ABSTRACT A drive-assisted vehicle control device includes a controller that controls travel of a host vehicle. During travel on a curved route, the controller establishes a threshold value established as a boundary value for suppressing acceleration of the host vehicle. The threshold value is lower when another vehicle is present on an outside- peripheral-side curved route adjacent to a host-vehicle travel lane than when another vehicle is not present on the outside-peripheral-side curved route. The controller determines whether a lateral acceleration is greater than the threshold value during travel on a curved route. The controller permits accelerating travel on the curved route upon determining that the lateral acceleration is less than or equal to the threshold value, but suppresses accelerating travel on the curved route when upon determining that the lateral acceleration is greater than the threshold value.
