A parking brake, particularly for a vehicle, includes a brake piston, supported to be movable along a longitudinal axis between a braking position and an open position, by which a brake disk is immobilizable by applying a braking force, when the brake piston is in the braking position, a drive unit for moving the brake piston along the longitudinal axis, and a toggle lever interacting with the brake piston and having at least first and second legs. The first and second legs are connected rotatably with a joint element and are actuatable by the drive unit, such that the toggle lever provides the braking force and applies it to the brake piston. An immobilizing device having such a parking brake, as well as a vehicle having the immobilizing device, and a method for immobilizing a vehicle by such an immobilizing device are also provided.

A method is for closing a solenoid valve in which the solenoid valve is charged with a first current value that results in a first closing of the solenoid valve, and the solenoid valve is subsequently charged with a second current value that results in a renewed partial opening of the solenoid valve, and the solenoid valve is subsequently charged with a third current value that results in a second closing of the solenoid valve, the third current value being selected such that the second closing takes place with a higher closing speed of the solenoid valve than does the first closing.
