Abstract
A control system for a hybrid vehicle with an engine for producing a driving force for the vehicle, a motor for producing an assist driving force to assist the output from the engine, and a power storage unit for supplying electric energy to the motor and storing regenerated energy produced by regeneration of the motor when the vehicle decelerates. The control system includes a charge zone determining device for determining whether a state of charge (SOC) is within the normal use range, temporary use range, over-discharge range, or over-charge range; a generation mode selector for selecting one of a normal generation mode corresponding to normal use zone, a low generation mode corresponding to temporary use zone, a high generation mode corresponding to over-discharge zone, and a generation stop mode corresponding to over-charge zone, based on the determination by the charge zone determining device; and a generation amount setter for setting the amount of electric power generation corresponding to each mode.
