Title:
STEERING SYSTEM FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/185398
Kind Code:
A1
Abstract:
Provided is a steer-by-wire steering system for a vehicle that can reduce or eliminate the impact noise generated by the rack at the rack end. A control unit of the steering system is configured to determine a target steered angle (αt) according to the steering angle and drive the steering actuator so as to cause the steered angle to coincide with the target steered angle, and to determine a target reaction force (Tt) according to a steered state of the wheels and drive the reaction force actuator so as to cause the reaction force to coincide with the target reaction force. The control unit is further configured to set a maximum limit (αmC) on the target steered angle, the maximum limit being a value smaller than a physical maximum steered angle (αmP) of the wheels imposed by the steering mechanism.
