Realized is a vehicle control device capable of performing automatic driving control that does not reduce turning accuracy of a host vehicle even when an object in a blind spot is different from an assumption and a vehicle speed decreases due to a rapid deceleration. A vehicle control device 10 includes a blind spot object estimation unit 24 that detects a blind spot region 320 of an external-field recognition sensor 12 that recognizes an external field and estimates a blind spot object 310 potential in the blind spot region 320, and a future trajectory generation unit 26 that generates a future trajectory of a host vehicle in consideration of a potential risk from the blind spot object 310 estimated by the blind spot object estimation unit 24 and surrounding information of a vehicle 1 that is the host vehicle. Furthermore, the vehicle control device 10 includes a target steering angle calculation unit 40 that calculates a curvature radius at which the vehicle 1 travels from the future trajectory generated by the future trajectory generation unit 26 and a past trajectory of the vehicle 1, and calculates a target steering angle of the vehicle 1 from the calculated curvature radius and an acceleration/deceleration of the vehicle 1.
