Title:
POWER STEERING DEVICE AND DEVICE FOR CONTROLLING POWER STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/006623
Kind Code:
A1
Abstract:
A device for controlling a power steering device having: a steering mechanism 1 for transmitting the rotation of a steering wheel to steered wheels; an electric motor 26 for imparting steering force to the steering mechanism; a transmission mechanism 25 for transmitting the rotational force of the motor to the steering mechanism; a housing 3 for accommodating at least part of the steering mechanism, the transmission mechanism, and the motor; a water detection sensor 37 for detecting moisture in the housing; and a torque sensor 10 for detecting steering torque; wherein the control device is provided with a first fault assessment unit 71 for assessing faults in the power steering device on the basis of a steering torque signal Tr, etc., and a second fault assessment unit 72 for assessing faults in the power steering device when the water detection sensor has sensed moisture. It is thereby possible to assess faults in the power steering device from a multifaceted perspective.
