(DE) VORRICHTUNG ZUR STEUERUNG EINER GASPEDALREAKTIONSKRAFT
(EN) ACCELERATOR REACTION FORCE CONTROL APPARATUS
(FR) APPAREIL DE COMMANDE DE LA FORCE DE RÉACTION D'UN ACCÉLÉRATEUR
Abstract
(EN) An accelerator reaction force control apparatus is provided with an accelerator position detecting device (6), a reaction force varying device (101) and a threshold value setting device (10). The reaction force varying device (101) varies a reaction force of the accelerator so as to increase a reaction force of the accelerator (2) by a prescribed increase amount with respect to a base reaction force when the accelerator position is equal to or larger than an accelerator position threshold value. The reaction force varying device (101) also varies a reaction force increase rate at a first increase rate during a first reaction force increase period of the increase of the reaction force, and at a second increase rate during a second reaction force increase period of the increase of the reaction force. The second increase rate is larger during the second reaction force increase period than during the first reaction force increase period.
(FR) L'invention porte sur un appareil de commande de la force de réaction d'un accélérateur qui comprend un dispositif (6) de détection de la position de l'accélérateur, un dispositif (101) de modification de la force de réaction et un dispositif (10) de réglage d'une valeur de seuil. Le dispositif (101) de modification de la force de réaction modifie une force de réaction de l'accélérateur de manière à augmenter une force de réaction de l'accélérateur (2) d'une quantité d'accroissement prescrite par rapport à une force de réaction de base lorsque la position de l'accélérateur est égale ou supérieure à une valeur de seuil de position de l'accélérateur. Le dispositif (101) de modification de la force de réaction modifie aussi le taux d'accroissement de la force de réaction avec un premier taux d'accroissement pendant une première période d'accroissement de l'accroissement de la force de réaction et avec un second taux d'accroissement pendant une seconde période d'accroissement de la force de réaction de l'accroissement de la force de réaction. Le second taux d'accroissement est plus grand pendant la seconde période d'accroissement de la force de réaction que pendant la première période d'accroissement de la force de réaction.
