  • Patent number: 10040435
    Abstract: A method for braking a rail vehicle with a brake system includes providing an open-loop and/or closed-loop control device having a wheel slide protection control unit for ensuring a predefined coefficient of adhesion between the wheels of the rail vehicle and the rail, in which brake demand signals of different origin are taken into account by the open-loop and/or closed-loop control device. A slide protection function of the wheel slide protection control unit is deactivated for braking that is free of slide protection when at least two brake demand signals having different origin and having a brake demand which exceeds a specified deceleration limit, are present at the same time. A corresponding open-loop and/or closed-loop control device for a brake system and such a brake system are also provided.

  • Patent number: 9656649
    Abstract: A brake actuator for a braking system of a rail vehicle is configured to detect an anti-skid corrected braking target value from a brake control, or has an anti-skid correction device configured to correct the braking target value detected by the brake control by a reduction signal of an anti-skid control device to the anti-skid corrected braking target value. To improve the controllability of the brake actuator, an anti-skid monitoring device is provided, to which the anti-skid corrected braking target value and the brake target value are applied, and is configured to switch from a first position to a second position under at least one predefined first switching condition, and to switch from the second position back to the first position under a second switching condition. In the first position, the anti-skid corrected braking target value is provided.

  • Publication number: 20150367822
    Abstract: A brake unit for a vehicle which can be mounted on running gear of the vehicle has devices for making available a regulated braking force and a passive emergency braking force. In order to permit safe braking by the emergency braking force, even in the case of a fault during the provision of the regulated braking force, there is provision that the devices are of suitable configuration to make available the passive emergency braking force in a load-corrected fashion and include a pressure signal transmitter and a load corrector for correcting the load of the passive emergency braking force. The load corrector sets a preload pressure of the pressure signal transmitter as a function of electrical output signals of a fallback device to a load-corrected set point value.

  • Patent number: 9079591
    Abstract: An actuator for a brake system of a rail vehicle has a set-value detection unit that outputs a set value or a set value corrected by a reducing signal of an anti-skid control device for a decelerating force or a decelerating torque to a set-value control device. The latter controls the set value to a first output set value. A switch-over device connects an output of the set-value control device to a input of a set-value/force conversion device in a first switching position. In a second switching position, the set-value/force conversion device receives the signal from a fall-back unit. Braking devices convert an actual value of the force into an actual value of the decelerating force or decelerating torque. When impermissible deviations from a fast braking set value in a fast-braking operation are found, the switch-over device switches from the first to the second switching position.
