As a practical alternative, plug-in hybrid vehicles are being provided.

The plug-in hybrid vehicle may be divided into a discharge-oriented mode (CD mode) and a charge-oriented mode (CS mode) according to the state of charge (SOC) of the battery.

The discharge-oriented mode (CD mode) means an interval of an EV (Electric Vehicle) mode in which only the electric power charged in the battery is used to travel to the drive motor alone.

The charge-oriented mode (CS mode) refers to a period in which electric power charged in the battery is used up to a certain amount and then traveled in an appropriate combination of the driving force of the engine and the driving motor in the same manner as in the HEV (Hybrid Electric Vehicle) mode.

In the plug-in hybrid vehicle, since the SOC (State Of Charge) of the battery is good in the discharge-oriented mode (CD mode), the usable electric quantity is large.

However, in the charge-oriented mode (CS mode), since the SOC of the battery is insufficient and the usable electricity amount is relatively small, the driving force of the engine and the driving motor is combined with each other. Thus, fuel efficiency is improved, .

The same driving strategy as that of the charging-oriented mode (CS mode) is executed according to the road condition or the driver's will in a state in which the plug-in hybrid vehicle is driven in the discharge-oriented mode (CD mode) You may want to.

However, in the present plug-in hybrid vehicle, there is no control strategy for entering the charge-oriented mode (CS mode) while the vehicle is running in the discharge-oriented mode (CD mode) Mode) can not be obtained.

And when the discharge limit value of the battery is equal to or greater than the entry boundary value of the charging mode (CS mode), it activates the sports driving map and forcibly enters the charging mode (CS mode) to control the output torque of the driving motor and the engine, ;
Wherein the charge-oriented mode forced entry method of the plug-in hybrid vehicle comprises: 11. The method of claim 10,
Wherein the battery charge state (SOC1) and the charge / discharge limit value (X1, Y1) are binarized and managed when the sport mode is selected during driving in the discharge-oriented mode (CD mode). 11. The method of claim 10,
If the battery charge state SOC1 and the charge / discharge limit values X1 and Y1 which are managed in the sport mode are detected to be equal to or lower than the boundary value between the discharge direction mode (CD mode) and the charge direction mode (CS mode) (CS mode) in which the vehicle is forcedly entered in one state, and is controlled to a normal charge-oriented mode (CS mode). An engine and a drive motor as power sources;
A battery manager for managing a charged state of the battery and a charge / discharge limit value;
A hybrid controller for controlling travel of a discharge-oriented mode (CD mode) or a charge-oriented mode (CS mode) by applying a charge state of the battery and a charge / discharge control value;
Lt; / RTI >
Wherein the hybrid controller is configured such that software for executing at least one of the control of at least one of the seventh to twelfth aspects is set.
