Abstract:
A control apparatus for a hybrid vehicle with an engine and a motor as the drive sources of the vehicle, and a power storage unit for storing electrical energy from the output of the engine or a part of the kinetic energy of the vehicle which has been converted by the motor, and an automatic transmission, comprising:a charge condition detection section which detects the charge amount of the power storage unit and determines a mode including at least a charge and discharge permit mode which permits charge and discharge of the power storage unit, and a discharge suppression mode which permits charge and suppresses discharge of the power storage unit; and an assistance determination section which determines whether or not to perform driving force assistance for the engine by the motor, wherein the assistance determination section has at least a departure assistance determination section which determines departure assistance that performs driving force assistance by the motor at the time of departure of the vehicle, and an acceleration assistance determination section which determines acceleration assistance that performs driving force assistance by the motor at the time of acceleration of the vehicle, and the departure assistance determination section determines to not permit assistance in the case where the charge condition detection section determines the discharge suppression mode and determines discharge suppression time permit determination which permits assistance in the discharge suppression mode, and in the case where driving force assistance by the motor is permitted by the discharge suppression time permit determination, the departure assistance is performed by the motor even in the discharge suppression mode.
