The invention relates to an autonomous retarder system for a vehicle including a retarder (10) having a central rotor (11) and two stators (12), one on each side of the rotor (11). The rotor (11) is rigidly coupled to an axle (1). A generator (20, 30, 50) is also included, coupled to the retarder (10), for supplying same with electrical energy. In addition, the generator (20, 30, 50) comprises a stator (22) and a rotor (21, 31, 51) coupled to the retarder.

Provided are a brake system, a brake device, and a method of controlling brakes for railroad cars in which control can be multiplexed with a simple configuration. In a brake system 1 for railroad cars includes brake control devices 11, 12, 13 provided in railroad cars 101, 102 103 respectively that form a unit 104. Each brake control device 10 (11, 12, 13) is capable of outputting information of the corresponding car (101, 102, 103) to the other brake control devices 10 through a transmission device 20. The brake control device 10 can calculate a total necessary braking force value BRA required for braking all of the cars 101, 102 103 using the information output from the other brake control devices 10 to the transmission device 20.
