Publication number: 20060232126Abstract: In a method for actuating an electrically actuatable parking brake system, the brake torque on the braked wheels is reduced in order to prevent the wheels braked by the parking brake from locking when the vehicle is traveling at a vehicle speed exceeding a predetermined minimum speed and the wheel slip exceeds a defined threshold.Type: ApplicationFiled: December 2, 2003Publication date: October 19, 2006Inventors: Bernhard Giers, Thomas Pröger, Rainer Klusemann

Patent number: 6510372Abstract: A method of electronic brake force distribution in a two-axle four-wheel vehicle 1 effects a compensation of the speed differences between left and right vehicle side during cornering. To this end, a compensation speed is calculated for the curve-inward rear wheel 6 and added to the individual wheel speed of the rear wheel 6 to be compared with a vehicle reference speed. The individual wheel reference speed of this wheel, which is this way increased in relation to the individual wheel speed of the curve-inward rear wheel 6, prevents a premature activation of electronic brake force distribution because the produced individual wheel reference speed is closer to the vehicle reference speed than the individual wheel speed. This permits better utilizing brake force during cornering.Type: GrantFiled: September 1, 1999Date of Patent: January 21, 2003Assignee: Continental Teves AG & Co., OHGInventors: Markus Zenzen, Thomas Pröger

Patent number: 6474149Abstract: The invention provides a method of detecting a defective condition on a pressure switch arrangement which at least assumes a defective condition on the said pressure switch assembly whenever a signal arrives at an input of an electronic computing unit which cannot be associated either to the opened or to the closed condition of the pressure switch. Moreover, a defective condition on the pressure switch arrangement mounted in the brake system of a vehicle is assumed, once the pressure switch signal refers to an actuated brake although the vehicle is significantly accelerated. Conversely, a defective condition is also assumed if the vehicle significantly decelerates although the pressure switch signal refers to a lack of brake pressure. Also, an appropriate pressure switch arrangement is provided which, with the pressure switch closed, generates a rectangular signal and, with the pressure switch opened, generates a high level on the input II of an electronic computing unit.Type: GrantFiled: March 1, 1999Date of Patent: November 5, 2002Assignee: Continental Teves AG & Co., OHGInventors: Norbert Ehmer, Thomas Proger, Markus Zenzen

Patent number: 6367892Abstract: The present invention discloses a brake system with electronic brake force distribution which includes additional criteria of deactivation of the electronic brake force distribution. Deactivation of the electronic brake force distribution is intended to occur, on the one hand, if a pressure increase phase lasts longer than a defined time (50). On the other hand, another criterion of deactivation (60) is deceleration-responsive, and an additional check is made whether or not braking is pedal operated (62).Type: GrantFiled: March 25, 1999Date of Patent: April 9, 2002Assignee: Continental Teves AG & Co., OHGInventors: Thomas Proger, Markus Zenzen

Patent number: 6203122Abstract: A method of electronic brake force distribution is applied to contribute to vehicle stability even in the event of failure of the system that detects failure of the front-axle brake circuit (13) in a vehicle (1). The method involves initiating a pressure maintenance or pressure reduction phase only after the standards with respect to a minimum vehicle deceleration upon brake circuit failure are met. This way, it is ensured that the standards are observed, on the one hand, and locking of the rear wheels (6,7) before the front wheels (4,5) is prevented with great likelihood, on the other hand. Thus, electronic brake force distribution (EBD) is switched over to less sensitive criteria. This makes allowance for both possibilities in the event of a failure of a pressure switch (15), i.e., that the front-axle brake circuit (13) is intact or that it is defective.Type: GrantFiled: July 9, 1999Date of Patent: March 20, 2001Assignee: Continental Teves AG & Co.

Patent number: 6119062Abstract: In a brake system with electronic brake force distribution, the electronic brake force distribution is deactivated as soon as the maximum vehicle deceleration achieved during electronic control falls below by a given factor between 0 and 1, for example, two thirds. The purpose is that an early exit from the electronic brake force distribution is effected even if the brake light switch is defective, with the result that unnecessary valve actuations and the risk of underbraking are prevented. The present invention is applicable to brake systems where the criteria for the activation of the electronic brake force distribution are independent of a brake light switch signal, and to other brake systems if there is a defect in the brake light switch. The present invention makes it possible to sense in good time that the driver has taken his/her foot off the brake pedal or no longer desires heavy deceleration.Type: GrantFiled: April 23, 1999Date of Patent: September 12, 2000Assignee: Continental Teves AG & Co.

Patent number: 6009366Abstract: A method of monitoring a brake system which is equipped with anti-lock control (ABS) and a system for electronic control of brake force distribution (EBV). The system includes two brake circuits in a black/white brake circuit split-up, the EBV function or control is principally released only when the vehicle deceleration exceeds a predetermined limit value (GWN). To identify a front-axle brake circuit failure, acceleration criteria, i.e., criteria responsive to the acceleration behavior of the vehicle wheels, are predetermined and monitored. Further, slip range monitoring in conjunction with acceleration range monitoring is performed.Type: GrantFiled: November 12, 1998Date of Patent: December 28, 1999Assignee: ITT Manufacturing Enterprises Inc.Inventors: Dieter Burkhard, Norbert Ehmer, Thomas Proger, Alexander Volz, Gerhard Kunz, Helmut Fennel

Patent number: 5795039Abstract: A circuit for a brake system with pressure fluid distribution, anti-lock control, and traction slip control. The circuit includes circuits to monitor the brake system and to change over or disconnect the control in response to defects and/or the respective control situation or driving situation. Upon failure of any one of the sensors which sense wheel rotation behavior or one sensor per axle or in the presence of an incorrect sensor signal, the vehicle reference speed is produced on basis of the intact sensors, and an electronic brake force distribution control function is still possible, however, an anti-lock control or a traction slip control is prevented. When the defective sensor is a rear-wheel sensor, both rear wheels are controlled synchronously.Type: GrantFiled: January 14, 1997Date of Patent: August 18, 1998Assignee: ITT Automotive Europe GmbHInventors: Helmut Fennel, Norbert Ehmer, Alexander Kolbe, Robert Schmidt, Thomas Proger
