Abstract:
The present invention controls torque of a hybrid vehicle that calculates power and torque of each motor when the hybrid vehicle provided with two motors operates at a transient state are used. More specifically, target power of a battery is determined. Then calculations are performed to determine target torque of the first motor, target torque of the second motor, target torque of an engine, and target speed of the engine at a steady state. The torque of the first motor at a transient state is calculated from the target torque of the second motor at the steady state and speeds of the first and second motors. Finally, torque of the second motor at the transient state is calculated from the torque of the first motor at the transient state and the speeds of the first and second motors.
