1. An apparatus for performing at least one of measuring and regulating a braking force produced by at least one of at least two brake units, which braking force of each of said at least two brake units is transmitted to a brakable element for decelerating such brakable element, said apparatus comprising:

  • (a) a deceleration sensor mounted on said brakable element to provide an output signal value that is representative of a measured deceleration value of said brakable element;

    (b) at least one mass sensor mounted on said brakable element to provide an output signal value that is representative of a measured mass value of said brakable element;

    (c) at least one temperature-dependent measuring element mounted on each brake unit to provide an output signal value that is representative of a measured temperature value of a brake unit on which said at least one temperature-dependent measuring element is mounted;

    (d) an evaluation means connected to receive said output signal values of said deceleration sensor and said at least one mass sensor and said at least one temperature-dependent element;

    (e) said evaluation means having parameters stored therein of each brake unit for determining a temperature-development of each brake unit during activation of each such brake unit;

    (f) said evaluation means having a capability of determining changes of temperature signal values of said brake units having occurred in a time interval at least during an activation of said brake units;

    (g) said evaluation means being capable of determining a medium deceleration value in said time interval; and

    (h) said evaluation means from said changes of said temperature signal values of said brake units and from said output signal value of said mass sensor and from said medium deceleration value generates and transmits an output signal value representative of a medium braking force produced by said at least one brake unit during said time interval.
