Patent number: 8063590Abstract: Both a method and a use by this method of an apparatus for detecting blocking of a direct current motor (10), in particular a direct current motor (10) for a blower of a motor vehicle, is presented. The direct current motor (10) is deactivated by a computer unit (20) with the aid of a switching means (18) for a defined time period (Toff). Within the defined time period (Toff), at least one subsequent time (ta, tb), an induced voltage (U) of the direct current motor (10) is measured and forwarded to the computer unit (20). The direct current motor (10) remains deactivated if the induced voltage (U) undershoots a predetermined threshold value (Uth), or the direct current motor (10) is reactivated if the induced voltage (U) of the direct current motor (10) does not undershoot the predetermined threshold value (Uth).Type: GrantFiled: June 1, 2005Date of Patent: November 22, 2011Assignee: Robert Bosch GmbHInventors: Norbert Knab, Nikolas Haberl, Frank Fischer, Joerg Eichhorn
