When the driving mode is inputted to a stopping mode through the input and output module, based on an expected stop time, a current SOC of a battery, a target SOC of the battery, output of the driving motor, and output of the HSG, the controller that performs a first charging mode that charges the power generated by the engine in the battery through the driving motor and a second charging mode that charges the power generated by the engine in the battery through the driving motor and the HSG. ## Claims ### Claim 1 A control apparatus of a hybrid vehicle, comprising: an input and output module for a driver to select a driving mode, wherein the driver enters an expected stopped time into the input and output module; an engine that generates a power required for driving a vehicle by fuel combustion; a driving motor that generates power required for driving the vehicle, the driving motor being configured to operate as a generator; a hybrid starter-generator (HSG) that starts the engine and is configured to operate as a generator; and a controller configured to perform a first charging mode that generates power with the engine to charge the battery through the driving motor, and to perform a second charging mode that generates power with the engine to charge the battery through the driving motor and the HSG; wherein the controller performs the first charging mode when a time required to reach a target SOC from a current SOC by using the output of the driving motor is within the expected stopped time input by the driver, and wherein the controller performs the second charging mode when a time required to reach the target SOC from the current SOC through the output of the driving motor exceeds the expected stopped time input by the driver. ### Claim 2 (depends on 1) The control apparatus of the hybrid vehicle of claim 1, wherein in the first charging mode, the controller turns on the engine, and the driving motor converts power outputted from the engine into electrical energy to charge the battery. ### Claim 3 (depends on 1) The control apparatus of the hybrid vehicle of claim 1, wherein in the second charging mode, the controller turns on the engine, and the driving motor and the HSG convert power outputted from the engine into electrical energy to charge the battery. ### Claim 4 (depends on 2) The control apparatus of the hybrid vehicle of claim 2, wherein when a position where the vehicle is stopped is in an idling restricted zone, the controller charges the battery only for a set time in the idling restricted zone. ### Claim 5 A control method of a hybrid vehicle, comprising: receiving, by an input and output module, a driving mode of the hybrid vehicle; receiving, by the input and output module, an expected stopped time when the driving mode of the vehicle is in a stopped mode; determining, by a controller, a charging mode while the vehicle is stopped based on the expected stopped time, a current state of charge (SOC) of a battery, a target SOC, output of a driving motor, and output of an HSG; and charging the battery according to the charging mode while the vehicle is stopped; wherein when a time required to reach the target SOC from the current SOC by using the output of the driving motor is within the expected stopped time, the charging mode while the vehicle is stopped is determined to be the first charging mode; and wherein when a time required to reach the target SOC from the current SOC through the output of the driving motor exceeds the expected stopped time, the charging mode while the vehicle is stopped is determined to be the second charging mode. ### Claim 6 (depends on 5) The control method of the hybrid vehicle of claim 5, wherein the charging mode while the vehicle is stopped includes a first charging mode that charges the power generated by the engine in the battery through the driving motor and a second charging mode that charges the power generated by the engine in the battery through the driving motor and the HSG. ### Claim 7 (depends on 5) The control method of the hybrid vehicle of claim 5, further comprising: identifying, by a navigation device, an idling restricted zone on a driving route of the vehicle; and determining, by a GPS module, whether a position where the vehicle is stopped is the idling restricted zone. ### Claim 8 (depends on 7) The control method of the hybrid vehicle of claim 7, further comprising when the position where the vehicle is stopped is in the idling restricted zone, charging the battery for a limited time in the idling restricted zone.
