PROBLEM TO BE SOLVED: To prevent a motor assistance from being disabled which is resulting from a lack of residual capacity of a battery.SOLUTION: A control device (10) of a hybrid vehicle (1) comprises: a power generation mode control part (101) which selects, as a power generation mode of a motor (3) at vehicle deceleration, either of a first power generation mode for releasing a clutch (C1) between an engine (2) and the motor, and generating power, and a second power generation mode for applying a load on the engine by fastening the clutch, and generating power; a traveling route zone specifying part (102) which specifies a deceleration traveling route zone in a traveling route on and after a current position, and a non-deceleration traveling route zone succeeding to the deceleration traveling route zone; and a residual capacity estimation part (103) which estimates the residual capacity of a battery (31) at a finish time point of the non-deceleration traveling route zone on the assumption that the first power generation mode is selected in the deceleration traveling route zone. When the estimated residual capacity is not larger than a prescribed capacity, the power generation control part selects the second power generation mode in the deceleration traveling route zone, and in the other case, selects the first power generation mode in the deceleration traveling route zone.SELECTED DRAWING: Figure 1 |
