Abstract
(EN)
A joystick is the most convenient and intuitive device for driving a wheelchair. However, sometimes, a joystick operation for which a user did not intend occurs, and there are cases for which the joystick is operated without consideration for the driving state of the wheelchair. Also, the wheelchair is sometimes not driveable according to operation of the joystick even though the joystick operation, for which the user intends, is performed. The present invention does not use the joystick directly as a driving device for driving the wheelchair and changes the concept of a joystick into that of a device for freely expressing user intent for driving the wheelchair, so as to filter out unintended joystick operation of the user, the joystick operation with no consideration of the driving state of the wheelchair, or the like, and enable the wheelchair to be driven exactly according to user intent in consideration of the current operating state of the wheelchair. The joystick of the present invention can not only be used as a traveling operation device of the wheelchair, but can be used as an operation device of various attached devices such as a seating assistance device and a wheelchair seat height adjustment device.

Un levier de commande qui est un dispositif des plus pratiques et intuitifs pour conduire un fauteuil roulant. Cependant, parfois, se produit une action du levier qu'un utilisateur n'a pas souhaitée, et il existe des cas dans lesquels le levier de commande est actionné sans tenir compte de l'état de conduite du fauteuil roulant. De plus, le fauteuil roulant peut parfois ne pas pouvoir être conduit conformément à l'actionnent du levier de commande même si l'actionnement du levier, voulu par l'utilisateur, est effectué. La présente invention n'utilise pas le levier de commande directement en tant que dispositif de conduite pour conduire le fauteuil roulant et transforme le concept d'un levier en celui d'un dispositif permettant d'exprimer librement l'intention de l'utilisateur de conduire le fauteuil roulant, de façon éliminer un actionnement de levier accidentel par l'utilisateur, l'actionnement du levier sans tenir compte de l'état de conduite du fauteuil roulant, ou une action similaire, et permettre au fauteuil roulant d'être conduit exactement selon l'intention de l'utilisateur en tenant compte de l'état de fonctionnement actuel du fauteuil roulant. Le levier de commande de la présente invention peut non seulement être utilisé en tant que dispositif d'actionnement de déplacement du fauteuil roulant, mais peut être utilisé en tant que dispositif d'actionnement de divers dispositifs annexes tels qu'un dispositif d'assistance à l'assise et un dispositif de réglage de hauteur de siège de fauteuil roulant.

조이스틱은 휠체어를 운전하기 위한 가장 편하고 직관적인 장치이다. 그러나 때로는 사용자가 의도하지 않는 조이스틱 조작이 주어지고, 휠체어 운전 상태를 고려하지 않고 조이스틱을 조작하는 경우도 있다. 또 조이스틱 조작이 사용자의 의도된 표현이라 하더라도 조이스틱의 조작대로 휠체어가 운전되지 않은 경우가 있다. 본 발명에서는 조이스틱을 휠체어를 운전하기 위한 직접적인 운전 장치로 활용하지 않고, 조이스틱을 휠체어 운전을 위해 사용자의 의사를 자유롭게 표현하는 장치로 개념을 바꾸어, 의도하지 않은 사용자의 조이스틱 조작이나 휠체어 운전 상태를 고려하지 않은 조이스틱 조작 등을 걸러내고, 휠체어의 현재 작동 상태를 고려하여 사용자의 의도대로 휠체어가 정확하게 운전될 수 있게 된다. 본 발명의 조이스틱은 휠체어의 주행 운전 장치로뿐만 아니라, 승하차 지원장치, 휠체어 좌석 높낮이 조절장치 등의 다양한 부속장치의 운전 장치로도 활용될 수 있다.
