To provide a steer-by-wire vehicle which is fault-tolerant while inhibiting an increase in the number of parts and a vehicle mass.SOLUTION: A steer-by-wire vehicle includes a steer-by-wire steering system that performs steering according to a manipulation performed on a steering wheel, and a transmission system. The transmission system supports as speed change modes an automatic mode and a manual mode based on manual handling of gear shifting means. If a manipulation quantity of the steering wheel becomes undetectable, the transmission system is set to the automatic mode, and the steering system performs steering according to the handling performed by the gear shifting means in place of the manipulation performed on the steering wheel.SELECTED DRAWING: Figure 1
【課題】部品点数や車両質量の増大を抑制しながら、フォールトトレラントなステアバイワイヤ車両を実現する。【解決手段】ステアバイワイヤ車両は、ステアリングホイールの操作に応じて操舵を行うステアバイワイヤ方式のステアリング装置と、トランスミッション装置とを備える。トランスミッション装置は、変速モードとして、自動モードと、シフト操作手段の手動操作に基づくマニュアルモードとを有する。ステアリングホイールの操作量が検知不能となった場合、トランスミッション装置は自動モードに設定され、ステアリング装置は、ステアリングホイールの操作の代わりにシフト操作手段の操作に応じて操舵を行う。【選択図】図1
