Abstract

Lorsqu'une valeur d'un capteur d'inclinaison (20) est inférieure à -5°, une unité de détermination d'angle cible (211) règle un angle auquel une unité de corps principal (10) s'incline vers l'avant (par exemple, θ1=2°). Lorsque la valeur du capteur d'inclinaison (20) est inférieure à -5°, une unité d'estimation d'inclinaison (214) règle une nouvelle zone morte de ±5°, avec la valeur de -5° du capteur d'inclinaison (20) comme référence au moment où la zone morte est dépassée. Dans le présent exemple, un réglage d'une force d'assistance n'est pas réalisé lorsque la valeur du capteur d'inclinaison (20) diminue encore plus et, par conséquent, la zone morte est réglée de -∞ à 0°. Ainsi, l'angle d'inclinaison cible θ1 est fixé à un second angle (θ1=2°) tandis que la valeur du capteur d'inclinaison (20) est de (0)° ou moins.
