Abstract:
1. A control apparatus of a hybrid vehicle, comprising: an automatic transmission including an input shaft driven to rotate by an engine torque of an engine mounted at 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; and a first mode switch device switching an operation mode of the hybrid vehicle from a normal mode in which the driving assist control and the gear shift assist control are performed to a battery power preserving mode in which the driving assist control is prohibited and the gear shift assist control is permitted in a case where the SOC value detected by the SOC value detection device is equal to or smaller than a first predetermined value.
