Patent number: 6964455Abstract: An anti-lock brake system for a tri-axle wheeled vehicle equipped with wheel speed sensors and modulators for adjusting brake pressure. The modulators are actuated by a six-channel electronic control unit. The modulators associated with the front axle of the vehicle are individually actuated. The modulators associated with the two rear axles of the vehicle are side-by-side or axle modulators, each actuated jointly by respective end stages of the six channels. The electronic control unit detects whether the anti-lock brake system in which it is installed is a compatible anti-lock brake system. An error signal indicating improper installation is delivered.Type: GrantFiled: February 10, 2005Date of Patent: November 15, 2005Assignee: WABCO GmbH & Co. oHGInventors: Gerhard Ruhnau, Gerald Stanusch

Patent number: 6622077Abstract: An anti-lock braking system (ABS) for multi-axle vehicles equipped with multiple wheel-speed sensors and modulators for adjustment of braking pressure. The brake cylinder for each wheel may be controlled by an individual modulator, or, alternatively, a single common supply axle modulator may regulate both brake cylinders of an axle. In a preferred embodiment, the ABS is controlled by an ABS electronic control unit (ECU), which has four regulating channels with four corresponding end stages for controlling three modulators, where one of the modulators is commonly regulated by two end stages. The ECU also detects whether it is coupled to a proper ABS. The ABS electronic control unit eliminates the danger of an undetected installation of an ABS electronic control unit into an incompatible anti-lock braking system.Type: GrantFiled: June 7, 2002Date of Patent: September 16, 2003Assignee: WABCO GmbH & Co.

Patent number: 6224171Abstract: A method applicable for use in wheeled vehicles permits correction of a vehicle reference speed following a real or apparent deceleration indicated by wheel speed signals, caused for example by a fault in wheel sensing. In order to prevent a brief period of insufficient braking of the vehicle due to an erroneously high vehicle reference speed during a subsequent ABS regulation, wheel slip regulating signals are monitored. If a wheel slip regulating signal appears for a given number of wheels and lasts for a longer period than a predetermined time, an intervention in the normal regulating process is made, and the vehicle reference speed is set to the value of the wheel speed of the wheels associated with a wheel slip regulating signal.Type: GrantFiled: October 27, 1998Date of Patent: May 1, 2001Assignee: WABCO GmbHInventors: Henrich Riedemann, Gerald Stanusch, Ingo Tha, Thomas Wolf

Patent number: 6204658Abstract: An evaluation method for an output signal of a sensing device for scanning a cyclic movement, consisting of a rotatable pole wheel provided with equidistant teeth and an inductive sensor, permits recognition and display of damage to the pole wheel, in particular defective or missing teeth. Contrary to known evaluation processes, where error monitoring of the output signal is carried out for a relatively short time period comprising few signal cycles of the output signal, an observation of the output signal is effected for a sufficiently long time span in the evaluation process according to the invention, such that within the time span, at least two complete revolutions of the pole wheel are completed. To detect damage to the pole wheel, the sudden changes in the output signal occurring in the course of a complete revolution are recorded and are compared with changes recorded in previous, complete revolutions.Type: GrantFiled: November 5, 1998Date of Patent: March 20, 2001Assignee: Wabco GmbHInventors: Gerald Stanusch, Hans Holst

Patent number: 5436836Abstract: An electronic regulating system for regulating the supply of pressure medium to each brake cylinder of a vehicle having a plurality of wheels thereby preventing spinning of the wheels upon starting and locking of the wheels upon braking, comprises wheel speed sensors which detect the rotation of the wheels and which produce signals indicative of the individual rotational speeds of the wheels, and an electronic control unit which monitors the individual rotational speeds of the wheels and which controls the supply of the pressure medium to the brake cylinders based on the individual rotational speeds. The electronic control unit includes a speed signal processor which receives the signals produced by the wheel speed sensors and which determines the individual rotational speeds of the wheels and a vehicle reference speed therefrom.Type: GrantFiled: April 22, 1992Date of Patent: July 25, 1995Assignee: W A B C O Standard GmbHInventors: Hans Holtz, Helmut Pannbacker, Erwin Petersen, Gerald Stanusch

Patent number: 5265468Abstract: An error detection and display system for an apparatus having first and second operating states comprises a testing device, a display unit (e.g., a warning light), and a switch-on control unit. The testing device runs primary error test cycles for detecting errors of a first kind which occur during the first operating state of the apparatus (e.g., a vehicle at standstill), and secondary error test cycles which occur and can be detected only in the second state of the apparatus (e.g., the vehicle moving above a predetermined minimum speed). The system also includes a non-volatile memory wherein all occurrences of errors of the second kind are stored. The switch-on control unit switches on the testing device and the warning light when the vehicle is first started. If no error of the first kind is detected by the testing device and no error of the second kind is stored in the error memory, the switch-on control unit switches off the warning light while the vehicle is still at a standstill.Type: GrantFiled: February 27, 1992Date of Patent: November 30, 1993Assignee: WABCO Standard GmbHInventors: Hans Holst, Harald Kaess, Erwin Petersen, Johann Rothen, Gerhard Ruhnau, Gerald Stanusch
