Title:
STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/039183
Kind Code:
A1
Abstract:
According to the present invention, a first electric steering mechanism (16L) is provided with a first motor actuator (20L), a second electric steering mechanism (16R) is provided with a second motor actuator (20R), and these mechanisms are individually controlled by control devices (22L), (22R). Thus, the first electric steering mechanism (16L) and the second electric steering mechanism (16R) can be controlled differently, and thereby arbitrarily defined steering controllability can be provided thereto and steering performance thereof can be improved. In addition, since steering assistance force is applied by the motor actuators (20L), (20R), a quick responsiveness is achieved, and the steering controllability can be further improved.
