PROBLEM TO BE SOLVED: To provide an automatic steering system which jointly uses a drive device together with an electric power steering device, and prevents any emergency avoiding operation of a driver. SOLUTION: This vehicle steering control device comprises an image sensor 10 for detecting the positional relationship between the vehicle and a lane, a target steering quantity computing unit 41 for obtaining the target steering quantity A necessary for the traveling along the lane based on the positional relationship, a torque sensor 30 for detecting the manual steering force of operating a steering wheel by the driver, a target steering quantity computing unit 42 for outputting the target steering quantity B by changing the target steering quantity A according to the detected manual steering force, a steering angle sensor 20 for detecting the actual steering quantity, and an automatic steering force computing unit 43 for obtaining the automatic steering force necessary for agreeing the target steering quantity B with the actual steering quantity. Steering can be implemented based on the will of the driver even in the automatic steering mode. |
