Title:
ROAD SURFACE IMPACT STIMULATION DEVICE OF STEER-BY-WIRE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/251213
Kind Code:
A1
Abstract:
The present invention provides a road surface impact stimulation device of a steer-by-wire system, the road surface impact stimulation device comprising: a signal processing unit for calculating a difference value in wheel speed between wheels and calculating a difference value in lateral acceleration between estimated lateral acceleration and sensed lateral acceleration of a vehicle; an impact determination unit for determining whether a road surface impact has occurred on the basis of the difference value in wheel speed; and a torque calculation unit for, when it is determined that the road surface impact has occurred, calculating reaction torque according to the road surface impact on the basis of the difference value in lateral acceleration.
