A brake pedal assembly of a brake-by-wire system of a vehicle includes a support structure, a brake pedal pivotally engaged to the support structure at a first pivot axis, and a brake pedal emulator assembly. The brake pedal emulator assembly extends between and is pivotally engaged to the brake pedal and the support structure at respective second and third pivot axis. The brake pedal emulator assembly includes a brake pedal emulator and an adjustment mechanism aligned along a centerline intersecting the second and third pivot axis. The brake pedal emulator is constructed and arranged to displace axially when the brake pedal is actuated, and the adjustment mechanism is constructed and arranged to adjust axial displacement.

Embodiments herein are directed to an emulator assembly. The assembly includes a housing with a cavity, a pedal arm, an elongated member, a carrier, an end plate and a compressible member. The pedal arm is at least partially received in the cavity and has a pedal pad on one end. The elongated member extends and couples to the pedal arm on one end and couples to a carrier on an opposite other end. The end plate is spaced apart from the carrier. The compressible member is positioned in the space between the carrier and the end plate. When the pedal pad is depressed, the elongated member moves the carrier in a direction towards the end plate which drives the carrier into the compressible member such that the compressible material compresses to generate a force feedback onto a foot positioned on the pedal pad.

An electric booster for a vehicle including: a disc holder accommodating a reaction disc, a screw nut rotated in conjunction with an operation of a motor, a screw bolt linearly moved in conjunction with a rotation of the screw nut, a boosting block disposed between the reaction disc and the screw bolt, and contacting a radially outer portion of the reaction disc when the screw bolt moves, a pedal rod contacting a radially central portion of the reaction disc through the screw bolt and the boosting block, a disc holder pressing hole connected to the screw bolt, and disposed to face the disc holder, and a first breakage prevention gap part formed between the disc holder and the disc holder pressing hole.

Disclosed are a brake pedal assembly, a braking apparatus, and a control method, where the brake pedal assembly includes a pedal, a stroke sensor configured to detect a depression stroke of the pedal, Hall sensors spaced apart from each other in a direction parallel to an operation direction of the pedal, and a controller configured to determine the depression stroke of the pedal using any one or any combination of the stroke sensor and the Hall sensors and to determine a required braking force of a vehicle, in response to the depression stroke of the pedal.

A detection method for an electromechanical brake booster. The method includes: ascertaining, while both a driver braking force is transferred to an input element and a motor force is transferred to a support element so that a coupling element of the electromechanical brake booster which is provided downstream from the input element and the support element is also displaced at least using the motor force, whether an open intermediate gap, when the input element is present in its starting position, is closed when the coupling element is present in its starting position, and establishing an actual variable with respect to a coupling element path of the coupling element out of its coupling element starting position and/or a coupling element velocity of the coupling element in the case of an open intermediate gap using a first formula, and in the case of a closed intermediate gap using a second formula.

A hydraulic adjustment unit of a brake system in a vehicle includes a first fluid reservoir (29), a second fluid reservoir (2), a first oil return pipe (110), and a second oil return pipe (120). The first oil return pipe (110) is connected to wheel cylinders (151, 152) of a vehicle, so that brake fluid in the wheel cylinders (151, 152) of the vehicle is delivered to the first fluid reservoir (29), to depressurize wheels of the vehicle. The second oil return pipe (120) is configured to connect to the wheel cylinders (151, 152) of the vehicle through oil inlet pipes (130, 140) of a brake system, so that the brake fluid in the wheel cylinders (151, 152) of the vehicle is delivered to the second fluid reservoir (2) through the oil inlet pipes (130, 140) of the brake system, to depressurize the wheels of the vehicle.

Disclosed is a device for moving a brake pedal. The device for moving a brake pedal according to the present embodiment comprises: a lead screw fixed to an input rod of the brake pedal and having a first screw thread formed on the outer circumferential surface thereof; a first anti-rotation unit that prevents rotation of the lead screw; an actuator that provides power; a rotator rotated by the actuator; and a nut that rotates together with the rotator and is provided to be slidably movable with respect to the rotator, and that has a second screw thread formed on the inner circumferential surface thereof for meshing with the first screw thread.

A brake device for a vehicle includes: a brake pedal having a pedal portion and a lever portion that rotates about a rotation axis when the pedal portion is operated; a housing that rotatably supports the lever portion; and a plate member configured to generate a reaction force with respect to the lever portion in response to a stroke amount of the brake pedal. The plate member has a longitudinal surface defined by a side extending in a longitudinal direction of the plate member and a side extending in a width direction of the plate member. The longitudinal surface is arranged so as to face the lever portion. When the pedal portion is operated, the plate member is bent to generate the reaction force.

An electronic mechanical brake system and a vehicle. The electronic mechanical brake system includes a brake pedal, an electronic brake mechanism, a mechanical brake mechanism, a brake, and a switch mechanism with a first state and a second state. The electronic brake mechanism includes a controller and an electronic signal sensor. The controller, the electronic signal sensor, and the brake are electrically connected. When the switch mechanism is in the first state, the electronic signal sensor is configured to receive a braking signal of the brake pedal and transmit the braking signal to the controller. The controller controls the brake to brake based on the braking signal. The electronic mechanical brake system can improve driving safety. In addition, reliability of the mechanical brake system is high, and costs are low.
