  • Patent number: 11912138
    Abstract: A method for braking a train set having guiding and guided locomotives interconnected by a time multiplex train bus, includes detecting actual operating current of the guided locomotive, detecting actual operating current of the guiding locomotive, detecting maximum return current, detecting pneumatic braking request of compressed air brake line, determining maximum return current and target braking of the guided locomotive from actual operating current of the guided locomotive, actual operating current of the guiding locomotive, maximum operating current and pneumatic braking request of the brake line, and electrically braking the train set using electrical target braking, while not exceeding maximum return current of the guided locomotive. The maximum current fed back by the guided locomotive is known, and the guided locomotive controlled through the main air line is braked while not exceeding the maximum return current. The braking force is divided by blending among E and pneumatic brakes.

  • Publication number: 20210171068
    Abstract: A rail vehicle, such as a power car or a locomotive, has a drive and brakes, and a drive controller for controlling the drive and the brakes of the rail vehicle. An operating device for the drive controller has a device for modifying the operating mode of the rail vehicle. The operating device has an operating lever, which can be operated by an operator of the rail vehicle, for operating the drive controller. In order to simplify the operation of the rail vehicle, the function of the operating lever is dependent on the operating mode of the rail vehicle.
