Control device and method for operating an electromechanical brake booster of a brake system configured to execute anti-lock control actions

A control device for an electromechanical brake booster of a brake system configured to execute anti-lock control actions, comprising:

• an electronic device for determining a setpoint variable regarding a setpoint brake pressure to be produced by the electromechanical brake booster, at least in view of at least one supplied sensor signal regarding a differential travel of a driver braking force transmission component adjustable via manipulation of a brake actuating element of the brake system and a booster force transmission component adjustable by the electromechanical brake booster, wherein:
• the electronic device controls the electromechanical brake booster in view of the determined setpoint variable;
• during at least an anti-lock control action executed in the brake system, the electronic device ascertains if the differential travel lies outside of a specified normal value range,
• if at least the differential travel lies outside of the specified normal value range, the electronic device determines a correction variable for the setpoint variable in view of at least a difference of the determined setpoint variable and a supplied actual variable regarding an actual pressure present in at least part of a volume of the brake system, and
• the electronic device controls the electromechanical brake booster in view of the determined correction variable.
