Abstract
A device monitors an automatic braking process by using a fault-detecting, operational testing method which takes place via an automatic braking process lasting only briefly, typically about 50 ms. The method is initiated by a test control device and can take place during different vehicle states. If, for example, current through a solenoid valve does not lie within specific acceptable limit values or pedal travel which results from the actuation is not determined at the brake pedal, the device concludes that an operational fault has occurred
