Abstract
A method for operating a vehicle brake system, including activation of a electrohydraulic brake booster device when there is an actuation of a brake actuating element, so a brake pressure increase is brought about in a wheel brake cylinder, and decoupling of the wheel brake cylinder from a master brake cylinder of the brake system by closing a separating valve, it being ascertained, before the closing of the separating valve, whether a first quantity relating to an actuation speed of the actuation of the brake actuating element and/or a second quantity relating to a master brake cylinder pressure increase is within at least one specified normal value range, and, if warranted, the separating valve being closed without a delay, whereas otherwise the closing of the separating valve is delayed taking into account the second quantity and/or a third quantity relating to the brake pressure increase.
