Abstract
To provide a vehicle steering control device capable of alleviating discomfort caused by mismatch between a steering angle of a steering wheel and a steered angle of a drive wheel generated by automatic steering using an EPS device. The vehicle steering control device has a first steering assist mode of assisting driver's steering and a second steering assist mode of performing steering independently from the driver's steering. A second controller, performs phase shift suppression control to suppress a relative shift of a phase of a differential mechanism on a steering wheel side with respect to a reference phase on the steering wheel side of the differential mechanism corresponding to a phase on a rack-and-pinion side of the differential mechanism in the first steering assist mode.
