Beschreibung
Zusammenfassung:	A mechanical braking system is provided for a vehicle having an electric propulsion system which is utilized for retard speed regulation. While the retard speed regulation is normally performed via electric braking, in some conditions the electric braking is not able to maintain a desired speed for the vehicle. In this condition, upon receipt of a signal from the electric propulsion system, the mechanical braking system is automatically activated so as to maintain the vehicle at the desired speed. La présente invention concerne un système de frein mécanique de véhicule ; il comporte un système de propulsion électrique utilisé pour retarder la régulation de vitesse. Tandis que la régulation de vitesse de retard est normalement effectuée par frein électrique, dans certaines conditions, ce frein ne peut pas maintenir une vitesse souhaitée pour le véhicule. Dans cette condition, à réception d'un signal du système de propulsion électrique, le système de frein mécanique est automatiquement activé afin de maintenir le véhicule à la vitesse souhaitée.
