PURPOSE: To downsize an engine and improve fuel consumption by raising the revolution of the engine a little, when the residual power capacity of a power source is low, in a hybrid vehicle thereby increasing the generated power, and performing the effective supplementation for the engine by the motor at the time of high load. CONSTITUTION: The chart No.1 of (a), the chart No.2 of (b), and the chart No.3 of (c) are selected, respectively, corresponding to SOC>50%, 30%<SOC<50%, and SOC<30% of the residual power capacity SOC of the power source of a motor. As regards the speed change points (1→2, 2→3, 3→2, 2→1) of an automatic transmission of three stages for forward, for No.2, the speed change point shifts to the side of high speed more that of No.1, and for No.3, the speed change point shifts to the side of high speed more than that of No.2. In short, the revolution of the engine is raised higher by shifting the speed change point to high speed side within the block the lower SOC is. Hereby, the generated power by the motor can be increased. |
