Control apparatus of hybrid vehicle

A control apparatus of a hybrid vehicle, comprising:

• an automatic transmission including an input shaft driven to be rotated by an engine torque of an engine mounted on a hybrid vehicle, an output shaft rotatably connected to driving wheels, and a plurality of gear sets configured to connect the input shaft and the output shaft to be rotatable at different gear ratios, the automatic transmission including a changing device that selects one of the plurality of gear sets to cause the selected one of the plurality of gear sets to be rotatably connected to the input shaft and the output shaft;
• a gear shift operation control device controlling a gear shift operation of the automatic transmission;
• a clutch being switchable by a clutch driving device between an engagement state where an output shaft of the engine and the input shaft of the automatic transmission are rotatably connected to each other and a disengagement state where the connection between the output shaft of the engine and the input shaft of the automatic transmission is released;
• a motor rotatably connected to the driving wheels;
• a battery connected to the motor;
• a driving assist control device performing a driving assist control by driving the motor as necessary in a driving state of the hybrid vehicle to generate an assist torque;
• a gear shift assist control device performing a gear shift assist control by driving the motor to generate the assist torque in response to a decrease of the engine torque transmitted to the driving wheels caused by the disengagement state of the clutch in a state where a gear shift condition is satisfied;
• an SOC value detection device detecting an SOC value of the battery;
• a battery temperature detection device detecting a temperature of the battery;
• a gear shift feeling deterioration inhibition device performing gear shift feeling deterioration inhibition for easing a torque fluctuation that occurs in association with a torque drop during the gear shift operation in a case where the gear shift assist control is prohibited;
• and
• a control unit that allows or prohibits each of the driving assist control, the gear shift assist control, and the gear shift feeling deterioration inhibition, based on the SOC value and the temperature of the battery.
