Improved lever with manual activation of traction/brake control for driving a rail vehicle

摘要

The lever (10) has an encoder (22) adapted to emit a detection signal (SD1) corresponding to instantaneous angular positions of a handle (14) around a pivot axis (A) relative to a reference direction (D). A feedback chain (60) includes a microprocessor (62) adapted to carry out instructions of a feedback algorithm (64) to generate a feedback signal (SR) from the detection signal emitted at an exit of the encoder. A servo-motor unit (66) is coupled with the handle, and generates torque on the handle according to the feedback signal received from the microprocessor.
