Title
(EN) CLUTCH ENGAGING CONTROL METHOD AND CONTROL SYSTEM IN HYBRID POWER OUTPUT DEVICE
(FR) PROCÉDÉ ET SYSTÈME DE COMMANDE D'EMBRAYAGE DANS UN DISPOSITIF DE PRODUCTION DE PUISSANCE HYBRIDE
Abstract
(EN)
The present invention provide s a clutch engaging contro l method in a hybrid power output device, wherein the device comprises an engine, a first motor, a clutch and a second motor that are connected in sequence, a battery, and a speed reducing mechanism and a drive shaft that are connected to the output end of the second motor; the method comprises: (a) detecting the rotation speed ω2 of the second motor and setting the rotation speed ω2 as the target rotation speed ω0 of the first motor, when the vehicle is driven by the second motor and the engine is required to be started to provide assistance to the second motor; (b) starting the first motor to drive the engine, and controlling the actual rotation speed ω1 of the first motor to be close to the target rotation speed ω0; (c) switching the state of the first motor from a driving motor to a power generator when the actual rotation speed ω1 of the first motor is approximately equal to the target rotation speed ω0; and (d) engaging the clutch. The method can improve the dynamic response time of the engine and suppress impact in the clutch engaging process. The present invention furt her provides a clutch engaging control system in a hybrid power output device.

La présente invention se rapporte à un procédé de commande d'embrayage dans un dispositif de production de puissance hybride, le dispositif comprenant une machine, un premier moteur, un embrayage et un second moteur qui sont reliés de manière séquentielle, une batterie, un mécanisme réducteur de vitesse et un arbre de transmission qui sont reliés à l'extrémité de sortie du second moteur. Le procédé de l'invention consiste: (a) à détecter la vitesse de rotation (2) du second moteur et à établir la vitesse de rotation (2) comme vitesse de rotation cible (0) du premier moteur lorsque le véhicule est entraîné par le second moteur et que la machine doit démarrer afin de fournir une assistance au second moteur; (b) démarrer le premier moteur afin d'entraîner la machine, et régler la vitesse de rotation réelle (1) du premier moteur (10) de façon qu'elle se rapproche de la vitesse de rotation cible (0); (c) commuter le premier moteur de l'état de moteur d'entraînement à celui de générateur de puissance lorsque la vitesse de rotation réelle (1) du premier moteur est approximativement égale à la vitesse de rotation cible (0); et (d) enclencher l'embrayage. Le procédé de l'invention permet d'améliorer le temps de réponse dynamique et de supprimer l'impact lors du processus d'embrayage. L'invention concerne en outre un système de commande d'embrayage (15) dans un dispositif de production de puissance hybride.
