  • CPU 31 determines whether the count value (elapsed time) of timer 31a has reached a predetermined value. (Step S4). When the measured value has not reached the predetermined value (NO in step S4), the CPU 31 continues counting of the timer 3 la (step S5).
  • An example of the predetermined value of the elapsed time is that the side door 2 is closed. This is the time required for the motor 51 to open and close without stopping even from the position B to the fully open position C.
  • CPU 31 determines that side door 2 is stopped at the open position (YES in step S4).
  • the CPU 31 supplies an operation stop signal to the clutch operation circuit 33 to set the clutch unit 52b to the engagement mode (step S6).
  • step S7 the CPU 31 determines whether or not the handle switch 36 is turned on.
  • the CPU 31 supplies an operation signal to the clutch operation circuit 33 to set the clutch unit 52b to the non-coupling mode (step S8), and the timer 31a The count value is reset (step S9).
  • the embodiment may be modified as follows!
  • the clutch unit 52b enters the non-joining mode when the friction between the brake disc 89 and the back surface 87a of the side plate 87 is released.
  • the friction between the brake disc 84c and the front surface 83a of the rotor 83 or the brake disc 89 and the back surface 87a of the side plate 87 causes the friction force to be smaller than the binding force in the joining mode.
  • a state in which a small binding force is generated may be used.
  • the power supplied to the clutch unit 52b in the non-joining mode is adjusted by the pulse width modulation circuit 37. From these facts, the non-joining mode in the present invention includes not only a state where no binding force is generated but also a state where a binding force is generated, though slightly.
  • the activation switch 35 is provided on the wireless key of the vehicle.
  • the present invention is not limited to this, and the activation switch 35 may be provided on the door outside handle, the door inside handle, or the instrument panel of the vehicle. good.
  • the handle switch 36 may be a capacitive touch sensor provided on the door outside handle or the door inside handle. The swing of the side door may be detected based on the detection signal of the position sensor 92, and the side door 2 may be manually opened and closed to detect the intention of the occupant.

Abstract

Un appareil d’entraînement de porte, qui consomme moins d’énergie électrique, comprend un moteur (51) disposé à l’intérieur d’une porte latérale (2) ; et un mécanisme transmettant de la puissance mécanique (52) disposé à l’intérieur de la porte latérale (2) pour transmettre la puissance d’entraînement d’un moteur (51) à un tirant (54). Le mécanisme transmettant de la puissance mécanique (52) possède un mode connexion dans lequel il transmet la puissance d’entraînement du moteur au tirant et un mode déconnexion dans lequel il interrompt la transmission de la puissance d’entraînement du moteur au tirant. Le mécanisme transmettant de la puissance mécanique, lorsqu’il est placé en mode connexion, génère une puissance qui empêche la porte latérale (2) de devenir instable par rapport à un corps latéral (1) du véhicule. En mode déconnexion, un circuit de commande d’embrayage (33) fournit une puissance électrique au mécanisme transmettant de la puissance mécanique. En mode connexion, le circuit de commande coupe l’alimentation en énergie électrique du mécanisme transmettant de la puissance mécanique.
