Abstract:
1. A safety braking system for a vehicle with electric traction including a traction chain, the safety braking system comprising: a first, electric, non-safety brake which is integrated in the traction chain; a second, safety, brake; at least one member for commutation from the first brake to the second brake, the at least one member including an electromechanical commutator for connecting and isolating an electromechanical machine to and from a traction inverter; a monitoring device capable of monitoring the braking performance of the first brake using data for measurement of an intensity of a current; a decision device for commutating from the first brake to the second brake when a predetermined threshold value is exceeded by the intensity measurement data; and a device for transmitting a commutation command to the at least one commutation member.
