A control computing unit allocates the current axial force and the transverse-G axial force at the predetermined allocation ratio to calculate a feedback axial force which is the steering-rack axial force. Then, the control computing unit drives the reaction force motor on the basis of the calculated feedback axial force. Additionally, the allocation ratio of the transverse-G axial force is set to be greater than the allocation ratio of the current axial force.

Steering control apparatus and steering control method

A vehicle steering control apparatus and vehicle steering control method make it possible to suppress a steering state of a steering operation element from being different from the driver's intention, in starting the driving source. A backup clutch, which is switchable between a release state where a torque transmission path is mechanically decoupled and an engagement state where the torque transmission path is mechanically coupled, is set to the engagement state in starting the engine. When the steering torque detected after the engine starts becomes equal to or lower than a clutch release start torque, the backup clutch in the engagement state is switched to the release state.

Vehicle steering control apparatus and steering control method

A control computing unit allocates a feedback axial force and a feedforward axial force at an allocation ratio based on an axial force difference which is a difference between the feedback axial force and the feedforward axial force to set a final axial force as a steering-rack axial force. The control computing unit drives a reaction force motor on the basis of the set final axial force.
