Abstract: Disclosed is an electronic brake system. The electronic brake system according to the present embodiment comprises: a first block in which a mechanical part that is mechanically operated and linked with a brake pedal is disposed; a second block in which an electronic part electronically operated and controlled by an electronic control unit is disposed; and a connection line which hydraulically connects the first block and the second block. The first block and the second block can be installed at positions spaced apart from each other in a vehicle, and thus the mountability of the brake system and the degree of freedom in designing the vehicle can be improved.

Abstract: Provided is a brake control device which reliably generates wheel cylinder fluid pressure in all the wheels FR to RR even at the time of failure of the brake control device, can reliably decelerate or stop a vehicle, has a simplified system configuration, and has high reliability for automatic driving. A brake device 101 of the present invention includes a first fluid pressure unit 102p which supplies brake fluid to first wheel cylinders 118a and 118d, a second fluid pressure unit 102s which supplies brake fluid to second wheel cylinders 118b and 118c, and a connection pipe 119 which connects the first fluid pressure unit and the second fluid pressure unit to allow the brake fluid to flow. The first fluid pressure unit and the second fluid pressure unit open a first shut-off valve 104p and a second shut-off valve 104s, respectively, in a case where a failure is detected in at least one of the first fluid pressure unit and the second fluid pressure unit.

Abstract: A brake system comprises a reservoir; a brake pedal; a master cylinder including a first master chamber, a second master chamber, a first master piston, and a second master piston; a first hydraulic circuit including at least one first hydraulic wheel brake; a second hydraulic circuit including at least one second hydraulic wheel brake; and a hydraulic pressure supplier including an actuator for pressurizing the first hydraulic circuit and the second hydraulic circuit depending on an operation of the brake pedal in a normal operating mode. The master cylinder further comprises a locking chamber and an elastic pedal feel element arranged in the first master chamber to be in contact with the first master piston and the second master piston for generating a pedal force when the brake pedal is operated while the second master piston is locked in the normal operating mode.

Abstract: The present invention relates to an electronic parking brake device for a vehicle, in particular a utility vehicle. As a function of at least one operating state of a towing vehicle parking brake supply line and/or a trailer parking brake supply line, a towing vehicle parking brake control valve is activatable by a control unit in such a way that a towing vehicle parking brake supply line can be deaerated or aerated by the towing vehicle parking brake control valve. By manually actuating a trailer parking brake control element, a trailer parking brake control valve is activatable by the control unit in such a way that a trailer parking brake supply line can be deaerated or aerated by the trailer parking brake control valve. The present invention also relates to a method for operating the above electronic parking brake device for a vehicle.

Abstract: A brake system for a motor vehicle comprises a normally closed circuit separation valve such that the system is configured to operate in 1) in a by-wire mode when the circuit separation valve is open, such that pressure only from a pressure chamber of a linear actuator is delivered to both first and second pairs of wheel brakes, and 2) in a circuit separation mode with the circuit separation valve in the normally closed position, such that pressure from a tandem master cylinder is delivered only to the first pair of wheel brakes, and such that pressure from the pressure chamber of the linear actuator is concurrently delivered only to the second pair of wheel brakes. The system can provide braking pressure even in the event of a by-wire braking module leak that causes inoperability of an ECU.

Abstract: Method and apparatus for activation of an emergency brake function (8; 8null) within a vehicle (1) in dependence of whether a regular brake function. The method and apparatus include a first brake circuit and a second brake circuit that are out of order. A first sensor (20; 20null) is included for detecting whether the pressure (p1) in the first brake circuit falls below a first limit value (p1G). A second sensor is included (21; 21null) for detecting whether the pressure (p2) in the second brake circuit falls below a second limit value (p2G). A means is also provided (16; 24, 25, 26) for activation of said emergency brake function if the pressure (p1) in the first brake circuit falls below the first limit value (p1G) at the same time as the pressure (p2) in the second brake circuit falls below the second limit value (p2G). An activation process for an emergency brake function is provided regarding the method. A secure activation of an emergency brake function is permitted, and a reduced risk of this emergency brake function being activated unnecessarily is also provided.
