The intended brake cylinder pressure is preferably determined to be 2.5 times of the difference between the brake pipe pressure and the emergency reservoir pressure. In the event of brake cylinder over-pressurization or under-pressurization, an indicator is flagged, thus identifying the presence of a problem with the braking system.
100 Actuator for a brake system of a rail vehicle US14006753 2012-03-21 US09079591B2 2015-07-14 Steffen Jennek; Toni Schiffers; Manfred Wiesand
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.
