A brake system includes an electromechanical brake having a friction surface, a lining support, an electric motor for moving the lining support, a spring acting on the lining support, and a control and monitoring unit. A control and monitoring unit ascertains from at least one first value ascertained during a first movement of the lining support by the electric motor, an operating behavior value for a real operating behavior of an operating parameter of the relevant brake, and ascertains, by a comparison of the at least one real operating behavior value to at least one stored operating behavior expectation, a correction factor. The brake control system corrects by the one correction factor and activates a regulator of the electric motor using the corrected brake control signal. The control and monitoring unit is performs a calibration by a spring force of the at least one spring during the first movement.

A braking system for a motor vehicle has a plurality of hydraulic brake units for braking each braking one wheel of the motor vehicle and a first electric parking brake actuator for braking a first wheel and a second electric parking brake actuator for braking a second wheel. A first control device comprises a first hydraulic controller which is designed and set up to drive the plurality of hydraulic brake units. In order to ensure parking brake redundancy, the first control device has a driver for driving the first parking brake actuator. A second control device is also provided, which comprises a driver for driving the first parking brake actuator and a driver for driving the second parking brake actuator.

An EPB (Electronic Parking Brake) apparatus may include: a housing unit; a motor unit mounted in the housing unit; a worm wheel gear unit engaged and rotated with the motor unit; a piston unit connected with a brake shoe; and a nut unit mounted on the worm wheel gear unit, coupled to the piston unit, and moved by the rotation of the worm wheel gear unit so as to pressurize the piston unit. The housing unit is deformed by the movement of the piston unit and restricts the operation of the motor unit.

A hydraulic braking system for a vehicle has two sub-braking systems hydraulically separated from one another. A first sub-braking system of a first axle has a first circuit, a main system with a first power supply and a first ECU, and a secondary system with a second power supply and a second ECU. The first circuit includes first and second pressure generators assigned, respectively, to the main system and the secondary system, in parallel between a fluid container and wheel brakes. A modulation unit connects the pressure generators to the wheel brakes. A second sub-braking system of a second axle includes a second circuit and an auxiliary system with a third power supply and a third ECU. The second circuit includes a pressure generator assigned to the auxiliary system arranged between a fluid container and wheel brakes, and a modulation unit connecting the pressure generators to the wheel brakes.

An anomaly detection system is on an in-vehicle network including: a first network connected to first devices that communicate using a first protocol; and a second network connected to second devices that includes a driving assistance controller communicates using a second protocol. The system includes: a communicator receiving, through the first network, first unit data including (i) source information indicating a source first device and (ii) second unit data including a data identifier; a database storing rule; and an anomaly determiner that determines whether the first unit data has anomaly by comparing the source information and the data identifier with the rule. Based on the rule, the first unit data is determined to have anomaly when the source first device is a sensing device and, according to the identifier, the second unit data is to be received by the controller.

A rail train brake control system, comprising: a single vehicle brake control unit, a train brake control unit, a traction control unit and a communication control unit; the single vehicle brake control unit is provided in each vehicle of the rail train, the train brake control unit and the communication control unit are provided in the vehicles at both ends of the rail train, and the traction control unit is disposed in motor vehicles of a plurality of vehicles; and the single vehicle brake control unit, the train brake control unit, the traction control unit and the communication control unit implement communication by means of the gateway. The system can realize flexible marshalling of a train. Further disclosed is a train comprising the train brake control system.

A parking brake device with at least one first connector line to a compressed air source and with at least one second connector line to a compressed air source, includes at least one electronically actuable bistable valve arrangement for the actuation of a spring brake cylinder and at least one further electronically actuable redundancy control valve arrangement for the actuation of a redundant brake system. At least one first control electronics module and at least one second control electronics module are provided which can be operated independently of one another. The bistable valve arrangement can be actuated via the first control electronics module, and, independently thereof, the redundancy control valve arrangement can be actuated via the second control electronics module.

An electrically controllable pneumatic brake system has a front and a rear axle brake circuit, and a manually actuable brake signal transmitter which, upon actuation, outputs a first front brake control pressure and a first rear brake control pressure. A front axle brake pressure is produced based on a front axle braking demand pressure and a rear axle brake pressure is produced based on a rear braking demand pressure. A two-channel pressure modulator system is configured to receive a braking demand signal from an autonomous driving unit and, in response thereto, output the front and rear braking demand pressure, and is further configured to receive the first front and rear brake control pressure and, at least in an error situation, to output the front braking demand pressure depending on the first front brake control pressure and/or the rear braking demand pressure depending on the first rear brake control pressure.
