  • Publication number: 20200223413
    Abstract: A method for controlling a hydraulic braking system of a vehicle. The braking system includes a controllable first braking pressure generator and a sensor for a deceleration signal of the vehicle. The method includes: impressing a pressure characteristic with the aid of the first braking pressure generator on an original setpoint braking pressure; and monitoring the deceleration signal for the presence of a deceleration characteristic corresponding to the pressure characteristic.

  • Patent number: 10604128
    Abstract: 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.

  • Patent number: 10576953
    Abstract: An electronically slip-controllable braking system including an actuatable master brake cylinder, to which at least one wheel brake, associated with a wheel of a front axle and at least one wheel brake, associated with a wheel of a rear axle of a vehicle, are connected. An electronically activatable first actuator system sets and regulates brake pressures different from one another in the wheel brakes as a function of the particular present slip conditions. An electronically activatable second actuator system effectuates the setting and regulating of a uniform brake pressure at the wheel brakes and a third actuator system limits the brake pressure generated by the second actuator system at the wheel brakes associated with the wheels of the rear axle. The third actuator system controls a second pressure medium connection between the associated wheel brake of the rear axle and a pressure medium storage container.

  • Publication number: 20190359191
    Abstract: A method for controlling an electronically slip-controllable power braking system of a motor vehicle. Power braking systems are equipped with a plunger unit, which includes a plunger piston accommodated in a plunger cylinder and delimiting a working chamber, for generating brake pressure in brake circuits. This plunger piston is actuatable by an electronically activatable drive in a pressure buildup direction or in the opposing spatial direction thereto in a pressure reducing direction. A time-limited drive of the plunger piston takes place in the pressure reducing direction as soon as an actual brake pressure generated by the plunger unit has reached a predefinable setpoint brake pressure and a decoupling of a wheel brake and the plunger unit from an associated brake circuit has taken place.

  • Publication number: 20190210575
    Abstract: A method for carrying out a driver-independent braking maneuver of a motor vehicle includes ascertaining a reference trajectory of the motor vehicle, ascertaining a lateral guidance force variable representing the lateral guidance force necessary for guidance of the motor vehicle on the reference trajectory, ascertaining, as a function of the lateral guidance force variable, a longitudinal force variable representing the maximum longitudinal force transferable in a longitudinal vehicle direction, and, based on the longitudinal force variable and driver-independently, establishing a braking force variable representing the braking force of the motor vehicle.

  • Patent number: 10286884
    Abstract: 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.

  • Publication number: 20190126899
    Abstract: 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.

  • Patent number: 9132816
    Abstract: A brake system, and a method for operating a brake system of a vehicle. To reduce a braking force, brake fluid is able to be discharged from the braking device via a cross-section adjusting member which connects a delivery device to the braking device, in a controlled and/or regulated manner, into an intermediate reservoir and is delivered to the main brake cylinder using the delivery device. The discharge of the brake fluid from the braking device of the brake system takes place, at least at times, at a discharge volume flow that is greater than the maximum delivery volume flow of the delivery device, and when a certain operating state of the braking system occurs, the discharge volume flow is reduced.
