  • the steering wheel By obtaining the torque of the driving structure, it can be determined whether the steering wheel is holding a foreign object at this time. For example, when the actual torque of the driving structure is greater than the preset value, it can be judged that the driving structure requires greater torque to stow the steering wheel, which means that there are foreign objects in the moving direction of the first handle and the second handle.

  • step 310 the drive structure is rotated forward.
  • step 311 the first handle and the second handle move relative to each other in a direction away from each other.
  • the driver can be helped to remove foreign objects held by the steering wheel by immediately stopping the stowage of the steering wheel and switching the steering wheel to an open state.
  • step 312 the position of the first handle and/or the second handle is locked.
  • the steering wheel By locking the positions of the first handle and the second handle, the steering wheel can be kept open. driving The steering wheel will not be switched to the stowed state until the driver or passenger removes foreign objects that hinder the stowage of the steering wheel, thereby avoiding further damage to the steering wheel by foreign objects and human injuries to the driver and passengers caused by the steering wheel during the inspection process.
  • step 309 if the actual torque of the driving structure obtained is less than or equal to the preset value, there is no need to perform steps 310, 311 and 312, and the first handle and the second handle continue to generate force in the direction toward each other. Move relatively until the steering wheel switches to the stowed state. If the actual torque is less than or equal to the preset value, it can be determined that there are no foreign objects or obstacles preventing the steering wheel from switching to the stowed state during the operation of the driving structure. Therefore, the first handle and the second handle of the steering wheel can keep moving until they are fully Switch to storage state.

Abstract

Un volant (100) comprend un guidon (1), une structure télescopique (2) et une structure d'entraînement (3). Le guidon (1) comprend une première poignée (11) et une seconde poignée (12) qui sont agencées à l'opposé. La structure télescopique (2) comprend un premier élément de liaison (21) relié à la première poignée (11) et un second élément de liaison (22) relié à la seconde poignée (12). La structure d'entraînement (3) comprend un dispositif d'entraînement relié à la structure télescopique (2). Le dispositif d'entraînement est utilisé pour entraîner, au moyen d'une transmission par engrenage, le déplacement du premier élément de liaison (21) et/ou du second élément de liaison (22), ce qui permet de commander la première poignée (11) et la seconde poignée (12) pour qu'elles se déplacent l'une par rapport à l'autre dans un sens en direction de l'une et de l'autre, ou à l'opposé l'une de l'autre. Un plan de mouvement de la structure télescopique (2) coïncide avec un plan de mouvement du guidon (1). La présente invention concerne en outre un véhicule comprenant le volant et un procédé de commande pour le volant.
