VEHICLE STEERING CONTROL DEVICE AND VEHICLE STEERING CONTROL METHOD
First Claim
1. A vehicle steering control device capable of executing automatic steering and manual steering, comprising:
- an automatic control amount-setting device that sets a target automatic control amount based on information about behavior of a vehicle and about 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 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 better a responsiveness in a lateral shift of the vehicle relatively to the responsiveness in turning of the vehicle, in comparison 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.

Abstract
A vehicle steering control device capable of executing automatic steering and manual steering includes: an automatic control amount-setting device that sets a target automatic control amount based on information about vehicle behavior and 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 set target automatic control amount; and a steering device that steers based on the set target steering amount. When the target automatic control amount contributes more in the setting of the target steering amount than the manual steering amount does, the steering control amount-setting device sets the target steering amount so as to better the responsiveness in the lateral shift of the vehicle relatively to the responsiveness in the turning of the vehicle, in comparison with when the target automatic amount does not contribute more than the manual steering amount.
