A rail vehicle brake controller (100) receives a brake command (BC), and in response thereto, produces a master control signal (CTRL) that controls an electrically operated brake unit (140) to perform a braking operation. The brake controller (100) contain...

In a rail vehicle (100) a control unit (140) controls a set of brake/ traction units (101, 161; 102, 162; 103, 163; 104, 164) by control signals (B1, A1; B2, A2; B3, A3; B4, A4) to apply a respective brake/traction force to a respective wheel axle (131, 13...

A parking brake system for a rail vehicle (100) contains a brake actuator (120) for receiving a parking-brake command (cmdp) and producing an electric brake-force signal (BF). A brake unit (200) contains first and second pressing members (211, 212) and a r...

An electrically operated brake assembly (200) for a rail vehicle contains: a rotating member mechanically linked to a wheel axle of the rail vehicle, at least one friction member (221; 222) movable between an engaged position in which the at least one fric...

An overall weight (m) of a rail vehicle (100) is estimated by obtaining a power signal (P) indicating an amount of power produced by a set of drive units (101, 102, 103) to accelerate the rail vehicle (100) between first and second speeds (v; v). Then, the...

A rail vehicle (100) has a number of wheel axles (131, 132, 133, 134) and a set of brake units (101, 102, 103, 104) applying respective brake forces to the wheel axles. A power signal (Pm) indicates the power needed to accelerate the rail vehicle (100) bet...
