In a vehicle travel support device 10, an ECU 4 includes an air resistance distribution acquisition unit 41, a target traveling position determination unit 43, and a travel support unit 44. The air resistance distribution acquisition unit 41 acquires air resistance distribution in the left and right directions of a host vehicle. The target traveling position determination unit 43 determines a target traveling position of the host vehicle against a preceding vehicle using the air resistance distribution. The travel support unit 44 performs support to guide the host vehicle to the target traveling position. According to this vehicle travel support device 10, even if an area in which a large aerodynamic effect is obtained by a preceding vehicle deviates in the left and right directions of the host vehicle, the host vehicle can be guided to a position corresponding to the deviation. Because of this, the fuel efficiency can be effectively improved.
