(54) | Control system for hybrid vehicle |
(57) A control system for a hybrid vehicle has a consumed electric power calculator (20),
which calculates electric power consumption, and a battery state calculator (21),
which calculates battery state SOC of a battery (5). Based on this battery state,
a physical quantity per effective electric power calculator (25) calculates a physical
quantity per effective power when electric power equal to or greater than consumed
electric power is generated for various electric power consumption and electric power
generation, and a threshold value calculator (22) obtains a threshold value having
the same unit as that of the physical quantity per effective power using predetermined
calculation for selecting operating modes of a generator and the battery. An operating
mode selector (23) selects operating modes for an engine (1) and the battery (5) based
on comparison between the above threshold value and the physical quantity per effective
power corresponding to the consumed electric power, and a target generated electric
power calculator (24) calculates target electric power generation. An electric power
distribution controller (6) controls the engine (1) and the motor (3). |
