A hybrid vehicle comprises a power generation first motor generator (1) driven by an internal combustion engine (2), and a travel second motor generator (4) driven by a battery (5). An S mode, an ECO mode and a NORMAL mode, which are basic travel modes, are switched between using a mode change switch (16). In the S mode and the ECO mode, a deceleration rate of regenerative braking on downhill roads is large, and an amount of regeneration is large. When a downhill road on a travel route has been predicted, in the S mode and the ECO mode, a controller (6) executes an SOC reduction control in which an SOC is reduced in advance before a downhill road starts, and in the NORMAL mode, the controller (6) does not execute the SOC reduction control.
