A control apparatus for a hybrid vehicle determines a scheduled travel route from a current location of the hybrid vehicle to a destination on the basis of the map information. The control apparatus further determines a downhill section included in the scheduled travel route by using gradient information acquired for a road section at a time when the vehicle has traveled on the road section and using gradient information stored in a navigation database (86) for a road section on which the vehicle travels for a first time. The control apparatus determines a section from a downhill control start point to an end point of the target downhill section as a downhill control section. The downhill control start point is a point located a predetermined first distance closer to the vehicle (10) from a start point of the target downhill section. When the vehicle (10) travels on the downhill control section, the control apparatus executes downhill control to reduce the target residual capacity of an accumulator (64).
