The present invention provides a braking system (11) for braking a train. The system comprises an electronically controlled pneumatic brake network (ECP) and a brake activation unit (14). The brake activation unit provides status reports regarding the condition of the ECP and comprises at least one sensor for monitoring one or more properties of the ECP, and at least one venting means adapted to vent the pressure from a brake pipe (21). The system also comprises a telecommunication network (15, 17, 19) adapted to communicate with the brake activation unit. The brake activation unit can be activated using the telecommunication network to vent the pressure from the brake pipe, causing the train to brake.

A braking system for a vehicle includes a first axle attached to a chassis and rotatably supporting two front wheels, with a first brake including a first electronic brake controller for controlling application of braking to the front wheels. A second axle rotatably supports two rear wheels and is detachably connected to the chassis and has a second electronic brake controller and a second brake attached thereto for braking the rear wheels. Each of the electronic brake controllers has an independent power source. The system also includes an electronic park brake controller and parking brake. A vehicle control unit is in communication with each of the electronic brake controllers for coordinating control of the braking system. One or more communications network cables, which may be wired or wireless, connect the electronic brake controllers. An electrical connector allows for swapping the second axle, which requires no fluidic connections.

A braking system for a heavy duty vehicle includes a first brake controller arranged to control braking on a front axle left wheel, and a second brake controller arranged to control braking on a front axle right wheel. The first and second brake controllers are connected by a back-up connection arranged to allow one of the first and the second brake controller to assume braking control of the wheel of the other of the first and the second brake controller. The first and second brake controllers are arranged as fail-operational brake controllers. A third brake controller is arranged to control braking on a first rear axle left wheel, and a fourth brake controller is arranged to control braking on a first rear axle right wheel. The third and the fourth brake controllers are arranged to place respective rear axle left and right wheels in an unbraked state in response to failure. The third and fourth brake controllers are arranged as fail-silent brake controllers.

A brake control device as an example of the present disclosure includes: an acquisition unit configured to acquire an output of a sensor that detects information indicating a ground contact state of a drive wheel of a vehicle; and a control unit configured to, when an acceleration operation for causing the vehicle to accelerate is performed on the vehicle stopped due to a parking brake force generated by an electric parking brake, identify the ground contact state of the drive wheel based on the output of the sensor acquired by the acquisition unit, and control the electric parking brake to release the parking brake force by a control method that differs depending on the identified ground contact state.

A method is for controlling an ABS brake system. A trailer control pressure is transmittable via a trailer control valve to a trailer to trigger trailer wheel brakes as a function of the trailer control pressure. The trailer control pressure for implementing an emergency brake function or an auxiliary brake function is delivered as a function of a position of an operating element. The method includes: determining a position of the operating element; determining a trailer target pressure as a function of the position; generating and delivering a trailer control pressure corresponding to the trailer target pressure to the control valve; determining an actual towing vehicle deceleration; reading a minimum deceleration associated with the determined position; and triggering brakes of the towing vehicle when the actual deceleration falls below the minimum deceleration read, such that the trailer control pressure does not change and the actual towing vehicle deceleration increases.

A device designed for controlling and regulating an electro-pneumatic parking brake circuit includes a manual controller configured to actuate a parking brake via the electro-pneumatic parking brake circuit, the manual controller having a first circuit arrangement and a second circuit arrangement, the first circuit arrangement being a digital, bidirectional circuit arrangement and the second circuit arrangement being an analog circuit arrangement. The device further includes control electronics electrically connected to the manual controller. The first circuit arrangement is connected to the control electronics via a first connection cable and the second circuit arrangement is connected to the control electronics via a second connection cable. The first connection cable is a digital data transmission channel configured to enable a digital data transmission between the digital circuit arrangement and the control electronics. The second connection cable is an analog data transmission channel configured to enable an analog data transmission.

The present disclosure provides an electronic hydraulic brake system that can appropriately provide redundancy braking force, that is, an electronic hydraulic brake system that provides a so-called redundancy function, in the situation in which a driver does not drive or gives less attention to driving such as autonomous driving or smart cruise control and a main braking device malfunctions.
