An automatic driving system for a vehicle includes an external sensor (1) and an electronic control unit (10). The electronic control unit (10) is configured to estimate whether the vehicle peripheral information detected by the external sensor (1) allows the vehicle to keep a vehicle target speed set on the basis of a vehicle travel plan or temporarily does not allow the vehicle to keep the vehicle target speed. The electronic control unit (10) is configured to, when it is estimated that the vehicle peripheral information temporarily does not allow the vehicle to keep the vehicle target speed, generate a plurality of vehicle travel plans during a travel duration for which it is estimated that the vehicle peripheral information temporarily does not allow the vehicle to keep the vehicle target speed, and select one of the plurality of vehicle travel plans, which provides a lowest fuel consumption of an engine. |
