摘要： There are provided a vehicle steering control device and a vehicle steering control method, by which an ideal steering feeling can be achieved. A turning controller 19 is configured to set as a target turning angle of a turning wheel an addition value obtained by adding a steady steer control amount that is a control amount depending on a steering angle and a differential steer control amount that is a control amount depending on a steering angular velocity. In this situation, when a driver is increasingly turning a steering wheel 1, the differential steer control amount is computed to be smaller than the differential steer control amount when the driver is not increasingly turning the steering wheel 1. Accordingly, the phase of the turning angle with respect to the steering angle in the steering returning operation can be delayed as compared to the phase in the steering increasing operation.

摘要： A control computing unit (11) blends a feedforward axial force (T FF ) and a feedback axial force (T FB ) at an allocation ratio (GF 1 , GF 2 , GF 3 , and GF 4 ), based on an axial force difference, a lateral acceleration (Gy), a vehicle velocity (V), a steering angle (δ), and a steering angular velocity (dδ/dt) so as to set a final axial force. Then, the control computing unit (11) applies a steering reaction force based on the final axial force that has been set.

摘要： A control computing unit (11) allocates the current axial force and the transverse-G axial force at the predetermined allocation ratio (K 2 , K 1 ) to calculate a feedback axial force (T FB ) which is the steering-rack axial force. Then, the control computing unit (11) drives the reaction force motor (9A) on the basis of the calculated feedback axial force (T FB ). Additionally, the allocation ratio (K 1 ) of the transverse-G axial force is set to be greater than the allocation ratio (K 2 ) of the current axial force.
