Abstract
In a method for monitoring the operation of a vacuum pump in a brake system, the vacuum pump is operated between an activation pressure and a deactivation pressure to generate a vacuum, the evacuation period between the activation pressure and the deactivation pressure being measured and compared with a reference period. An error signal is generated if the evacuation period exceeds the reference period.
