POWER STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/111757
Kind Code:
A1
Abstract:
A power steering device (1) is provided with a steering shaft (3), input shaft drive sections (30, 40), an ECU (50), a camera (51), and an oil temperature sensor (56). The steering shaft (3) is connected to the steering wheel (SW). The input shaft drive sections (30, 40) apply torque in the left rotation direction and the right rotation direction to the steering shaft (3) in such a manner that the magnitude of the torque corresponds to the pressure of supplied hydraulic oil. The oil temperature sensor (56) detects the temperature of the hydraulic oil. The ECU (50) controls the pressure of the hydraulic oil, which is supplied to the input shaft drive sections (30, 40), on the basis of image information from the camera (51) and of the temperature of the hydraulic oil detected by the oil temperature sensor (56).
