20120205202 | METHOD FOR SETTING THE CLAMPING FORCE OF A HYDRAULICALLY SUPPORTED ELECTRIC MOTOR-DRIVEN PARKING BRAKE - A method for setting the clamping force acting on a wheel brake, a part of the clamping force being provided using an electromechanical brake device and simultaneously another part of the clamping force being provided using a hydraulic brake device. During an application procedure, the power consumption of the electric motor-driven brake device is regulated to an essentially constant value in an operating phase (phase 4), in which both brake devices simultaneously exert force, so as to set the clamping force of the parking brake very precisely. | 08-16-2012 |
20120245816 | METHOD FOR REDUCING THE CLAMPING FORCE APPLIED BY A PARKING BRAKE - In a method for reducing the clamping force applied by a parking brake, which may be generated at least partially by an electromechanical brake device having an electric brake motor and supplemented if necessary by a hydraulic brake device, a signal is generated for actuating the hydraulic brake device for the case that it is not possible for the brake motor to be released for reducing the clamping force. | 09-27-2012 |
20130001027 | Method for operating a parking brake of a vehicle - A method for operating a parking brake of a vehicle, in particular of a motor vehicle, which parking brake operates in the superposition mode, the brake force of the parking brake being applicable by two different force-generating actuators mutually supporting one another in the superposition mode. It is provided that the force-generating, in particular pressure-generating, actuator is activated for support even before the superposition. | 01-03-2013 |
20130190970 | Method for securing an electrically operated parking brake - A method for securing an electrically operated parking brake, characterized by the following steps: monitoring an operating variable which is relevant for the proper functioning of the parking brake; ascertaining/determining whether the operating variable exceeds a predefined threshold value; and prompting the driver to carry out a certain action as a function of the value of the operating variable, the action including the engagement of the gear or the operation of the foot service brake. Also described is a control unit for carrying out the described method. | 07-25-2013 |
20130226423 | method for providing the clamping force applied by a parking brake - In a method for providing the clamping force generated by a parking brake, the roadway incline is measured and in the case that the roadway incline exceeds a threshold value, a reengagement process is carried out after a defined time period has elapsed. | 08-29-2013 |
20130231839 | Method for determining a failure in a service or parking brake in a vehicle, regulating or control unit for carrying out the method, and parking brake having such a regulating or control unit - In a method for determining a failure in a service or parking brake having an electromotive and a hydraulic brake device for generating a clamping force, an error is detected in the hydraulic brake device if an electromotive characteristic of the electric brake motor is outside an admissible value range. | 09-05-2013 |
20130345023 | METHOD FOR SECURING A VEHICLE ON A ROLLER DYNAMOMETER - A method for securing a vehicle, whose wheels of one axle are on a dynamometer, against being unintentionally pushed out of the dynamometer during an inspection of the parking brake. In order to avoid endangerment of people who are in the surroundings of the vehicle, it is proposed to ascertain with the aid of a sensor system whether the vehicle is located on a dynamometer and, if this has been determined, to automatically generate a braking torque at a wheel brake of at least one wheel, which is located outside the dynamometer, after a control element of the parking brake has been operated. | 12-26-2013 |
20140172259 | METHOD FOR OPERATING A PARKING BRAKE HAVING AN ELECTROMOTIVELY DRIVEN PARKING BRAKE MECHANISM - A method for operating a parking brake with an electromotively driven parking brake mechanism includes applying the parking brake by the electric motor, switching off the electric motor in the state in which the parking brake is applied, switching on the electric motor after a prespecified time and reapplying the parking brake mechanism in the brake application direction. During the brake reapplication operation, an electrical variable of the electric motor is determined and compared with a reference value. The brake reapplication process is continued or terminated depending on whether the electrical variable, or a variable derived therefrom, is smaller or greater than the reference value. | 06-19-2014 |
20140180535 | METHOD FOR MONITORING THE FUNCTION OF A PARKING BRAKE IN A VEHICLE - In a method for monitoring the function of the parking brake in a vehicle, the movement state of the vehicle is monitored after the parking brake has been operated and a warning signal is generated in the case of a vehicle movement. | 06-26-2014 |
20140214296 | AUTOMATIC PARKING BRAKE WITH OPTIMIZED RE-TENSIONING METHOD - A method for re-tensioning an automatic parking brake by an electric motor includes carrying out a re-tensioning process after a predefined time period after the tensioning of the parking brake. The parking brake is driven in the tensioning direction by the electric motor to determine the travel carried out by the parking brake in the tensioning direction and the clamping force exerted by the parking brake during the re-tensioning. The method further includes carrying out a further re-tensioning process after a predefined time if the travel of the parking brake is less than a predefined threshold value and the clamping force in the parking brake is less than a second threshold value. If the travel of the parking brake is greater than a third threshold value or the clamping force exerted by the parking brake is greater than a fourth threshold value, a further re-tensioning process is not carried out. | 07-31-2014 |
20150041257 | METHOD FOR PROVIDING THE APPLICATION FORCE GENERATED BY A PARKING BRAKE - In a method for providing the application force generated by a parking brake, which is at least partially generated by an electromechanical brake device having an electric brake motor, a retensioning process is terminated in the event that (i) the motor current exceeds a limit value or (ii) the rotational speed of the motor drops below a limit value. | 02-12-2015 |
