Abstract:
A control apparatus for a hybrid vehicle comprising an engine for outputting a driving force of the vehicle, a motor for generating an auxiliary driving force for assisting the engine power in response to the driving condition of the vehicle, and a storage battery for storing a regenerative energy obtained by a regenerative operation of the motor at the time of supplying electric power to the motor or at the time of reducing speed of the vehicle; the control apparatus of the hybrid vehicle comprises:a travel start detecting device for detecting a travel start of the vehicle; a residual capacity detecting device for detecting a residual capacity of the storage battery; an initial residual capacity comparison device for comparison of the initial residual capacity with the lower limit initial residual capacity; a lower limit threshold value setting device for setting the lower limit threshold value of the discharge quantity for said initial residual capacity; a lower limit threshold value setting device for setting the lower limit threshold value of the discharge quantity for said initial residual capacity; an upper limit threshold value setting device for setting the upper limit threshold value of the discharge quantity for said initial residual capacity; a motor control changing device for changing the control of said motor when the residual capacity of the storage battery reduces to said lower limit threshold value; and a mode setting release device for releasing the setting of the motor control mode changed by said motor control changing device when the residual capacity of the storage battery reaches said upper limit threshold value; said control apparatus further comprises: an initial residual capacity setting device for setting the initial value by assigning the lower limit initial residual value to the initial residual value when it is determined by said initial residual capacity comparison device that the initial residual capacity is lower than the lower limit threshold value.
