltage applied to the pump motor before and/or at the start of and/or during uncycled control and/or as a function of an on-board voltage of the motor vehicle determined before and/or at the start of and/or during uncycled control.
