Title (EN) STEERING SYSTEM
(FR) SYSTÈME DE DIRECTION
(JA) ステアリングシステム
Abstract:
(EN) The present invention makes it possible to correct the orientation of a vehicle steered by a steering amount command in accordance with the state of the vehicle, and maintains the travel stability of the vehicle. The present invention comprises, in addition to a first steering device (14) that steers vehicle wheels of a vehicle (101) according to a steering command outputted by a steering command device (200), a second steering device (150). The second steering device (150) comprises a mechanism unit (150a) that steers the vehicle wheels (2) via the drive of an electric motor (27) provided inside a tire housing, and a control unit (150b) that controls the electric motor (27). The control unit (150b) controls the electric motor (27) on the basis of vehicle information indicating the state of the vehicle (101) as sensed by a vehicle information detection unit (110).
(FR) La présente invention permet de corriger l'orientation d'un véhicule dirigé par une instruction de quantité de direction conformément à l'état du véhicule, et maintient la stabilité de déplacement du véhicule. La présente invention comprend, en plus d'un premier dispositif de direction (14) qui dirige des roues de véhicule d'un véhicule (101) en fonction d'une instruction de direction émise par un dispositif d'instruction de direction (200), un second dispositif de direction (150). Le second dispositif de direction (150) comprend une unité de mécanisme (150a) qui dirige les roues (2) de véhicule par le biais de l'entraînement d'un moteur électrique (27) disposé à l'intérieur d'un boîtier de pneu, et une unité de commande (150b) qui commande le moteur électrique (27). L'unité de commande (150b) commande le moteur électrique (27) sur la base d'informations de véhicule indiquant l'état du véhicule (101) tel que détecté par une unité de détection d'informations de véhicule (110).
(JA) 操舵量指令により操舵される車両の向き対して車両の状態に応じてその補正を可能とし、車両の走行安定性を維持する。操舵指令装置(200)が出力する操舵の指令に従い車両(101)の車輪を転舵させる第1のステアリング装置(140)の他に、第2のステアリング装置(150)を備える。第2のステアリング装置(150)は、タイヤハウジング内に設けられ電動モータ(27)の駆動により車輪(2)を転舵させる機構部(150a)、および前記電動モータ(27)を制御する制御部(150b)からなる。この制御部(150b)は、車両情報検出部(110)により検知される車両(101)の状態を表す車両情報に基づいて、前記電動モータ(27)を制御する。
