Patent number: 8397879Abstract: A parking brake having an actuator, wherein the actuator is driven by a direct current motor which can be operated in two directions. The actuator moves, via a self-locking gear mechanism of the actuator, at least one brake shoe for applying or releasing the parking brake in the direction of a rotary element or away therefrom. A control unit for performing open-loop or closed-loop control of the movement of the direct current motor is also provided. The parking brake is designed such that, when the parking brake is applied or released, an application point of the brake shoes against the rotary element is generally overshot.Type: GrantFiled: October 23, 2008Date of Patent: March 19, 2013Assignee: Continental Teves AG & Co. oHGInventors: Christof Maron, Marcus Schumann, Faouzi Attallah, Heinz-Anton Schneider

Patent number: 8301331Abstract: A method for the calibration or diagnosis of a motor vehicle brake system having a cyclically operated pump. At least one parameter (URPOff), representing the electromotor force of the reference pump, is repeatedly ascertained during operation of a reference pump under defined guidelines. A statistical characteristic variable (URPOff) is derived from the values of parameter (URPOff) ascertained for the reference pump. Parameter (UBPOff) is ascertained under a corresponding guideline during operation of an operating pump. Corresponding statistical characteristic variable (UBPOff) is derived from the values of parameter (UBPOff) ascertained for the operating pump. At least one ratio number is calculated as a measure of the deviation of the operating behavior of the operating pump from the operating behavior of the reference pump from the characteristic variable (URPOff) calculated for the reference pump and the characteristic variable (UBPOff) calculated for the operating pump.Type: GrantFiled: October 22, 2008Date of Patent: October 30, 2012Assignee: Continental Teves AG & Co. oHGInventors: Faouzi Attallah, Tobias Scheller, Tom Robert

Patent number: 8205948Abstract: A method of determining an initial pressure prevailing between a master brake cylinder and an inlet valve of a wheel brake cylinder of a motor vehicle determines the initial pressure taking into consideration the variation of a voltage of a PWMoperated motor of a pump, which is used for the return delivery of brake fluid from a low-pressure accumulator into the master brake cylinder. Several characteristic quantities of the voltage variation are measured and converted to respective initial pressure values. The characteristic quantities or the initial pressure values determined therefrom are filtered or conditioned in the event of lack in quality or reliability of the measured characteristic quantities. The respective initial pressure values of similar size are averaged, and the averaged initial pressure values are temporally averaged in order to dampen fluctuations.Type: GrantFiled: August 28, 2006Date of Patent: June 26, 2012Assignee: Continental Teves AG & Co., OHGInventors: Faouzi Attallah, Rudiger Majlo, Guntjof Magel, Lukas Kroh, Frank Sikorski, Andreas Kohl, Jochen Muller

Patent number: 7992691Abstract: A parking brake having an actuator, wherein the actuator is driven with a direct current motor which can be operated in two directions and which moves a piston of the actuator and, via a self-locking gear mechanism of the actuator, at least one brake shoe for applying or releasing the parking brake. A control unit for performing open-loop or closed-loop control of the movement of the direct current motor is also provided. During open-loop or closed-loop control of the movement of the direct current motor for applying and/or releasing the parking brake, the control unit takes into account a hydraulic admission pressure which is currently present at the piston if the brake is applied or was present at the piston if the brake has been released when it had previously been applied. A corresponding method for operating such a parking brake is also disclosed.Type: GrantFiled: October 23, 2008Date of Patent: August 9, 2011Assignee: Continental Teves AG & Co. oHGInventors: Christof Maron, Marcus Schumann, Faouzi Attallah, Heinz-Anton Schneider

Publication number: 20080231108Abstract: A method of determining an initial pressure which prevails between a master brake cylinder and an inlet valve of a wheel brake cylinder of a motor vehicle brake system. It determines the initial pressure taking into consideration the variation of a follow-up voltage of a clock-operated motor of a pump, which is used for the return delivery of brake fluid from a low-pressure accumulator into the master brake cylinder. Several characteristic quantities of the voltage variation are measured and in each case taken into account to determine an initial pressure value, and the quality and/or reliability of the measured characteristic quantities is evaluated.
