A pedal value generator 14 for a motor vehicle 30, a pedal value generator arrangement 10 and a method for controlling a motor vehicle 30 are described. A first pedal actuating surface 16 and, at a distance thereto, a second pedal actuating surface 18 are arranged on a cross member 20. A sensor arrangement 24 detects a torque M of the cross member 20 with respect to a torque axis X arranged between the first and second pedal actuating surfaces 16, 18 and for supplying an electrical actuation signal B1, B2 as a function of torque M. When an actuating force acts upon first pedal actuating surface 16 motor vehicle 30 can be accelerated and when an actuating force acts upon second pedal actuating surface 18 it can be decelerated.

A Hydraulic braking system is for braking a vehicle wheel according to a braking pressure control that includes a hydraulic pump driven by an electric motor for hydraulic pressure generation, an electronic control unit for the determination of at least one control error, based on a measured actual braking pressure compared with a pressure demand setpoint, which controls at least one actuator for a pressure increase and/or a pressure reduction of the actual braking pressure to adjust to the pressure demand setpoint. Furthermore, a method is provided for braking a vehicle wheel according to this braking pressure control and a related computer program product.

An electropneumatic parking brake control device controls a parking brake including at least one spring brake actuator. The control device includes a relay valve with a control chamber and a vent. The control chamber can be connected to the vent via at least one second throttle element and/or at least one third throttle element depending on the position of the relay piston.

A brake system for motor vehicles may include an actuation device (e.g., brake pedal), a first piston-cylinder unit having at least one piston that separates two working chambers, a control device and a pressure supply unit driven by an electric motor and having a double-stroke piston delimiting working chambers. At least one brake circuit may have associated therewith at least one wheel brake, and each wheel brake may be connected to an associated hydraulic connecting line via a controllable switching valve. An outlet valve may be assigned to a single wheel brake or to a single wheel brake of each brake circuit in a hydraulic connection between the wheel brake and a pressure medium storage container.

A pneumatic brake booster having a booster housing. The booster housing has at least two thin-walled shell elements and an elastomer sealing element. The sealing element has a sealing bead, which is of encircling form radially at the outside, and at least one rolling diaphragm portion which adjoins the sealing bead. The sealing bead is sealingly clamped in a clamping space between the shell elements. The clamping space is formed by walls which are generated in the shell elements by deformation, its radial inner wall formed by a tubular, axially forwardly extending projection, which is folded at its front edge, of the second shell element. It is proposed that a bead-side rear wall of the clamping space is formed by an encircling, radially outwardly projecting collar which is formed on the second shell element.

A method for determining a start time for a recharging procedure for a plunger device of an electronically slip-controllable power brake system, and an electronically slip-controllable power brake system having a plunger device. Plunger devices have a plunger cylinder, a plunger piston, and a plunger working space and are operable by a drive motor. A recharging procedure of the plunger device is required from time to time. The start time for a recharging procedure of the plunger device is ascertained as a function of characteristic values that describe the driving state of a vehicle equipped with the power brake system, and/or the operating state of the plunger device when an actual position of the plunger piston lies within a specifiable working range of the plunger device.

An antilock brake system is disclosed comprising a first wheel and second wheel disposed on opposite sides of a vehicle. A first electric motor providing torque to the first wheel and a second electric motor providing torque to the second wheel. A sensor monitoring each wheel and a brake on each wheel. A system is described wherein a processor monitors signals from the sensors and increases torque to either wheel when it detects that the wheel is not rotating when another wheel is rotating. Also disclosed is an antilock brake system as above with a third wheel disposed on the rear of the vehicle also comprising a sensor and brake on the third wheel and wherein the processor monitors signals from the sensors to increase torque to either front wheels when it detects that the wheel is not rotating when another wheel is rotating.

A cuboidal hydraulic block of a hydraulic power unit of a hydraulic power vehicle braking system for use in a left-hand drive vehicle or a right-hand drive vehicle to be attachable, rotatably by 180° about a horizontal axis, at a splashboard of a motor vehicle. An electric motor of a power brake pressure generator is thus selectively situated on a right or a left side of the hydraulic block.

A brake control device (10) for delivering air under controlled pressure to a pneumatic brake actuator (BA), comprising an inlet port (51) coupled to a compressed air supply circuit, a working port (54) coupled to a service brake chamber (C2) of the brake actuator (BA), a venting port (56), first and second inlet solenoid valves (31,32) for selectively connecting inlet port(s) to the working port, first and second outlet solenoid valves (41,42) for selectively connecting the working port to venting port(s), a biased check valve (12), for coupling the working port to venting port(s), the brake control unit device further comprising first and second local electronic control units (21,22) for controlling independently first and second inlet solenoid valves and first and second outlet solenoid valves.

An electromechanical brake booster for a braking system of a vehicle. The brake booster includes a spindle nut that is movable into rotation using an electric motor that is intrinsic or external to the brake booster, a spindle situated at the spindle nut and rotatably fixedly held using a support plate in such a way that the spindle and the support plate are movable into pure translatory motion using the spindle nut that is moved into rotation, and a reaction disk receiving element that is also movable using the support plate that is moved into pure translatory motion. The reaction disk receiving element includes a receiving opening in which a reaction disk is situated. The support plate and the reaction disk receiving element are designed as a one-piece component. A method for manufacturing an electromechanical brake booster for a braking system of a vehicle, is also described.
