Control system for hybrid vehicle

Abstract

A control apparatus of a hybrid vehicle is provided, capable of charging the storage battery, when the residual capacity of the storage battery is decreasing and when a predetermined amount of the initial residual capacity is decreased. The control apparatus of the present invention comprises a initial residual capacity comparison means S for comparing the initial capacity of the storage battery with the discharge depth limiting initial lower limit; a lower limit threshold value setting means S and an upper limit setting means S for setting the lower limit threshold value and the upper limit threshold value for the discharge amount from the initial residual capacity; a motor control changing means S for changing the control mode of the motor when the residual capacity of the storage battery reaches the upper limit threshold value; and a mode setting release means S for releasing the setting of the motor control mode set by the motor control changing means when the residual capacity of the storage battery reaches the lower limit threshold value; wherein the control apparatus further comprises a initial residual capacity setting means S for assigning the lower limit initial residual capacity to the initial residual capacity when it is determined by the initial residual capacity comparison means that the initial residual capacity of the storage battery is lower than the lower limit initial residual capacity.
