Claim:
A vehicle steering control device configured to execute automatic steering and manual steering, comprising: an automatic control amount-setting device that sets a target automatic control amount based on information about a behavior of a vehicle and about an ambient environment; a steering control amount-setting device that sets a target steering amount based on a manual steering amount input by a driver and the target automatic control amount set by the automatic steering amount-setting device; and a steering device that steers the vehicle based on the target steering amount set by the steering control amount-setting device, wherein when a contribution of the target automatic control amount is larger in setting of the target steering amount than the contribution of the manual steering amount, the steering control amount-setting device sets the target steering amount so as to raise a responsiveness in a lateral shift of the vehicle relative to the responsiveness in turning of the vehicle, in contrast with when the contribution of the target automatic control amount is equal to or smaller in setting of the target steering amount than the contribution of the manual steering amount.
