A pneumatic brake pedal module for a brake-by-wire brake system of a vehicle is disclosed. The brake pedal module includes a pivotably mounted brake pedal and a damping unit. The damping unit is mechanically coupled to the brake pedal to generate a resistance when the brake pedal is actuated. The damping unit comprises a housing and a piston, which is mounted movably in the housing and divides an internal space of the housing into a pressure chamber and a vacuum chamber. The pressure chamber and the vacuum chamber are connected to one another in terms of flow. The piston has on its running surface an encircling annular space in which a ring seal is accommodated in an axially movable manner. The ring seal is located at least in a flow path between the pressure chamber and the vacuum chamber and forms a restrictor in the at least one flow path, which restrictor frees different flow cross sections in the at least one flow path depending on the axial direction of movement, and damps the movement of the piston with differing degrees of strength depending on a direction of movement of the piston.

A brake pedal module for a brake-by-wire brake system of a vehicle is disclosed, having a carrier component for securing the brake pedal module on the vehicle, a brake pedal pivotably mounted on the carrier component, and a damping unit for producing a resistance during actuation of the brake pedal.

A brake pedal module for a “brake-by-wire” brake system of a vehicle is disclosed. The brake pedal module has a pivotably mounted brake pedal and a damping unit. The damping unit is mechanically coupled to the brake pedal in order to generate a resistance when the brake pedal is actuated. The damping unit comprises a housing and a piston mounted in the housing in such a way that it can be moved from an initial position into an end position. In its initial position, the piston is supported on a base of the housing via at least two elastic elements arranged in series. A further elastic element is arranged parallel to the at least two elastic elements on the base of the housing. The further elastic element is not subject to any load in an initial position of the piston.

A brake pedal module for a “brake-by-wire” brake system of a vehicle is disclosed. The brake pedal module has a carrier component for securing the brake pedal module on the vehicle, a brake pedal, which is mounted pivotably on the carrier component, and a damping unit, which is mechanically coupled at one end to the brake pedal and at the other end to the carrier component in order to produce a resistance when the brake pedal is actuated. The brake pedal module is a pre-assembled structural unit which is self-contained in terms of forces.

This electric braking device is provided with: an electric motor MTR that, in accordance with an operation amount Bpa of a braking operation member BP, generates a pressing force Fba, being a force pressing a friction member MSB against a rotary member KTB that rotates integrally with a wheel WHL of the vehicle; and a circuit board KBN to which a processor MPR and a bridge circuit BRG are mounted. The device is further provided with a rotation angle sensor MKA for detecting the rotation angle Mka of the electric motor, and drives the electric motor MTR on the basis of the rotation angle Mka. An end face Mmk of the rotation angle sensor MKA is fixed so as to be in contact with the circuit board KBN. The device is further provided with a pressing force sensor FBA for detecting the pressing force Fba, and drives the electric motor MTR on the basis of the pressing force Fba. An end face Mfb of the pressing force sensor FBA is fixed so as to be in contact with the circuit board KBN.

A method for operating a brake system. A brake request signal characterizing a brake request is generated by actuating a positioner system of an actuating circuit, and a setpoint brake pressure required in an active circuit is ascertained based on the brake request signal. An actual brake pressure is set in the active circuit according to the setpoint brake pressure using a pressure generation device by moving a displacement piston using an electric motor to actuate a wheel brake coupled with the active circuit. Under the condition that the brake request signal is constant over a predefined period of time, a pressure modulation is carried out, which includes setting the actual brake pressure in the active circuit to a value that is greater than the setpoint brake pressure, and lowering the actual brake pressure by moving the displacement piston using the electric motor until the setpoint brake pressure is reached.

A foldable electronic pedal apparatus is proposed. The foldable electronic pedal apparatus has both a foldable function that can pop up and hide the pedal and an electronic pedal function, and can tune necessary pedal effort, stroke, and hysteresis that are different for every kind of vehicle by having a high-load spring module and a hysteresis lever.

A pedal sensor is provided with a carrier that can be mounted to a motor vehicle. A housing is formed at the carrier, and a pedal arm is mounted on the carrier so as to be pivotable. A mechanism to transmit movements of the pedal arm relative to the carrier is arranged in the housing, and a sensor for measuring the movements is provided. A damping element is fixed to the carrier in a groove in such a way that any contact between the pedal arm and the carrier is dampened. The damping element is securely held on the carrier. This is achieved by the damping element being secured on both sides against slipping out of the groove.

A method for installing a stroke sensor is provided such that the stroke sensor can be easily adjusted using a simple process. The method has the steps of; obtaining a relationship between the magnetic field and the indicator value while moving the magnet in the first direction relative to the magnetic field detecting element within a predetermined relative movable range, and writing the relationship in the processor; after the relationship is written in the processor, preventing the predetermined relative movable range from being shifted in the first direction by means of a jig for preventing positional shift, wherein the jig includes an element that fixes relative positions between the magnetic field detecting element and the magnet; attaching the magnet and the magnetic field detecting element, which have been prevented from being shifted, to different structures that are movable in the first direction relative to each other, and removing the jig.
