Hybrid vehicle and driving control method therefor

A driving control method for a hybrid vehicle including an engine, a motor, and a battery, the method comprising:

• determining acceleration force requirement based on manipulation of an accelerating pedal, and determining an engine target torque and a first target torque of the motor, for satisfying the acceleration force requirement, based on a driving state including states of the engine, the motor, and the battery, and a vehicle speed;
• determining brake force requirement based on manipulation of a brake pedal, and determining a target hydraulic pressure of a hydraulic brake and a second target torque of the motor, for satisfying the brake force requirement, based on states of a hydraulic brake system, the battery, and the motor;
• and
• determining a third target torque for implementing the brake force requirement by the motor in a state in which the engine maintains the engine target torque when the accelerating pedal and the brake pedal are simultaneously manipulated under a predetermined condition.

A hybrid vehicle comprising:

• a motor;
• an engine;
• and
• a hybrid controller configured to, when an acceleration request via manipulation of an accelerating pedal and a deceleration request via manipulation of a brake pedal are simultaneously made in a situation in which a predetermined condition is satisfied, implement the acceleration request as torque of the engine and to implement the deceleration request as regenerative brake torque of the electric motor.

A hybrid vehicle including an engine, a motor, and a battery, comprising a processor including:

• an acceleration operating point determination module configured to determine acceleration force requirement based on manipulation of an accelerating pedal and to determine an engine target torque and a first target torque of the motor, for satisfying the acceleration force requirement, based on a driving state including states of the engine, the motor, and the battery, and a vehicle speed;
• a brake force determination module configured to determine brake force requirement based on manipulation of a brake pedal and to determine a target hydraulic pressure of a hydraulic brake and a second target torque of the motor, for satisfying the brake force requirement, based on states of a hydraulic brake system, the battery, and the motor;
• and
• a sports operating point determining module configured to determine a third target torque for implementing the brake force requirement by the motor in a state in which the engine maintains the engine target torque when the accelerating pedal and the brake pedal are simultaneously manipulated under a predetermined condition.
