Method for re-tensioning an electromechanical parking brake device of a vehicle

A method for re-tensioning an electromechanical parking brake device of a vehicle, wherein the electromechanical parking brake device includes a first electromechanical brake and a second electromechanical brake, each including:

• a brake disk, at least one brake pad, an electromechanical actuator configured to press the at least one brake pad against the brake disk to generate a braking effect, and a locking device configured to lock the at least one brake pad when pressed against the brake disk, wherein the method comprises the following steps:
• ascertaining whether re-tensioning of the first electromechanical brake is necessary;
• performing a diagnosis to check a re-tensioning functionality of the parking brake device, when re-tensioning is necessary;
• and
• re-tensioning the first electromechanical brake only when no fault is recognized during the diagnosis, wherein the re-tensioning includes:
• controlling the locking device of the first electromechanical brake to release the locking,
• pressing the at least one brake pad of the first electromechanical brake against the brake disk of the first electromechanical brake with a specified force using the electromechanical actuator of the first electromechanical brake, and
• controlling the locking device of the first electromechanical brake to lock the at least one brake pad of the first electromechanical brake when pressed against the brake disk of the first electromechanical brake.
