Abstract:
1. A hybrid vehicle having a brake function, comprising: a hybrid starter and generator (HSG) for starting an engine or generating electricity by the engine; a clutch disposed on a route for transmitting torque of the engine to a wheel, wherein the clutch selectively transmits the torque; a motor disposed at a rear side of the clutch on the route, wherein the motor adds torque or generates electricity; an inverter electrically connected to the HSG and the motor; a battery electrically connected to the inverter, wherein the battery stores or outputs electrical energy; a controller that releases the clutch, controls the motor to generate the electricity through the torque transmitted from the wheel to the motor, and controls the HSG to consume the electricity generated from the motor, if a braking demand condition is satisfied; wherein power supplied from the motor to the inverter is calculated by a motor efficiency, a motor braking torque, and a motor speed; wherein a mechanical braking power of the engine is calculated by an HSG efficiency and power supplied to the HSG; and wherein a target speed of the engine is calculated or selected by a predetermined map table according to the mechanical braking power.
