Patent number: 10814849Abstract: An electronically pressure-controllable vehicle braking system and a method for controlling an electronically pressure-controllable vehicle braking system are described. Such vehicle braking systems may stabilize a vehicle, assist the actuation of the vehicle braking system, and/or enable a fully automated or semi-automated driving operation. For this purpose, the vehicle braking systems include a primary actuator system which sets or regulates different braking pressures at the wheel brakes and furthermore includes an electronically controllable secondary actuator system which protects the vehicle braking system against, inter alia, failure of the primary actuator system.Type: GrantFiled: February 23, 2017Date of Patent: October 27, 2020Assignee: Robert Bosch GmbHInventors: Alfred Strehle, Marko Flinner, Matthias Schanzenbach, Thomas Schmidt

Patent number: 10604128Abstract: An electronically slip-controllable vehicle braking system for a motor vehicle, including an actuatable brake master cylinder, to which at least one wheel brake that is associated with one wheel of a front axle of the vehicle, and at least one wheel brake that is associated with one wheel of a rear axle of the motor vehicle, are detachably connected. An electronically controllable first actuator suite of the braking system establishes and regulates mutually differing brake pressures in the wheel brakes as a function of the respectively existing slip conditions. An electronically controllable second actuator suite establishes and regulates a uniform brake pressure at the wheel brakes, and a third actuator suite limits the brake pressure generated by the second actuator suite at the at least one wheel brake associated with the wheel of the rear axle. Electronic control application to the actuator suites is accomplished via an electronic control device.Type: GrantFiled: October 25, 2017Date of Patent: March 31, 2020Assignee: Robert Bosch GmbHInventors: Alfred Strehle, Marko Flinner, Matthias Schanzenbach, Thomas Schmidt

Patent number: 10286884Abstract: A vehicle brake system having electronic pressure regulation and a related method, in which the system stabilizes a vehicle, supports the actuation of the brake system, and/or enables a fully/partly automated driving operation. The system has a primary actuator system that sets/regulates different brake pressures at the wheel brakes, and an electronically controllable secondary actuator system that secures the vehicle brake system against primary actuator failure. For a primary actuator error, the secondary actuator is controlled so that the secondary system produces a brake pressure that, based on the dynamic axle load displacement, occurring during a braking process, in the direction of a front axle, is greater than the brake pressure that is convertable into a rear axle wheel brake braking power. A device reduces this brake pressure at the rear axle wheel brake to a value at which the vehicle wheel, assigned to this wheel brake, does not lock.Type: GrantFiled: May 1, 2017Date of Patent: May 14, 2019Assignee: ROBERT BOSCH GMBHInventors: Alfred Strehle, Marko Flinner, Matthias Schanzenbach, Thomas Schmidt

Patent number: 8653775Abstract: A method and a device for controlling and/or regulating an electric motor. Such electric motors are used for example in motor vehicles in the form of pump motors. In general, the electric motor is supplied with electrical energy from a battery and/or using a generator. The controlling and regulation take place using a high-frequency pulse width modulation (PWM). When the electric motor is started, the PWM is used to continuously increase the motor current required for the operation of the electric motor, e.g. beginning from 0.Type: GrantFiled: November 23, 2006Date of Patent: February 18, 2014Assignee: Robert Bosch GmbHInventors: Matthias Schanzenbach, Juergen Hachtel, Markus Baumert

Patent number: 8489301Abstract: A device for controlling the brake pressure in a hydraulic brake system with the aid of a pressure-limiting valve that limits the brake pressure to a predefined threshold value, and to that end is driven by an electronic device in accordance with a valve characteristic curve. The setting accuracy can be improved considerably if an estimating unit for estimating the brake pressure, a sensor system for measuring the brake pressure, a unit for determining a pressure difference between the measured brake pressure and the estimated brake pressure, as well as a controller unit which drives the pressure-limiting valve as a function of the pressure difference are provided.Type: GrantFiled: May 3, 2007Date of Patent: July 16, 2013Assignee: Robert Bosch GmbHInventors: Bettina Crepin, Michael Bunk, Roland Galbas, Ralf Kinder, Matthias Schanzenbach, Christoph Betz

Publication number: 20120319466Abstract: In a method for carrying out an automatic braking in a motor vehicle with the aid of a pump which delivers a brake fluid in the direction of the wheel brakes, the brake pressure prevailing in the brake circuit is limited by a valve, which is overflowed when a settable pressure threshold is reached, and thus limiting the brake pressure. The dynamics of the pressure build-up is improved if the valve opens only at higher pressures, since a greater share of the volume flow coming from the hydraulic pump is then in fact conducted to the wheel brakes and is not able to flow off prematurely via the valve.Type: ApplicationFiled: October 4, 2010Publication date: December 20, 2012Inventors: Michael Bunk, Matthias Schanzenbach, Michael Reichert, Markus Jung
