摘要： By calculating energy used by friction brake equipment, the amount of friction brake shoe/pad wear is monitored. As amount of energy supplied reaches a percentage of the friction brake shoe/pad energy design limit, and indication for inspection is provided. If the supplied friction energy continues to increase the brake material must be replaced. The software logic limits are tunable for custom configuration by maintainace personnel. This invention measures amount of friction effort supplied with respect to time and distance in a software controller brake system and allows the software to determine when the friction brake material must be replaced on actual data and avoids costly damage from braking with worn out shoes/pads. This invention annunciates through the software when the friction material requires inspection and replacement and provides software logic to indicate remaining material thickness.

摘要： A method in part enables a wheel slip control system that controls slip on a per axle basis to control slip on a per truck basis. The wheel slip control system issues on a per axle basis an axle reduction signal indicative of a percentage by which to reduce the braking force that would normally be applied to one wheel/axle combination on a truck of a rail vehicle. The method includes the step of converting the axle reduction signals issued on a per axle basis to a truck reduction priority signal indicative of a percentage by which to reduce the braking force on a per truck basis. For rail vehicles featuring dynamic braking equipment another step involves commanding the dynamic braking equipment to reduce the dynamic braking force being applied to the wheel/axle combinations of the truck in response to the percentage carried by the truck reduction priority signal. Still another step involves commanding the friction braking equipment to apply an appropriate amount of friction braking force to the wheel/axle combinations of the truck so as to resolve the slip experienced thereby. The appropriate amount of friction braking force represents the sum of the total braking force sought to be applied to the wheel/axle combinations of the truck less first a product of the total braking force and the percentage carried by the truck reduction priority signal and less second the dynamic braking force being applied to the wheel/axle combinations of the truck.
