A generation control device for a hybrid vehicle in which an electrical generator is driven by an engine, and a battery is charged by operation of the electrical generator and the engine, includes: a shift position detection unit that detects a shift position; a brake detection unit that detects whether a brake is on or off; a charging start unit; an increasing/decreasing unit that conducts increasing operation or decreasing operation; and a control unit that starts to charge the battery when the shift position is a non-travel position, the brake is on, and the charging start unit is operated. The control unit that, after starting to charge the battery, increases a parameter related to the electrical generation when the increasing operation is conducted, or the decreases the parameter when the decreasing operation is conducted. The control unit controls the engine and the power generator based on the set parameter.
