Abstract
A method of controlling an engine of a hybrid vehicle includes steps of calculating a maximum torque of an engine at which an engine lambda=1 is maintained; calculating a maximum dischargeable torque of a driving motor; and allowing an operation of the engine having the engine lambda<1 when a torque required by a driver is greater than a sum of the maximum torque of the engine at which the engine lambda=1 is maintained and the maximum dischargeable torque of the driving motor.
Claims10
A method of controlling an engine of a hybrid vehicle, comprising steps of:
- calculating a maximum torque of an engine at which an engine lambda=1 is maintained;
- calculating a maximum dischargeable torque of a driving motor;
- and
- allowing an operation of the engine having the engine lambda<1 when a torque required by a driver is greater than a sum of the maximum torque of the engine at which the engine lambda=1 is maintained and the maximum dischargeable torque of the driving motor.
1 more element
An apparatus for controlling an engine of a hybrid vehicle, comprising:
- an engine clutch arranged between an engine and a motor and configured to transmit or block power of the engine;
- an automatic transmission configured to shift and output power of the engine or power of the engine and the motor to the wheels;
- an inverter configured to control the motor and to control power generation;
- a high voltage battery connected to the inverter and configured to be chargeable and dischargeable so that power is provided to the motor;
- and
- a control unit configured to calculate a maximum torque of the engine at which an engine lambda=1 is maintained and a maximum dischargeable torque of the motor, and allow an operation of the engine having the engine lambda<1 when a torque required by a driver is larger than a sum of the maximum torque of the engine at which the engine lambda=1 is maintained and the maximum dischargeable torque of the motor.
