PURPOSE: To prevent a reliable brake from being released by the interruption of a power feed by providing a means for preventing the interruption of an energy feed required for operating a brake during its operation and/or for holding the operation state of the operated brake during the brake operation. CONSTITUTION: When an ASR with a brake intervention is prepared, an additional pressure rise can be obtained. When a valve 6 or 8 is activated, a control block 5a sends a signal to the inhibition input terminal 10a of an ignition lock 10, and a reliable brake is prevented from being finished by the accidental switch-off of ignition, i.e., the switch-off of the power feed to an evaluating circuit by a line 10b. The inhibition input terminal 10a regularly existing in a latest automobile prevents the switch-off of ignition while a voltage is applied to the terminal 10a. |
