To provide an electric power unit capable of controlling a travel of an automatically steered vehicle more safely in a case of loss of electric power supply, the automatically steered vehicle comprising the electric power unit, and an electric power supply method for the automatically steered vehicle.SOLUTION: An electric power unit 20 comprises: a first electric power supply system 21 which supplies electric power to a motor 9 driving and rotating travel wheels 7; a transformer device 22 which is supplied with a part of electric power from the first power supply system 21 and transforms a voltage; a second power supply system 31 which supplies electric power of the electricity having been transformed by the transformer device 22 to a steering device 10; and a first preliminary electric power supply 35 which supplies the electric power to the transformer device 22. The first preliminary power supply 35 can supply the electric power to the transformer device 22 when the voltage of electric power detected by VD 21b of the first electric power supply system 21 drops below a predetermined value.SELECTED DRAWING: Figure 2
【課題】電源喪失時に、より安全に自動操舵車両の走行を制御することが可能な電源装置と、電源装置を備えた自動操舵車両と、自動操舵車両への電力供給方法とを提供する。【解決手段】電源装置20は、走行輪7を回転駆動するモータ9へ電力を供給する第一電源系統21と、第一電源系統21からの電力の一部が供給されて電圧を変圧する変圧装置22と、変圧装置22で変圧された電気の電力を操舵装置10に供給する第二電源系統31と、変圧装置22に電力を供給する第一予備電源35と、を備えている。第一予備電源35は、第一電源系統21のVD21bで検知される電力の電圧が所定値よりも小さくなった際に、変圧装置22に電力を供給可能である。【選択図】図2
