To provide a vehicle driving assistance device capable of selecting a travel passage with a proper vehicle behavior.SOLUTION: A vehicle driving assistance device includes a controller for selecting one passage candidate as a selected passage from a plurality of passage candidates RC (RC1 and PC2) to a target arrival location. The controller performs passage candidate calculation processing for calculating a plurality of passage candidates, passage cost calculation processing for calculating respective passage costs of the plurality of passage candidates, and passage selection processing for selecting one passage candidate as a selected passage based on the passage cost. In the passage cost calculation processing, the controller sets a potential energy distribution 50 which has a smaller energy value as a distance from the target arrival location increases with the target arrival location as a center, calculates a sum of kinetic energy and potential energy of the vehicle along each passage candidate, and calculates a cumulative value of a fluctuation component of the sum along each passage candidate as passage cost.SELECTED DRAWING: Figure 3
