In a driving assistance control apparatus for a vehicle, an acquirer acquires a detected traveling state of the vehicle and a detected traveling state of another vehicle. A controller determines whether to perform braking assistance using a deterministic indicator for collision including at least one of a time, a distance, and a required deceleration to collision with the other vehicle and a deterministic indicator for crossing including at least one of a time, a distance, and a required deceleration to reaching a path of travel of the other vehicle. The deterministic indicator for collision and the deterministic indicator for crossing are acquired using the acquired traveling state of the vehicle and the acquired traveling state of the other vehicle. Further, in response to determining to perform the braking assistance, the controller causes a driving assistance unit to perform the braking assistance.
