Abstract
A device is provided for detecting inadequate electric braking and commutation to a safety brake is intended for a vehicle with electric traction, in particular a rail vehicle, which is provided with a traction chain, the system including a first electric, non-safety brake which is integrated in the traction chain and a second safety brake. The device includes a member for commutation from the first brake to the second brake, a device for monitoring the braking performance of the first brake using data for measurement of the intensity of a current, a decision device for commutating from the first brake to the second brake when a predetermined threshold value is exceeded and a device for transmitting a commutation command to the at least one commutation member.
