Claim 17:
18. A control circuit, which is developed and intended for use in a motor vehicle, comprising:
a first line, which is connected to a first phase and/or to a first electrical connection of an electric drive of a drive arrangement of a brake system of a motor vehicle, wherein the drive arrangement is designed to apply and/or boost a brake force;
a second line, which is connected to a second phase and/or to a second electrical connection of the electric drive of the drive arrangement;
a third line, which is connected to a third phase and/or to a third electrical connection of the electric drive of the drive arrangement;
a controllable switch, which is designed to disconnect the first line, the second line, and the third line in an open state and to connect them to one another in a closed state; and
a switch control module, which is developed and intended to control the switching states of the controllable switch, wherein the switch is opened in a first control state and the switch is closed in a second control state, wherein the switch control module is furthermore developed and intended to switch from the first control state to the second control state as soon as the electric drive has been disconnected from a supply source and/or a voltage drop and/or current drop has taken place.
