Abstract

A technique for controlling an electrically actuable parking brake of a motor vehicle in the event of failure of a first signal indicating a speed of the motor vehicle comprises the steps of continuously closing the parking brake as long as a second signal indicating a driver request to close the parking brake is detected, and opening the parking brake, provided that the parking brake is in a partially open state, as long as an absence of the second signal is detected.
