Abstract

A rail vehicle combination has a first motor train unit and at least one second motor train unit, each of which has a drive mechanism and a brake mechanism. Each of the brake mechanisms of the at least two motor train units has a plurality of brake units. In order to obtain a flexible utilization of the brake mechanism capacities of the coupled motor train units, a brake effect management system is formed in the coupled state. The management system is of a higher order than the brake mechanisms and is connected thereto. The management system is configured to distribute a braking effect onto the brake units of the at least two motor train units.

wherein the distribution algorithm is configured to take a first limit of adhesion between a rail and a wheel into consideration when calculating partial braking effects to be allocated if said anti-skid devices in said motor train units are inactive and, if at least one anti-skid device is active, taking a second limit of adhesion between the rail and the wheel into consideration when calculating the partial braking effects to be allocated, wherein the second limit of adhesion is less than the first limit of adhesion.

2. The rail vehicle unit according to claim 1 , wherein each said motor train unit is formed as a combination of vehicle units and wherein at least one different brake unit of a particular brake mechanism is allocated to each of the vehicle units.

3. The rail vehicle unit according to claim 1 , wherein said braking effect management system is configured for implementing a braking effect distribution for said brake mechanism of said at least one second motor train unit depending on at least one braking parameter of said brake mechanism of said first motor train unit.

4. The rail vehicle unit according to claim 3 , wherein said braking effect management system is configured, in an event of a faulty operation of said brake mechanism of said first motor train unit, to allocate at least a portion of a braking effect to be compensated to at least one brake unit of said second motor train unit.

5. The rail vehicle unit according to claim 4 , wherein said braking effect management system is configured, in an event of a complete failure of a brake unit of said brake mechanism of said first motor train unit, to uniformly distribute the braking effect to be compensated to the remaining brake units of said motor train units.
