Abstract
(EN)
This present disclosure provides a controlling method for an actuator, an actuator, and an electromechanical brake system of brake technology. The controlling method comprises: receiving brake demand; controlling the electric motor based on the brake demand; if the brake demand satisfies a preset stationary condition within a preset period, controlling the brake force holding device to lock the shaft. In this way, frequent variations of the brake demand caused by interference from ambient disturbance or the driver's unsteady brake instructions may be prevented so that the actuator can be locked timely, thereby maintaining a continuous brake torque output with low power consumption or zero power consumption to provide a continuous brake force to the vehicle.

L'invention concerne un procédé de commande pour un actionneur, un actionneur et un système de frein électromécanique de technologie de frein. Le procédé de commande consiste à : recevoir une demande de frein; commander le moteur électrique sur la base de la demande de frein; si la demande de frein satisfait une condition stationnaire prédéfinie dans une période prédéfinie, commander le dispositif de maintien de force de frein pour verrouiller l'arbre. De cette manière, des variations fréquentes de la demande de frein provoquées par des interférences provenant d'une perturbation ambiante ou d'instructions de frein non stationnaires du conducteur peuvent être empêchées de sorte que l'actionneur puisse être verrouillé rapidement, ce qui permet de maintenir une sortie continue de couple de frein avec une faible consommation d'énergie ou une consommation d'énergie nulle pour fournir une force de frein continue au véhicule.
