Steering angle main control module changes the steering gear ratio based on the drive mode select signal from chassis control module.
Quickly switches the control after a malfunction occurs according to synchronous control using FlexRay communication.
When transferring to EPS mode, this calculates the optimum control variable for steering angle sub motor from input values of steering torque sensor to control steering angle sub motor (Torque assist control).
