Electromechanical or electromagnetic wheel brake cylinder and production method for the same, brake system for a vehicle, and method for autonomous braking of a vehicle

In a method, which can be performed by a control device for carrying out an emergency braking and/or panic braking of a vehicle, in a first phase, a setpoint vehicle deceleration requested instantaneously by a driver is ignored and a motor of an electromechanical brake booster is operated in a predefined high power mode such that a main brake cylinder pressure in the main brake cylinder is increased; in an intermediate phase, the main brake cylinder pressure is reduced to a setpoint pressure by pumping brake fluid from the main brake cylinder into the at least one wheel brake cylinder and the motor force of the motor is reduced to a setpoint force; and the brake pressure increase in the at least one wheel brake cylinder is continued during a second phase only if the driver requests instantaneously a setpoint vehicle deceleration.

In a method for controlling a hydraulic braking system, in the event of a failure of a primary brake actuator system, a secondary brake actuator system is activated.

Method for controlling a hydraulic braking system in a vehicle

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.

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. According to the invention, in the event of a fault in the primary actuator system, an activation of the secondary actuator system takes place in such a way that the secondary actuator system generates a braking pressure which, taking into account the dynamic axle load displacement in the direction of the front axle taking place during a braking operation, is greater than the braking pressure convertible into a braking power by the wheel brakes on the rear axle. A provided unit reduces this braking pressure at the at least one wheel brake of the rear axle to a value at which the wheel of the motor vehicle assigned to the at least one wheel brake of the rear axle does not lock.

Electronically pressure-controllable vehicle braking system and method for controlling an electronically pressure-controllable vehicle braking

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.

Electronically slip-controllable braking system

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.

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.

In a method for actuating a hydraulic braking system, a hydraulic fluid is temporarily stored in a storage chamber when the antilocking system is activated. An additional hydraulic buffer volume of the storage chamber increases as the vehicle speed decreases.

Method for actuating a hydraulic braking system

In a method for actuating a hydraulic braking system, a hydraulic fluid is temporarily stored in a storage chamber when the antilocking system is activated and recirculated back into the brake circuit with the aid of a recirculation pump. The target pump speed of the recirculation pump depends on the degree of filling of the storage chamber with hydraulic fluid and in addition on the control frequency of the antilocking system.

A wiper blade for wiping windows of motor vehicles has an elongated rubber-elastic wiper strip placeable on a window to be wiped and arranged substantially longitudinally axially parallel on a surface of a strip-shaped, spring-elastic support element which is connected with a wiper arm which is spring loaded toward the window and driven transversely to a longitudinal extension of the wiper blade, and a leading-edge face extending longitudinally of the wiper blade and substantially parallel to the window and facing into a wind so as to form an acute angle with the window.

Wiper blade for windows of motor vehicles

A support element for a wiper strip belonging to a wiper blade for motor vehicle windows is proposed, which assures proper contact of a wiper strip, belonging to the wiper blade, with the window to be wiped. The support element is embodied as elongated in bandlike fashion, and it comprises an elastic plastic. The rubber-elastic wiper strip, elongated in bandlike fashion, can be secured to the support element longitudinally axially parallel. An especially durably operationally reliable support element is obtained if the support element is made from a fiber-reinforced thermoplastic plastic, and the fibers are admixed with the plastic.
