Document Type and Number:
WIPO Patent Application WO/2019/224873
Kind Code:
A1
Abstract:
A steering device having a plurality of electric motors 10 which drive the wheels of a vehicle to roll, and three or more drive systems 20 which output driving forces to the electric motors 10 in order to drive the electric motors 10. A total of maximum driving forces which are the maximum values of the driving forces of the drive systems 20 provided in the steering device is set to be greater than a required driving force required to roll the wheels from a stationary position. Even in the event that one of the three or more drive systems 20 fails, the total of the maximum driving forces of the normally functioning drive systems 20 among the three or more drive systems 20 will supply the required driving force.
