Patent number: 6802401Abstract: The present invention relates to a device and a method for controlling an electrically actuated parking brake. Especially, a tip switch is provided which is movable to adopt a tensioning position, a release position, and a neutral position. For example, when the tip switch is moved by the driver to adopt the tensioning position, the control unit increases a nominal value of the actuating force of the parking brake. By actuating the tip switch, the driver is thus able to determine which actuating force is used to actuate the parking brake.Type: GrantFiled: November 30, 2001Date of Patent: October 12, 2004Assignee: Continental Teves AG & Co., oHGInventors: Jürgen Böhm, Joachim Nell

Patent number: 6662906Abstract: With electromechanically or electromotively operated brakes, adjusting a clearance presents a problem because with this type of brakes self-actuating reset means of the type provided for hydraulic brakes cannot be used. For adjustment, a neutral position of the actuator must first be determined in which at least one of the friction linings is in close proximity. To this end, the present invention provides for the change in the actuator current (IAkt) and the change in the actuator position (&phgr;Akt) to be evaluated so as to determine the contact.Type: GrantFiled: October 24, 2002Date of Patent: December 16, 2003Assignee: Continental Teves AG & Co. oHGInventors: Jürgen Böhm, Ralf Schwarz

Patent number: 6626271Abstract: The present invention relates to an electrically operable brake system and a method for its actuation. The brake system and the method are characterized in that the service brake system can be activated by two brake operating devices which are operable by the driver independently of each other. The main advantage which results is that upon failure of a brake operating device which is e.g. configured as a brake pedal module, braking of the vehicle can be achieved by means of the service brake system by way of the second brake operating device. The additional functions intended for the service brake system, such as ABS, TCS, driving dynamics control, brake assist system, etc., may then be implemented, if so desired. The redundant design of the actuation for the service brake permits achieving a high degree of operational safety because full braking functions can be maintained even in case of emergency braking.Type: GrantFiled: April 12, 2001Date of Patent: September 30, 2003Assignee: Continental Teves AG & Co., oHGInventors: Jürgen Böhm, Stefan Stölzl, Joachim Nell, Tomasz Augustyniak, Rainer Oehler

Patent number: 6550871Abstract: A method and system for controlling a brake for motor vehicles. The present invention relates to a method as well as a system for controlling a brake for motor vehicles, which can be electromechanically actuated by means of an actuator, consisting of an electric motor as well as a drive mechanism positioned downstream of the electric motor. In order to be able to increase motor speed under certain operating conditions, i.e. according to demand, without reducing the available torque, the invention provides for the slope of the speed-torque characteristic curve of the electric motor (4) to be modified by weakening components of the electromagnetic field of said electric motor (4), which affect the dynamics of same, in such a way that a higher speed (&ohgr;′1) is obtained at the same torque (M1).Type: GrantFiled: March 4, 2002Date of Patent: April 22, 2003Assignee: Continental Teves, Inc.Inventors: Jürgen Böhm, Oliver Hoffmann, Rainer Oehler, Jochen Leidech, Joachim Nell, Peter Willimowski

Patent number: 6366038Abstract: Electrical direct current actuators, which have a distinct low-pass behavior with respect to the actuating signal, are frequently used in electronic control and regulation devices. Typical examples of such actuators are d.c. motors or electromagnets. In order to minimize the power losses when controlling such electric d.c. actuators, the associated power amplifiers usually are controlled by a pulse-width modulated actuating signal in the kHz frequency. In order to ensure that the actuator also is activated with the predefined actuating signal when there are variations in the supply direct voltage, the calculated actuating signal is multiplied by a scaling factor in a first functional module, with this scaling factor being obtained in another functional module on the basis of the relationship between the actual supply voltage and the nominal supply voltage.Type: GrantFiled: July 19, 2000Date of Patent: April 2, 2002Assignee: Continental Teves AG & Co., OHGInventor: Jürgen Böhm

Patent number: 6345225Abstract: This invention relates to an electromechanical brake system, in particular for automotive vehicles, which includes a pedal module and at least two brake modules. Further, a central module may be provided. Connection between the aforementioned modules can be made by a data bus. The data bus is provided redundantly. In one embodiment, the central module can evaluate signals of a sensor system and examine them for their errors. Further, the central module can emit a corresponding nominal braking value which then is emitted to the brake modules. Thereupon, the brake modules determine appropriate actuating signals for the actuators which interact with the wheels in order to realize the driver's braking intention.Type: GrantFiled: August 11, 2000Date of Patent: February 5, 2002Assignee: Continental Teves AG & Co., OHGInventors: Jürgen Böhm, Stefan Stölzl, Peter Willimowski, Joachim Nell, Rainer Oehler
