Vehicle steering technology, which is currently being mass produced, uses a steering column to steer the wheels with the linear motion of the OBJ connected to the carrier using a motor-driven actuator connected to the steering column or rack gearbox. In this method, the driver"s manual torque is directly connected to the vehicle"s wheel based on the reliability of the structural connection of the mechanical device. However, in order to implement the active steering technology in the future, SBW is necessary. With the development of various sensors, the new steering technology of the vehicle has developed into the active steering technology of the vehicle by using the sensor for processing software of the recognition information, and the decision subject of the steering has been moved from the person to the ECU. Therefore, Unnecessary time of driver"s operating has increased and the steering column will be a device that measures the steering angle and provides a reaction to the driver in some situations where driver intervention is required. In the present situation that the driver has to intervene in a certain level of steering prior to the fully autonomous driving, in order to make the driver feel the current level of steering feeling for the products driven by the communication using the wire, not only securing the performance of the actuator, A reaction force column device capable of generating a steering feel of the steering wheel by the driving condition is required. In the case of the reaction force device, the motor torque is varied for each vehicle speed only for the purpose of assisting the driver. At this time, the column torque (Nm) sensed by the driver is measured, and this torque will be the reaction force in SBW. The reaction torque of SBW can be variously designed according to the type of reducer and conditions of use. As a result of the measurement, the system output is generally required to be 5Nm for a simple steering condition and 20Nm or more for a complete non-steerable condition.Therefore, the development direction of the reaction force system that can configure the SBW system and the review contents of the actual design for each new part are described.
