Abstract
An electrically actuatable parking brake for an electrically actuator-driven motor vehicle wheel brake comprises a form-fitting locking element which is translationally displaceable for form-fittingly locking or releasing a brake actuating device to enable re-tensioning. An electric linear actuating device, together with an associated locking element, makes it possible, under the control of a microprocessor, as required, in conjunction with the electric actuator, to perform re-tensioning, without restricting the secure stationary braking of a form-fittingly secured parking brake engagement.
Claims19
A microprocessor-controlled parking brake actuation method comprising:
- engaging a translational alternately movable locking element and a counter-component of a brake actuating device on the basis of a parking brake locking position for a parking brake locking function of a motor vehicle wheel brake, or for release on the basis of a parking brake release position;
- and
- defining a displacement of the locking element with a linear actuating device assigned to the locking element, wherein the locking element cooperates in a displaceable manner with the linear actuating device such that, on the basis of a set partial parking brake position, the locking element of the brake actuating device enables re-tensioning without eliminating the parking brake engagement.
